Abstract

Systems and methods for implement an item lockout at a vending machine. For example, an item may be locked out due to a recall associated with the item. The systems and methods include detecting a lockout request indicating an item type. The systems and methods also include querying an inventory database to identify items associated with the item type. The inventory database is configured to store item records of items offered by a vending machine and store a status of the items offered by the vending machine. Additionally, the systems and methods include changing a status of the items associated with the item type to indicate that the items are locked out. Changing the status of the items prevents the corresponding items from appearing in a list of available items.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS
• This application claims priority to U.S. Provisional Patent Application No. 62/626,292 entitled “Perishability Prevention Platform Systems” and filed on Feb. 5, 2018 and U.S. Provisional Patent Application No. 62/684,342 entitled “Profitable Perishability Prevention Platform Systems” and filed on Jun. 13, 2018, the entirety of both of which are incorporated by reference herein.
BACKGROUND
• The present disclosure generally relates to an inventory control system for providing a network of vending machines with a controlled atmosphere for storage and purchase of fresh food.
• Conventionally, vending machines provide bottled drinks and small snack food. However, there is a need for selling a variety of fresh food including fresh fruit and vegetables. Yet, such market need is not met owing primarily to the short shelf life of fresh food and the cost of frequently replenishing the fresh food, not to mention the increase in food waste when the fresh food is not consumed before its end of shelf life. For example, one-fourth of the food a restaurant purchases is wasted, one-third of the food that an individual purchases is wasted, and one-tenth of the food that a grocery store purchases is wasted. Additionally, vending machines that sell fresh food need mechanisms to ensure that customers do not purchase expired food.
• Conventional technologies (e.g., using preservatives, modified atmosphere packaging, etc.) that are designed to extend the shelf life of fresh products negatively impact the quality and directly affect the integrity of the product. For example, modified atmosphere packaging is a specific blend of atmospheric gases used in conjunction with a semi permeable film designed to slow the product aging process to improve the shelf life. However, incorporating modified atmosphere packaging is expensive and only temporarily solves the problem by merely extending the shelf life by a number of days and does not prevent the vending of expired or otherwise improperly sellable food.
SUMMARY
• The present disclosure provides an inventory control system for providing a network of vending machines with a controlled atmosphere for storage and purchase of fresh food. The inventory of the vending machines may be refreshed automatically based on the feedback from the vending machine and/or manually from a vending machine operator (e.g., delivery driver). In some embodiments, the system includes dynamic pricing of the food items to influence the purchase behavior of consumers to move certain inventory and maximize revenue and minimize loss. For example, the price of a food item may be decreased as the food item nears its expiration date.
• According to disclosed embodiments, a management server monitors inventory stored across the network of vending machines. In some implementations, the management server is a cloud computing platform comprised of a plurality of disparate servers acting in conjunction with one another to distributively perform the functionality described herein. In some embodiments, the management server enables client devices to remotely reserve vending machine inventory for pick up at a later time. For example, the client device may request to reserve a particular product at a particular vending machine. If the vending machine has sufficient inventory, the management server may associate the reservation with a unique identifier pickup code that the user may input to the vending machine to cause the vending machine to vend the reserved item. If not, the management server may recommend completing the reservation at a second vending machine within the network of vending machines that does have sufficient inventory.
• Enabling remote reservations of vending machine inventory creates a race condition associated with processing contemporaneous requests for a particular item offered by a vending machine. For instance, if there is only one cobb salad remaining in the vending machine, a customer physically interacting with the vending machine may be attempting to purchase the cobb salad when a remote request to reserve the cobb salad is received. Accordingly, in one embodiment, when a customer is interacting with a vending machine, the vending machine inventory control system disables the remote reservation functionality to prioritize the physical customer. Similarly, the inventory control system restores the remote reservation functionality when the physical customer has completed their interaction with the vending machine. In these embodiments, the management server and/or the vending machine creates a reservation queue storing pending reservation requests until the inventory control system restores the remote reservation functionality. Upon restoration of the remote reservation functionality, the reservation requests in the queue are sequentially released for processing by the vending machine inventory control system. By implanting disclosed embodiments, vending machines are capable of offering remote reservations, and in some embodiments, in a manner that preserves the vending machine experience for physically-present customers.
• According to embodiments disclosed herein, the inventory control system prevents the vending of expired items. In some embodiments, the inventory control system associates food items stored therein with expiry data. Accordingly, the inventory control system can prevent food items that are expired from being sold to customers. Similarly, in some scenarios, a particular item may be recalled by a supplier. Accordingly, the management server may analyze the inventory of the vending machine network to identify any vending machines that have the recalled item in inventory. The management server may then transmit a recall notice to the impacted vending machines. Upon receipt of the recall notice, the vending machine prevents the vending of the recalled item. By implementing these embodiments, vending machines are capable of offering perishable items while still ensuring that customers are unable to purchase expired or recalled products.
