Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road surface marking systems require skilled operators for on-site surveys and preliminary sketching, imposing burdens and restricting traffic, and satellite-dependent systems are cumbersome and limited in usability.
Innovation Solution
A projection system that projects images onto a road surface using a projector with S-polarized red, green, and blue light, featuring a base with movement mechanisms and installation sections to facilitate easy and accurate marking without the need for skilled operators or satellite connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If satellite communication systems are used for road surface marking painting, then painting accuracy is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent replaces satellite communication systems with a projector-based visual guidance system. The projector displays marking patterns directly on the road surface, allowing operators to follow visual guidelines without needing complex satellite communication equipment. This substitution maintains painting accuracy while significantly reducing device complexity and improving ease of operation.
2Manufacturing precision
If on-site survey and preliminary sketching are performed by skilled operators, then marking accuracy is improved, but loss of time and productivity deteriorate
Solution Approach 1:
The projector system performs the preliminary sketching function automatically by projecting the marking pattern directly onto the road surface. This eliminates the need for manual surveying and sketching by skilled operators, allowing less skilled workers to follow the projected guidelines. The system serves itself by providing visual guidance without requiring extensive human expertise, thereby improving productivity while maintaining marking accuracy.
3Manufacturing precision
If traffic restriction is imposed for drafting work, then marking quality is improved, but loss of time and social harm worsen
Solution Approach 1:
The projector displays the complete marking pattern in advance on the road surface, allowing operators to prepare and execute the painting work efficiently in a single pass. This preliminary visualization of the entire marking pattern enables workers to complete the task quickly without prolonged traffic restrictions, thereby maintaining marking quality while reducing the harmful effect of traffic disruption.
