Vehicle Headlight Light Module Anti-Vibration Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting and signaling devices in vehicle headlamps fail to ensure correct positioning and anti-vibration fixing of light guides, leading to potential changes in light distribution due to vibrations during vehicle travel, affecting photometric performance.
Innovation Solution
A light module with a support system featuring first and second attachment means, including clips and hooking teeth, that securely positions and fixes light guides at the headlamp, utilizing guide positioning means like gutters and shafts with complementary shapes to maintain precise placement and prevent vibration-induced displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If simple lighting and signaling supports are used in headlamps, then device complexity is reduced, but positioning precision and anti-vibration fixing of light guides deteriorate
Solution Approach 1:
The support system is divided into multiple functional components: guide positioning means (gutters) for lateral positioning, first attachment means (clips) for securing one end, and second attachment means (hooking teeth) for securing the other end. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity.
Solution Approach 2:
The support structure acts as an intermediary element between the light guides and the headlamp housing. It provides a standardized interface that ensures precise positioning and secure fixation without requiring complex direct mounting mechanisms, thereby simplifying the overall device while improving positioning precision.
2Ease of manufacture
If conventional fixing means are used for light guides, then ease of manufacture is improved, but reliability against vibration-induced displacement deteriorates
Solution Approach 1:
The support system is pre-configured with guide positioning means, clips, and hooking teeth during manufacturing. This preliminary arrangement ensures that when light guides are assembled, they are automatically positioned correctly and secured reliably without requiring complex adjustment procedures, thus maintaining ease of manufacture while improving vibration resistance.
Solution Approach 2:
The fixing means incorporate elastic elements (clips and hooking teeth) that can dynamically adapt to vibration forces. These elements maintain continuous contact and securing force on the light guides during vehicle operation, ensuring reliable anti-vibration fixation while keeping the assembly process simple.