• According to other embodiments, to reduce the downtime associated with restocking vending machines, the vending machine may include an automatic unloading routine. That is, upon receiving an unloading command, the vending machine may be configured to dispense any expired or recalled product for disposal by a service professional. In some embodiments, the service professional is associated with a service electronic device (for example, a phone, a tablet, a phablet, smart glasses, a smart watch, a device connected to a service vehicle, such as via an on-board diagnostic port, etc.). In some embodiments, when the service electronic device is brought within communicative range (e.g., within range of a Wi-Fi or Bluetooth transceiver) of the vending machine, the service electronic device automatically establishes a connection with the vending machine and transmits the unloading command. In other embodiments, the management server associates the vending machine with a geofence. Accordingly, the service electronic device may be configured to periodically report its location to the management server. If the management server detects that the service electronic device is within the vending machine's geofence, the management server may transmit the unloading command to the vending machine. In still other embodiments, the service electronic device may present a user interface element that enables the service professional to manually transmit the unloading command to a vending machine, either directly, or via the management server.
• Additional objects, advantages and novel features of the examples will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following description and the accompanying drawings or may be learned by production or operation of the examples. The objects and advantages of the concepts may be realized and attained by means of the methodologies, instrumentalities and combinations particularly pointed out in the appended claims.

DETAILED DESCRIPTION
• Referring to the figures in detail,FIG. 1 illustrates anexample environment100 that includes avending machine115 connected to anetwork120. Although,FIG. 1 illustrates asingle vending machine115, theenvironment100 may include any number ofadditional vending machines115 to form a network of vending machines that provide fresh food. Eachvending machine115 is a self-service unit that combines electro-mechanical dispensing components, network connectivity, and a user interface for customer interaction. In some implementations, the dimensions of thevending machine115 enables placement of thevending machine115 in high-traffic locations that are more convenient than traditional retail locations.
• Thevending machine115 can be any suitable vending machine. For example, thevending machine115 may also include a storage system for holding individual food products for purchase. The storage system may include a plurality of slots adapted to store a plurality of individually dispensable items loaded therein. The slots may be substantially horizontal, such as embodiments that include a conveyor belt, shelf, or coil, or substantially vertically. In an example, each individual storage unit of the slot is associated with a sensor and/or a slot location identifier.
• Thevending machine115 may also include an atmospheric control system that includes a variety of sensors and controllers for temperature, air composition, and/or humidity control. The temperature control components may include a cooling or refrigerating apparatus, a heating or warming apparatus, and/or other temperature control apparatuses to maintain a desired temperature associated with the items stored therein. For example, some fresh foods are best stored between 35-40° F. (1.66-4.44° C.). On the other hand, frozen food may be best stored between −5-0° F. (−20.26-−17.78° C.). In some embodiments, the vending machine includes different temperature control apparatus to regulate the temperature of different slots. A temperature control apparatus may include one or more sensors to provide feedback to a regulator of the temperature control apparatus. According to certain aspects, the atmospheric control system may be controlled by a remote system such as amanagement server125.
• Thevending machine115 may also include a point of sale system. In some embodiments, the point of sale system includes one or more mechanisms to receive a customer selection of a particular item. For example, the selection mechanisms may include one or more buttons and/or a touch screen display. Additionally, the point of sale system of thevending machine115 may include a payment system adapted to receive and/or process cash, gift cards, promotions, customer account credits, and/or credit cards. Thevending machine115 may also include a merchandise selector including a user interface, key pad, and/or switches for customers to select the desired item for purchase. According to certain aspects, the inventory control system of thevending machine115 implements dynamic pricing of items to generate prices and promotions to influence the purchase behavior of consumers to move certain inventory and maximize revenue and minimize loss.
• As illustrated inFIG. 1, thevending machine115 is in communication with themanagement server125 via thenetwork120. Thenetwork120 may facilitate any type of data communication via any current or future-developed standard or technology (e.g., GSM, CDMA, TDMA, WCDMA, LTE, EDGE, OFDM, GPRS, EV-DO, UWB, IEEE 802 including Ethernet and Wi-Fi, WiMAX, Bluetooth, and others). In some embodiments, thenetwork120 utilizes two or more of the communication standards or technologies. For example, thevending machine115 may communication with themanagement server125 via a IEEE 802 connection and a serviceelectronic device110 via a Bluetooth connection.
• In some embodiments, the inventory control system of thevending machine115 is configured to dynamically monitor inventory within thevending machine115. In one example, the inventory management system of thevending machine115 communicates the current inventory to themanagement server125 to maintain a central record of the inventory. In this example, the inventory update may include a sale record associated with the change in inventory. In some embodiments, thevending machine115 monitors the inventory based on a sensor associated with the various item slots. When an item is purchased, the inventory control system detects corresponding sensor data that indicates that the item is no longer within thevending machine115. In other embodiments, the inventory control system monitors transaction data from the point of sale system to update an inventory record accordingly. According to aspects, the transaction data may also include customer data such as demographic data, customer profile information, addressing information (including an identity and/or address of a customer electronic device105), and so on.
