Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air gap between primary and secondary coils is increased, then the safety and wireless power transmission capability are improved, but the power transmission efficiency deteriorates
Solution Approach 1:
The patent applies dynamics by making the operating parameters (frequency, phase angle) of the power circuits dynamically adjustable based on the detected air gap size. The system transitions from static fixed parameters to dynamic adaptive parameters that change in real-time according to the air gap conditions, thereby maintaining optimal power transmission efficiency across varying safety distances.
Solution Approach 2:
The patent implements parameter changes by modifying the frequency and phase angle parameters of the power transmitting and receiving circuits according to the detected air gap size. Different air gap ranges correspond to different parameter settings, allowing the system to adapt its electrical parameters to maintain efficient power transmission while accommodating varying safety distances.
2Adaptability or versatility
If the air gap between primary and secondary coils is increased, then the wireless charging capability is improved, but the coupling coefficient deteriorates
Solution Approach 1:
The patent uses parameter changes by adjusting the frequency and phase angle of the power circuits based on the detected air gap size. When the air gap increases, the system modifies its operating parameters to compensate for the reduced coupling coefficient, thereby maintaining effective wireless charging capability across different transmission distances.
Solution Approach 2:
The patent implements feedback by using a detecting device to measure the air gap size and using this information to regulate the operating parameters of the power circuits. The system continuously monitors the air gap and adjusts its parameters accordingly, creating a closed-loop control system that maintains optimal coupling despite variations in transmission distance.
3Ease of operation
If misalignment between primary and secondary coils occurs, then the ease of operation is improved, but the power transmission efficiency deteriorates
Solution Approach 1:
The patent applies parameter changes by adjusting the frequency and phase angle parameters based on the detected misalignment between primary and secondary coils. When misalignment is detected, the system modifies its operating parameters to compensate for the reduced coupling, thereby maintaining power transmission efficiency without requiring precise manual alignment from the user.
Solution Approach 2:
The patent implements self-service by enabling the contactless transformer system to automatically detect and compensate for misalignment through parameter regulation. The system self-adjusts its operating parameters based on the detected misalignment conditions, eliminating the need for manual intervention or precise alignment procedures by the user.
4Ease of operation
If misalignment between primary and secondary coils occurs, then the ease of operation is improved, but the coupling coefficient deteriorates
Solution Approach 1:
The patent uses parameter changes by modifying the frequency and phase angle of the power circuits based on the detected misalignment. This allows the system to maintain a high coupling coefficient even when misalignment occurs, thereby preserving reliable power transmission while keeping the operation simple and user-friendly.
Solution Approach 2:
The patent implements feedback by using the detecting device to monitor misalignment conditions and using this information to regulate the operating parameters. This closed-loop control ensures that the coupling coefficient is maintained at optimal levels despite misalignment, while the system continues to operate easily without user intervention.
