Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If power transmission is stopped when temperature exceeds predetermined value, then temperature control is improved, but power supply continuity deteriorates
Solution Approach 1:
The patent implements dynamic power adjustment by continuously monitoring temperature and adaptively changing the power transmission level. Instead of binary stop/start control, the system dynamically modulates power output to maintain temperature within safe limits while ensuring continuous power supply to the reception apparatus.
Solution Approach 2:
The system changes the power transmission parameter based on detected temperature conditions. By adjusting the power level according to real-time temperature feedback, the system maintains both temperature safety and power supply continuity, resolving the contradiction between these two requirements.
2Productivity
If power transmission is performed at high power, then power transmission efficiency is improved, but temperature rise deteriorates
Solution Approach 1:
The patent employs a feedback mechanism where the detection unit continuously monitors temperature and feeds this information back to the power transmitting unit. Based on the temperature feedback, the system adjusts power transmission levels to prevent excessive temperature rise while maintaining efficient power transfer within safe operating limits.
Solution Approach 2:
The system dynamically adjusts power transmission levels based on real-time temperature conditions. By making power output variable rather than fixed, the system can operate at high efficiency when temperatures are acceptable and reduce power when temperature thresholds are approached, thus resolving the contradiction between efficiency and temperature control.
3Reliability
If power transmission is continuously performed, then power supply continuity is improved, but temperature accumulation deteriorates
Solution Approach 1:
The patent implements periodic temperature monitoring and power adjustment cycles. The detection unit periodically checks temperature, and the power transmitting unit periodically adjusts its output based on these checks. This periodic action ensures continuous power supply while preventing temperature accumulation through regular adjustments.
Solution Approach 2:
Through continuous temperature feedback, the system maintains power transmission continuity while preventing temperature accumulation. The feedback loop enables real-time adjustments that keep the system operating within safe temperature limits throughout continuous operation.

AI summary
A power transmission apparatus that performs power transmission wirelessly to a power reception apparatus, performs power transmission wirelessly, detects a temperature inside or in a periphery of the power transmission apparatus, sets a value for power that can be transmitted to the power reception apparatus under a condition where the detected temperature does not exceed a predetermined temperature when power transmission to the power reception apparatus is performed, and performs power transmission to the power reception apparatus based on the set value for power.
