Vehicle Headlamp Module Adjustment With Compact Coupled Pivot Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional headlamp lighting systems with multiple luminous modules face challenges in adjusting the modules independently or simultaneously due to bulky and complex coupling means, which are not suitable for a large number of modules and are constrained by aesthetic and spatial considerations.
Innovation Solution
A lighting device for a headlamp comprising a main mounting plate with separate luminous modules mounted on intermediate supports that pivot about specific axes. The device includes first adjustment means for simultaneous vertical movement of the modules and second adjustment means for tilting individual modules about their pivot axes, with coupling members allowing simultaneous movement of modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If coupling means are used to adjust multiple luminous modules simultaneously or independently, then the adjustment functionality is improved, but the device complexity and footprint increase
Solution Approach 1:
The headlamp is divided into multiple independent luminous modules (211a, 211b, 211c), each with its own intermediate support (217a, 217b, 217c) and pivot axis (2200a, 2200b, 2200c). This segmentation allows each module to be adjusted independently while maintaining overall system functionality, reducing the complexity of coupling mechanisms compared to a unified adjustment system.
Solution Approach 2:
The patent introduces a hierarchical adjustment system with two dimensions: first adjustment means (13) providing global vertical adjustment about a first adjustment axis (1000), and second adjustment means (23) providing local tilting about module-specific pivot axes (2000). This multi-dimensional approach enables complex adjustment functionality without requiring complex coupling between modules.
2Adaptability or versatility
If coupling means are used to connect multiple luminous modules, then simultaneous adjustment is enabled, but the footprint and space requirements increase
Solution Approach 1:
The main mounting plate (9) serves multiple functions: it supports all intermediate supports (17), provides the first adjustment axis (1000) for global vertical movement, and acts as the structural base for the entire lighting device. This universal component reduces the need for additional coupling structures, minimizing footprint while enabling simultaneous adjustment of multiple modules.
Solution Approach 2:
The patent utilizes vertical stacking of luminous modules (211a, 211b, 211c) along the vertical direction, with pivot axes (2200a, 2200b, 2200c) arranged at different heights. This three-dimensional arrangement allows modules to be coupled and adjusted simultaneously without increasing the horizontal footprint, as adjustments occur primarily in the vertical dimension.
3Measurement precision
If independent adjustment of each luminous module is implemented, then adjustment precision is improved, but the device complexity increases
Solution Approach 1:
Each luminous module (211a, 211b, 211c) is equipped with its own intermediate support (217a, 217b, 217c) and pivot axis (2200a, 2200b, 2200c), enabling independent adjustment. This segmentation provides precise control over each module's orientation while maintaining manageable complexity through modular design, where each module's adjustment mechanism is identical and can be standardized.
Solution Approach 2:
The second adjustment means (23) is designed to simultaneously control the tilting of multiple modules (211a, 211b, 211c) about their respective pivot axes (2200a, 2200b, 2200c) through a unified mechanism. This universal adjustment system provides precise independent control for each module while reducing overall complexity by using a single control system rather than separate mechanisms for each module.

AI summary
A lighting device for a headlamp of a vehicle includes a main mounting plate, and a plurality of separate luminous modules each mounted on an intermediate support. Each intermediate support is movably mounted relative to the main mounting plate about a pivot axis specific to the module in question. The device further includes at least one member for coupling an assembly or sub-assembly of two modules of the plurality of modules, connecting the intermediate supports bearing the two modules so as to allow the simultaneous movement of said two modules.
