Transparent Flexible Display for Vehicle Glare Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle display devices are fixed and occupy space even when not in use, failing to adapt to varying light conditions and occupant needs, which can lead to reduced readability due to sunlight glare.
Innovation Solution
A vehicle display device featuring a transparent flexible display that can be rolled around a shaft and adjusted in length using a drive unit, controlled by a processor to optimize light blocking and image display based on sun position and occupant gaze, ensuring unobstructed vision and safe driving assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed display device is installed in the vehicle, then the display can show predetermined content, but it occupies space even when not in use and reduces readability due to sunlight glare
Solution Approach 1:
The display device transitions from a fixed state to a movable state, allowing it to be repositioned or folded away when not in use. The display unit can be moved to different positions on the sun visor or folded into a compact form, dynamically adapting to the user's needs and reducing sunlight glare interference.
Solution Approach 2:
The display device is divided into separable components that can be independently positioned or folded. The display unit can be detached or folded away from the main sun visor structure, allowing the blocking area to be separated from the viewing area when the display is not in use.
2Adaptability or versatility
If a fixed display device is installed in the vehicle, then the display can show predetermined content, but it occupies space even when not in use
Solution Approach 1:
The display device incorporates movable and foldable mechanisms that allow it to transition between deployed and retracted states. When not in use, the display unit can be folded into a compact form or moved to a storage position, significantly reducing the space it occupies while maintaining full functionality when needed.
Solution Approach 2:
The display unit is designed to nest within or attach to the sun visor structure when not in use. The display can be folded into the sun visor housing or positioned in a compact configuration that minimizes the volume it occupies, similar to a nested doll structure.
3Illumination intensity
If a transparent flexible display is used, then the vision of the occupant is not blocked, but the display needs to be adjustable in length to adapt to different conditions
Solution Approach 1:
The transparent flexible display is integrated with a drive unit that enables dynamic adjustment of the display's length and position. The display can be extended or retracted based on lighting conditions, sun position, and occupant needs, allowing the system to adapt without requiring complex manual adjustment mechanisms.
Solution Approach 2:
The drive unit automatically adjusts the display length based on sensor input regarding light conditions and sun position, eliminating the need for complex manual adjustment mechanisms. The system self-regulates the display configuration to optimize visibility while maintaining simplicity.
