Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If electrodes having different areas are manufactured through different processes, then the manufacturing precision of each electrode type is maintained, but the productivity of electrode production is deteriorated
Solution Approach 1:
The initial electrode is divided into multiple middle-stage electrodes through cutting, where at least one middle-stage electrode has a different length from others. This segmentation allows different electrode areas to be obtained from a single initial electrode, improving productivity while maintaining manufacturing precision through controlled cutting processes.
Solution Approach 2:
The initial electrode is manufactured with a predetermined coating pattern where coating portions are spaced apart from each other. This preliminary action enables subsequent cutting to produce electrodes with different areas while maintaining consistent coating quality, resolving the contradiction between precision and productivity.
2Manufacturing precision
If multiple processes are used to manufacture electrodes having different areas, then the manufacturing precision of each electrode type is maintained, but the equipment and costs required for production increase
Solution Approach 1:
A single initial electrode manufacturing process produces electrodes that can be cut into multiple middle-stage electrodes with different lengths. This multi-functional approach allows one manufacturing line to serve multiple electrode type requirements, reducing equipment complexity and production costs while maintaining manufacturing precision through standardized cutting procedures.
