Flip-Dot Vehicle Display With Adaptive Lighting for Night Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles need to effectively communicate their driving state and surrounding situation to pedestrians and oncoming vehicles, both day and night, while existing display technologies lack sufficient visibility and efficiency in conveying this information.
Innovation Solution
A vehicle information display apparatus featuring a flip-dot display and an illumination device, which uses a control unit to output recognition, warning, and cancellation information through pixel-based symbols, icons, and characters, along with sound outputs, and adjusts illumination based on ambient brightness and detected distances, utilizing electromagnets to rotate flip disks with different reflection characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a flip-dot display is used to convey vehicle information, then information transfer efficiency is improved, but visibility in nighttime conditions deteriorates
Solution Approach 1:
The patent combines a flip-dot display with an illumination device into an integrated system. The illumination device includes light sources positioned around the flip-dot display to provide backlighting, ensuring that the displayed information remains visible in nighttime conditions while maintaining the high information transfer efficiency of the flip-dot technology.
Solution Approach 2:
The display system serves multiple functions: it displays vehicle information during daytime using the flip-dot mechanism, and automatically activates the illumination device during nighttime to maintain visibility. This multi-functional approach allows the same system to effectively operate under different lighting conditions without requiring separate display systems.
2Illumination intensity
If traditional display technologies are used, then visibility is maintained, but information transfer efficiency deteriorates
Solution Approach 1:
The display system segments information into different types (recognition information, warning information, cancellation information) and uses the flip-dot display's mechanical flipping capability to convey these segments clearly. The illumination device segments its lighting function to enhance specific areas of the display as needed, maintaining high visibility while supporting efficient information transfer through structured presentation.
3Illumination intensity
If illumination is added to improve nighttime visibility, then visibility is improved, but device complexity increases
Solution Approach 1:
The illumination device is merged with the flip-dot display assembly, sharing common structural elements, mounting mechanisms, and control systems. This integration reduces the overall system complexity compared to adding a separate illumination system, as the lighting components are incorporated into the existing display framework rather than requiring independent installation and control.
