The invention relates to a smart locker system and a method of controlling the same.
The online purchase of household goods has seen explosive growth in the past several years. With the recent announcement that Whole Foods Market has been acquired by Amazon, industry analysts predict tremendous changes are in store for traditional grocery chain businesses, which have remained mostly unchanged for more than a century. In fact, more than 80% of Americans have bought products online in the past month, and this trend is continuing to build momentum. Grocery items will likely follow the same trend line, however it will not be without a fairly substantial change in the manner that home delivery takes place.
Along with the rise in confidence of online ordering comes a negative side-effect, namely, a steady rise in theft of delivered products from the doorsteps of homes. This has resulted in staggering growth of front-door camera sales for products like Ring and Nest Cams, which enable homeowners to monitor activities at the front of their homes.
However, there is a critical deficiency in the delivery chain relative to how cold and frozen grocery goods are delivered and received into homes. In order to take advantage of the convenience of home delivery of standard groceries, the purchasing consumer must schedule a window of time to receive the groceries, and hope that schedule changes or late deliveries don't occur. What should be a convenience often becomes a hindrance to consumers, as the delivery method eliminates any flexibility to leave the home during the delivery window.
Certainly, if the online purchase of perishable goods is to continue to expand, a better model is needed to order, deliver, and receive these everyday items.

In some embodiments, the compartments 102-1 to 102-n may have electric doors, without handles, that open and close/lock based on proximity to an authorized user (e.g., a home owner or an authorized delivery person) and/or based on wireless commands received from an external device (e.g., a smart phone, tablet, or laptop). In some embodiments, the smart locker system 100 has a keypad 106 that acts as a backup entry device, which opens one or more of the compartments 102-1 to 102n when an authorized code is entered. In some examples, each package may have its own code (e.g., a temporary or one-time code), which, when entered, allows the smart locker system 100 to identify the appropriate compartment 102 to open. For example, a package containing perishable goods may include a code that, when entered, opens the first or second compartments 102-1 and 102-2.
As will be recognized by a person of ordinary skill, the authentication functionality of the keypad 106 may be replaced by, or supplemented by, an iris scanner, a fingerprint reader, and/or any other suitable authentication mechanism.
In some embodiments, solar panels 108 that are mounted on one or more surfaces (e.g., the top surface) of the smart locker system 100 provide electrical power to the system. For example, the solar panels 108 may charge a backup/auxiliary battery within the smart locker system 100.
According to some embodiments, to protect delivered packages from the elements, each of the compartments 102-1 to 102-n may be sealed or otherwise configured to prevent or substantially prevent intrusion of moisture and dust and is protected against corrosion. For example, the compartments 102 may be IP69K-rated.
As shown in

The power manager 112 may receive electrical power from an external source EXT, such as a power line (e.g., a 110 V DC line) connected to the electrical grid of a home, outside of which the smart locker system 100 may be installed. The power manager 112 may have a battery 116 that acts as a backup or auxiliary source of power for the smart locker system 100, when the power received from the external source EXT is either insufficient or not present. However, embodiments of the invention are not limited thereto, and the battery 116 may operate as the primary source of power to the smart locker system 100 and the external source EXT may serve to recharge the battery 116. In some examples, the smart locker system 100 may receive power from solar panels 108 that may be installed on the top and/or side panel(s) of the smart locker system 100. The solar panels 108 may be used to charge the battery 116 during daytime. The power manager 112 may be capable of self-diagnosis (under the direction of the controller 110) to detect any circuit overloads and/or excessive heat generation. If such conditions are detected, the power manager 112 may transmit a corresponding fault signal to the controller 110, which may in turn alert a user (e.g., the homeowner) and/or a monitoring server external to the smart locker system 100 that a power fault condition has occurred.
In some embodiments, the cooling system 114 removes heat from the one or more compartments 102 via one or more cooling lines and control valves, which may be opened or closed based on control signals received from the controller 110 or the cooling system 114 itself. The cooling system 114 may be a traditional refrigeration system having a compressor, a heat exchanger (e.g., a condenser), an expansion valve, and an evaporator (e.g., and evaporation coil), or may be any other suitable cooling system 114, such as one relying on geothermal cooling.
