Vehicle Headlight Bracket Segmentation for Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle headlight brackets require high strength and load-bearing capacity due to the distance between the center of gravity and the rotation axis, necessitating costly metal materials.
Innovation Solution
A supporting bracket design with a first rotary part that includes a long or short shaft coaxial with the rotation axis, allowing the bracket to rotate and reduce the load-bearing moment, enabling the use of lower-strength materials and incorporating a universal connection structure for vertical adjustment.

Engineering Contradiction Analysis
1Length of moving object
If the bracket is directly connected to the rotation axis with the center of gravity far away, then the light-emitting unit can be positioned effectively, but the load-bearing requirement for the bracket increases significantly
Solution Approach 1:
The bracket is divided into multiple components: a first bracket body connected to the rotation axis, a second bracket body supporting the light-emitting unit, and a connecting component linking them. This segmentation allows the center of gravity to be positioned away from the rotation axis while distributing the load across multiple structural elements, reducing the strength requirement for any single component.
2Device complexity
If the bracket is directly connected to the rotation axis, then the structure is simple, but the bracket must be manufactured with high-strength metal materials increasing cost
Solution Approach 1:
By segmenting the bracket into multiple components, each part can be manufactured separately with lower-strength, lower-cost materials. The connecting component uses a universal connection structure that simplifies assembly while maintaining structural integrity, reducing overall manufacturing complexity and cost.
Solution Approach 2:
The connecting component acts as an intermediary between the first bracket body and the second bracket body. This intermediary element enables the use of lighter, cheaper materials in the main bracket structures while still achieving the required load-bearing performance through the distributed connection system.
3Adaptability or versatility
If the bracket supports both high beam and low beam units simultaneously, then the lighting system is integrated, but the load-bearing moment on the bracket increases
Solution Approach 1:
The bracket system is segmented into a first bracket body for mounting to the rotation axis and a second bracket body for supporting light-emitting units. This segmentation allows multiple light-emitting units (high beam and low beam) to be positioned at different locations, creating integrated lighting while distributing gravitational and operational loads across the segmented structure, thereby reducing the load-bearing moment on any single component.
