Removable Vehicle Lighting Assembly for Flexible Optical Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting assemblies are costly to replace due to fixed components like spherical mirrors and converging lenses, requiring complete repositioning during re-styling or damage, and lack flexibility in light orientation and dimension adjustment without compromising energy efficiency.
Innovation Solution
A lighting assembly with a frame-mounted optical assembly and lens that can be removed independently from the vehicle body, allowing adjustable mirrors and lenses to maintain light orientation and flexibility, and enabling easy replacement or repositioning without affecting the optical fiber and lens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spherical mirrors and converging lenses are fixed to the light guide, then the lighting assembly provides stable light reflection and refraction, but complete replacement of components is required during damage or re-styling, increasing maintenance costs
Solution Approach 1:
The lighting assembly is divided into separate functional modules: the light guide remains fixed to the vehicle body, while the spherical mirror and converging lens are mounted on a frame that can be independently removed. This segmentation allows the optical components to be replaced or adjusted without replacing the entire lighting assembly, reducing maintenance costs while preserving optical stability.
2Reliability
If spherical mirrors and converging lenses are fixed to the light guide, then the lighting assembly maintains stable optical performance, but repositioning during re-styling requires complete repositioning of the light guide, increasing complexity and cost
Solution Approach 1:
The lighting system is segmented into a fixed light guide portion and a removable frame portion containing the optical components. During re-styling, only the frame with mirrors and lenses needs to be repositioned or replaced, while the light guide remains in place, significantly reducing repositioning complexity.
Solution Approach 2:
The frame mounting structure is designed as a universal interface that can accommodate different configurations of mirrors and lenses while maintaining compatibility with the fixed light guide. This allows flexible repositioning and reconfiguration during vehicle re-styling without requiring custom integration work.
3Device complexity
If the lighting assembly uses fixed optical components, then the structure is simple, but flexibility in adjusting light orientation and distribution is limited
Solution Approach 1:
The optical components (spherical mirror and converging lens) are mounted on a frame that allows dynamic adjustment of their positions and orientations. This enables flexible adjustment of light orientation and distribution in horizontal and vertical planes while maintaining a relatively simple overall structure through modular design.
Solution Approach 2:
The frame structure provides additional degrees of freedom for positioning the optical components, allowing adjustment in multiple dimensions (horizontal and vertical planes). This enables versatile light orientation control without significantly increasing structural complexity.
4Device complexity
If the lighting assembly uses traditional fixed components, then the design is straightforward, but the overall dimensions cannot be reduced without compromising functionality
Solution Approach 1:
The optical components (mirrors and lenses) are nested within a compact frame structure that integrates multiple functions in a space-efficient manner. This nesting approach reduces the overall dimensions of the lighting assembly while maintaining all necessary optical functions and adjustment capabilities.
