Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional cutting device with a fixed cutting structure is used, then the cutting process is simple, but defective electrodes cannot be separately removed from good electrodes
Solution Approach 1:
The cutting device employs a movable cutting member that can dynamically adjust its position along the electrode base material travel path. The cutting member transitions between a first position for cutting good electrodes and a second position for cutting defective electrodes, enabling flexible defect removal without requiring multiple fixed cutting stations.
Solution Approach 2:
The cutting device separates the cutting function into distinct operational modes: a first cutting mode for good electrodes at a first discharge position, and a second cutting mode for defective electrodes at a second discharge position. This segmentation allows independent handling and discharge of good and defective electrodes through separate discharge members.
2Reliability
If the cutting member is fixed at one position, then the device structure is simple, but both good and defective electrodes are discharged together
Solution Approach 1:
The discharge mechanism is segmented into a first discharge member for good electrodes and a second discharge member for defective electrodes. These discharge members are positioned at different locations along the travel path and are independently controllable, allowing separate discharge of good and defective electrodes to prevent mixing.
Solution Approach 2:
The discharge members are dynamically controlled to be active at different times and positions. The first discharge member operates when the cutting member is at the first position, while the second discharge member operates when the cutting member is at the second position, ensuring temporal and spatial separation of electrode discharge.
3Reliability
If defect sensing is performed before cutting, then defective portions can be detected, but the defective electrodes cannot be removed during the cutting process
Solution Approach 1:
The defect sensing part performs preliminary detection of defective portions on the electrode base material before the cutting process. Based on the detection results, the control part pre-determines the cutting position and mode, allowing the cutting member to be positioned at the appropriate first or second position before cutting occurs, enabling immediate defect removal without additional processing steps.
Solution Approach 2:
The system implements a feedback loop where the defect sensing part continuously monitors the electrode base material, and the control part adjusts the cutting member position and discharge member activation based on real-time defect detection signals. This closed-loop control enables dynamic adaptation of the cutting process to remove defective electrodes while maintaining high processing efficiency.