• According to aspects, the allocation of inventory to thevending machine115 may be regulated by themanagement server125, such as by increasing inventory for high volume locations or days. Similarly, themanagement system125 may modify inventory allocation based on product data, customer feedback, and sales ofvending machines115. In an example, themanagement server125 forecasts production allocation based on the vending machine location, demographics, and purchase history. Based on this forecast, themanagement server125 may automatically generate a replenishing product list to be delivered the next day (or any suitable regular time intervals) to replenish the inventory of thevending machine115. Further, if the system detects a particular item has increased in sales at thevending machine115, themanagement server115 can suggest or add similar items to the inventory of thevending machine115. Similarly, themanagement server125 may also suggest or add items to the inventory of other vending machines located near thevending machine115. For example, if a particular salad has increased in sales, themanagement server125 may increase in the inventory of that particular salad by increasing a count of the salad in the inventory list of items to be delivered to the vending machine115 (or other vending machines115) during the next interval.
• According to aspects, the inventory themanagement server125 allocates to thevending machine115 may be automatically updated in regular time intervals and/or continually in real time based on the transaction records and/or inventory reports received from thevending machine115. In some embodiments, themanagement server125 generates promotional prices to be implemented at thevending machine115. For example, based on the feedback of thevending machines115, themanagement server125 may generate customized promotions (e.g., advertisements, coupons, etc.) that are sent to one ormore customer devices105 via thenetwork120. In some implementations, the promotions are targeted based on customer data maintained at themanagement server125. For example, based on the inventory loss data and the customer data, themanagement server125 may generate and transmit a discount promotion via a push notification or text message to targetedcustomer devices105.
• As another example, themanagement server125 analyzes transaction data to identify trends. For example, the transaction data may indicate that women tend to buy a particular sandwich. Accordingly, themanagement server125 may generate a promotion for the sandwich that is targeted towards female customers. Similarly, the transaction data may indicate that customers of a particular age range tends to purchase a particular wrap. Accordingly, themanagement server125 may update the inventory list to increase the number of wraps for the vending machine115 (assuming thevending machine115 is located in a region that has a large customer base in that age group).
• As another example, the inventory control system of thevending machine115 maintains expiration data with the inventory. For example, the expiration data may be include a stock date, a shelf life, and/or an expiration date. In some embodiments, thevending machine115 synchronizes the expiration data with themanagement server125. Accordingly, themanagement system125 may determine that a particular item is approaching its expiration date and generate a customized promotion for the particular item. The generated promotion can be sent to a targeted set ofcustomer devices105 to incentivize the customers to purchase the particular salad before it must be removed as food waste. Theconsumer device105 may be targeted based on demographic data, prior purchase history, or other data attributes.
• The combination of the production allocation forecasting, the vending machine inventory feed data, the automated customer relationship management, and the customized promotion generation enables themanagement server125 to support the distribution of fresh food products with short shelf life available at all times in a profitable manner.
• In some embodiments, the customerelectronic devices105 execute an application configured to interact with features of themanagement system125 and/or thevending machine115. The customerelectronic devices105 may include any electronic device that supports user interactions and the ability to communicate over thenetworks120. For example, the customerelectronic device105 may be a smartphone, a desktop computer, a laptop, a tablet, a phablet, a smart watch, smart glasses, wearable electronics, a home assistant device, and so on. In some embodiments, the customerelectronic device105 supports voice-based interactions for obtaining indications user inputs that control operation of the application. In some scenarios, the application is a dedicated application for interacting with the features of themanagement server125. In other scenarios, the application is a browser application executing instructions associated with a website tailored to support the features of themanagement server125.
• In some embodiments, the application enables the customerelectronic device105 to interact with themanagement server125 to order or reserve an item from thevending machine115. Accordingly, the application causes the customerelectronic device105 to transmit an inventory query to themanagement server125, and in response receive an inventory list based on the inventory data maintained bymanagement server125 corresponding to thevending machine115. In some scenarios, the inventory query includes location data corresponding to the customerelectronic device105 such that the management server may analyze the inventory list ofvending machines115 located proximate to the customerelectronic device105. For example, customerelectronic device105 may transmit an inventory query for a specific salad and themanagement system125 may determine avending machine115 closest to the customerelectronic device105 that has the salad available for purchase.
• According to aspects, the application also causes the customerelectronic device105 to transmit an electronic identification (e.g., phone number, credit card, user name identification, email address, device identifier, IP address, etc.) to themanagement server125. Themanagement server125 may utilize the electronic identification to track a purchase history associated with the customer. If themanagement system125 detects that the electronic identification is associated with a new customerelectronic device105 and/or customer, themanagement server125 may prompt the customer electronic device to present a user interface adapted for creating a user profile. As a result, subsequent purchases may occur faster and more efficient. Further, the user profile enables themanagement system125 to transmit product suggestions and/or promotions o the customerelectronic device105 based on the customer's purchase history, demographics, location, and/or other data attributes in a customer profile.
• In some embodiments, to ensure food safety, themanagement system125 and/or thevending machine115 may prevent the purchase of particular items sold in thevending machine115. As one example, if the temperature of thevending machine115 is below or above a certain threshold for a certain time, thevending machine115 locks out temperature-sensitive products from being sold. To this end, the inventory data associated with each product may include a range of suitable storage temperatures. If the temperature is outside of the suitable temperature range for a particular item, the vending machine may prevent purchase of the particular item. In this example, thevending machine115 may still provide for purchase other items for which the temperature range is still within the suitable temperature range.
