Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple LEDs are used to light up a wide area, then the lighting coverage is improved, but the cost and volume of the vehicle are increased
Solution Approach 1:
The patent combines multiple lighting functions into a single projection optical system. Instead of using multiple separate LED units to illuminate different areas, one projection optical system with a rotatable reflection part integrates the functionality of multiple LEDs, reducing component count while maintaining wide-area lighting coverage.
Solution Approach 2:
The reflection part is designed to be rotatable, allowing dynamic adjustment of the lighting area. By rotating the reflection part, the system can change which areas are illuminated without adding more physical light sources, enabling flexible lighting coverage adaptation.
2Area of stationary object
If multiple LEDs are used to light up a wide area, then the lighting coverage is improved, but the vehicle weight is increased
Solution Approach 1:
The patent merges the function of multiple heavy LED components into a single projection optical system with a reflection part. This consolidation reduces the overall weight while achieving the same wide-area lighting effect through optical design rather than multiple light sources.
3Adaptability or versatility
If the reflection part is rotated to adjust lighting area, then the adaptability is improved, but the ease of operation changes
Solution Approach 1:
The reflection part is designed to be rotatable, allowing dynamic adjustment of the lighting area. By rotating the reflection part, the system can change which areas are illuminated without adding more physical light sources, enabling flexible lighting coverage adaptation.
