Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle headlight adjustment systems are complex, requiring many components and significant space, making installation difficult and limiting design options due to their complicated structure and large size.
Innovation Solution
The adjustment device employs a mechanical coupling system with rocker elements and pivot bearing points to allow simultaneous vertical and horizontal adjustment of optically relevant structural units, maintaining parallel axes and reducing the need for separate holders, using coupling elements that can change length and drive means for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional adjustment systems are used, then vertical and horizontal adjustment of light modules is achieved, but the system becomes complex with many individual components and complicated structure
Solution Approach 1:
The patent combines multiple adjustment functions (vertical and horizontal adjustment of multiple light modules) into a single integrated adjustment device. The coupling element mechanically links multiple structurally relevant units, allowing simultaneous adjustment of all units through a single adjustment element, thereby reducing system complexity while maintaining full adjustment capability.
Solution Approach 2:
The adjustment device is designed as a universal system that can adjust multiple different types of structurally relevant units (light modules with different optical axes and adjustment points) using the same mechanical coupling mechanism. This multi-functional approach eliminates the need for separate adjustment mechanisms for each light module.
2Ease of operation
If traditional adjustment systems with many components are used, then adjustment functionality is provided, but installation becomes more difficult and requires more time
Solution Approach 1:
Multiple adjustment functions are merged into a single integrated device that can be installed as one unit rather than assembling multiple separate components. The coupling element is designed to simultaneously engage with multiple structurally relevant units, allowing all adjustments to be made through a single installation process.
3Ease of operation
If traditional adjustment systems are used, then light module adjustment is achieved, but construction and pivoting space within the headlight is significantly increased
Solution Approach 1:
The adjustment mechanism is designed to operate within the existing compact headlight structure by nesting the adjustment movements within the available space. The coupling element allows pivoting movements to occur in a coordinated manner that minimizes the required construction space while still enabling full adjustment range for all light modules.
