Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a round wire structure is used for transmission lines in clothes, then electrical connection is achieved, but the wire is hard to fix and causes uncomfortable stiff touch
Solution Approach 1:
The patent replaces rigid round wires with flexible flat conductive fibers that can be woven into textile fabrics. The flat conductive fiber maintains electrical conductivity while providing a soft, comfortable touch that integrates seamlessly with clothing, eliminating the stiff sensation of traditional wires.
Solution Approach 2:
The patent uses composite structures combining conductive fibers with insulating materials in a woven textile configuration. This composite approach allows the conductive element to be embedded within the fabric matrix, achieving both electrical connection and comfort through the textile's inherent flexibility.
2Object-affected harmful factors
If conductive film material is coated on wires for shielding, then noise resistance is improved, but the structure becomes complex and uncomfortable for wearing
Solution Approach 1:
The patent merges the shielding function directly into the textile structure by weaving conductive fibers throughout the fabric. This integration eliminates the need for separate shielding coatings or layers, as the conductive textile itself provides both signal transmission and noise shielding capabilities.
Solution Approach 2:
The patent uses thin, flexible conductive fibers woven into the textile to provide shielding. This approach replaces bulky coated wire structures with thin, comfortable textile layers that maintain effectiveness while improving wearability.
3Ease of operation
If flat wire structure is used, then comfort is improved, but it cannot combine with textiles or be sewed thereon
Solution Approach 1:
The patent designs the flat conductive fiber as a textile-compatible element that can be directly woven into fabric using standard weaving techniques. The fiber's flat profile and flexibility allow it to be integrated seamlessly into textile structures, enabling both comfort and adaptability.