• As another example, themanagement system125 may monitor the temperature of thevending machine115 and/or the items therein. Accordingly, thevending machine115 may periodically transmit temperature readings over thenetwork120 to themanagement server125. If themanagement system125 detects the temperature is outside of the suitable temperature range for a particular item, themanagement system125 may alert a technician by transmitting a maintenance request to a serviceelectronic device110. If a technician does not arrive and complete the maintenance on the system within a given time (e.g., 1 hour, 2 hours, 4 hours, etc.), themanagement system125 transmits a lockout command to thevending machine115 to prevent the purchase of items outside of the suitable temperature range. Therefore, customers cannot purchase any items that have been exposed to improper temperatures for a length of time that would render the item unsafe for consumption.
• According to certain aspects, themanagement system125 may be configured to block the purchase of particular items based on a product recall and/or complaint. For example, a supplier or a government agency may recall a particular item due to a defect or risk of contamination. Accordingly, themanagement server125 may receive a notification that a particular item has been recalled and should not be sold. Themanagement server125 may then transmit over thenetwork120 an item lockout command to anyvending machine115 that includes the item in inventory. In response to receiving the lockout command, thevending machine115 may prevent the purchase of that item. Additionally, themanagement server125 may prevent customerelectronic devices105 from purchasing the recalled item. Further, themanagement system125 may notify one or more customerelectronic devices105 that have previously purchased the recalled item. In some implementations, the notification includes a promotion, coupon, or credit to their account to reimburse the customer for the purchased item.
• In another example, themanagement system125 may block the purchase of an item reserved via customerelectronic device105. Accordingly, themanagement system125 may associate the reserved item with a purchase code. Themanagement server125 may then push the purchase code to thevending machine115. Thevending machine115 may then only dispense the reserved item upon receiving an input of the purchase code. Other attempts to purchase the reserved item are blocked by thevending machine115.
• As illustrated inFIG. 1, the serviceelectronic device110 is also in communication with themanagement server125 and/or thevending machine115 via thenetwork120. In some embodiments, the serviceelectronic device110 is a personal electronic device (e.g., smartphone, tablet, smart watch, etc.) carried by service personnel. In other embodiments, the serviceelectronic device110 is embedded in a vehicle operated by service personnel. In these embodiments, the service electronic device may establish a communication link with a personal electronic device of the service personnel.
• In one embodiment, themanagement system125 and/or thevending machine115 establishes a geofence around thevending machine115. As it is generally use herein, the term “geofence” refers to a geographical boundary established surrounding thevending machine115. In some embodiments, the geofence is established based on a positioning system (e.g., GPS). In other embodiments, the geofence is established based on network connectivity (such as the ability to detect the presence of a broadcast identifier or a signal strength or quality metric above a threshold level). In some implementations, when themanagement system125 and/or thevending machine115 detects the presence of the serviceelectronic device110 within the geofence, thevending machine115 may automatically unload expired or otherwise unsellable products. Automatic unloading reduces the downtime associated with the driver manually unloading the machine of its unsellable products as part of the restocking process.
• According to aspects, themanagement system125 transmits inventory notifications to the serviceelectronic device110 to indicate restocking instructions for thevending machine115. Thus, upon arriving at the location of thevending machine115, the driver can follow instructions indicated by the service electronic device. For example, the restocking instruction may indicate which items in the vending machine need to be removed, as well as which new food items to place into the vending machine for purchase. In some implementations, the instructions are displayed in a planogram format such that the service personnel is able to readily determine item location within thevending machine115.
Example Vending Machine
• Turning toFIG. 2, illustrated is anexample vending machine215, such as thevending machine115 ofFIG. 1, at which functionality described herein is implemented. Thevending machine215 includes one or more processors, such as the depicted central processing unit (CPU)202. Although not depicted, the vending machine may also include a graphics processing unit (GPU). During operation, theCPU202 executes instructions stored in aprogram memory module240 coupled to theCPU202 via asystem bus222. In some implementations, theprogram memory module240 is implemented in a random access memory (RAM)module218, apersistent memory module230, or both. Theprogram memory module240 may also store computer-readable instructions that regulate the operation of the vending machine. One set of instructions may be aninventory control application242 that contains instructions to facilitate inventory control functionality. For example, theinventory control application242 may maintain an accurate record of the various items stored at thevending machine215. This record may be maintained at theinventory database232 of thepersistent memory230. The records in theinventory database232 may include indications of an item identifier, a stock keeping unit (SKU) identifier, a location (such as a slot identifier), expiration data, an item status (e.g., available, reserved, expired, locked, sold, etc.), and so on. In some embodiments, theinventory database232 also includes SKU-based records that include indications of SKU quantity, a cost, SKU status (e.g., normal, recalled, promoted, etc.). The SKU-based records may be automatically update in response to changes to item records. For example, when theinventory control application242 updates an item record to indicate that a particular item has been sold, the SKU-record may automatically decrement a quantity parameter.
