Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the wireless charging mouse continuously outputs displacement detecting signals, then the cursor control responsiveness is improved, but the energy consumption increases and incorrect detection occurs when not in contact with charging board
Solution Approach 1:
The control circuit periodically checks the electromagnetic energy level received from the charging board and discontinuously outputs displacement detecting signals only when the energy level meets the threshold requirement, rather than continuously outputting signals. This periodic verification and conditional signal output reduces energy consumption while maintaining responsive cursor control when properly charged.
Solution Approach 2:
The control circuit receives feedback about the electromagnetic energy level from the wireless power receiving circuit and adjusts the signal output accordingly. When the received energy is insufficient, the control circuit stops outputting displacement detecting signals, preventing incorrect cursor control and conserving energy. This feedback mechanism ensures responsive operation only when energy conditions are adequate.
2Duration of action of moving object
If the wireless charging mouse outputs displacement detecting signals when electromagnetic energy is insufficient, then the operational continuity is improved, but the detection accuracy deteriorates
Solution Approach 1:
The control circuit continuously monitors the electromagnetic energy level received from the charging board and uses this feedback to determine whether to output displacement detecting signals. When the energy level falls below the threshold, the control circuit stops signal output, preventing inaccurate detection. This feedback-based decision ensuring detection accuracy is maintained while operational continuity is preserved through conditional operation.
Solution Approach 2:
The system changes the operational parameter (signal output state) based on the electromagnetic energy level parameter. When the energy parameter drops below a threshold value, the system transitions from signal output mode to signal stop mode, preventing detection errors. This parameter-based control ensures detection accuracy is maintained by adapting operation to energy availability.
3Measurement precision
If the wireless charging mouse stops outputting displacement detecting signals when electromagnetic energy is low, then the detection accuracy is improved, but the operational interruptions increase
Solution Approach 1:
The control circuit uses real-time feedback from the wireless power receiving circuit about electromagnetic energy levels to make intelligent decisions about signal output. This feedback mechanism allows the system to maintain detection accuracy by stopping signals only when necessary, minimizing unnecessary operational interruptions while ensuring accurate detection when signals are active.
Solution Approach 2:
The system performs preliminary checks of electromagnetic energy levels before outputting displacement detecting signals. By verifying energy sufficiency in advance, the system prevents detection errors from occurring rather than correcting them afterward, reducing operational interruptions caused by inaccurate detection and subsequent corrections.
