Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the transmitter antenna operates at high power to improve charging efficiency, then the field emissions exceed the emission threshold level and regulatory compliance is violated
Solution Approach 1:
The system dynamically adjusts the power level of the transmitter antenna based on real-time monitoring of field emissions and receiver characteristics. The controller continuously modifies operating parameters to maintain optimal charging efficiency while ensuring field emissions remain below regulatory thresholds, transitioning from static to dynamic operation.
Solution Approach 2:
The system changes operating parameters including power level, frequency, and modulation depth to adapt to different charging conditions. By adjusting these parameters in response to monitored field emissions and receiver status, the system maintains regulatory compliance while optimizing charging performance across varying conditions.
2Adaptability or versatility
If the system adapts to different vehicle characteristics and charging conditions, then regulatory compliance is maintained, but system complexity increases
Solution Approach 1:
The system employs sensor circuits to monitor field emissions, receiver characteristics, and charging conditions, feeding this information back to the controller. The controller uses this feedback to automatically adjust transmitter operation, enabling adaptability to different vehicles and conditions through a closed-loop control mechanism rather than complex pre-programming.
Solution Approach 2:
The system performs self-adjustment by automatically monitoring its own output and the receiver status, then autonomously modifying its operation to maintain compliance and optimize performance. This self-service capability reduces the need for external control systems and simplifies the overall architecture.

AI summary
Apparatus, system, and method for adaptive charging compliance control are disclosed. A charging station wirelessly charges a vehicle in compliance with emissions regulations. A controller in the charging station obtains information regarding the characteristics of an incoming vehicle and accesses a maximum regulation-compliant power level database based on the vehicle information obtained and determines conditions of the vehicle parked at the charging station. The controller determines and delivers the maximum power level to wirelessly charge the vehicle while maintaining the level of field emissions no greater than the regulatory limit.
