Engineering Contradiction Analysis
1Reliability
If the resonance frequency changes due to component variations, then the communication characteristics cannot be maintained, but adding additional components for calibration increases device complexity
Solution Approach 1:
The radio communication device automatically measures its own resonance frequency and adjusts the phase of transmitted radio signals accordingly. The CPU executes control programs to autonomously maintain optimal communication characteristics without requiring external calibration equipment or additional hardware components, thereby resolving the contradiction between reliability and device complexity
Solution Approach 2:
The system dynamically changes the phase parameter of the transmitted radio signal based on the measured resonance frequency. By adjusting this key parameter in response to component variations, the device maintains optimal communication characteristics without adding physical components, thus improving reliability while keeping device complexity low
2Reliability
If manual calibration is performed to maintain optimal phase, then communication quality improves, but the process becomes time-consuming and complex
Solution Approach 1:
The device performs self-calibration by automatically measuring its resonance frequency and adjusting signal phase accordingly. This eliminates the need for manual calibration procedures, significantly reducing calibration time while maintaining high communication quality, thus resolving the contradiction between reliability and time loss
Solution Approach 2:
The system performs resonance frequency measurement and phase adjustment automatically during device operation or initialization, eliminating the need for separate manual calibration steps. This preliminary automated action ensures optimal communication quality is achieved without time-consuming manual intervention
