Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle information display systems fail to effectively communicate the driving state and surrounding situation to pedestrians and oncoming vehicles, particularly in varying light conditions, and lack efficient methods to enhance visibility and transfer information accurately.
Innovation Solution
A vehicle information display apparatus incorporating a flip-dot display and an illumination module, controlled by a processor to output recognition, warning, and cancellation information based on detected objects and ambient brightness, utilizing electromagnets to rotate flip disks with different colored surfaces for improved visibility and reduced weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional display system is used to communicate driving state to pedestrians and oncoming vehicles, then the system structure is simple, but the visibility and information transfer accuracy are insufficient especially in varying light conditions
Solution Approach 1:
The patent combines the display unit with an illumination unit into an integrated vehicle information display system. The illumination unit includes a housing and light source that work together with the display unit to provide enhanced visibility of displayed information to pedestrians and oncoming vehicles, particularly in low-light conditions.
Solution Approach 2:
The display unit is designed to display multiple types of information including driving state, surrounding situation, and object information. The illumination unit provides both structural support (housing) and lighting functions, making the system multi-functional and reducing the need for separate components.
2Weight of moving object
If traditional display technologies are used, then the manufacturing process is straightforward, but the weight and manufacturing costs are higher
Solution Approach 1:
The vehicle information display system is divided into distinct functional modules: a display unit and an illumination unit. The illumination unit is further segmented into a housing and a light source. This modular segmentation reduces overall weight while maintaining ease of manufacture through standardized assembly processes.
3Reliability
If the display system does not adapt to ambient light conditions, then the control logic is simple, but the information transfer accuracy to pedestrians and oncoming vehicles deteriorates in nighttime or low-light conditions
Solution Approach 1:
The control unit receives ambient light information and uses this feedback to automatically adjust the illumination of the display. This ensures that the displayed information remains clearly visible to pedestrians and oncoming vehicles regardless of ambient light conditions, improving information transfer reliability.
