Vehicle Light Module With Relative Optics Shift for Beam Steering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting modules require a structural component to move the entire lighting module, resulting in bulkiness and potential light leakage through gaps.
Innovation Solution
A vehicle lighting module with a system for lateral and vertical displacement of collectors and light sources relative to optical output elements, eliminating the need for a structural component to move the entire module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional bulb is used as a light source, then the bulb can be easily replaced, but the light guide element must be disconnected from the bulb holder, requiring additional space and complicating the housing structure
Solution Approach 1:
The bulb holder is integrated directly into the light guide element, merging two previously separate components. This integration eliminates the need for additional connection structures and space, allowing the bulb to be replaced by simply removing it from the integrated holder without disconnecting any light guide elements. The housing structure is thereby simplified while maintaining ease of bulb replacement.
2Device complexity
If the light guide element is designed as a single piece, then the housing structure is simplified, but the light guide element cannot be replaced separately from the housing
Solution Approach 1:
The light guide element is segmented into two functionally independent parts: the main light guide body and the integrated bulb holder. This segmentation allows the bulb holder to be removed from the light guide element, enabling bulb replacement without replacing the entire light guide assembly. The segmented design maintains structural simplicity while providing the versatility of separate component replacement.
3Ease of operation
If the bulb holder is integrated into the light guide element, then the bulb can be replaced without disconnecting the light guide, but the holder must be designed as a separate component requiring additional manufacturing steps
Solution Approach 1:
The bulb holder is merged with the light guide element to form an integrated assembly. This merging eliminates the need for separate connection structures and reduces the number of assembly steps required during manufacturing. The integrated design allows the bulb holder to be formed as part of the light guide element itself, simplifying both manufacturing and bulb replacement operations.
