Vehicle Badge Illumination with Segmented Light Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle lighting systems lack the ability to independently and efficiently illuminate specific features and areas around a vehicle using multiple light sources, limiting their aesthetic and functional capabilities.
Innovation Solution
A badge system with multiple light sources, including a viewable portion, feature portion, and peripheral light sources, is designed to be independently controlled by a controller, allowing for customizable illumination of various features and areas around the vehicle, such as door handles and ground areas, using LEDs and optical components to direct light effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single light source is used in the badge, then the device complexity is reduced, but the ability to independently illuminate specific features and areas is limited
Solution Approach 1:
The badge lighting system is segmented into multiple independent light sources (first light source for viewable portion, second light source for feature portion, third light source for periphery) that can be controlled separately. This segmentation enables independent illumination of different features while maintaining manageable system complexity through modular design
2Illumination intensity
If multiple light sources are used to illuminate different areas, then the illumination precision and visual appeal are improved, but the energy consumption increases
Solution Approach 1:
The controller enables selective and periodic activation of different light sources based on operational requirements. Instead of all light sources operating continuously, the system activates specific light sources (first, second, or third) periodically or selectively based on the desired illumination effect, reducing overall energy consumption while maintaining high illumination precision when needed
3Ease of operation
If light sources illuminate all areas simultaneously, then the overall visibility is improved, but the ability to highlight specific features is reduced
Solution Approach 1:
The lighting system segments illumination into distinct zones controlled by separate light sources: the first light source provides general viewable portion illumination, the second light source specifically illuminates the feature portion, and the third light source lights the periphery. This segmentation allows the controller to activate only the necessary light sources for each situation, ensuring both overall visibility and precise feature highlighting
Solution Approach 2:
Different light sources provide different illumination qualities to different areas: the first light source provides general illumination for overall visibility, while the second light source provides focused, intense illumination specifically on the feature portion to highlight it. This local quality differentiation enables simultaneous achievement of overall visibility and feature emphasis
Applied Scientific Principles