• As another example, the slot identifier associated with the item or SKU records may be determined based upon a storedplanogram236. Theplanogram236 is a “map” that associates the various slots of thevending machine215 with particular items or SKUs. In some embodiments, updates to theplanogram236 are transmitted by a management server to thevending machine215 for local storage. In these embodiments, theplanogram236 may also be transmitted to a service electronic device such that service personnel may maintain the vending machine inventory in accordance with theplanogram236. In other embodiments, each individual item is uniquely tagged (such as with an RFID tag or a QR or other barcode). In these embodiments, thesensors208 detect the location of the various items to dynamically update theplanogram236. Additionally, theinventory control application242 may transmit updates to theplanogram236 to the management server to synchronize back-end systems.
• As illustrated inFIG. 2, theinventory control application242 may also controlvending actuators214 to vend a particular item. It should be appreciated that in other embodiments, control of thevending actuators214 is processed by a separate application. Thevending actuators214 may be any actuator that controls a vending mechanism (e.g., a coil, a conveyor belt, a motorized shelf, a grabbing arm, a suction unit, etc.). In some embodiments, thevending actuators214 include a separate controller configured to interpret control signals generated by theinventory control application242 and transmitted over thesystem bus222. For example, in response to detecting a purchase event for a Napa salad, theinventory control application242 may query theinventory database232 to detect a slot that stores a Napa salad and generate a vending command that indicates the slot identifier. The controller of thevending actuators214 may include a queue to process multiple vending commands associated with a multi-item order.
• In some embodiments, theinventory control application242 also maintains areservation database234 that includes a list of items remotely reserved via interactions with a management server. Each reservation may indicate the item and a purchase code utilized to pick up a reserved item. After the item has been picked up, theinventory control application242 removes the reservation from the reservation database. In some implementations, theinventory control application242 monitors a duration a particular reservation has been in thereservation database234. If the duration exceeds a threshold duration, theinventory control application242 may transmit an indication to a management server to take a remedial action.
• As another example, theinventory control application242 may detect a signal from a management server to prevent the sale of a particular item. In response, theinventory control application242 may modify the status of the item such that other applications (such as the point of sale application246) do not include the particular item in a list of available items. As yet another example, theinventory control application242 may detect a signal to automatically unload one or more items. In response, theinventory control application242 may analyze theinventory database232 to detect any items associated with a status that indicates the item is unsellable (e.g., expired or recalled). Theinventory control application242 may then generate a control signal for thevending actuators214 for each unsellable item.
• Theprogram memory240 may also include a set of instructions that comprises anatmosphere control application244. Theatmosphere control application244 may control the operation of theatmosphere control units224 via instructions transmitted over thesystem bus222. The atmosphere control units may include refrigeration units, heating units, humidifiers, oxygenators, and/or any other mechanism that controls the atmospheric environment within thevending machine215. In some embodiments, theatmosphere control application244 divides the vending machine into different climate zones to maintain multiple atmospheric environments simultaneously. Accordingly, theatmosphere control application244 may utilize the output ofsensors208 to generate appropriate control signals for theatmosphere control units224.
• Theprogram memory240 may also include a set of instructions that comprises a point ofsale control application246 configured to support the ordering of items and the processing of payments at thevending machine215. The point ofsale control application246 may be configured to cause adisplay unit212 to present one or more interfaces that guide a customer through the purchase process. Thedisplay unit212 may include a touch-screen display for receiving user input. In some embodiments, the point ofsale control application246 may query theinventory database236 to populate the interfaces with indications of the available inventory. As part of the payment process, the point ofsale control application246 monitors inputs at acard reader216 to detect credit card information for completing the purchase.
• In addition to programs, theRAM module218 and thepersistent memory module240 may store data in a volatile or non-volatile mode, respectively. TheRAM module218 and thepersistent memory module240 further include one or more forms of fixed and/or removable memory, such as read-only memory (ROM), electronic programmable read-only memory (EPROM), RAM, erasable electronic programmable read-only memory (EEPROM), and/or other hard drives, flash memory, MicroSD cards, and others. For example, theinventory database232, thereservation database234, and theplanogram236 may be stored as data structures in thepersistent memory module230.
• Thevending machine215 may further includetransceivers204 that enable thevending machine215 to send and receive data over a wireless or wired network (such as thenetwork120 described with respect toFIG. 1). Thetransceivers204 may include one or more transceivers (e.g., WWAN, WLAN, WPAN, EVDO, CDMA, GSM and/or LTE transceivers) functioning in accordance with IEEE standards, 3GPP standards, or other standards. In some embodiments, when the point ofsale application246 detects a customer interacting with thedisplay unit212, the point ofsale application246 may disable thetransceivers204 to prevent the reception of new reservations. Similarly, after the point ofsale application246 detects that the customer is no longer interacting with the display unit212 (e.g., by detecting a sales event or the expiration of a usage timer), the point ofsale application246 re-enables thetransceivers204. In alternative embodiments, in response to detecting the customer interaction, the point ofsale application246 establishes a queue for requests received via thetransceivers204. Upon detecting that the customer is no longer interacting with thedisplay unit212, the point ofsale application246 processes requests in the established queue. In still further embodiments, the point ofsale application246 may both disable thetransceivers204 and establish a queue for new requests (e.g., by transmitting a queue command to the management server).
