Vehicle Illumination Assembly with Dynamic Image Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicular lighting systems lack the ability to dynamically adjust illumination patterns and generate images to assist drivers in navigating around objects, especially in low-light conditions, which can hinder parking and maneuvering tasks.
Innovation Solution
The proposed solution involves an illumination assembly with a first light source generating an illumination pattern and a second light source configured to create an image within the pattern, optically coupled with a lens and controlled by a controller. This assembly includes luminescent structures that convert excitation light into visible light, allowing for adaptive lighting and image generation to guide drivers during parking and maneuvering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a traditional single light source illumination system is used, then the device complexity is low, but the illumination intensity and adaptability are insufficient for dynamic lighting needs
Solution Approach 1:
The patent combines multiple light sources (first light source for illumination pattern, second light source for image generation) into a single illumination assembly, merging their functions to achieve both high illumination intensity and dynamic adaptability while managing device complexity through integrated design
Solution Approach 2:
The illumination assembly is designed with multi-functionality, where the first light source provides general illumination and the second light source generates directional images, allowing the system to perform multiple lighting functions simultaneously and adapt to different driving conditions
2Adaptability or versatility
If standard lighting systems are used, then the manufacturing cost is low, but the adaptability for dynamic lighting conditions is poor
Solution Approach 1:
The patent implements dynamic adaptability by enabling the illumination assembly to adjust its lighting patterns and image generation based on detected driving conditions, allowing the system to adapt to varying environmental requirements while maintaining manufacturing feasibility through controlled complexity
Solution Approach 2:
The system incorporates sensors that detect driving conditions and provide feedback to the controller, which then adjusts the activation states of the light sources accordingly, enabling real-time adaptability to changing lighting and environmental conditions
3Adaptability or versatility
If multiple light sources are used for dynamic illumination and image generation, then the adaptability and driver assistance capability are improved, but the energy consumption increases
Solution Approach 1:
The controller manages energy consumption by periodically activating the second light source only when image generation is required for specific driving conditions, rather than operating continuously, thus reducing overall energy consumption while maintaining adaptability when needed
Solution Approach 2:
The system applies local quality by using the second light source to generate images only in specific directional regions where additional guidance is needed, rather than illuminating the entire area uniformly, thereby reducing energy consumption while maintaining adaptability in critical zones
