Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric adhesive patches are used to monitor physiological signals, then signal measurement capability is achieved, but reliability deteriorates during exercise due to detachment
Solution Approach 1:
The invention removes the adhesive component entirely from the system. Instead of using adhesive patches that detach during exercise, the patent employs ring electrodes integrated directly into the garment structure, eliminating the source of instability while maintaining signal measurement capability
Solution Approach 2:
The ring electrodes are merged with the garment structure itself, creating an integrated system where the electrode, conductor, and garment become a unified whole. This integration ensures the electrodes remain in stable contact with the skin during physical activity without relying on separate adhesive components
2Ease of operation
If electric adhesive patches are integrated into garments, then ease of operation is improved, but reliability worsens due to folder over and detachment
Solution Approach 1:
The invention uses ring-shaped (circular/curved) electrodes instead of flat patches. This curved geometry allows the electrodes to conform to the cylindrical shape of body limbs, maintaining stable skin contact during movement while remaining integrated into the garment structure
Solution Approach 2:
The ring electrodes are constructed as flexible, thin structures that can bend and conform to body contours. This flexibility allows the electrodes to maintain intimate contact with the skin during exercise while being seamlessly integrated into the garment, eliminating both detachment and folding issues
3Measurement precision
If electric adhesive patches are used, then physiological signal sensing is achieved, but measurement precision deteriorates due to inconsistent contact
Solution Approach 1:
The ring geometry provides consistent circumferential contact with the body, ensuring uniform pressure and stable electrical contact throughout the measurement period. This curved configuration maintains reliable signal acquisition during dynamic movement better than flat patches
