Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electrode sheet is moved repeatedly during manufacturing, then the electrode can be processed and cut, but the electrode sheet develops curls and may be damaged
Solution Approach 1:
The electrode transfer table is divided into multiple sheet seating portions (first sheet seating portion, second sheet seating portion, etc.) that can independently hold different electrode sheets. This segmentation allows multiple electrodes to be prepared simultaneously on different sections of the table, reducing the need to move single sheets repeatedly between processing stages.
Solution Approach 2:
The sheet seating portions act as intermediaries between the transport system and the cutting device. The electrode sheets are held on these seating portions during transport and cutting operations, providing a stable intermediate holding position that prevents curls and damage while enabling efficient material flow through the manufacturing process.
2Manufacturing precision
If the electrode sheet is moved to a cutting device separately, then cutting can be performed, but the work process becomes complicated
Solution Approach 1:
The cutting device is integrated with the electrode transfer table such that the table serves dual purposes: transporting electrode sheets and providing the cutting surface. The sheet seating portions are positioned on the transfer table, and the upper and lower blades can cut electrodes directly on the table without requiring separate transfer to another cutting device, thereby simplifying the overall work process while maintaining cutting precision.
3Productivity
If multiple electrode sheets are processed simultaneously, then productivity increases, but the device complexity increases
Solution Approach 1:
The electrode transfer table is designed with multiple sheet seating portions that can handle different electrode sheets simultaneously. The transport system moves the entire table with all seated sheets, and the cutting device can process multiple electrodes in one operation. This multi-functional design enables parallel processing of multiple electrodes without requiring separate dedicated devices for each sheet, thus increasing productivity while controlling system complexity.