• It should be appreciated that thevending machine215 may include additional or fewer components than what is depicted byFIG. 2. For example, the vending machine may include keys, mice, buttons, or other physical input devices to facilitate user interactions with thevending machine215. As another example, thevending machine215 may include one or more external ports or other components that enable service personnel to interact with thevending machine215, such as a USB or other port via which a service electronic device can be connected to transmit diagnostic messages for troubleshooting and/or maintenance activities. As yet another example, thevending machine215 may include one or more cameras, scanners, or other sensors connected to track the items stored at thevending machine215 and/or to support security surveillance, stock monitoring, scanning customer electronic devices, and/or customer biometric recognition, for example.
Reserve and Pay
• FIGS. 3 and 4 illustrate flow diagrams300 and360, respectively, associated with a process for customers to remotely reserve items at a vending machine, such as thevending machines115 or215 ofFIGS. 1 and 2, respectively. The management server and the vending machine may be in communication with one another over one or more networks, such as thenetworks120 ofFIG. 1. The flow diagram300 illustrates the process for reserving a particular item; whereas the flow diagram360 illustrates the process for picking up a reserved item.
• Theprocess300 begins when a management server (such as themanagement server125 ofFIG. 1) and the vending machine (labeled as Fridge Y) synchronize (step330) the inventory maintained at Fridge Y. As described above, Fridge Y includes an inventory database332 (such as theinventory database232 ofFIG. 2) that includes one or more records associated with items stored at the Fridge Y. In some scenarios, as the inventory at Fridge Y changes, Fridge Y transmit indications to the management server to synchronize the inventory. In other scenarios, the management server periodically polls Fridge Y to synchronize the inventory. In any event, the management server may maintain an inventory cache of available items located at Fridge Y. The cache may indicate an identifier of any available items and a corresponding quantity available. It should be appreciated that whileFIG. 3 only depicts an example inventory cache for Fridge Y, the inventory cache may include an available item list for any number of vending machines within the network of vending machines.
• According to aspects, a customer interacts with a customer electronic device (such as the customerelectronic device105 ofFIG. 1) to begin the item reservation process. To populate a user interface presented by the customer electronic device, the customer electronic device transmits (step331) a request to the management server to retrieve the inventory at Fridge Y. The request may be transmitted over one or more communication networks, such as thecommunication network120 ofFIG. 1. In response, the management server accesses the inventory cache to retrieve the list of available items at Fridge Y and transmits the list to the customer electronic device. In the illustrated scenario, the customer interacted with the user interface to view the inventory specifically at Fridge Y. However, in other scenarios, the request may instead include location data which is interpreted by the management server to identify a set of vending machines proximate to the location of the customer electronic device.
• The customer may then navigate user interfaces that indicate the inventory of the Fridge Y to reserve a particular item stored at Fridge Y. In some embodiments, the user interfaces are navigated by one or more voice inputs. As part of the reservation process, the customer electronic device may prompt the customer to enter a payment information to obtain payment information to be utilized to hold the reservation (i.e., a payment token). After the reservation information is collected by the customer electronic device, the customer electronic device transmits (step333) a reservation request to the management server. As illustrated, the reservation request includes an indication of the particular items, an indication of the vending machine, an indication of the customer, and an indication of the payment token.
• Upon receiving the reservation request, the management server creates a record at a reservation database corresponding to the reservation request. As part of creating the record, the management server may assign the reservation a randomly-generated unique identifier purchase code for the reservation. Additionally, the reservation record may include a reservation status. When the reservation record is first created, the management server may set the reservation status to be “Pending.”
• As described herein, to preserve the in-person experience for users of Fridge Y, if a customer is interacting with Fridge Y, Fridge Y may deactivate its capabilities for receiving new reservations. Accordingly, the management server may communicate with Fridge Y to determine if Fridge Y is currently capable of receiving new reservations. If not (e.g., one or more transceivers of Fridge Y are disabled), the management server establishes areservation queue327 of pending reservations associated with Fridge Y at the management server. The management server then stores (step336) the reservation request in thequeue327. It should be appreciated that any additional reservation requests received by the management server for items at Fridge Y prior to Fridge Y restoring reservation capabilities are also stored in thequeue327. Accordingly, when Fridge Y restores the reservation capabilities (e.g., the one or more transceivers of Fridge Y are re-enabled), the reservation requests are processed in the order they are received. It should be appreciated that whileFIG. 3 illustrates thequeue327 being maintained at the management server, other implementations may maintain thereservation queue327 at Fridge Y. In these implementations, Fridge Y may route all new requests to thequeue327 instead of disabling the one or more transceivers.
