Vehicle Navigation Projection System Reducing Driver Distraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers are distracted by navigation systems while driving, as they need to frequently check the screen for driving information, leading to potential traffic accidents.
Innovation Solution
A method and apparatus for projecting driving information, such as route directions and distance, in front of the vehicle using a driving information projecting apparatus equipped with a display unit and a lighting unit, which obtains information from navigation systems or GPS, allowing safe and convenient access to travel guidance without screen distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If driving information is displayed on a screen (liquid crystal display), then navigation functionality is provided, but driver attention is distracted and safe driving is hindered
Solution Approach 1:
The patent transitions the display dimension from a vertical screen (requiring head movement and eye focus away from the road) to a horizontal projection on the windshield or dashboard surface (maintaining forward gaze). This dimensional change allows drivers to access navigation information without breaking their visual contact with the road, thus maintaining safety while providing information access.
2Loss of information
If a separate navigation display unit is provided, then driving information is available, but the device complexity increases
Solution Approach 1:
The patent merges the navigation display function with the existing vehicle windshield or dashboard surface. Instead of adding a separate screen that requires additional mounting space, power connections, and control interfaces, the navigation information is projected onto the existing surface, integrating the navigation function into the vehicle's existing structure and reducing overall system complexity.
Solution Approach 2:
The windshield or dashboard surface serves multiple functions: it acts as both the structural component of the vehicle interior and the display surface for navigation information. This multi-functionality eliminates the need for dedicated display hardware, reducing device complexity while maintaining information availability.
