Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional power converter modulators are used to regulate capacitor droop, then voltage regulation is achieved, but the system requires large switching transistors and experiences substantial switching losses
Solution Approach 1:
The patent replaces conventional mechanical/electronic switching transistors with a resonant inductive energy transfer system. The primary resonant circuit and secondary resonant circuit enable wireless-like inductive coupling to transfer energy, eliminating the need for large switching transistors and their associated switching losses in high-power modulator systems
Solution Approach 2:
The system employs periodic resonant oscillations at specific frequencies in both primary and secondary circuits. By tuning the resonant frequencies to match, energy transfers efficiently in periodic cycles, enabling voltage regulation through resonant coupling rather than through lossy switching operations
2Loss of energy
If resonant capacitors and transformers are added to reduce switching losses, then energy efficiency improves, but device complexity increases significantly
Solution Approach 1:
The patent merges the functions of multiple separate components into integrated resonant circuits. The primary resonant circuit combines inductors and capacitors into a unified resonant system, as does the secondary circuit, reducing the number of discrete components while achieving efficient energy transfer and voltage regulation
3Stability of the object's composition
If bouncer modulators with auxiliary capacitors and inductors are used to compensate droop, then voltage flatness improves, but the system requires expensive well-regulated switching power supplies
Solution Approach 1:
The resonant system is self-regulating through its natural oscillatory behavior. The resonant circuits automatically adjust energy transfer based on their inherent frequency characteristics and coupling conditions, eliminating the need for expensive external switching power supplies and complex control systems while maintaining voltage flatness
