Solution Overview
Problem
Existing lighting devices for motor vehicles face challenges in aligning partial light distributions optimally, particularly in horizontal and vertical directions, to achieve a legally compliant and optimal overall light image.
Innovation Solution
The solution involves pivotable reflectors mounted on reflector holders, which can be adjusted about vertical and horizontal axes, allowing for precise alignment of light segments through adjustable reflector blocks and fixing mechanisms, enabling optimal alignment of light distributions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If reflectors are made fixed and integrated with mounting body, then device complexity is reduced, but alignment precision of partial light distributions deteriorates
Solution Approach 1:
The reflector is divided into two independent components: a reflector holder that mounts to the mounting body, and a separate reflector element that can be adjusted relative to the holder. This segmentation allows the alignment function to be separated from the mounting structure, enabling precise adjustment without increasing overall structural complexity.
Solution Approach 2:
The reflector holder is designed with pivotability about vertical and horizontal axes, transforming a static fixed structure into a dynamic adjustable one. This allows the reflector to be positioned at different angles to achieve optimal alignment of partial light distributions, while the fixing means provide stable fixation once alignment is achieved.
2Manufacturing precision
If multiple adjustment mechanisms are added for reflector alignment, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The reflector holder serves multiple functions: it provides structural support for the reflector, enables pivoting about vertical and horizontal axes for alignment, and incorporates fixing means for securing the reflector in the desired position. This multi-functionality achieves precise alignment capability without adding separate adjustment mechanisms, thereby avoiding increased structural complexity.
3Adaptability or versatility
If reflector is made adjustable relative to mounting body, then adaptability of light distribution is improved, but device complexity increases
Solution Approach 1:
The adjustment and fixation functions are merged into a single integrated reflector holder assembly. The holder combines the pivot mechanisms for vertical and horizontal adjustment with the fixing means, allowing the reflector to be adaptively positioned and then securely fixed. This merging approach provides high adaptability while minimizing structural complexity by avoiding separate adjustment and fixation systems.