• Atstep338, Fridge Y detects whether there is customer activity at Fridge Y. For example, customer activity may be detected by determining that a user is interacting with a display unit at Fridge Y or by analyzing camera data. If there is customer activity, Fridge Y will continue to ignore any reservation in the queue327 (e.g., the management server continues to hold the reservations in the queue327). Once there is no longer customer activity, Fridge Y may transmit an message to the management server to release reservations held in thequeue327. Accordingly, Fridge Y sequentially receives and reads (step340) the pending reservations from thequeue327. As part of processing the reservation, Fridge Y queriesinventory database332 to determine (step342) whether Fridge Y has sufficient inventory to fulfill the reservation. If Fridge Y does not have sufficient inventory, Fridge Y sends (step352) a reservation failed status update to the management server. On the other hand, if Fridge Y does have sufficient inventory, Fridge Y adds the reservation to a reservation database334 (such as thereservation database234 ofFIG. 2). Fridge Y then sends a notification to the management server indicating that Fridge Y has sufficient inventory to process the reservation a transmits a unique identifier pickup code to the customerelectronic device105 ofFIG. 1. This process may repeat for each reservation in thequeue327.
• Upon receiving the notification that Fridge Y is able fulfill the reservation, the management server attempts to process (step346) payment using the payment token included in the reservation request atstep333. Atstep348, the management server determines whether the payment token was successfully processed. If the payment token was successfully processed, the management server sets (step350) a status flag indicate the success. The management server may also transmit a notification of the failure to Fridge Y to indicate that Fridge Y should remove the reservation from thereservation database334. On the other hand, if the payment token was not successfully processed, the management server sets (step352) the status flag to indicate the failure. Atstep354, the management server updates the reservation database to indicate the determined reservation status.
• The management server then transmits (step356) a notification to the customer electronic device indicative of the reservation status. In some embodiments, the notification is a push message formatted in compliance with an application programming interface (API) of the reservation application executing on the customer electronic device. In other embodiments, the notification is a text message. If the reservation was successful, the notification includes an indication of the purchase code. In some embodiments, the purchase code is included as text displayed on the screen of the customer electronic device. Additionally or alternatively, the purchase code may be embedded in a barcode or QR code and/or stored in local memory for transfer via a near field communication (NFC) or other short range transmitter.
• Turning now to theflow chart360 illustrated inFIG. 4, at some point after the completion of theprocess300, auser307 of the customer electronic device interacts with Fridge Y. As part of the interaction, the vending machine315 receives an indication that theuser307 has reserved an item and presents an interface enabling theuser307 to input (step362) the purchase code. The interface may include a text box for reception of a string, a camera interface configured to read a barcode or QR code displayed on the screen of the customer electronic device, or enable a NFC or other short range receiver to detect the transmission of a file indicating the purchase code.
• In response, Fridge Y utilizes the purchase code to query thereservation database334. More particularly, Fridge Y determines (step368) whether the received purchase code matches a purchase code associated with a reservation stored at thereservation database334. If the purchase code matches a purchase code of a stored reservation, Fridge Y issues (step366) commands that cause Fridge Y to vend any items included in the matching reservation record. On the other hand, if the received purchase code does not match a purchase code of a reservation stored in thereservation database334, Fridge Y may present (step368) an indication the purchase code is either invalid or expired. To this end, the reservation may include an indication of a time at which the reservation expires. If Fridge Y detects the reservation expiration without receiving the corresponding purchase code, Fridge Y may modify the record of the reservation at thereservation database334 to indicate that the purchase code is expired.
• FIG. 5 illustrates anexample method400 for implementing the reserve and pay functionality described herein. Themethod400 is implemented by a vending machine, such as thevending machines115 and215 ofFIGS. 1 and 2, respectively or Fridge Y ofFIG. 3.
• Themethod400 may begin when the vending machine detects a reservation request received via one or more transceivers (block402). The reservation request indicates a list of items and a purchase code. In order to prevent a race condition between local and remote users of the vending machine, some embodiments include detecting the presence of a customer at the vending machine. Responsive to detecting the presence of the customer at the vending machine, the vending machine may prevent the detection of the reservation request, such as by disabling the one or more transceivers. Similarly, the vending machine may detect when the customer is no longer present at the vending machine. Responsive to detecting that the customer is no longer present, the vending machine may then enable the ability of the vending machine to detect the reservation request, such as by enabling the one or more transceivers.
• Atblock404, the vending machine queries an inventory database (such as theinventory databases232 and332 ofFIGS. 2 and 3, respectively) to determine that the list of items are available. Atblock406, the vending machine generates a record in a reservation database (such as thereservation databases234 and334 ofFIGS. 2 and 3, respectively) with a unique identifier purchase code.
• Atblock408, the vending machine receives an input indicative of the unique identifier purchase code. The input unique identifier purchase code may be received via a display unit, a camera, and/or a transceiver. Atblock410, the vending machine queries the reservation database to identify a reservation record that includes a unique identifier purchase code that matches the input unique identifier purchase code. Atblock412, the vending machine issues a command to vend the list of reserved items included in the identified reservation record.
