Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single wireless power transmitter charges multiple wireless power receivers, then device complexity is reduced, but power distribution efficiency deteriorates because different receivers require different power amounts
Solution Approach 1:
The system segments the wireless power transmission function by deploying multiple transmitters (first, second, and third transmitters) that can independently serve different receivers. Each transmitter can be selectively activated based on receiver requirements, enabling efficient power distribution to multiple devices simultaneously without requiring a single complex transmitter to handle all devices
2Productivity
If power is transmitted to multiple wireless power receivers simultaneously, then charging productivity increases, but control complexity increases due to different power requirements and position changes
Solution Approach 1:
The control system dynamically adjusts transmission parameters based on real-time receiver positions and power requirements. The controller receives information from each receiver (including position and power needs) and calculates optimal transmission parameters for each transmitter-receiver pair, enabling simultaneous charging of multiple devices with varying requirements through adaptive parameter adjustment
Solution Approach 2:
The system implements feedback mechanisms where receivers transmit information about their position, power requirements, and charging status back to the controller. The controller uses this feedback to continuously optimize transmission parameters and power distribution, managing multiple receivers efficiently through real-time information exchange and adaptive control
3Loss of energy
If transmission parameters are optimized for each receiver, then power transmission efficiency improves, but information processing complexity increases
Solution Approach 1:
The system optimizes power transmission efficiency by dynamically adjusting transmission parameters (such as frequency, power level, and beam direction) for each transmitter based on receiver-specific information. The controller calculates optimal parameters for each transmitter-receiver pair considering factors like distance, position, and power requirements, thereby minimizing energy loss while managing information processing through systematic parameter optimization
