Motor Vehicle Headlight Optical Assembly Adjustment System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustment systems for motor vehicle headlights require significant installation space and are complex, limiting the optimal arrangement of optical elements within the headlight housing, as they need to adjust both low-beam and high-beam light units simultaneously.
Innovation Solution
A dual-axis adjustment system for optical assemblies, featuring pairs of adjustment apparatuses that allow independent and synchronized movement of separate lighting modules, with connecting members to transfer movement between them, enabling efficient adjustment without the need for extensive installation space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional adjustment systems are used for both low-beam and high-beam light units, then both units can be adjusted simultaneously, but the installation space requirement increases and the structure becomes more complex
Solution Approach 1:
The patent combines the adjustment mechanisms of low-beam and high-beam light units into a unified adjustment system. The connecting member links the first and second adjustment apparatuses, allowing them to work together as an integrated system rather than separate mechanisms, thereby reducing overall structural complexity while maintaining simultaneous adjustment capability
Solution Approach 2:
The adjustment system is designed with universal functionality where the connecting member and adjustment apparatuses can serve multiple purposes: adjusting low-beam units, adjusting high-beam units, and enabling synchronized adjustment of both. This multi-functionality reduces the need for separate dedicated adjustment mechanisms for each light unit type
2Adaptability or versatility
If traditional adjustment systems are used for both low-beam and high-beam light units, then both units can be adjusted simultaneously, but the installation space requirement increases
Solution Approach 1:
The patent employs a nested arrangement where the connecting member integrates the adjustment apparatuses in a compact configuration. The first and second adjustment apparatuses are positioned and connected in a space-efficient manner, with components arranged to minimize the overall footprint within the headlight housing
Solution Approach 2:
The adjustment apparatuses are arranged along the longitudinal axis of the headlight housing rather than requiring lateral space. This dimensional reorganization allows the adjustment mechanisms to be positioned in the longitudinal direction,充分利用 the available space and reducing the lateral installation footprint
3Ease of operation
If independent adjustment apparatuses are used for each optical assembly, then independent adjustment is enabled, but the connection and synchronization mechanism becomes more complex
Solution Approach 1:
The connecting member serves as an intermediary element that mediates between the first and second adjustment apparatuses. It provides a simple mechanical connection that transfers adjustment movements while maintaining independent adjustability, avoiding the need for complex synchronization mechanisms or control systems

AI summary
The adjustment system comprises at least one pair of adjustment apparatuses. For each optical assembly, one adjustment apparatus is adapted to turn the optical assembly around the turning axis (α; β) independently of the other optical assembly. The adjustment system further comprises an additional adjustment apparatus connected to a first adjustment apparatus and adapted to transfer its movement to the movement of this adjustment apparatus; and a connecting member connected to the additional adjustment apparatus and to a second adjustment apparatus at the same time, and adapted to transfer the movement of the additional adjustment apparatus to the movement of the second adjustment apparatus (. If the additional adjustment apparatus is connected to the first adjustment apparatus and the connecting member is connected between the additional adjustment apparatus and the second adjustment apparatus, turning movement of one optical assembly will automatically induce a turning movement of the other optical assembly.
