Windshield Projection Display for Vehicle Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driving information display devices obstruct the driver's vision and require them to divert attention from the road, increasing the risk of accidents, especially at high speeds, due to their placement on dashboards or helmets, which can cause distraction and are difficult to operate safely.
Innovation Solution
A portable driving information display device with a projection mechanism that projects vital information, such as speed and GPS data, onto a screen within the driver's field of vision, using a signal unit and fastening arrangement to secure it to the vehicle, allowing for customizable and toggleable display without obstructing the view, and featuring an activation switch for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If driving information is displayed on dashboard instruments, then the user can access driving information, but the user must divert their vision from the road to view the instruments
Solution Approach 1:
The display is moved from the traditional horizontal dashboard plane to a vertical windshield surface, allowing information to be presented in the driver's forward field of vision without requiring head movement or gaze diversion from the road
2Loss of information
If the display device is mounted on the user's helmet, then the information is within the user's field of vision, but the device obscures the user's vision and creates confusion with real world objects
Solution Approach 1:
The display is positioned on the windshield in the distance rather than on the helmet close to the eye, utilizing the spatial dimension to eliminate vision obstruction while maintaining information accessibility in the driver's field of view
Solution Approach 2:
The windshield acts as an intermediary surface between the driver and the road, projecting information onto it without blocking the view of real-world objects, thus mediating between information display and visual clarity
3Loss of information
If the display device is always activated, then the information is continuously available, but the user cannot turn it off safely without taking hands off the steering mechanism
Solution Approach 1:
The display automatically activates and deactivates based on vehicle operation state (ignition on/off), eliminating the need for manual control while maintaining continuous information availability when the vehicle is running
Solution Approach 2:
The display status is linked to vehicle ignition status, providing automatic feedback-based control where the system activates or deactivates based on the vehicle's operational state without requiring manual intervention
Data Source
AI summary
A driving information display device includes a data generator for generating driving information of a vehicle and a display unit linked to the data generator for being supported at a desired location of the vehicle. The display unit provides visualizations regarding driving information to a driver during driving. These visualizations relates to driving data if the user is operating a motorized vehicle, GPS navigational information, etc. These visualizations are then provided at the driver's field of vision, which allows the driver to keep the eyes on the road while still being able to analyze the information. This allows the driver to operate the vehicle safely and in turn enjoy more fulfilled and enjoyable driving experience.
