Worker-Guided Autonomous Carts for Flexible Warehouse Picking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Warehouses face challenges in improving operating productivity due to limitations in existing automation systems, including dependency on labor, constraints in space, time, and cost, as well as seasonal labor access issues.
Innovation Solution
A warehouse automation system featuring enhanced carts with controllers that associate with workers, providing navigation, task assignment, and real-time feedback through on-screen and off-screen interfaces, sensors, and robotic arms to streamline product movement and processing, reducing labor dependency and increasing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual labor is used for warehouse operations, then labor flexibility is maintained, but productivity and efficiency are limited
Solution Approach 1:
The cart system operates autonomously without requiring manual pushing or pulling. The cart self-propels through the warehouse, automatically navigates to locations, and performs tasks independently, eliminating the need for human physical effort while maintaining operational flexibility
Solution Approach 2:
Manual mechanical labor is replaced with an automated electromechanical cart system. The cart uses electric motors for propulsion, electronic sensors for navigation, and automated interfaces for task execution, substituting human physical work with automated mechanical and electronic systems
2Productivity
If traditional automation systems are installed, then labor dependency is reduced, but installation time and cost increase
Solution Approach 1:
The warehouse automation is divided into independent modular cart units rather than a single large fixed system. Each cart operates independently and can be deployed separately, allowing for phased implementation that reduces installation time and initial cost while maintaining scalability
Solution Approach 2:
The system transitions from static fixed automation infrastructure to dynamic mobile cart units. The carts can be moved, repositioned, and reassigned based on changing warehouse needs, providing flexibility that reduces the time and cost of reconfiguration compared to fixed automation systems
3Productivity
If fixed automation systems are implemented, then productivity improves, but adaptability to changes decreases
Solution Approach 1:
The system uses mobile carts that can dynamically change their positions, routes, and assigned tasks based on real-time warehouse conditions. This dynamic capability allows the system to adapt to changing product mixes, customer demands, and operational priorities while maintaining high productivity
Solution Approach 2:
The cart system is designed to perform multiple functions including transporting products, delivering orders, retrieving inventory, and supporting various warehouse operations. This multi-functionality allows a single system to adapt to diverse operational requirements and changing business needs

AI summary
A warehouse automation system adapted to improve warehouse operating productivity includes a plurality of carts for transporting products within a warehouse and a controller. The controller is adapted to associate a first one of the plurality of carts with a first person and to control the first cart to lead the first person around the warehouse. According to one advantage, the time the first person spends restocking, picking, counting, sorting, moving, and packing product into customer orders and shipments, for example, is reduced.
