Vehicle Headlamp Adjustment Device with Dual-Axis Pivoting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headlight adjustment devices are complex, expensive, and require cumbersome mechanisms for adjusting optically relevant components, often necessitating separate adjustment elements for horizontal and vertical axes, making them difficult to use.
Innovation Solution
A compact adjustment device using a main joint for pivoting about two intersecting axes, with a pivoting element articulated on a sliding element via a sliding element joint, allowing independent adjustment using two turning screws, and incorporating a ball joint for mounting the support frame to the headlight housing, eliminating the need for complicated mechanisms like worm gears.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate adjustment elements are used for horizontal and vertical axes, then the adjustment function is achieved, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent combines two separate adjustment mechanisms into a single integrated device. The support frame is pivotably mounted on the headlight housing via one adjustment device that simultaneously provides both horizontal and vertical adjustment capabilities through integrated adjustment elements, eliminating the need for separate spatially distributed adjustment mechanisms.
Solution Approach 2:
The single adjustment device performs multiple functions by providing both horizontal and vertical adjustment capabilities through its integrated design. The adjustment elements are configured to enable pivoting about both horizontal and vertical axes intersecting at the main joint, making one device universal for both adjustment directions.
2Ease of manufacture
If complicated mechanisms with deflections are used, then the adjustment function is achieved, but the manufacturing cost increases
Solution Approach 1:
The patent extracts and eliminates unnecessary complicated mechanisms such as worm gears and deflection elements from the adjustment system. By using a simplified pivotable mounting with direct adjustment elements, the design removes extraneous components that increase manufacturing cost and complexity while maintaining the essential adjustment function.
Solution Approach 2:
Instead of using complex mechanisms with multiple deflections to achieve adjustment, the patent inverts the approach by using a simple pivotable support frame mounted directly on the headlight housing. The adjustment is achieved through direct pivoting action rather than through complicated intermediate mechanisms.
