Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sheet-type heating element is simply attached to an outer element, then the structure is simple, but when applied to a curved area of the body, the sheet-type heating element is not able to be completely adhered to the curved area and does not generate heat at a uniform temperature
Solution Approach 1:
The heating element is divided into multiple independent heating sections (first heating section, second heating section, third heating section) that can independently conform to different curved areas of the body. Each heating section has its own heating wire configuration optimized for specific body contours, enabling complete adherence to curved surfaces while maintaining structural manageability through modular design.
Solution Approach 2:
Different heating sections have different heating wire patterns and configurations tailored to specific body areas. The first heating section has a specific wire arrangement for one curved area, the second heating section has a different arrangement for another curved area, and the third heating section has yet another configuration. This local optimization ensures uniform heat generation across all curved surfaces without requiring a complex unified structure.
2Reliability
If conventional sheet masks utilize various methods of improving the composition of effective components or cosmetic materials, then the absorption efficacy is improved, but the manufacturing cost is increased and efficiency is decreased relative to the increased cost
Solution Approach 1:
The patent replaces chemical/compositional improvements with a thermal field approach. Instead of modifying the composition of effective components or cosmetic materials to enhance absorption, the invention uses a heating element that provides thermal energy to promote penetration of existing components into the skin. This substitution of mechanical/thermal action for chemical optimization maintains manufacturing cost efficiency while achieving improved absorption efficacy.
Solution Approach 2:
The invention changes the temperature parameter by introducing a heating element that raises the skin temperature during mask application. This parameter change (temperature increase) enhances the penetration and absorption of cosmetic materials without requiring changes to the material composition itself, thereby avoiding increased manufacturing costs while improving absorption efficacy.
3Temperature
If a sheet-type heating element is used to provide heat, then heating function is added, but the sheet-type heating element simply generates heat and does not generate heat at a uniform temperature
Solution Approach 1:
The heating element is segmented into multiple independent heating sections, each with its own heating wire configuration. This segmentation allows each section to be optimized for uniform heat distribution across its specific area, preventing hot spots and ensuring consistent temperature across the entire heating surface while maintaining overall heating efficiency.
Solution Approach 2:
Each heating section has locally optimized heating wire patterns designed to achieve uniform temperature distribution in its specific region. The first heating section has a wire configuration optimized for its area, the second heating section has a different configuration for its area, and the third heating section has yet another configuration. This local optimization ensures uniform heat generation across all sections without sacrificing overall heating productivity.
