Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing workload and inefficiency in processing article orders in physical distribution delivery bases, particularly in automated warehouses, due to the need for manual handling of multiple article types and varying delivery requirements.
Innovation Solution
An article order processing system that selects between single and total picking methods based on article orders, utilizing autonomous robots and guided vehicles to optimize article processing, and determines priority processing to enhance efficiency and completion speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual handling of multiple article types is used in physical distribution delivery bases, then flexibility in processing various article orders is maintained, but workload increases and processing efficiency decreases
Solution Approach 1:
The system enables self-service through automated robots that independently perform picking tasks. The autonomous mobile robot navigates to storage locations, retrieves articles, and transports them to picking stations without human intervention for the actual picking operations, thereby reducing manual workload while maintaining processing efficiency
Solution Approach 2:
Manual mechanical handling is replaced with automated robotic systems. The autonomous mobile robot uses sensors, navigation algorithms, and robotic manipulation mechanisms to perform tasks previously done manually, such as locating articles, retrieving them from shelves, and transporting them to picking stations
2Productivity
If automated robots are introduced to reduce manual workload, then processing efficiency improves, but system complexity increases
Solution Approach 1:
The autonomous mobile robot is designed as a universal platform that can handle multiple article types and perform various operations including navigation, article retrieval, and transport. This multi-functional design consolidates what would otherwise require multiple specialized systems into a single versatile robot, managing complexity while improving efficiency
Solution Approach 2:
The control server acts as an intermediary between the autonomous mobile robot and the overall system management. It coordinates robot movements, manages task assignments, processes sensor data, and communicates with the warehouse management system, thereby simplifying the overall system architecture by centralizing control functions
3Adaptability or versatility
If single picking method is used for all article orders, then processing speed is maintained, but adaptability to different delivery requirements is reduced
Solution Approach 1:
The system dynamically selects between single picking method and total picking method based on real-time conditions such as article order characteristics, robot availability, and warehouse state. This dynamic adaptation allows the system to optimize processing time for each specific situation while maintaining versatility across different delivery requirements
