Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional bioelectrode with specialized placement requirements is used, then measurement precision can be maintained, but ease of operation deteriorates due to the need for specialized knowledge
Solution Approach 1:
The base material is segmented with notches that divide it into multiple regions, each potentially containing electrode parts. This segmentation allows the electrode to be flexibly configured for different measurement needs while maintaining ease of attachment, as users can attach the divided sections to different body locations without requiring complex placement knowledge.
Solution Approach 2:
The base material has an asymmetric spread-toward-the-bottom shape with notches positioned at specific locations rather than symmetrically. This asymmetric design creates distinct attachment orientations and positions, guiding users to attach the electrode correctly without requiring specialized knowledge, while still achieving reliable signal quality through optimized electrode placement.
2Reliability
If a secure attachment method is used, then reliability of signal transmission improves, but ease of operation worsens due to difficulty in detachment
Solution Approach 1:
The notched base material creates segmented attachment zones that can be independently secured to the body. Each segment can be attached and detached separately, allowing users to secure the electrode reliably while maintaining ease of removal by simply peeling off individual segments without complex detachment procedures.
3Measurement precision
If electrode parts are placed close together, then device complexity is reduced, but measurement precision deteriorates due to increased noise interference
Solution Approach 1:
The spread-toward-the-bottom shape with notches utilizes the two-dimensional plane of the base material more effectively, distributing electrode parts across different regions and orientations. This dimensional arrangement allows sufficient spacing between electrodes to minimize noise interference while maintaining a relatively simple overall device structure that can be attached to the body in a single operation.
