Vehicle Taillight Bracket Assembly for Cavity Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle taillight assemblies face challenges in maintaining a secure and consistent fit of the lamp housing within the cavity defined by the vehicle body structure, due to variations in manufacturing and assembly conditions, leading to potential misalignment and a loose fit.
Innovation Solution
A bracket assembly comprising a first bracket supported to the vehicle strut structure, a second bracket fixed to the inboard facing side of the first bracket, and a third bracket positioned between the first bracket and the vehicle strut structure, which maintains a desired distance and shape of the cavity to ensure a snug fit of the lamp housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple single bracket structure is used to support the lamp housing, then the device complexity is reduced, but the manufacturing precision and fit consistency deteriorate due to variations in manufacturing and assembly conditions
Solution Approach 1:
The bracket structure is divided into multiple separate brackets (first bracket, second bracket, third bracket) that work together as an assembly. This segmentation allows each bracket to be manufactured and positioned independently, compensating for manufacturing variations and ensuring consistent lamp housing fit without requiring a single complex bracket design.
2Device complexity
If the lamp housing is directly supported to the vehicle strut structure, then the device complexity is reduced, but the reliability of the fit deteriorates leading to potential misalignment and loose fit
Solution Approach 1:
Multiple brackets are introduced as intermediary components between the vehicle strut structure and the lamp housing. These brackets act as mediators that provide precise positioning and secure attachment, ensuring reliable fit and preventing misalignment while maintaining a relatively simple overall support structure.
3Manufacturing precision
If a multi-bracket assembly is used to ensure secure fit and consistent positioning, then the manufacturing precision and reliability improve, but the device complexity increases
Solution Approach 1:
The bracket assembly is segmented into multiple functional brackets (first bracket supported to vehicle strut structure, second bracket fixed to first bracket, third bracket positioned between first bracket and vehicle strut structure). Each bracket performs a specific positioning function, and together they achieve precise lamp housing fit without requiring any single bracket to be overly complex.
Solution Approach 2:
The brackets are arranged in a nested configuration where the second bracket is fixed to the inboard facing side of the first bracket, and the third bracket is positioned between the first bracket and the vehicle strut structure. This nesting allows the brackets to work together in a compact arrangement, achieving precise positioning while minimizing overall complexity.

AI summary
A vehicle taillight assembly includes a first bracket and a second bracket. The first bracket is configured to be supported to a vehicle strut structure. The second bracket is fixed to the first bracket at an inboard facing side of the first bracket. The second bracket protrudes in an inboard facing direction towards the vehicle strut structure.
