Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical connection status is monitored continuously in real-time during vehicle operation, then safety and reliability are improved, but energy consumption and system complexity increase
Solution Approach 1:
The system performs electrical connection status detection at specific intervals or triggers (such as when reverse gear is engaged, or at predetermined times during operation) rather than continuous monitoring. The controller is configured to detect connection status based on electrical signals from the trailer, and this detection occurs periodically or event-driven, reducing overall energy consumption while maintaining safety.
Solution Approach 2:
The system performs preliminary detection of the trailer's presence and electrical connection status before certain vehicle operations (such as reversing or moving forward). This allows the system to prepare safety checks in advance, ensuring connection integrity is verified before critical maneuvers without requiring constant monitoring during all vehicle operations.
2Measurement precision
If multiple detection methods (electrical signals, ultrasonic sensors, cameras) are used to verify trailer presence and connection status, then measurement precision and reliability are improved, but device complexity increases
Solution Approach 1:
The system combines multiple detection methods (electrical connection status detection, ultrasonic sensor detection, and camera-based detection) into a unified trailer detection system. The controller integrates signals from these different sources to comprehensively determine trailer presence and connection status, achieving high measurement precision through multi-modal verification while managing system complexity through centralized control logic.
Solution Approach 2:
The detection system is designed with multi-functionality, where a single controller performs multiple detection tasks: monitoring electrical connection status, processing ultrasonic sensor data for distance measurement, and analyzing camera images for visual verification. This universal approach allows one system to fulfill multiple detection functions, improving accuracy without proportionally increasing overall system complexity.
3Reliability
If the system detects forward movement and triggers notification based on electrical connection status, then safety is improved, but loss of time in response and notification increases
Solution Approach 1:
The system detects electrical connection status and trailer presence in advance before forward movement occurs or during the movement process. By having the detection system already active and monitoring connection status preliminarily, the system can immediately trigger safety notifications when forward movement is detected, minimizing response time while maintaining safety.
Solution Approach 2:
The system implements real-time feedback by continuously monitoring electrical connection status and comparing it with vehicle movement status. When forward movement is detected, the system immediately processes the connection status information and provides feedback through safety notifications, ensuring timely response without significant delay through efficient real-time processing and feedback loops.
