Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle lighting systems lack the ability to dynamically display information based on changing driving situations and external conditions, such as speed, road curvature, and external light, which can lead to distractions and reduced safety.
Innovation Solution
A lighting apparatus for vehicles that includes a light output unit, an interface unit, and a processor to generate and control light for displaying visual images corresponding to various information sources, such as travel speed, navigation, and external conditions, using beam pattern units like Digital Micro-mirror Devices (DMD) or Micro Electro Mechanical Systems (MEMS) scanners to adapt the display in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the lighting apparatus displays visual images on the road surface to provide information to the driver, then driver awareness and information delivery are improved, but the risk of driver distraction and safety issues increase
Solution Approach 1:
The lighting apparatus dynamically adjusts the display position, size, and content of visual images based on real-time driving conditions such as vehicle speed, road curvature, and surrounding environment. This dynamic adaptation ensures information is delivered effectively while minimizing distraction risks by adjusting displays to appropriate visibility levels.
Solution Approach 2:
The system changes multiple parameters of the visual display including position, size, brightness, and content based on driving conditions. For example, at higher speeds or on curved roads, the display position and size are adjusted to maintain optimal visibility without causing distraction, directly addressing the contradiction between information delivery and safety.
2Device complexity
If the lighting apparatus provides illumination for the road and displays visual images using the same light source, then device complexity is reduced, but the quality of both illumination and visual display deteriorates
Solution Approach 1:
The lighting apparatus segments the light output into distinct functional zones: one portion provides road illumination while another portion displays visual images. This segmentation allows each function to operate at optimal quality levels while sharing the same overall system structure, resolving the contradiction between simplicity and performance.
Solution Approach 2:
The lighting apparatus is designed as a multi-functional unit that can perform both road illumination and visual image display using the same light source. This universal design reduces device complexity while maintaining adequate quality for both functions through intelligent light distribution and control algorithms.
3Adaptability or versatility
If the lighting apparatus adjusts visual display position and content based on multiple driving conditions, then adaptability and driver awareness are improved, but device complexity and control difficulty increase
Solution Approach 1:
The lighting apparatus incorporates feedback mechanisms that continuously monitor driving conditions such as vehicle speed, road curvature, and environmental factors. This feedback enables automatic adjustment of visual display parameters without requiring complex manual control systems, achieving high adaptability while managing device complexity through intelligent automation.
Solution Approach 2:
The system performs preliminary calculations and preparations for display adjustments based on predicted driving conditions. By anticipating required display changes before they are needed, the control system can be simpler while still achieving high adaptability to varying driving scenarios.
