Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the vehicle drives past the parking space at usual road traffic speed to quickly identify parking spaces, then productivity is improved, but measurement precision of parking space boundaries deteriorates
Solution Approach 1:
The system performs preliminary rough measurement of parking space boundaries while the vehicle is moving at normal speed using available sensors. This preliminary action allows quick identification of potential parking spaces without requiring the vehicle to slow down specifically for measurement, thereby maintaining productivity while establishing initial boundary estimates.
Solution Approach 2:
The system provides feedback to the driver about the reliability of boundary detection through visual indicators (line thickness, color coding). This feedback mechanism allows the driver to understand measurement uncertainty and adjust their parking maneuver accordingly, compensating for reduced measurement precision during high-speed passes.
2Measurement precision
If multiple measuring systems are used to improve measurement precision of parking space boundaries, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system uses existing multi-functional sensors already present in the vehicle (radar for collision warning, ultrasonic sensors for parking assistance) to perform multiple functions including parking space boundary detection. This approach improves measurement precision without significantly increasing device complexity, as the same hardware serves multiple purposes.
Solution Approach 2:
The system combines data from multiple different sensor types (radar, ultrasonic, optical) to create a composite measurement result. By fusing information from heterogeneous sensing systems, the achievement superior measurement precision leverages the complementary strengths of each sensor type while avoiding the need for any single complex sensor system.
3Reliability
If the system provides detailed information about measurement reliability and boundary detection quality, then reliability of the parking process is improved, but loss of information increases due to additional data processing and display requirements
Solution Approach 1:
The system uses color coding (e.g., green, yellow, red) to indicate measurement reliability and boundary detection quality. This visual encoding conveys complex reliability information in an intuitive, easily interpretable format that requires minimal processing overhead while significantly improving driver confidence and understanding of detection accuracy.
Solution Approach 2:
The system provides selective information about measurement reliability rather than overwhelming the driver with all possible data. By displaying only the most critical reliability indicators (such as detection confidence levels and boundary uncertainty), the system improves reliability perception without the excessive information processing burden of presenting all available measurement data.
