Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If uniform light output is used across the light distribution area, then the lamp structure is simple and easy to manufacture, but precise control of light output and resolution cannot be achieved
Solution Approach 1:
The light distribution area is divided into multiple control regions, with different resolution levels assigned to different regions. The processor controls the lamp module to output light at different resolutions in different regions, enabling precise light control where needed while maintaining simplicity in other areas.
Solution Approach 2:
Different resolution levels are applied to different regions of the light distribution area based on local requirements. High resolution is applied to regions requiring precise light control (such as areas with objects detected by the interface unit), while lower resolution is used in regions where precise control is not necessary, optimizing both control precision and system complexity.
2Illumination intensity
If high resolution light output is used throughout the entire light distribution area, then visibility and information transmission are maximized, but energy consumption increases
Solution Approach 1:
High resolution light output is applied only to partial regions where objects are detected or where precise light control is needed, rather than uniformly across the entire light distribution area. The processor receives object information from the interface unit and dynamically adjusts the resolution level in different regions, reducing energy consumption while maintaining visibility quality where necessary.
3Adaptability or versatility
If fixed resolution light output is used, then the lamp system is simple to operate, but adaptability to different driving situations is limited
Solution Approach 1:
The lamp system dynamically adjusts the resolution of light output in different regions based on driving situation information received by the interface unit. The processor automatically modifies the light distribution pattern in real-time according to detected objects and environmental conditions, providing adaptability without requiring manual operation complexity.
Solution Approach 2:
The interface unit receives information about objects and driving situations, providing feedback to the processor. The processor uses this feedback to automatically adjust the light output resolution and distribution pattern, enabling the system to adapt to different driving situations while maintaining ease of operation through automatic control.
