Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light source modules for vehicle sunroofs are costly due to the need for custom, high-precision curved light-guiding strips that are not universally applicable and require separate development for different glass curvatures, leading to increased production costs and potential mismatches in light-guiding effects.
Innovation Solution
A modular design using multiple independent light-guiding blocks that can be adjusted to match different glass curvatures, combined to form a universal light-guiding structure, with LED particles positioned to ensure uniform light transmission across various glass types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a curved light-guiding strip is used to match the glass curvature, then the light-guiding effect is improved, but the manufacturing cost increases and the device is not universally applicable
Solution Approach 1:
The curved light-guiding strip is divided into multiple straight light-guiding blocks that can be independently adjusted. Each block can be positioned and angled separately to collectively form the required curved light-guiding path, eliminating the need for custom curved strips for each glass type while maintaining accurate light guidance.
2Reliability
If a custom curved light-guiding strip is developed for each glass type, then the light-guiding effect is optimized, but the product development cost increases
Solution Approach 1:
The straight light-guiding blocks are designed as universal components that can be used across different glass types by adjusting their positions and angles. A single set of block designs serves multiple applications, eliminating the need to develop custom curved strips for each glass curvature and reducing overall product development complexity.
3Ease of manufacture
If a curved light-guiding strip is used, then the light transmission is improved, but the manufacturing precision requirement increases
Solution Approach 1:
By segmenting the curved strip into multiple straight blocks, the manufacturing precision requirement shifts from creating a complex curved shape to assembling simpler straight components. The precision is distributed across multiple adjustable joints rather than requiring high precision in a single molded curve, making the manufacturing process easier while maintaining overall light-guiding accuracy.

AI summary
The present disclosure relates to a light source module for an atmosphere light and an ambient glass. The light source module is disposed at an edge of a light-guiding glass. The light source module includes multiple light-guiding blocks and light-emitting diode (LED) particles. The multiple light-guiding blocks are arranged along a side edge of the light-guiding glass to constitute a curved light-guiding structure, and the curved light-guiding structure has a radian matching the side edge of the light-guiding glass. The LED particles are disposed at at least one end of the curved light-guiding structure, and lights emitted by the LED particles are uniformly dispersed by the light-guiding structure to be incident into the light-guiding glass. The multiple independent light-guiding blocks are combined to constitute the curved light-guiding structure, so a position and an angle of each independent light-guiding block can be adjusted according to curvatures of different light-guiding glasses to adjust the radian of the curved light-guiding structure to match different glasses, such that the multiple light-guiding blocks are universal and different light-guiding strips need not to be developed for different types of atmosphere lights.
