Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless power transmission is implemented using resonant circuits, then wired connections are eliminated improving portability, but energy loss increases due to internal and radiation resistances in the resonators
Solution Approach 1:
The patent applies negative resistance elements (active components) to compensate for the harmful energy losses in the resonators. The negative resistance converts the harmful effect of positive resistance (energy dissipation) into a beneficial effect by providing energy back to the resonant system, thereby maintaining high Q factors and improving transmission efficiency while preserving wireless portability
2Ease of operation
If energy is transmitted over longer distances through mutual resonance, then portability and convenience are improved, but energy transfer efficiency decreases due to increased losses
Solution Approach 1:
The patent implements energy compensation mechanisms that actively monitor and compensate for energy losses in the resonant system. The negative resistance elements provide feedback compensation by detecting energy dissipation and injecting compensating energy, thereby maintaining efficient power transfer over extended distances without requiring wired connections
3Productivity
If the Q factor of resonators is increased to reduce energy loss, then energy transfer efficiency improves, but device complexity increases due to additional compensation components
Solution Approach 1:
The patent integrates negative resistance elements that serve multiple functions: they compensate for resistive losses, maintain high Q factors, enable wireless operation, and support extended transmission distances. This multi-functionality achieves improved energy transfer efficiency without proportionally increasing device complexity, as the same active components address multiple technical challenges simultaneously
