Robot Picking With Tagged Circulation Boxes for Multi-Order Fulfillment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing warehouse order picking methods in electronic commerce environments face challenges of low delivery efficiency and unadaptability to high-frequency, small-size order picking requirements, leading to complex logistics processes and increased costs.
Innovation Solution
A robot-based warehouse order picking method that binds a circulation box and a robot using identity information, including tags and goods placement marks, to directly connect picking and packaging regions, eliminating the need for an additional sorting step, and uses an interaction terminal to instruct pickers on goods placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If multiple orders are combined into a large goods picking task and assigned to a single picker, then the picking task can be completed in a single round trip, but the logistics process becomes complex and sorting efficiency decreases
Solution Approach 1:
The patent divides the circulation box into multiple circulation positions, each corresponding to a specific order. Each position has its own tag and goods placement mark, allowing parallel processing of multiple orders without requiring complex sorting operations after picking. This segmentation enables the picker to complete multiple orders in one round trip while maintaining process simplicity.
Solution Approach 2:
The patent introduces tags and goods placement marks as intermediary elements that establish correspondence between circulation positions and orders. These intermediaries enable automatic order identification and goods placement guidance, eliminating the need for manual sorting and reducing logistics process complexity while maintaining efficient picking operations.
2Manufacturing precision
If a sorting region is added to split the large goods picking task into multiple orders, then order accuracy improves, but the logistics process becomes more complex and efficiency decreases
Solution Approach 1:
The patent pre-establishes the correspondence between circulation positions and orders through tags and goods placement marks before the picking process begins. This preliminary configuration ensures that goods are placed in the correct position during picking, eliminating the need for subsequent sorting operations and maintaining high logistics efficiency while ensuring order accuracy.
Solution Approach 2:
The circulation box with its tagged positions and placement marks serves as a self-organizing system that automatically guides goods placement without requiring external sorting intervention. Each circulation position self-identifies its associated order through tags, and the placement marks guide pickers to deposit goods in the correct location, achieving both accuracy and efficiency.
3Device complexity
If traditional picking methods are used for high-frequency small-size goods, then the logistics process remains simple, but delivery efficiency is low and the system is unadaptable to e-commerce requirements
Solution Approach 1:
The circulation box serves multiple functions: it acts as a container for goods, an identification system through tags, a placement guide through marks, and an order organization structure. This multi-functionality enables the system to handle high-frequency small-size goods efficiently while maintaining process simplicity, making it adaptable to e-commerce requirements without adding complex logistics procedures.
