Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external hanging method is used to connect electronic components to clothing, then compatibility and comfort are improved, but thermal uniformity and heat generating efficiency deteriorate
Solution Approach 1:
The patent merges the electronic component housing with the clothing structure itself, making the clothing articles (jacket, pants, etc.) serve as the housing. This integration eliminates the need for separate external hanging components while maintaining compatibility and comfort, and enables uniform heat distribution through the clothing material.
Solution Approach 2:
The patent uses composite material structure where the clothing housing comprises multiple layers including heat generating layer, heat insulating layer, and heat dissipating layer. This composite structure enables both good thermal uniformity and heat generating efficiency while maintaining wearability and comfort.
2Adaptability or versatility
If electronic components are directly attached to clothing, then compatibility is improved, but flexibility and stretchability deteriorate
Solution Approach 1:
The patent employs flexible and stretchable materials for the clothing housing, including flexible battery, flexible heating elements, and stretchable fabric structures. This allows the electronic components to be directly integrated into the clothing while maintaining flexibility and stretchability for comfortable movement.
3Ease of manufacture
If existing manufacturing process is used, then ease of manufacture is improved, but thermal uniformity and heat generating efficiency deteriorate
Solution Approach 1:
The patent segments the heating system into multiple independent heating zones with separate heating elements distributed throughout the clothing. This segmentation allows each zone to be manufactured using existing processes while achieving overall uniform heat distribution and high heat generating efficiency through the combined effect of multiple zones.
