Robot Container Handoff for Ergonomic Warehouse Item Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robotic warehouse systems face challenges in scalability and efficiency, particularly when transitioning items between containers, as they are designed for complete automation, limiting throughput and requiring manual intervention for higher volumes.
Innovation Solution
A hybrid system combining robotic pre-staging and human interaction, where robots position containers optimally for efficient picking, using mechanisms like suction cups, ramps, and elevators to facilitate ergonomic and scalable item transfer between containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a completely automated robotic distribution system is used, then automation level is improved, but scalability and throughput flexibility deteriorate
Solution Approach 1:
The system dynamically adjusts the level of automation based on throughput requirements. Robots can operate in fully automated mode for standard operations but can be reconfigured to work alongside human workers when higher throughput is needed, allowing the automation level to be flexible rather than fixed
Solution Approach 2:
The distribution system is segmented into independent robotic units that can operate autonomously or be grouped to work with human workers. This segmentation allows the system to scale by adding individual robot modules rather than requiring complete system reconfiguration
2Stability of the object's composition
If robots are positioned in fixed locations for automated item transfer, then system stability is improved, but ergonomic efficiency and accessibility deteriorate
Solution Approach 1:
The robotic system incorporates movable platforms and adjustable positioning mechanisms that allow robots to dynamically change their location and height. This enables the system to maintain stability during operations while improving ergonomic accessibility when human workers need to transfer items
Solution Approach 2:
The system uses elevation-adjustable platforms to bring robotic containers to the same height level as human workers, eliminating the need for workers to lift or reach awkwardly. This creates an equipotential working environment that improves ergonomic efficiency while maintaining system stability
3Reliability
If maximum throughput is fixed in the system design, then system reliability is improved, but scalability to higher throughput deteriorates
Solution Approach 1:
The system is designed with dynamic scalability, allowing the addition of more robotic units or human-robot collaborative teams as throughput requirements increase. The modular architecture maintains system reliability by allowing incremental expansion rather than requiring complete system redesign
Solution Approach 2:
The system is pre-configured with modular components and standardized interfaces that facilitate easy expansion. When higher throughput is needed, additional robotic units can be quickly integrated without extensive reconfiguration, enabling scalable growth while maintaining reliability

Implementation Method 1
positioning a source container under a suction robot... the suction robot having a flexible suction end having a variable suction component that can cause suction to occur within the suction end upon contact with an item
Data Source
AI summary
A method is disclosed for enabling a user to move items from one container to another. The method includes identifying a location of a user who will transfer items from a first container, attached to a first robot, to a second container, attached to a second robot, positioning the first container at a first position near the location of the user and positioning the second container via movement of the second robot at a second position near the location of the user. The method includes providing instructions to the user regarding how many items to move from the first container to the second container, receiving at least one item in the second container from the user and moving the second container from the second position to a destination position for the at least one item.
