Vehicle Lamp Bracket Segmentation for Optical Axis Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle lamp configurations that allow optical axis adjustment for multiple optical units are not compact due to the need for space to pivot individual units, making it difficult to achieve accurate optical axis alignment and a compact design simultaneously.
Innovation Solution
A vehicle lamp configuration that includes a main bracket pivotably supported to a lamp body, with a sub-bracket pivotably supported to the main bracket, allowing one side of the first optical unit and multiple second optical units to be directly supported to the main bracket and the other side supported via the sub-bracket, enabling collective optical axis adjustment and correction of deviations between units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If individual optical units are pivotably supported to the main bracket for optical axis adjustment, then optical axis alignment accuracy is improved, but the device size increases due to required pivoting space
Solution Approach 1:
The patent divides the optical units into two groups: first optical units directly supported to the main bracket, and second optical units supported via a sub-bracket. This segmentation allows the second optical units to be collectively adjusted without requiring individual pivoting spaces, resolving the contradiction between alignment accuracy and device size.
Solution Approach 2:
A sub-bracket is introduced as an intermediary component between the main bracket and the second optical units. This sub-bracket enables collective optical axis adjustment of multiple second optical units without requiring individual pivoting mechanisms for each unit, thereby reducing the overall device size while maintaining alignment accuracy.
2Productivity
If main bracket is pivotably supported to lamp body for collective optical axis adjustment, then adjustment efficiency is improved, but device complexity increases
Solution Approach 1:
The bracket system is segmented into a main bracket for collective adjustment and a sub-bracket for fine-tuning specific optical units. This segmentation allows efficient collective adjustment while managing complexity through functional division.
Solution Approach 2:
The main bracket serves multiple functions: supporting the first optical units directly and providing the pivot point for the sub-bracket that supports second optical units. This multi-functionality improves adjustment efficiency without proportionally increasing device complexity.

AI summary
The present disclosure provides a vehicle lamp including: a main bracket pivotably supported to a lamp body; and a sub-bracket pivotably supported to the main bracket. A first optical unit is supported directly to the main bracket, and three second optical units are supported to the main bracket via the sub-bracket. An optical axis adjustment for the first optical unit and the three second optical units is collectively performed by pivoting of the main bracket, and an optical axis deviation between the first optical unit and the three second optical units is corrected by pivoting of the sub-bracket.
