Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the information transmission means and power transmission means are configured to independently operate, then the device can perform both functions simultaneously, but electromagnetic induction in the power transmission means generates noise in wireless communication, degrading communication quality
Solution Approach 1:
The patent implements periodic action by dividing operation into alternating transmission periods and non-transmission periods. During transmission periods, information transmission occurs; during non-transmission periods, power transmission occurs. This time-division approach eliminates electromagnetic noise interference by ensuring the two functions never operate simultaneously, while still providing both functionalities through sequential execution.
2Object-affected harmful factors
If exclusive control is implemented to prevent electromagnetic noise, then communication quality is maintained, but charging is not immediately started when battery level is critical, potentially causing battery exhaustion during information transmission
Solution Approach 1:
The patent applies preliminary action by continuously monitoring battery charge levels and pre-scheduling power transmission during upcoming non-transmission periods when the battery level falls below a threshold. This allows the system to proactively charge the battery before critical exhaustion occurs, ensuring reliable operation while maintaining the exclusive control that prevents electromagnetic noise.
3Reliability
If the system alternates between transmission and non-transmission periods with synchronized power transmission, then communication quality is maintained and battery exhaustion is prevented, but the device cannot perform both functions simultaneously
Solution Approach 1:
The system accepts reduced functional throughput as a necessary trade-off for reliability. By implementing periodic action with synchronized power transmission during non-transmission periods, the patent ensures stable operation and prevents battery exhaustion, while the alternating nature of the cycles inherently limits simultaneous function execution.
