Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic charging is enabled when inductive chargers are within a charging zone, then charging convenience is improved, but charging usage calculation precision deteriorates
Solution Approach 1:
The system continuously monitors multiple parameters including vehicle position relative to charging zones, inductive charger status, and charging current flow. This feedback mechanism enables precise tracking of actual charging events and usage amounts, resolving the contradiction by providing both automatic operation and accurate measurement through real-time data collection and processing.
2Ease of operation
If wireless charging usage is determined automatically, then operational simplicity is improved, but measurement accuracy deteriorates
Solution Approach 1:
The system employs continuous feedback monitoring of vehicle position, charging zone boundaries, inductive charger activation status, and actual charging current. This multi-parameter feedback enables automatic determination while maintaining high measurement accuracy through real-time verification of charging events.
Solution Approach 2:
The system monitors more parameters than strictly necessary for basic charging activation, including detailed position tracking, charger status, and charging current measurement. This excessive monitoring ensures accurate usage calculation while maintaining automatic operation, resolving the contradiction between simplicity and precision.
3Measurement precision
If multiple parameters are monitored for charging determination, then charging usage precision is improved, but system complexity increases
Solution Approach 1:
The system uses a multi-functional processor that handles diverse tasks including position calculation, charging zone determination, usage amount calculation, and payment processing. This universal component approach achieves high measurement precision through multiple monitored parameters while controlling overall system complexity by consolidating functions into a single processing unit.
