Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging is implemented without precise position alignment, then charging convenience is improved, but charging efficiency deteriorates due to defective contact between pads
Solution Approach 1:
The system continuously monitors charging information (charging speed, charging amount, charging efficiency) from the BMS and compares it with reference data. When abnormal charging state is detected, the system provides feedback by transmitting control commands to the autonomous parking controller to correct the vehicle position, thereby maintaining efficient charging while preserving convenience
Solution Approach 2:
The patent replaces manual positioning and mechanical alignment procedures with an automated system that uses sensor data processing and autonomous parking control. The system automatically detects misalignment through charging parameter monitoring and executes position correction without driver intervention, substituting mechanical alignment operations with automated control systems
2Productivity
If autonomous parking function is added to correct vehicle position, then charging efficiency is improved, but device complexity increases
Solution Approach 1:
The system integrates multiple functions into existing vehicle components: the BMS serves both battery management and charging state monitoring, the autonomous parking controller handles both parking operations and position correction, and the communication module manages both data transmission and control commands. This multi-functionality reduces the need for dedicated components, thereby limiting the increase in device complexity while achieving improved charging efficiency
3Measurement precision
If real-time monitoring of charging information is implemented, then charging accuracy is improved, but loss of time increases due to continuous data processing
Solution Approach 1:
The system monitors charging information in real-time but only triggers position correction actions when abnormal charging state is detected through comparison with reference data. This partial action approach maintains measurement precision by continuous monitoring while avoiding unnecessary time consumption from continuous active correction, intervening only when needed
