Roof Opening Bracket Structure for Uniform Sunroof Edge Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sunroof systems in vehicles lack effective lighting solutions that can provide uniform illumination across the sunroof area, including corners, and are limited in adjusting radiation patterns and lengths, which restricts their application in enhancing interior ambiance and visibility.
Innovation Solution
An injection bracket device with an opening bracket and a mounting guide is injection molded to mount a lighting module along the edge of a headliner opening, allowing for uniform light radiation in all directions, including corners, and enabling adjustment of radiation length and pattern by modifying the structure of the opening bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional sunroof system is used, then the vehicle provides ventilation and openness during daytime, but it fails to provide effective lighting and ambiance during nighttime or adverse weather conditions
Solution Approach 1:
The sunroof system is enhanced by integrating a lighting module that can provide both daytime visibility (through the glass structure) and nighttime illumination (through LED lights). The bracket device enables the lighting module to be mounted in a way that serves multiple functions: ambient lighting, reading light, and decorative purposes, making the sunroof system adaptable to various indoor and outdoor situations.
2Illumination intensity
If ambient lighting is installed around the sunroof glass, then nighttime visibility and ambiance are improved, but the uniformity of light radiation including corners is compromised
Solution Approach 1:
The mounting guide is designed with specific geometric features including angled surfaces and extended portions that position the lighting module at precise angles relative to the sunroof opening. This local geometric customization ensures that light is radiated uniformly across the entire sunroof area, including corners, by directing light from strategically positioned LED sources at optimized angles.
3Ease of manufacture
If a fixed lighting module structure is used, then installation is simplified, but the ability to adjust radiation length and pattern is lost
Solution Approach 1:
The mounting guide incorporates adjustable elements such as movable clamps or repositionable mounting portions that allow the lighting module to be positioned at different locations and angles along the sunroof opening. This dynamic positioning capability enables adjustment of radiation length and pattern while maintaining a relatively simple overall bracket structure that is easy to manufacture and install.
