Vehicle Lighting Optical Modules on Common Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting and signaling devices for motor vehicles face challenges in manufacturing costs and adjustment complexities due to the lack of a common frame of reference between optical modules, leading to inadequate superposition of light beams and increased manufacturing costs.
Innovation Solution
The integration of optical modules on a common support, such as a rigid or flexible substrate with conductive tracks, allows for direct alignment and simplifies adjustments, eliminating the need for additional costly steps by ensuring the first light beam's cut-off line is positioned below the second light beam's cut-off edge, which reduces manufacturing costs and improves lighting efficiency.

Engineering Contradiction Analysis
1Ease of manufacture
If optical modules are mounted on separate supports, then manufacturing flexibility is improved, but beam superposition precision deteriorates and adjustment complexity increases
Solution Approach 1:
The patent merges multiple optical modules onto a single common support structure, eliminating the need for separate supports. This integration ensures precise beam superposition by providing a unified reference frame, while the modular optical components remain manufacturable using standard processes. The common support includes integrated positioning features that automatically align optical modules during assembly.
2Adaptability or versatility
If optical modules are mounted on separate supports, then component independence is improved, but adjustment steps and manufacturing cost increase
Solution Approach 1:
The patent combines multiple optical modules on a single support structure, reducing the number of adjustment steps required. The common support includes integrated positioning features and alignment references that enable automatic or simplified adjustment during assembly, eliminating the need for multiple separate adjustment procedures while maintaining optical module functionality.
3Ease of manufacture

AI summary
The device (11) has two optical modules (12, 12 ', 13, 13') respectively generating light beams having, in projection on a screen perpendicular to an optical axis, a plane cutting line and a cutting edge, where the cutting edge comprises two branches forming non-zero angle between the branches. The optical modules are arranged relative to one another such that the light beams are partially superimposed in projection on the screen. The optical modules assembled on a common support (17), where each module includes a light source (51) e.g. single-chip or multi-chip LED.
