Vehicle Light Module with Relative Optics Movement for Beam Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminous modules for vehicles require a structural component to move the entire module for adjusting light beam direction, resulting in bulkiness and potential light leakage through clearances.
Innovation Solution
A luminous module with a system for lateral and vertical relative movement of collectors and light sources relative to exit optical elements, allowing independent adjustment of the light beam without moving the entire module, using a system comprising pivot connections, ball joints, and actuators to achieve lateral and vertical travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire luminous module is moved to adjust the light beam, then lateral and vertical travel are achieved, but the structural component becomes bulky and clearances create light leakage
Solution Approach 1:
The patent divides the luminous module into two separate movable parts: the optical assembly (collector and light source) and the exit optical element. Only the optical assembly is moved to adjust the light beam, while the exit optical element remains stationary. This segmentation eliminates the need for a bulky structural component that would otherwise need to move the entire module, and prevents light leakage through clearances between moving parts and styling components.
2Ease of operation
If the entire luminous module is moved to adjust the light beam, then beam positioning is achieved, but the module becomes bulky and heavy
Solution Approach 1:
The patent segments the luminous module so that only the optical assembly (collector and light source) is moved for beam positioning, while the exit optical element and styling components remain stationary. This reduces the weight of the moving object significantly compared to moving the entire module, as the exit optical element and styling components constitute a substantial portion of the total weight.
3Ease of operation
If clearances are provided for moving the entire module, then movement is enabled, but light leaks through these clearances
Solution Approach 1:
The patent segments the movement function so that only the optical assembly moves, while the exit optical element and styling components remain fixed. This eliminates clearances between moving parts and styling components, preventing light leakage. The stationary exit optical element maintains tight sealing with the styling components, while the optical assembly moves independently within its own space.
4Ease of operation
If all components are moved for lateral and vertical travel, then beam adjustment is achieved, but device complexity increases
Solution Approach 1:
The patent simplifies the device by segmenting the movement function: only the optical assembly (collector and light source) is moved using a simple actuating mechanism, while the exit optical element remains stationary. This eliminates the need for complex structural components that would be required to move the entire module, reducing overall device complexity while maintaining full beam adjustment capability.
