Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the heart rate strap uses highly elastic base materials to ensure close contact with 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 be in close contact with the skin through the conductive layer rather than requiring direct skin contact with rigid electrodes. The conductive layer acts as a mediator that maintains both signal quality and wearing comfort.
2Measurement precision
If the heart rate strap requires removing or lifting other garments to ensure close contact with skin, then the electrocardiogram signal acquisition is improved, but the privacy requirement increases
Solution Approach 1:
The patent merges the electrocardiogram monitoring function with the garment itself by integrating conductive layers and electrodes directly into the fabric structure. This combination allows the garment to serve dual purposes: as clothing and as a medical monitoring device, eliminating the need to remove or lift the garment for signal acquisition while maintaining privacy.
3Ease of operation
If the heart rate strap contacts with garment to generate static electricity, then the wearing comfort is maintained, but the electrocardiogram signal accuracy deteriorates due to interference
Solution Approach 1:
The patent converts the harmful static electricity effect into a beneficial one by using conductive materials that can safely dissipate static charges. The conductive layer, while allowing close contact with the skin for comfort, provides a controlled path for static electricity discharge that prevents interference with the electrocardiogram signal, thus transforming the potential harm into a benefit.
