Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle cabin lighting systems lack flexibility and aesthetic appeal in providing light to desired locations, often being too intense or inefficiently designed.
Innovation Solution
A laminated glazing with integrated lighting systems featuring light guides and extraction zones that allow for customizable light distribution and intensity, including multiple light sources and extraction means to provide ambient lighting throughout the vehicle cabin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional centrally located cabin lights are used, then the lighting system is simple to implement, but the light intensity is too intense for some passengers and lacks flexibility in providing light to different locations
Solution Approach 1:
The lighting system is segmented into multiple independent light sources (first light source, second light source) with separate light guides (first light guide, second light guide) that can be independently controlled. This allows different zones of the cabin to receive light of different intensities, providing flexibility and adaptability while resolving the contradiction between versatility and complexity.
Solution Approach 2:
Different regions of the cabin are provided with different lighting characteristics through separate light guides and extraction zones. The first light guide provides light to one area while the second light guide provides light to another area, allowing local adjustment of light intensity and distribution to meet different passenger needs.
2Shape
If light guides are integrated within the laminated structure, then aesthetic appearance and space efficiency are improved, but the device complexity increases
Solution Approach 1:
The lighting system components (light sources, light guides, extraction zones) are merged into the laminated glazing structure itself. The light guides are positioned between the glass sheets and interlayer, combining the structural and lighting functions into a single integrated assembly, which improves aesthetics and space efficiency while the modular design manages the complexity.
Solution Approach 2:
The laminated glazing structure serves multiple functions: it provides structural integrity as a windshield or window, while simultaneously housing the lighting system components. The light guides and extraction zones are integrated into the same structure that provides mechanical support, making the system multi-functional and reducing the need for separate mounting structures.

Function Achieved in This Case
The solution provides flexible, aesthetically pleasing, and intensity-adjustable lighting to vehicle interiors, enhancing user comfort and design.
Implementation Method 1
a first light guide with a first end and a second end, the first end surrounding the first light source, the second end providing an opening to a second light guide
Implementation Method 2
The second light guide may include a second extraction zone, including a second light extraction means wherein light in the second light guide is extracted by the second light extraction means at the second light extraction zone
