A lidar cover with a transparent layer and a colored layer that includes low- and high-transmittance regions, allowing for optional color application and improved measurement light transmission while maintaining design flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional lidar cover with metallic luster or black color is used, then the lidar unit is protected, but the design flexibility is extremely low and the overall vehicle design is deteriorated
Solution Approach 1:
The cover is divided into multiple layers including a base layer and a colored layer, where each layer serves specific functions. The colored layer is further segmented into different transmittance regions to balance design flexibility and light transmission requirements.
Solution Approach 2:
Different regions of the colored layer are assigned different optical transmittance properties. The first region has higher transmittance for measurement light while the second region has lower transmittance, allowing localized optimization for both functionality and aesthetics.
2Adaptability or versatility
If a colored layer with uniform transmittance is used, then design flexibility is improved, but measurement light transmission is insufficient
Solution Approach 1:
The colored layer incorporates regions with different transmittance characteristics. The first region allows higher measurement light transmission while the second region provides lower transmission, enabling both aesthetic customization and functional performance within the same component.
Solution Approach 2:
The cover combines multiple materials with different optical properties in a layered structure. The base layer provides structural support while the colored layer adds aesthetic value and selective light transmission, creating a composite structure that satisfies multiple requirements simultaneously.
3Reliability
If the colored layer has high transmittance throughout, then measurement light transmission is improved, but the colored appearance is not clearly visible
Solution Approach 1:
The colored layer is designed with spatially varying transmittance: the first region has higher transmittance to ensure adequate measurement light passes through to the lidar sensor, while the second region has lower transmittance to provide sufficient color density for clear visual appearance.
Solution Approach 2:
The colored layer utilizes variations in color density and transmittance across different regions. This allows the cover to display a clear colored appearance in certain areas while maintaining adequate light transmission in other areas critical for lidar operation.
