Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If Peltier elements are used for active cooling, then cooling effect is achieved, but cost and energy consumption increase
Solution Approach 1:
The patent replaces the electrical Peltier cooling system with a mechanical airflow generation system. A brush unit with radially extending structures generates airflow through rotation, which evaporates a cooling medium (water) to produce cooling effect. This mechanical approach eliminates the need for expensive Peltier elements and reduces energy consumption significantly.
Solution Approach 2:
The patent utilizes the phase transition of water from liquid to vapor through evaporation. The generated airflow accelerates the evaporation of water from the brush unit, and this phase transition absorbs heat from the skin surface, providing effective cooling without requiring complex electrical cooling systems.
2Temperature
If Peltier elements are used for active cooling, then cooling effect is achieved, but device complexity increases due to heat sinks or fans
Solution Approach 1:
The patent extracts and eliminates the complex heat management components (heat sinks, fans) from the cooling system. By using evaporative cooling through airflow generation, the system naturally dissipates heat through the phase change of water, removing the need for additional heat rejection components and simplifying the overall device structure.
Solution Approach 2:
The cooling system is self-regulating through the natural evaporation process. The airflow generated by the rotating brush unit automatically promotes water evaporation, which in turn provides cooling. The system uses its own operational motion (brush rotation) to drive the cooling mechanism, eliminating the need for separate control systems for heat management.
3Temperature
If passive cooling elements are pre-cooled in freezer, then cooling effect is achieved, but storage space and convenience are reduced
Solution Approach 1:
The cooling element generates its own cooling effect during operation through the evaporative cooling mechanism. The brush unit, when rotated, automatically generates airflow that evaporates the cooling medium, producing cooling without requiring pre-cooling or external freezer storage. The system activates cooling only when needed through its operational motion.
Solution Approach 2:
The cooling effect is activated periodically when the brush unit rotates during use. The rotational motion periodically generates airflow that drives evaporation, providing cooling in a on-demand manner rather than requiring continuous pre-cooling or storage in freezer conditions.
