Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If non-contact power supply is performed during signal readout, then power supply continuity is improved, but image quality deteriorates due to electromagnetic field fluctuations
Solution Approach 1:
The power supply frequency is set to match the signal readout frequency, creating a periodic synchronization where power is supplied at intervals that coincide with signal acquisition cycles. This periodic action ensures continuous power availability while the synchronized timing prevents electromagnetic interference from corrupting the readout signals.
Solution Approach 2:
The invention changes the power supply frequency parameter to match the signal readout frequency, and adjusts the duty cycle of power supply to occur during specific time windows that do not interfere with signal acquisition. By dynamically adjusting these parameters, the system maintains power continuity while avoiding image quality degradation.
2Adaptability or versatility
If non-contact power supply frequency fluctuates, then power supply flexibility is improved, but signal reading accuracy deteriorates
Solution Approach 1:
The system incorporates feedback mechanisms that monitor the signal readout process and adjust the power supply frequency in real-time to maintain synchronization. This feedback loop ensures that even if initial frequency settings drift, the system automatically corrects to maintain the precise frequency matching required for accurate signal reading while preserving power supply flexibility.
3Adaptability or versatility
If internal power supply is used during non-contact power supply interruption, then power supply independence is improved, but power availability deteriorates
Solution Approach 1:
The invention maintains continuous useful action by ensuring non-contact power supply never fully interrupts during critical operations. By synchronizing power supply with signal readout cycles and maintaining appropriate duty cycles, the system eliminates the need for internal power reserves while ensuring continuous power availability, thereby achieving both power independence and adequate power availability.
