Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the first transfer unit transfers electrodes from the electrode magazine to the alignment table, then the electrode transfer process is completed, but multi-sheet electrodes may be transferred simultaneously causing waste and reduced yield
Solution Approach 1:
The system performs preliminary detection of multi-sheet electrodes before the transfer process completes. The multi-sheet detection unit identifies stacked electrodes in advance, allowing the controller to adjust adsorption forces during the transfer process to separate and correctly position each electrode individually, preventing waste while maintaining transfer efficiency
Solution Approach 2:
The system uses feedback from the multi-sheet detection unit to dynamically adjust the adsorption force of the first transfer unit. When multi-sheet electrodes are detected, the controller increases the adsorption force to separate and correctly position each electrode, ensuring accurate placement while preventing simultaneous transfer of multiple electrodes that would cause waste
2Manufacturing precision
If the adsorption force of the first transfer unit is increased to prevent multi-sheet transfer, then electrode separation is improved, but the complexity of controlling the transfer process increases
Solution Approach 1:
The controller receives feedback from the multi-sheet detection unit and automatically adjusts the adsorption force of the first transfer unit accordingly. This closed-loop control system simplifies the overall process by using sensor data to make real-time adjustments, eliminating the need for complex manual control while maintaining high placement accuracy
Solution Approach 2:
The system replaces complex mechanical control mechanisms with a sensor-based detection and electronic control system. The multi-sheet detection unit and controller work together to automatically adjust adsorption forces, substituting mechanical complexity with electronic sensing and control that achieves the same precision more efficiently
