Pivotable Light Module Articulation for Vehicle Headlamp Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle illuminating devices face complexity in adjusting light modules relative to each other, requiring intricate mountings and slide guides, which complicates achieving optimal and legally compliant light exposure.
Innovation Solution
A supporting body with pivotable light modules, an articulation mechanism, and prestressing devices allows for adjustable light modules to be easily aligned, enabling independent pivoting about multiple axes for precise light distribution adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If complex mountings and slide guides with ball joint connections are used to adjust light modules, then the light modules can be adjusted relative to one another, but the device complexity increases
Solution Approach 1:
The adjustment system is segmented into independent pivotable light modules, each adjustable about specific axes through articulations. This allows individual module adjustment without requiring complex interconnected mounting systems, reducing overall device complexity while maintaining adjustability.
Solution Approach 2:
The light modules are designed to be dynamically adjustable through pivotable articulations rather than fixed mountings. Each module can be independently positioned and locked, providing ease of operation without requiring complex slide guides or ball joint connections throughout the entire mounting system.
2Manufacturing precision
If multiple adjusting devices are provided for independent adjustment of light modules about multiple axes, then the light exposure can be precisely adjusted to meet legal requirements, but the device complexity increases
Solution Approach 1:
The articulation mechanism serves multiple functions simultaneously - it provides pivotable connections for adjustment, structural support for the light module, and positioning reference. This multi-functionality reduces the need for separate adjusting devices for each degree of freedom, achieving precise light exposure adjustment without proportionally increasing device complexity.
Solution Approach 2:
The articulation structure inherently provides the adjustment capability through its geometric design and pivot points. The system uses its own structural elements (articulations and mounting bodies) to enable adjustment rather than requiring additional external adjusting mechanisms, thereby achieving precision without excessive complexity.
