Front Windshield Recessed Perception Mark for Lateral Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing front windshields do not effectively facilitate spacing between vehicles in the right-left direction and can confuse perception marks with dust or other objects, affecting driving accuracy and safety.
Innovation Solution
A front windshield design featuring a frame portion along the circumferential edge with recesses and perception marks positioned inside these recesses, allowing drivers to perceive vehicle position and orientation without obstructing their view, and preventing confusion with dust or objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the perception mark is provided away from the frame portion of the front windshield, then the driver can perceive the vehicle position, but the perception mark may be mistaken as dust or other objects attached to the front windshield
Solution Approach 1:
The perception mark is merged with the frame portion by placing it inside a recess of the frame. This integration ensures the mark is perceived as part of the vehicle structure rather than external contamination, resolving the confusion with dust or objects while maintaining its positional guidance function
2Loss of information
If the perception mark is provided in a position shifted upward from the frame portion, then the driver can perceive the vehicle position, but the technique does not facilitate spacing between vehicles in the right-left direction
Solution Approach 1:
The recess is positioned at the lower edge portion of the frame where it most effectively aids lateral spacing perception. This localized placement optimizes the mark's utility for judging horizontal distance between vehicles while maintaining clear visibility for position perception

AI summary
A front windshield includes a frame portion extending along the circumferential edge, the frame portion includes a lower edge portion extending along the lower edge of the front windshield, and a recess depressed downward from the inner edge of the lower edge portion, and at least a part of a perception mark, which allows the driver of the vehicle to perceive a position based on the vehicle, is provided inside the recess.
