Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional light source system is used, then the structure is simple, but the illumination uniformity and intensity distribution are insufficient for vehicle-mounted applications
Solution Approach 1:
The beam conversion element is divided into two distinct functional regions: a flat region for generating condensed light and a curved-surface region for generating diffused light. This segmentation allows each region to independently optimize its light conversion function, achieving both high illumination intensity and uniform distribution without requiring complex multi-component systems.
Solution Approach 2:
Different regions of the beam conversion element are assigned different surface geometries with specific optical properties. The flat region provides localized light condensation for high intensity, while the curved-surface region provides localized light diffusion for uniformity. This local differentiation of quality enables simultaneous optimization of both illumination intensity and uniformity within a single integrated component.
2Illumination intensity
If uniform illumination light is provided, then the light distribution is even, but the intensity is insufficient for vehicle-mounted applications
Solution Approach 1:
The beam conversion element segments the light conversion process into two parallel pathways: one through the flat region for condensed light (high intensity) and one through the curved-surface region for diffused light (uniform distribution). Both pathways operate simultaneously on the same input light, producing a combined output that achieves both high brightness and uniform distribution.
Solution Approach 2:
The patent merges the outputs of the flat region (condensed light) and curved-surface region (diffused light) to create a composite illumination pattern. This combining allows the system to achieve both high intensity from the condensed light component and uniform distribution from the diffused light component, resolving the contradiction between brightness and uniformity.
