Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If magnetic resonance phenomena are used for energy transfer, then energy transfer efficiency is improved, but frequency adaptability deteriorates (fixed frequency required)
Solution Approach 1:
The patent changes the fundamental operating parameter from resonant frequency to pulsed DC excitation. By using square wave pulses with variable duty cycles and frequencies, the system can adapt to different energy demands without being constrained to a fixed resonant frequency, thus resolving the contradiction between efficiency and adaptability
Solution Approach 2:
The system dynamically adjusts pulse width, pulse frequency, and duty cycle based on real-time feedback from the load. This dynamic control allows the system to maintain optimal performance across varying energy demands while avoiding the fixed frequency constraint of resonant systems
2Length of stationary object
If resonant systems are used for energy transfer, then energy transfer distance is improved, but control flexibility deteriorates (cannot handle variable frequency demands)
Solution Approach 1:
The patent implements dynamic control of pulse parameters (width, frequency, duty cycle) based on feedback from the load's energy demands. This allows the system to maintain effective coupling over varying distances while adapting to different frequency requirements, combining the benefits of distance and flexibility
3Adaptability or versatility
If pulse width and rate control is implemented, then energy transfer adaptability is improved, but system complexity increases (requires digital power electronics and microcontrollers)
Solution Approach 1:
The patent uses feedback from the load's status data to dynamically adjust pulse parameters. This closed-loop control enables high adaptability to varying energy demands while using standard digital power electronics and microcontrollers, making the complexity manageable and justified by the performance gains
