Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the heart rate strap uses highly elastic base materials to ensure close contact with the skin, then the electrocardiogram signal acquisition is improved, but the wearing comfort deteriorates
Solution Approach 1:
The patent introduces a conductive layer as an intermediary between the skin and the electrocardiogram electrodes. This conductive layer is integrated into the garment structure, allowing the electrodes to acquire electrical signals without requiring highly elastic materials that compromise comfort. The conductive layer mediates the contact between the monitoring device and the body, maintaining signal quality while improving wearing experience.
2Measurement precision
If the heart rate strap requires removing or lifting other garments to ensure close skin contact, then the electrocardiogram signal acquisition is improved, but the privacy requirement increases
Solution Approach 1:
The patent merges the electrocardiogram electrodes with the garment structure itself, integrating them into the clothing that the user wears normally. This combination allows the monitoring function to be incorporated into everyday attire, eliminating the need to remove or lift other garments. The electrodes are positioned within the garment to maintain close proximity to the skin while allowing the user to wear the garment as usual, thus preserving privacy and expanding wearing scenarios.
3Ease of operation
If the heart rate strap contacts the garment during exercise, then static electricity is generated, but this static electricity interferes with the electrocardiogram signal
Solution Approach 1:
The patent addresses the static electricity issue by using conductive materials that can dissipate static charges rather than accumulate them. The conductive layer and electrodes are designed to provide a pathway for static electricity to be safely discharged, converting the potentially harmful static buildup into a controlled electrical flow that does not interfere with the electrocardiogram signal acquisition.
