Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high power transmission is used in wireless charging, then charging efficiency is improved, but temperature control deteriorates leading to overheating
Solution Approach 1:
The patent implements dynamic power adjustment by continuously monitoring temperature parameters and adapting the charging power in real-time. The system transitions from static high power transmission to dynamic power control, where the power level is adjusted based on current temperature conditions, thus maintaining charging efficiency while preventing overheating.
Solution Approach 2:
The patent employs a feedback mechanism where temperature parameters are continuously monitored during wireless charging. This temperature feedback is used to adjust the power transmission level, creating a closed-loop control system that balances charging efficiency with temperature management, preventing overheating while maintaining optimal charging performance.
2Temperature
If power control algorithms are adjusted to reduce heat, then temperature control is improved, but charging efficiency deteriorates
Solution Approach 1:
The system uses dynamic power adjustment algorithms that adapt the charging power based on real-time temperature conditions. Rather than using fixed low power settings, the system dynamically optimizes power levels to maintain temperature control while maximizing charging efficiency at each moment, resolving the trade-off between temperature management and charging performance.
Solution Approach 2:
The patent changes the power transmission parameter dynamically based on temperature parameters. By adjusting the power level as a variable parameter rather than a fixed value, the system can optimize both temperature control and charging efficiency, achieving the best balance between these two competing objectives through continuous parameter adaptation.
3Adaptability or versatility
If wireless charging is applied to more terminals, then adaptability is improved, but heat dissipation capacity deteriorates
Solution Approach 1:
The patent implements individualized temperature management for each power receiving device by monitoring specific temperature parameters of each device and applying tailored power control algorithms. This local quality approach allows the system to maintain adaptability across multiple terminals while managing heat dissipation capacity on a per-device basis, preventing overall system overheating.
Solution Approach 2:
The system adjusts power transmission parameters individually for each terminal based on its specific temperature conditions and charging needs. By changing power parameters dynamically for each device rather than using a uniform approach, the system maintains high adaptability while effectively managing the heat dissipation capacity of the overall system.
