Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lamps require a large volume to ensure sufficient spreading of light beams without an air gap, leading to reduced space efficiency.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If an air gap is formed between the lens and the light source to sufficiently spread the light beam, then the light beam can be uniformly output from the lens, but the lamp volume increases and space efficiency is degraded
Solution Approach 1:
The patent introduces an inner lens as an intermediary optical element between the light source and outer lens. This inner lens includes a reflective area that reflects light beams and an output area that outputs reflected light, enabling uniform light distribution without requiring a large air gap. The inner lens acts as a mediator that achieves light uniformity while maintaining compact dimensions.
Solution Approach 2:
The patent utilizes the third dimension by positioning the output area of the inner lens closer to the first direction (light output direction) than the reflective area, creating a three-dimensional optical path arrangement. This dimensional arrangement allows light to be reflected and redirected through multiple paths within a compact volume, achieving uniform output without increasing overall lamp size.
2Illumination intensity
If the lens and light source are arranged to be spaced a predetermined distance to form an air gap, then light beam spreading is achieved, but the lamp requires large volume
Solution Approach 1:
The patent merges the functions of light reflection, redirection, and uniform distribution into a single inner lens component. By combining multiple optical functions into one integrated element, the design achieves effective light spreading without requiring separate components spaced apart, thereby reducing overall lamp volume while maintaining light beam spreading performance.
Solution Approach 2:
The inner lens is nested within the optical system between the light source and outer lens, creating a compact nested arrangement. This nesting allows the light reflection and redirection functionality to be embedded within the existing optical path structure, eliminating the need for additional space that would be required if separate reflection and diffusion components were used.
