Vehicle Window Display System for External Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing graphical taillight systems for vehicles are not widely accepted due to increased complexity, cost, and limited size, failing to effectively communicate vehicle operations to pedestrians and other drivers, which can lead to safety issues on highways and roads.
Innovation Solution
A display system integrated into vehicle designs, featuring a display device and a partially reflective window or glass that reflects images visible from outside the vehicle, with adjustable angles and high reflectivity, along with a control unit that automatically adjusts images based on vehicle and environmental parameters, such as tire pressure and weather conditions, to provide real-time communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If graphical taillight systems are implemented to improve communication of vehicle operations, then safety is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines the display device with existing vehicle windows or glass surfaces, merging the communication function into a component that already exists on the vehicle. This eliminates the need for separate graphical taillight assemblies while achieving the same safety communication goal, thereby reducing overall system complexity.
Solution Approach 2:
The window or glass surface serves multiple functions: it maintains its primary function as a vehicle component while simultaneously acting as a reflective surface for displaying graphical information. This multi-functionality reduces the need for additional dedicated components, lowering system complexity and cost.
2Illumination intensity
If display device is positioned to reflect images through window, then visibility from outside vehicle is improved, but manufacturing precision requirements increase
Solution Approach 1:
The system allows for adjustable positioning of the display device relative to the window, enabling dynamic optimization of the reflection angle. This adjustability compensates for variations in window positioning and ensures optimal visibility without requiring extremely tight manufacturing tolerances.
Solution Approach 2:
The patent specifies an optimal angle range (30° to 75°) rather than a single precise angle, allowing manufacturers to achieve acceptable performance within a broader parameter range. This reduces the stringency of manufacturing precision requirements while maintaining effective image visibility.
3Illumination intensity
If window reflectivity is increased to enhance image visibility, then communication effectiveness is improved, but light transmission to drivers may be reduced
Solution Approach 1:
The display device is positioned to illuminate only specific portions of the window at angles that direct reflected light toward external observers. This localized illumination approach ensures high reflectivity where needed for communication while minimizing impact on overall light transmission to drivers through the window.
