Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle position lamp uses fixed brightness, then the device complexity is reduced, but the adaptability to different environmental conditions deteriorates
Solution Approach 1:
The sensing unit detects ambient light conditions and provides feedback to the control module, which automatically adjusts the lighting member brightness accordingly. This closed-loop feedback mechanism enables the position lamp to adapt to different environmental conditions without requiring complex manual intervention systems.
Solution Approach 2:
The control assembly performs self-adjustment of brightness based on environmental conditions detected by the sensing unit. The system serves itself by automatically adapting to changing light conditions without external control, reducing the need for complex user interfaces or manual adjustment mechanisms.
2Adaptability or versatility
If the vehicle position lamp uses automatic brightness adjustment, then the adaptability to environmental conditions is improved, but the device complexity increases
Solution Approach 1:
The control assembly is segmented into distinct functional modules: a sensing unit for detecting ambient light conditions and a control module for processing the sensing signal and controlling brightness adjustment. This segmentation allows each module to perform its specific function efficiently while maintaining overall system manageability and reducing integration complexity.
3Reliability
If the vehicle position lamp maintains fixed brightness, then the manufacturing cost is reduced, but the warning effectiveness in dim environments deteriorates
Solution Approach 1:
The brightness parameter of the lighting member is dynamically changed based on ambient light conditions detected by the sensing unit. In dim environments, the control module increases the brightness parameter to enhance warning effectiveness, while in bright conditions, it reduces brightness to prevent glare and conserve energy.
