Illuminable Emblem Light Conductor Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle emblems, particularly those serving as radomes or flap closure elements, are costly and complex to manufacture, and are not easily visible at night, making them inefficient for identification in darkness.
Innovation Solution
An illuminable emblem design featuring a housing with a transparent front cover and a rear-side housing base that encloses a light conductor with webs to efficiently direct light through transparent regions, minimizing unnecessary light dispersion and allowing for sharp, line-type illumination, while maintaining radar beam integrity through uniform filling of intermediate spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If an areal light conductor with lateral light coupling is used, then the emblem is visible in illuminated form, but manufacturing outlay and costs increase
Solution Approach 1:
The light conductor is segmented into web-like structures with light-conducting strips arranged in a grid pattern, replacing the areal light conductor design. This segmentation allows light to be conducted efficiently to visible regions while reducing material usage and manufacturing complexity
Solution Approach 2:
The front cover is designed with regionally differentiated transparency - transparent regions where light should emerge and non-transparent regions where light should not emerge. This local quality differentiation allows the light conductor to be simplified while maintaining proper illumination distribution
2Illumination intensity
If light is laterally coupled out of the light conductor towards the front plate, then the emblem becomes visible, but unnecessary light is conducted into non-visible regions and scattered
Solution Approach 1:
The front cover incorporates non-transparent regions that act as optical barriers, preventing light from being conducted into non-visible areas. The transparent regions are strategically positioned to allow light emergence only where needed, eliminating wasted light propagation
Solution Approach 2:
The light conductor is divided into discrete web-like strips that target specific illumination zones, preventing light from spreading into unnecessary regions. The segmented structure confines light propagation to intended paths
3Ease of manufacture
If the intermediate spaces between the webs are non-filled or covered, then production is simpler, but radar beam distortion increases
Solution Approach 1:
The intermediate spaces between the light-conducting webs are uniformly filled with radome material that has consistent electromagnetic properties. This homogeneous filling ensures uniform radar wave propagation while maintaining the simplified web-like light conductor structure
