Road Surface Marking Projection Layout Without Satellite Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road surface marking techniques require skilled operators, on-site surveys, and large-scale apparatuses that are difficult to use under limited conditions, imposing burdens on constructors and operators.
Innovation Solution
A projection system comprising a projector, a base, and a moving mechanism that allows for the instantaneous projection of road surface markings onto a road surface, reducing the need for on-site surveys and enabling easy, quick, and accurate marking without the need for satellite connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If satellite communication systems are used for road surface marking, then positioning accuracy is improved, but device complexity and portability deteriorate
Solution Approach 1:
The patent uses a projector to create a visual copy of the road surface marking layout directly on the road surface, eliminating the need for complex satellite communication systems. The projector displays the marking pattern as an optical copy that operators can follow, replacing sophisticated positioning technology with simple visual guidance.
Solution Approach 2:
The patent replaces the mechanical and electronic complexity of satellite communication systems with a simpler optical projection system. Instead of using GPS satellites and complex signal processing, the invention uses a projector to display marking guidelines directly on the road surface, substituting a complex electromechanical system with a straightforward optical device.
2Manufacturing precision
If on-site survey and drafting is performed manually, then marking accuracy is improved, but labor burden and time consumption increase
Solution Approach 1:
The projector creates a visual copy of the desired road surface marking layout directly on the actual road surface. This allows operators to see the exact marking pattern, position, and dimensions before painting, maintaining accuracy while eliminating manual surveying and drafting work. The optical copy replaces the need for skilled operators to manually measure and mark guidelines.
Solution Approach 2:
The system performs preliminary action by projecting the complete marking layout onto the road surface before the actual painting begins. This allows all planning, measurement, and design decisions to be made in advance and displayed visually, so that during the painting phase, operators simply need to follow the projected guidelines without performing any surveying or calculation tasks.
3Reliability
If traffic restriction is imposed for road surface marking work, then marking safety is improved, but social impact and operational flexibility worsen
Solution Approach 1:
The patent applies partial action by using only the portion of the road surface needed for projection display rather than closing the entire road. The projector displays marking guidelines on a limited area, allowing traffic to continue flowing while workers perform marking tasks. This partial use of road space maintains safety for the specific work zone while preserving overall road accessibility and operational flexibility.

AI summary
A projection system is configured to project an image used to paint a road surface marking on a road surface onto the road surface, and includes a projector configured to project the image toward the road surface; a first installer at which the projector is installed; a base at which the first installer is provided; and a moving mechanism configured to move the base.