Automatic Unloading
• FIG. 6 illustrates anexample method420 for implementing the automatic unloading functionality described herein. Themethod420 is implemented by a vending machine, such as thevending machines115 and215 ofFIGS. 1 and 2, respectively or Fridge Y ofFIG. 3.
• Themethod420 begins when the vending machine detects the presence of a service electronic device (such as the serviceelectronic device110 ofFIG. 1) within a threshold distance of the vending machine. In some embodiments, the threshold distance is defined by a geofence surrounding the vending machine. In these embodiments, a management server, such as themanagement server125 ofFIG. 1 may maintain the geofence. That is, the service electronic device may transmit location as determined by a positioning system (e.g., GPS) to the management server, which determines whether the received location is within the geofenced region. It should be appreciated that while some geofences may be circular, the geofenced region may take any shape. When the received location is within the geofenced region, the management server transmits an indication to the vending machine that the service electronic device is within the threshold distance.
• In other embodiments, the vending machine determines whether the service electronic device is within the threshold distance by determining that the service electronic device is within a broadcast range of a particular transceiver of the vending machine. For example, one of the transceivers may be a Bluetooth transceiver that scans for devices broadcasting a Bluetooth identity. An application executing on the service electronic device may configure the service electronic device to be discoverable by Bluetooth devices. Further, the application may configure the identity associated with the service electronic device such that the vending machine is able to analyze the identity to determine that the identity corresponds to a service electronic device. In this example, when the Bluetooth transceiver of the vending machine detects a Bluetooth device that has an identity indicative of the service electronic device, the vending machine may determine that the service electronic device is within the threshold distance. In some implementations, to prevent other devices spoofing a service electronic device, a PIN or other code is exchanged to ensure that the identity actually corresponds to a service electronic device.
• Atblock424, the vending machine analyzes an inventory database (such as theinventory databases232 and332 ofFIGS. 2 and 3, respectively) to generate a list of items having a status indicative of being unsellable. For example, the status may indicate that the item is expired, recalled, been exposed to a temperature outside of a suitable range for too long, etc. Atblock426, the vending machine generates a command to vend each item in the list of unsellable items. As described with respect toFIG. 2, the command may be formatted to instruct one or more vending actuators to dispense the item stored at a particular slot that corresponds to the item within the list of unsellable items.
• To prevent the automatic unloading of products from impacting the customer experience, atblock428 the vending machine determines that no customers are utilizing the vending machine. In some embodiments, the vending machine detects the expiration of a timer (e.g., thirty seconds, one minute, two minutes, five minutes, etc.) that begins when a customer activity session expires. According to aspects, the customer activity session expires when a customer completes a purchase or if a session timeout occurs. Additionally or alternatively, the vending machine may detect the presence of a customer using a camera. Accordingly, the vending machine may analyze image data generated by the camera to determine that no customers are standing in front of the vending machine. In response to determining that no customers are utilizing the vending machine, atblock430 the vending machine issues the commands generated atblock426. As a result, the vending machine automatically begins vending the unsellable items to reduce vending machine downtime.
Item Lockout
• FIG. 7 illustrates anexample method440 for implementing the remote item lockout functionality described herein. Themethod440 is implemented by a vending machine, such as thevending machines115 and215 ofFIGS. 1 and 2, respectively or Fridge Y ofFIG. 3.
• Themethod440 begins when the vending machine detects a lockout request received via the one or more transceivers, the lockout request indicating an item type. The item type may be a SKU or an item category (e.g. salad). In one scenario, the lockout request is an indication that the item type has been recalled. For example, a management server (such as themanagement server125 ofFIG. 1) may receive an indication from a supplier or government agency that the item type has been recalled. Accordingly, the management server may transmit the lockout request to prevent the vending machine from distributing recalled items.
• In another scenario, the lockout request is indicative of the item type being exposed to temperatures outside of a suitable range of temperatures for more than a threshold duration. As described above, each item or item type may correspond to a suitable range of temperatures. Accordingly, database records associated with the item or item type may include an indication of the suitable range of temperatures. In this scenario, the vending machine includes a temperature sensor that monitors the temperature within the vending machine. The vending machine may then periodically report the temperature to the management server. The management server may then compare the reported temperature from the vending machine to the suitable range in the item type records. If the management system determines that the temperature of the vending machine has been outside of a suitable range of temperatures for a threshold duration, the management server may generate a lockout request for those item types.
• Atblock444, the vending machine queries an inventory database (such as theinventory databases232 and332 ofFIGS. 2 and 3, respectively) to identify items associated with the item type. Atblock446, the vending machine changes a status indication in a record corresponding to the items to indicate that the items are locked out. In some embodiments, the vending machine changes the record for each individual item. In other embodiments, the item status is maintained as parameter associated with the item type. In these embodiments, changing the status of the item type record propagates the change to each item. In any event, changing the status of the item prevents the item from appearing in a list of available items. For example, the management server may periodically request a list of available items to facilitate the above-described reserve and pay functionality. As another example, when a customer interacts with a display unit of the vending machine, the locked out items do not appear in a user interface indicating available items. Accordingly, customers are unable to purchase locked out items.
