Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional bedding materials are used, then manufacturing cost and simplicity are maintained, but thermal conductivity is insufficient causing overheating and discomfort
Solution Approach 1:
The patent applies composite materials by combining at least one cooling fiber (such as rayon, nylon, or polyester with specific thermal properties) with at least one non-cooling fiber. This composite structure enables the fabric to achieve superior thermal conductivity and cooling effects while maintaining structural integrity and manufacturability, directly resolving the contradiction between temperature control and material complexity
2Reliability
If cooling materials are used, then thermal conductivity improves providing cool touch sensation, but material structure complexity increases
Solution Approach 1:
The patent applies local quality by creating a fabric where cooling fibers are strategically distributed among non-cooling fibers, rather than uniformly mixing all fibers. This allows specific regions of the fabric to have enhanced cooling properties where needed, while maintaining overall structural simplicity and manufacturability, thus improving cooling reliability without excessive complexity
Solution Approach 2:
The patent applies parameter changes by carefully controlling the proportion of cooling fibers (at least 10% by weight) and adjusting fiber diameter, length, and arrangement parameters. These parameter optimizations enable the material to achieve reliable cooling effects while keeping the fiber composition manageable and suitable for conventional manufacturing processes
3Loss of energy
If conventional materials are used, then material simplicity is maintained, but heat dissipation capability is insufficient causing sleep discomfort
Solution Approach 1:
The patent applies porous materials by incorporating fibers with specific porosity characteristics that facilitate air circulation and heat dissipation. The composite fiber structure creates micro-channels and pores that enhance convective heat transfer, improving body heat dissipation capability while maintaining compatibility with standard textile manufacturing processes
