Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional antennas are used in wearable devices, then signal transmission function is achieved, but space is limited and signal quality deteriorates due to interference
Solution Approach 1:
The patent transitions antenna integration from the device body (2D plane) to the textile band (3D flexible structure), utilizing the band's surface area and spatial flexibility to accommodate larger antenna elements without constraining the device body dimensions. This dimensional shift resolves the space limitation while maintaining signal quality.
Solution Approach 2:
The patent employs composite textile materials that combine conductive elements (metallic threads, conductive coatings, liquid metal cores) with flexible textile substrates. This composite approach enables the antenna to achieve both electrical functionality and mechanical flexibility, reducing interference while maintaining signal integrity in the wearable context.
2Adaptability or versatility
If flexible and elastic straps are used for wearable devices, then comfort and adaptability are improved, but antenna performance deteriorates due to material limitations
Solution Approach 1:
The patent integrates antennas directly into flexible textile bands that can bend, stretch, and conform to body movements. The textile substrate acts as a flexible carrier that maintains antenna structural integrity while enabling the strap to adapt to user comfort requirements without compromising antenna performance.
Solution Approach 2:
The use of composite textile materials with conductive components embedded within flexible fabric structures enables the strap to simultaneously provide mechanical flexibility for comfort and electrical conductivity for reliable antenna operation, resolving the contradiction between adaptability and performance.
3Volume of moving object
If antenna size is reduced to fit device constraints, then device compactness is improved, but signal loss increases
Solution Approach 1:
The patent relocates the antenna from the compact device body to the extended textile band, effectively utilizing the band's larger surface area and three-dimensional spatial arrangement. This allows the antenna to maintain optimal dimensions for signal transmission while the device body remains compact, as the antenna is distributed along the flexible band rather than confined to the device volume.
