Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing warehouse sorting systems, such as those using conveyor belts and mezzanine levels, are inefficient, costly, and lack scalability to handle the increased demand from e-commerce.
Innovation Solution
The implementation of a system or network of movable robotic devices, including robotic drive sorters and robotic drive containers, that sort packages within a sortation center. These robotic devices communicate with a logistic management system to navigate and transfer packages efficiently, eliminating the need for traditional infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional conveyor belts and mezzanine levels are used for package sorting, then packages can be sorted into containers, but the system requires significant infrastructure costs and provides little scalability
Solution Approach 1:
The patent replaces static conveyor belts and fixed mezzanine structures with dynamic mobile robots that can autonomously navigate and reposition themselves. The robots use dynamic path planning and can adapt their routes based on real-time sortation demands, eliminating the need for fixed infrastructure while maintaining sorting functionality.
Solution Approach 2:
The patent substitutes the mechanical conveyor belt system with autonomous mobile robots equipped with sensors and navigation systems. Instead of packages moving along fixed mechanical conveyors, robots autonomously transport packages to their destination containers, replacing heavy mechanical infrastructure with flexible robotic systems.
2Productivity
If traditional conveyor belts and mezzanine levels are used for package sorting, then packages can be sorted into containers, but the system is often inefficient
Solution Approach 1:
The patent implements preliminary path planning where robots calculate optimal routes to containers before transporting packages. The system pre-processes sortation data to determine destination containers in advance, allowing robots to efficiently plan their paths and minimize travel time without waiting for packages to reach conveyor transfer points.
Solution Approach 2:
The mobile robots are self-autonomous, navigating independently to containers and performing sortation without human intervention or fixed infrastructure. Each robot autonomously determines its path, transports packages, and returns for additional sortation tasks, creating a self-service system that eliminates inefficiencies associated with fixed conveyor transfer points.
3Productivity
If traditional conveyor belts and mezzanine levels are used for package sorting, then packages can be sorted into containers, but the system provides little to no scalability
Solution Approach 1:
The patent divides the sortation system into independent modular robot units rather than a single integrated conveyor system. Each robot operates independently, allowing the system to scale by simply adding or removing robot units based on demand. This segmentation enables flexible capacity adjustment without requiring extensive infrastructure modifications.
Solution Approach 2:
The mobile robots are designed with universal functionality to handle various package types and navigate to multiple container destinations. Each robot can service any container within its operational area, providing multi-functionality that allows the system to scale efficiently by deploying additional identical units rather than requiring specialized infrastructure for each sorting location.

AI summary
A system receives a first indication associated with a first device picking up a package and transmits a first instruction to the first device to travel to a location associated with transferring the package to a second device. The system may transmit a second instruction to the second device to travel to the location to receive the package from the first device. The system receives a second indication associated with the package being transferred from the first device to the second device at the location. One or more third devices may meet at the location to transfer packages to the second device. In some instances, the location may be determined based at least in part on a current location of the first device and/or a current location of the second device.
