Solution Overview
Problem
Conventional electrical heating clothing for outdoor activities has limited heating effectiveness, relies solely on batteries or external power, and lacks the ability to self-charge or convert kinetic energy into electricity, making it inconvenient for prolonged use.
Innovation Solution
A multifunctional smart garment textile composed of conductive yarns with cotton threads, multiwalled carbon nanotubes, and iodine-modified polypyrrole, integrated with a piezoelectric material like poly (vinylidenefluoride-co-trifluoroethylene) to enhance electrical heating, thermal conductivity, and convert kinetic energy into electricity for self-charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional electrical heating clothing uses batteries or external power sources, then heating function is provided, but the device complexity and user burden increase due to carrying multiple power sources
Solution Approach 1:
The patent implements self-service by enabling the heating garment to generate its own power through body motion. The kinetic energy harvesting system converts the wearer's movements into electrical energy, eliminating the need for external batteries or power sources. This resolves the contradiction by making the system self-sufficient while maintaining the heating function.
Solution Approach 2:
The patent uses composite materials including piezoelectric materials and conductive fabrics integrated into the garment structure. These composite materials enable both power generation through body motion and efficient heat distribution, resolving the contradiction by combining multiple functions in a unified material system.
2Temperature
If conventional heating clothing relies on external power sources, then heating is achieved, but the duration of action is limited by battery capacity
Solution Approach 1:
The patent achieves continuity of useful action by continuously converting the wearer's body motion into electrical energy during outdoor activities. As long as the user remains active, the system continuously generates power to sustain heating, eliminating the interruption caused by battery depletion and extending heating duration indefinitely.
Solution Approach 2:
The self-charging mechanism through kinetic energy harvesting allows the garment to continuously replenish its own power supply during use. This resolves the duration limitation by making the system self-sustaining rather than dependent on finite battery capacity.
3Device complexity
If heating clothing uses simple battery power, then the structure is simple, but the adaptability is reduced as it cannot convert kinetic energy or provide multiple functions
Solution Approach 1:
The patent implements multi-functionality by integrating kinetic energy harvesting, heating, and potential lighting functions into a single garment system. The same piezoelectric materials and conductive fabric structure serve multiple purposes: generating power from motion, distributing heat, and potentially providing light emission. This resolves the contradiction by adding versatility without proportionally increasing complexity.
