Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the infrared camera is disposed at the front of the vehicle to monitor surroundings, then the monitoring coverage is improved, but the camera temperature exceeds the durability upper limit due to radiant heat from the internal combustion engine
Solution Approach 1:
The control unit preemptively shuts down the infrared camera when the vehicle stops and the engine temperature exceeds a predetermined threshold, preventing the camera from being exposed to excessive heat that would cause malfunction. This preliminary protective action avoids the need for reactive repairs and ensures the camera remains within safe operating temperature ranges.
2Reliability
If the camera is shut down to prevent overheating, then the camera protection is improved, but the monitoring function is interrupted
Solution Approach 1:
The system implements periodic monitoring of engine temperature and vehicle status, shutting down the infrared camera only during specific periods when the vehicle is stopped and engine temperature exceeds the threshold. When the vehicle resumes movement or engine temperature drops below the threshold, the camera automatically restarts, minimizing interruption to the monitoring function while providing necessary protection.
