Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a charging pile is used to charge the battery of an electric auxiliary vehicle, then the battery can be charged, but the power supply power and residual power are not monitored or regulated, resulting in inefficient power management
Solution Approach 1:
The patent implements a feedback mechanism where the remote monitoring device continuously receives power information from the wireless charging platform and control devices, monitors residual power levels, and provides real-time feedback to regulate power supply behavior. This closed-loop feedback system enables dynamic adjustment of charging parameters and power distribution, resolving the information loss problem and improving power management efficiency
Solution Approach 2:
The system enables self-service power management by allowing the wireless charging platform and control devices to autonomously monitor their own power status, manage charging sessions, and regulate power supply based on pre-set parameters and real-time conditions, eliminating the need for manual intervention while improving management efficiency
2Use of energy by moving object
If the wireless charging platform charges multiple vehicles simultaneously, then power utilization increases, but power distribution control becomes more complex
Solution Approach 1:
The patent segments the power management system into independent modular components: multiple control devices (one per vehicle), a central wireless charging platform, and a remote monitoring device. Each segment operates semi-autonomously with defined interfaces, enabling simultaneous charging of multiple vehicles while maintaining simplified control logic in each module and reducing overall system complexity
Solution Approach 2:
The wireless charging platform is designed with multi-functionality to serve multiple vehicles simultaneously through standardized charging interfaces and protocols. The platform can dynamically allocate power to different vehicles based on their needs, and the control devices are universally compatible with the platform, enabling efficient multi-vehicle charging without proportionally increasing control complexity
