Vehicle Headlamp Double Pivot Rocker Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle headlamps with multiple light sources face misalignment and labor-intensive adjustment challenges due to the need for individual adjustment of each beam, leading to inefficiencies in focusing multiple beams.
Innovation Solution
A double pivot rocker mechanism is introduced, allowing simultaneous adjustment of multiple lamp components by mounting them with equal distances to a stationary and floating pivot bearing, ensuring equal displacement and alignment of both components when actuated, thus eliminating misalignment and labor issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual adjustment of each beam is used, then each beam can be adjusted independently, but misalignment of beams occurs and considerable man-power is required
Solution Approach 1:
The patent combines multiple adjustment operations into a single unified mechanism. The adjustable support structure allows simultaneous adjustment of multiple lamp components (headlamp and fog lamp) through one operational action, merging what were previously separate adjustment procedures into a single coordinated system that maintains proper beam alignment while reducing manual effort
Solution Approach 2:
The adjustable support structure serves multiple functions: it supports both the headlamp and fog lamp components, provides simultaneous adjustment capability for both beams, and maintains alignment relationships between multiple light sources. This multi-functional design eliminates the need for separate adjustment mechanisms for each beam
2Measurement precision
If multiple lamp components are adjusted individually, then each component can be focused separately, but the adjustment process becomes labor-intensive and time-consuming
Solution Approach 1:
The patent establishes predetermined geometric relationships and alignment features in the adjustable support structure during manufacturing. The support structure is pre-configured with appropriate angles, distances, and mounting positions that ensure proper beam focusing and alignment, eliminating the need for time-consuming field adjustments while maintaining precise focusing capability
3Adaptability or versatility
If separate adjustment mechanisms are used for each beam, then individual beam control is achieved, but device complexity increases
Solution Approach 1:
The adjustable support structure is designed as a universal mounting system that can accommodate multiple types of lamp components (headlamp, fog lamp, etc.) while providing coordinated adjustment for all of them through a single mechanism, reducing overall system complexity while maintaining adaptability
Solution Approach 2:
The support structure is segmented into adjustable sections that can move independently relative to each other, allowing flexible positioning of different lamp components while being controlled by a unified adjustment mechanism, thus maintaining control flexibility without increasing overall device complexity

AI summary
A vehicle headlamp (10) has first and second lamp components (12, 14) mounted in a housing (16) having a wall (18). The first and second components (12, 14) are simultaneously adjustable from a double pivot rocker (20), the double pivot rocker (20) being mounted to the wall (18) by a stationary pivot bearing (21). The first and second lamp components (12, 14) each have a fixed pivot bearing (22, 24) fixed to the wall (18) and a floating pivot bearing (26, 28) fixed to the double pivot rocker (20). The first and second components (12, 14) can be reflectors positioned in a vertical array.