According to some embodiments, each of the compartments 102-1 to 102-n includes one or more sensors 118, which may include a weight sensor (e.g., a pressure sensor), a temperature sensor, and/or the like. For example, when a package is placed in a compartment 102, the weight sensor detects a positive pressure change and reports it to the controller 110. If the positive pressure change is above a preset threshold, the controller 110 determines that an object has been placed in the corresponding compartment 102. Upon such determination, if the compartment is a cooling chamber (e.g., is 102-1 or 102-2), the controller may signal the cooling system 114 to cool the chamber down to the appropriate temperature. The temperature reading from the temperature sensor inside the cooling chamber may be used to regulate the chamber's temperature. Similarly, when a package is removed from a compartment 102, the weight sensor detects a negative pressure change and reports it to the controller 110. If the negative pressure change is below a preset threshold, the controller 110 determines that an object has been removed from the corresponding compartment 102. Upon such determination, if the compartment is a cooling chamber (e.g., is 102-1 or 102-2), the controller 110 may signal the cooling system 114 to stop cooling the chamber, in order to conserve energy.
In some embodiments, the smart locker system 100 includes a transceiver 120 to enable internet connectivity. The transceiver 120 may include a hard-wired cable transceiver, a wireless transceiver (e.g., to connect via WiFi), and/or an onboard cellular chip to ensure constant connectivity to the internet. When an order for a product is placed online and a delivery schedule is set, an online server may communicate the expected delivery period to the smart locker system 100. If the delivery is for a frozen or refrigerated item, the controller 110 may prompt the cooling system 114 to cool the corresponding compartment(s) (e.g., 102-1 and/or 102-2) to a suitable temperature in advance of scheduled delivery. Once the package is removed from the corresponding compartment(s), the controller 110 may prompt the cooling system to stop cooling the compartment(s). This ensures that the delivered perishable good is maintained at the proper temperature at all times, while also conserving energy when the cooling chambers are not in use.
According to some embodiments, each compartment 102 includes an electronic locking mechanism 122 that allows the controller 110 to control the opened/closed/locked state of the compartment 102. For example, the controller 110 may unlock the locking mechanism(s) 122 in response to a command received from a user's smart device (e.g., a smart phone) that may be connected to the smart locking device via an application (or an “app”), or may automatically unlock the appropriate compartment(s) in response to detection of a connected device within a proximate range (e.g., within about 3 feet or about 6 feet) of the smart locker system 100. Thus, when the controller 110 determines that an owner of the locker system 100 or an authorized delivery person, who carries the connected device, is approaching the smart locker system 100, the controller 110 automatically opens the appropriate compartment 102 to allow for delivery or collection of a package. The controller 110 may control the locking mechanisms 122-1 to 122-n to maintain the compartments 102-1 to 102-n in a locked state at all other times. Proximity detection may be facilitated by a proximity sensor 124 that may installed on a panel or a compartment door of the smart locker system 100.
The smart locker system 100 may be capable of providing automatic notifications to the owner via a connected application installed on the smart device of the owner (which may, e.g., be an Android or iOS device). For example, the smart locker system 100 may alert the user when a shipment has been received, and/or when there is inadequate power (e.g., inadequate charge at the battery 116) to maintain critical temperatures in the compartments 102. Further, the application installed on the user device may allow the user to monitor the power utilization of the smart locker system 100, to view shipment time forecasts, and be alerted of delayed shipments and failed delivery attempts due to the package size exceeding the available storage space.
In some examples, the smart locker system 100 may have available to it, a host of security features, such as internal infrared motion detection sensors, external lighting to assist with evening deliveries, a one-touch “panic” button, which sounds an audible alarm, and a camera 126 to capture a photo or a video segment every time one of the compartments 102 is opened. The captures images/videos may be stored locally and/or on a remote server (e.g., a cloud server), and may be downloadable/viewable on the smart device of the user.
Accordingly, by utilizing a combination of several different emerging technologies, including internet of things (IoT), cloud-computing, order scheduling, monitoring, and delivery tracking, as well as product-level technologies like precision smart-scales and a plethora of sensors, online ordering can pave the way for a new type of connected mailbox, which will in time replace what we have used to collect and send mail since the dawn of industrialization.
