Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If natural heat dissipation is used, then device simplicity is maintained, but charging speed is greatly limited
Solution Approach 1:
The patent implements self-service by using the heat generated during wireless charging to drive the cooling system. The Peltier element utilizes the temperature differential created by the charging process itself to generate electricity that powers the fan, making the system self-sufficient without requiring external power sources for cooling.
Solution Approach 2:
The patent converts the harmful heat generated during charging into a beneficial resource. The heat that would normally need to be dissipated is instead captured by the Peltier element to generate electrical energy, which is then used to power the active cooling system, turning a problem into a solution.
2Temperature
If one fan is used for heat dissipation, then active cooling is provided, but heat dissipation effectiveness is insufficient
Solution Approach 1:
The patent segments the heat dissipation function into two distinct components: a Peltier element for active heat transfer and a fan for air circulation. This segmentation allows each component to specialize in its function, with the Peltier element creating a temperature differential and the fan providing forced convection, together achieving superior cooling effectiveness.
Solution Approach 2:
The patent merges the heating function (wireless charging) with the cooling function (heat dissipation system) into an integrated system. The charging process generates heat that is directly utilized by the Peltier element, and the entire cooling system is powered by the energy harvested from the charging process itself, creating a unified thermodynamic system.
3Productivity
If electronic device uses active heat dissipation, then charging performance is improved, but device structure becomes more complex
Solution Approach 1:
The patent implements multi-functionality by designing the wireless charging base to perform both charging and cooling functions, with the cooling system being self-powered by the charging process. The base unit serves as both the power transmission device and the thermal management system, eliminating the need for separate active cooling components in the electronic device being charged.
