Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual dismantling is performed by experts, then precision and safety are improved, but productivity is reduced and labor costs increase
Solution Approach 1:
The system uses sensors to automatically detect battery components and their positions, eliminating the need for manual inspection by experts. The robot autonomously identifies connectors, fastening members, and battery components through sensing data, achieving both precision and high-speed automated processing
Solution Approach 2:
The patent replaces manual mechanical operations with an automated robot system that uses sensors for detection and robotic manipulators for dismantling actions. This substitution maintains precision through controlled mechanical movements while dramatically increasing processing speed and productivity
2Productivity
If automated robot system is implemented, then productivity is improved and labor costs are reduced, but device complexity increases
Solution Approach 1:
The robot system is designed with multi-functional capabilities, using the same robotic manipulator and sensor system for multiple tasks including detecting connectors, removing fastening members, and separating battery components. This universal approach increases productivity while managing device complexity through resource sharing
Solution Approach 2:
The control system acts as an intermediary between sensors and robotic manipulators, processing sensing data to identify component positions and generating control signals for precise dismantling operations. This intermediary layer manages system complexity by providing a centralized coordination point
3Measurement precision
If multiple sensors and robot apparatus are used for accurate battery diagnosis and dismantling, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The sensor system is designed to perform multiple detection functions using integrated sensor arrays that can identify connector positions, fastening member locations, and battery component boundaries simultaneously. This multi-functional sensing approach improves measurement precision across all components while managing system complexity through unified sensor architecture
