Illuminated Assembly Light-Diffusing Element Color Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for vehicular lighting solutions that can be implemented at low costs with minimal packaging constraints and provide unique aesthetic options beyond conventional lighting sources, while also being able to notify occupants and external observers of vehicle status through varying light wavelengths.
Innovation Solution
An illuminated assembly is designed with a light-diffusing element between outer and inner panels, where a light source directs light into the diffusing element to provide notifications outwardly, utilizing luminescent structures that convert excitation light into different wavelengths for various lighting effects, including color changes to indicate wait times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional lighting sources are used, then the lighting solution is simple and cost-effective, but unique lighting aesthetics and multiple wavelength notifications cannot be achieved
Solution Approach 1:
The patent applies color changes by incorporating a light-diffusing element containing wavelength-selective materials (such as phosphors or colored gels) that convert a single wavelength light source into multiple wavelengths. This allows the system to display different colors for various notifications (e.g., blue for ready, red for occupied) without requiring multiple light sources, thus achieving versatility while maintaining simplicity
Solution Approach 2:
The light-diffusing element acts as an intermediary between the light source and the external environment. It receives light from a simple light source and transforms it into multiple wavelengths through phosphorescent conversion or selective absorption/re-emission, enabling complex lighting aesthetics and notification capabilities without directly complicating the light source itself
2Loss of information
If multiple light sources are used to provide various wavelengths, then notification capability is improved, but manufacturing cost and packaging constraints increase
Solution Approach 1:
The light-diffusing element serves multiple functions simultaneously: it diffuses light for aesthetic purposes, converts wavelengths for notification purposes, and can be integrated into existing window or panel structures. This multi-functionality eliminates the need for separate notification systems, reducing manufacturing complexity and packaging requirements while maintaining comprehensive status communication capability
Solution Approach 2:
The patent merges the lighting aesthetic function and the notification function into a single integrated light-diffusing element. By combining these functions, the system avoids the need for separate light sources and control systems for each function, thereby reducing manufacturing costs and simplifying packaging while achieving both aesthetic appeal and effective vehicle status communication
