Engineering Contradiction Analysis
1Productivity
If wireless charging is performed using magnetic induction between transmitting and receiving coils, then wireless charging function is achieved, but charging efficiency is suboptimal when devices are in relative displacement
Solution Approach 1:
The system continuously monitors charging efficiency and provides real-time feedback to the user through prompt signals. When efficiency drops below a threshold, the system notifies the user to adjust device position, creating a closed-loop control that maintains optimal charging performance without requiring perfect initial positioning
Solution Approach 2:
The system automatically detects charging efficiency and generates displacement indications without requiring user intervention. The user simply needs to follow the prompt signals to move devices, making the optimization process self-service rather than requiring manual positioning adjustments
2Productivity
If real-time monitoring of charging efficiency is implemented, then charging performance is optimized, but system complexity increases
Solution Approach 1:
The system replaces complex mechanical positioning mechanisms with electronic monitoring and software-based efficiency calculation. By using existing wireless communication and power management circuits to detect and calculate charging efficiency, the system avoids adding mechanical adjustment components
Solution Approach 2:
The charging efficiency monitoring system serves multiple functions: it detects charging status, calculates efficiency metrics, generates displacement indications, and provides user notifications. This multi-functionality reduces the need for separate dedicated components for each function
