The disclosure relates generally to temperature-controlled environments.
Cold chain transport for food, drug or any products that need temperature control for delivery currently is done with tri-temperature or refrigerated trucks and vans upfitted with compressor based systems that cool or freeze the entire sectioned area of a truck and must be run constantly to maintain temperature inside the truck weather the truck has one gallon of mike or a pint of ice cream you need to cool or freeze the entire space. Compressor based refer trucks and tri temp trucks or van must be penetrated from the outside to get the cooling platform of a compressor-based system inside the truck or van voiding the warranty of the van or truck. In addition, to run try temperature trucks you must use dividers between the temperature zones to maintain temperature. The separation of space requires you to separate orders that have goods in two or more zones. Compressor based systems pull too much power for the system to be placed in or on a fully electric vehicle without degrading the range of the vehicle significantly. Improved systems and methods for thermal management are needed.
Systems and methods for temperature driven dynamic order sequencing in order fulfillment are provided herein. In some embodiments, a method of controlling two or more actively cooled totes includes: determining a first ordering of the two or more actively cooled totes; determining that an alert condition occurred for an alerted tote of the two or more actively cooled totes; and determining a second ordering of the two or more actively cooled totes based on the alert condition where the alerted tote is in a different position in the ordering than in the first ordering.
Dynamic tote arrangement can therefore ensure that customer orders are sequences appropriately based on the temperature warnings the totes provide, minimizing spoilage in the tote queue process.
Order fulfillment software creates batches of sequenced orders to be fulfilled based on order and/or product attribute data. These orders are then fulfilled following a predetermined sequence, arriving at a packing station manually or via automation. An enhancement to the order batching and sequencing processes (the reason for this IP disclosure) would allow for the order fulfillment software to dynamically update the batch content and sequence of orders, and associated products within the orders, containing temperature sensitive attributes, based on the temperature communication provided by the actively cooled totes to the order management software to mitigate food safety concerns and potential product spoilage.
This process enhancement has immense value in eCommerce applications where temperature-sensitive product such as, but not limited to, frozen goods, fresh produce or some pharmaceuticals need to remain in temperature-specific custody to guarantee safety, product integrity, and high customer satisfaction.
In some embodiments, APIs include temperature warning data messages to the host software so that customers can determine how they want to manage the exceptions within their software, depending on the hardware portion of solution chosen for their end-customer's application. The functionality of this enhancement works with a variety of manual and automated fulfillment platforms including but not limited to: operators manually fulfilling with handheld technologies, convey and sort applications, and robotic applications.
Those skilled in the art will appreciate the scope of the present disclosure and realize additional aspects thereof after reading the following detailed description of the preferred embodiments in association with the accompanying drawing figures.
The accompanying drawing figures incorporated in and forming a part of this specification illustrate several aspects of the disclosure, and together with the description serve to explain the principles of the disclosure.
The embodiments set forth below represent the necessary information to enable those skilled in the art to practice the embodiments and illustrate the best mode of practicing the embodiments. Upon reading the following description in light of the accompanying drawing figures, those skilled in the art will understand the concepts of the disclosure and will recognize applications of these concepts not particularly addressed herein. It should be understood that these concepts and applications fall within the scope of the disclosure and the accompanying claims.
Cold chain transport for food, drug or any products that need temperature control for delivery currently is done with tri temperature or refer trucks and vans upfitted with compressor based systems that cool or freeze the entire sectioned area of a truck and must be run constantly to maintain temperature inside the truck weather the truck has one gallon of mike or a pint of ice cream you need to cool or freeze the entire space.

In addition, to run try temperature trucks you must use dividers between the temperature zones to maintain temperature. The separation of space requires you to separate orders that have goods in two or more zones. Compressor based systems pull too much power for the system to be placed in or on a fully electric vehicle without degrading the range of the vehicle significantly.
The alternative to compressor-based cooling is to use passive cooling products like gel packs or dry ice to cool products packaged inside of boxes or totes, this is a very costly process in both labor and materials. Both the use of compressor and passive cooling and freezing is very damaging to the environment because of the refrigerant, the materials or the continuous running of the truck and compressor to maintain temperature.
Upfitting the transport vehicle with thermal electric active cooling and freezing totes with on demand cooling and sustainable refrigerants that require no penetration to the van/truck and minimal impact to range on electric vehicles.
The ability to use mobile and transportable containers using thermal electric cooling to be placed in transportation vehicles (e.g., van, box truck, car, train, plane, boat) would include the ability to use the same containers to transport between physical centers like MFC, stores and the mobile vehicle all the way to the house, apartment, or place of business. This would also include all IOT capabilities for command, control, and monitoring of the temperature of each container is transport. In some embodiments, this is used in an EV or combustion engine vehicles and using the power source of the vehicle and or a battery pack that would be recharged by the vehicle to power our totes.
Last mile delivery of food requires temperature-controlled transport of perishable food items using transit vans or similar vehicles. For temperature control, refrigerated or freezer totes can be used which are installed in the van (e.g., a cargo van) or a box truck.
These totes use an active heat pump to pull heat from an enclosed chamber and reject it to the surrounding ambient environment. When this is in an enclosed location such as a delivery van, the hot air can be removed from the van to improve operational performance of the totes.
These totes require power while in transit maintain food safety requirements for perishable consumption. The electrical system needed to reach (and/or maintain) the correct temperature should meet certain expectations for the operation of the totes.

While the embodiments described herein use AMR's (Automated guided vehicle) as the hardware means of fulfillment, embodiments can be executed by other hardware solutions.
In this scenario, WES has one of four options:
In some embodiments, the preceding totes would move out of the way, creating a bypass or some other method. The displaced totes would fall back in the prior sequence based on the earlier order priority, but behind the expedited tote D. Shortly thereafter, tote C gives WES the same warning that it needs to be dispositioned based on the above options WES can make.
Totes A and B are displaced, creating a bypass so tote C can move up in priority.
Dynamic tote arrangement can therefore ensure that customer orders are sequences appropriately based on the temperature warnings the totes provide WES, minimizing spoilage in the tote queue process.
Order fulfillment software creates batches of sequenced orders to be fulfilled based on order and/or product attribute data. These orders are then fulfilled following a predetermined sequence, arriving at a packing station manually or via automation.
