Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is read at a fixed cycle according to the accepted transmission rate, then data transmission follows the ideal data rate, but coil misalignment causes high-frequency noise interference and incorrect data decoding
Solution Approach 1:
The patent applies preliminary action by pre-calculating and adding a data reading timing margin to the fixed cycle before data reading occurs. This margin is computed based on signal attenuation characteristics and coil misalignment parameters, allowing the system to proactively adjust the data reading timing to avoid noise interference zones, thereby ensuring accurate data decoding while maintaining the ideal transmission rate
2Reliability
If a data reading timing margin is added to the fixed cycle to account for signal attenuation, then data determination errors are reduced, but the data reading timing deviates from the ideal transmission rate cycle
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the data reading timing parameter based on signal attenuation characteristics and coil misalignment conditions. The data reading timing margin is calculated as a function of these parameters, allowing the system to optimize data reading timing for accuracy while minimizing impact on overall transmission rate through controlled parameter variation
3Use of energy by moving object
If load-shift keying is used to transmit data one bit by one bit, then power consumption is reduced, but the system requires continuous power supply from the speech processor battery
Solution Approach 1:
The patent applies feedback by implementing a timing margin calculation and adjustment mechanism that monitors signal attenuation and coil misalignment conditions in real-time. This feedback loop allows the system to optimize data reading timing dynamically, ensuring accurate data reception with minimal power consumption while extending battery life through efficient power usage
