Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple independent cables are used to connect each myoelectric electrode to a controller, then electrical connection between electrodes and controller is ensured, but the complexity of attaching electrodes and managing cables increases significantly
Solution Approach 1:
Multiple independent cable connections are merged into a single integrated flexible printed circuit board that electrically connects multiple myoelectric electrodes to the controller simultaneously, reducing the number of separate connection components and simplifying the overall attachment process while maintaining reliable electrical connectivity
2Ease of operation
If multiple independent cables are used to connect each myoelectric electrode, then individual electrode connections are established, but the number of cables and connection points increases making the system cumbersome
Solution Approach 1:
Multiple separate cables are consolidated into a single flexible printed circuit board that provides electrical connections to multiple electrodes through integrated conductive traces, thereby reducing the total quantity of cable components from multiple separate cables to one unified connection structure
Solution Approach 2:
The flexible printed circuit board serves multiple functions simultaneously: it acts as a structural support for electrodes, provides electrical connectivity between electrodes and controller, and enables flexible positioning across multiple attachment points, replacing what would otherwise require multiple specialized cable components
