Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If quick wireless charging operation is performed without radiator fan, then charging speed is improved, but heat dissipation performance deteriorates
Solution Approach 1:
The patent implements dynamic control of the radiator fan based on real-time temperature monitoring. The microcontroller adjusts fan rotation speed according to temperature thresholds, enabling the cooling system to adapt dynamically to charging conditions. This resolves the contradiction by allowing high-speed charging when temperatures are acceptable while activating cooling when heat becomes excessive.
Solution Approach 2:
The system changes operational parameters (fan speed, charging power) based on temperature conditions. By monitoring temperature and adjusting fan rotation speed accordingly, the system optimizes both charging performance and thermal management, resolving the trade-off between charging speed and heat dissipation.
2Device complexity
If status light shows only two lighting scenarios, then device complexity is reduced, but information feedback capability deteriorates
Solution Approach 1:
The status light is designed to perform multiple functions by displaying different lighting scenarios (colors, patterns, intensities) to indicate various operational states including enabled, standby, charging, full charge, and failure conditions. This single component provides comprehensive feedback without requiring multiple separate indicators, resolving the contradiction between simplicity and information completeness.
3Device complexity
If wireless charging base lacks adjustable charging power, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The system dynamically adjusts charging power based on temperature conditions and charging stage. The microcontroller modifies power output levels automatically, enabling the same device to adapt to different charging requirements without requiring manual user adjustment or complex control interfaces.
