Vertical Rubber Strips for No Entry Sign Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road markings for no right of way indications can be obscured by parked vehicles, vegetation, or advertisements, leading to missed signals and potential traffic conflicts, as they may be damaged, hidden, or not easily visible.
Innovation Solution
Rubber partition strips of alternating white and red colors, which can be fixed on the road surface, providing an additional visual warning by running alongside pavements or barriers, complementing existing traffic signs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional traffic signs and road markings are used to indicate no right of way, then the indication can be placed on the road, but the marking can be obscured by parked vehicles, vegetation, or advertisements, leading to missed signals
Solution Approach 1:
The patent transitions from two-dimensional road surface markings to three-dimensional vertical strips that extend above the road surface. These vertical elements protrude into the driver's field of view, making them visible above parked vehicles and other obstructions that block traditional flat markings on the road surface.
Solution Approach 2:
The patent employs alternating red and white vertical stripes on the vertical strips, creating high-contrast visual patterns that are more noticeable and easier to distinguish from the surrounding environment. This color alternation enhances visibility and draws driver attention more effectively than traditional single-color markings.
2Loss of information
If traffic signs are placed on the road, then they can provide no right of way indication, but drivers may simply miss the traffic sign
Solution Approach 1:
By extending the indication vertically above the road surface, the patent creates a three-dimensional visual element that occupies the driver's peripheral vision and field of view. This vertical projection makes the indication impossible to miss, as it appears in the driver's visual path rather than being flat on the road surface where it can be overlooked.
Solution Approach 2:
The alternating red and white vertical stripes create a high-contrast, visually striking pattern that naturally attracts driver attention. The contrasting colors and vertical orientation make the indication stand out from the typical road environment, ensuring drivers notice and process the no right of way message.
3Reliability
If existing road markings are used, then they can indicate no right of way, but they may be damaged, hidden, or not easily visible
Solution Approach 1:
The vertical strips extend above the road surface into the air space, positioning the indication above the level where typical damage from vehicles or environmental factors occurs. This elevation protects the marking from being covered by parked vehicles, obscured by vegetation, or damaged by road-related activities.
Solution Approach 2:
The patent appears to use composite construction for the vertical strips, combining materials that provide both structural durability and visual visibility. The strips are designed to withstand environmental conditions while maintaining their high-visibility appearance, potentially using weather-resistant materials with integrated reflective or high-contrast coloring.

AI summary
Alternating white and red strips, 2m long and 30cm wide, fluorescent or not, which are placed in such a way that they meet a vertical red strip, long as much as the width of the road and 30cm wide, located at the point of the existing signs.
