Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed timeout time is used for communication between wireless power transmitter and receiver, then the communication protocol is simple to implement, but the system cannot adapt to changing communication speeds leading to inefficiency and potential damage
Solution Approach 1:
The timeout time is changed from a fixed value to a dynamic value that adapts to communication speed changes. The communication/control circuit monitors communication conditions and adjusts the timeout time accordingly, allowing the system to respond to varying communication speeds between transmitter and receiver while maintaining protocol operability.
Solution Approach 2:
The timeout time parameter is modified based on communication speed variations. By changing this critical timing parameter dynamically, the system adapts to different communication conditions without requiring complete protocol redesign, thus balancing adaptability with implementation feasibility.
2Reliability
If authentication is performed without considering communication speed variations, then the authentication process is fast and simple, but incompatible power transfers may occur causing potential damage
Solution Approach 1:
Authentication is performed with consideration of communication speed characteristics before power transfer begins. The system preliminarily assesses communication conditions and adjusts authentication timing accordingly, ensuring reliable verification while minimizing delays in the power transfer process.
3Productivity
If the timeout time is not adjusted based on communication speed, then the system operation is straightforward, but efficient protocol operation cannot be achieved
Solution Approach 1:
The communication/control circuit continuously monitors communication speed and provides feedback to adjust the timeout time. This feedback mechanism enables the system to optimize power transfer efficiency by adapting timeout parameters to actual communication conditions while maintaining automated operation that does not require complex manual intervention.

Function Achieved in This Case
This system allows for stable and efficient power transfer by adapting to changing communication speeds, reducing the risk of damage from incompatible power reception and enhancing user experience through optimized protocol operation and authentication.
Implementation Method 1
The wireless power transfer technique includes diverse methods, such as a method of transferring power by using magnetic coupling
Implementation Method 2
The magnetic resonance method is similar to the magnetic induction method in that is uses a magnetic field. However, the magnetic resonance method is different from the magnetic induction method in that energy is transmitted due to a concentration of magnetic fields on both a transmitting end and a receiving end, which is caused by the generated resonance.
