Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LEDs are fixed directly to the strap by welding or gluing, then the electrical connection is established, but the assembly process becomes complex and costly
Solution Approach 1:
The patent introduces a printed circuit board as an intermediary component between the LEDs and the textile strap. The PCB provides standardized mounting holes for securing LEDs and includes pre-designed conductive traces that establish electrical connections, eliminating the need for direct welding or gluing of LEDs to the fabric. This mediator simplifies the assembly process while ensuring reliable electrical connections.
2Reliability
If LEDs are fixed by welding or gluing, then electrical connection is achieved, but the strap cannot be reused when electrical elements need to be changed
Solution Approach 1:
The patent segments the device into distinct modular components: the textile strap, the printed circuit board, and the electrical elements (LEDs). The PCB acts as an intermediate module that can be detached from the strap, allowing LEDs to be easily replaced or upgraded without damaging the strap itself. This segmentation enables the strap to be reused while adapting to different electrical element requirements.
3Reliability
If poor welding or bonding occurs, then electrical connection fails, but recovery operations become long, complex and costly
Solution Approach 1:
The printed circuit board serves as a protective intermediary layer between the textile strap and the electrical elements. Standardized through-hole mounting techniques on the PCB provide robust mechanical and electrical connections that are resistant to failure. If connection issues occur, the modular design allows for easy replacement of the PCB or LEDs without complex recovery operations on the strap itself, significantly reducing repair time and cost.
