Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle lighting and signaling devices are not suitable for displaying variable color and geometry lighting, and their fixed mounting locations do not align with current and future aesthetic and functional requirements.
Innovation Solution
A motor vehicle bodywork element with a wall featuring light diffusion zones on one face and light occultation zones on the other, separated by intermediate spaces forming opaque blocks connected by bridges, using a translucent layer and RGB LEDs controlled independently for dynamic lighting signatures, allowing for variable and adaptive lighting patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional lighting devices with isolated light sources and transparent walls are used, then lighting function is achieved, but aesthetic integration and variable lighting patterns are limited
Solution Approach 1:
The wall is segmented into multiple diffusion zones separated by intermediate spaces, with opaque blocks positioned at specific locations. This segmentation allows independent control of light diffusion in different zones, enabling variable lighting patterns and signatures while maintaining a unified structural approach
Solution Approach 2:
The wall structure serves multiple functions simultaneously: it provides mechanical enclosure, enables light diffusion through translucent zones, creates light occultation through opaque blocks, and facilitates variable lighting patterns through the arrangement of diffusion zones and intermediate spaces. This multi-functionality reduces the need for separate components
2Shape
If lighting devices are integrated into bodywork profiles, then aesthetic integration is improved, but mounting location flexibility is reduced
Solution Approach 1:
The wall structure incorporates local variations in light diffusion and occultation properties through strategically positioned opaque blocks and diffusion zones. This allows the same basic structure to be adapted to different mounting locations and bodywork profiles while maintaining aesthetic integration and functional performance
3Manufacturing precision
If opaque blocks are used to create occultation zones, then light signaling precision is improved, but manufacturing complexity increases
Solution Approach 1:
The wall is constructed as a composite structure combining translucent material with integrated opaque blocks. This composite approach allows precise positioning of occultation zones while maintaining manufacturability through techniques such as injection molding with inserts or post-molding attachment of opaque elements

Implementation Method 1
a wall (1) having, on a first face thereof, zones (11) for diffusing light emitted by at least one light source
Implementation Method 2
said wall further having, on its second face, zones (12) for occulting light; characterized in that said occultation zones are separated by intermediate spaces forming said light diffusion zones
Implementation Method 3
These light sources are so-called red green blue (RGB) LEDs, each controlled independently by a microprocessor so as to create a light signature
