Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If horizontal wireless charger design is used, then adaptability to different device models is improved, but heat dissipation effect deteriorates due to complicated air channels
Solution Approach 1:
The mounting cavity is divided into a first chamber and a second chamber using a baffle. The first chamber is dedicated to heat dissipation functions with the fan and air channels, while the second chamber houses the coil module. This segmentation allows independent optimization of heat dissipation pathways without compromising charging functionality, directly resolving the heat dissipation issue in horizontal chargers.
Solution Approach 2:
A fan is introduced to create forced air convection through the first chamber, establishing controlled air flow paths from the first vent to the second vent. This pneumatic approach replaces passive, complicated air channels with an active cooling system that efficiently removes heat while maintaining the horizontal charger's adaptability.
2Temperature
If vertical wireless charger design is used, then heat dissipation structure is simplified, but adaptability to different device models deteriorates due to fixed coil positions
Solution Approach 1:
The horizontal charger design with the separated first chamber (for heat dissipation) and second chamber (for coil module) creates a universal structure that can accommodate various device models. The air channel system in the first chamber serves multiple devices simultaneously, while the coil module in the second chamber maintains charging capability across different form factors, achieving both simplified heat dissipation and broad adaptability.
3Temperature
If fan is added to improve heat dissipation, then heat dissipation effect is improved, but device complexity increases
Solution Approach 1:
By segmenting the mounting cavity into distinct chambers, the patent isolates the fan and air channel components to the first chamber, separating the heat dissipation subsystem from the charging subsystem in the second chamber. This modular segmentation manages device complexity by organizing components into functional zones, making the system more maintainable and easier to manufacture despite adding active cooling.
