Road Marking Projection System for Accurate Line Painting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for drawing road markings require manual labor to create auxiliary lines, which reduces work efficiency and necessitates skilled artisans for accurate line drawing.
Innovation Solution
A projection system that includes a user interface for setting an output image containing a line drawing as a reference for road markings, which is projected onto the road surface to guide the painting process, allowing for efficient and accurate line drawing even by beginners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual work is used to draw auxiliary lines for road markings, then the lines can be drawn with sufficient accuracy, but work efficiency is reduced and skilled artisans are required
Solution Approach 1:
The patent uses projection to create a visual copy of the road marking and auxiliary lines on the road surface. The projection device displays the planned road marking and guide lines directly onto the road, allowing workers to follow the projected image instead of manually drawing lines, thereby eliminating the need for skilled artisans while maintaining accuracy
Solution Approach 2:
The patent replaces the mechanical manual drawing process with an optical projection system. Instead of using physical tools to draw lines on the road surface, the system uses projected light to display guide lines and road marking patterns, substituting mechanical labor with optical information display to improve efficiency and reduce skill requirements
2Manufacturing precision
If manual drawing of auxiliary lines is performed, then line accuracy can be maintained, but the time required for preparation increases
Solution Approach 1:
The patent performs preliminary action by pre-calculating and pre-displaying the road marking patterns and auxiliary lines through projection before the actual painting work begins. The projection system shows the complete guide lines and marking patterns in advance, allowing workers to immediately start painting without time-consuming manual measurement and drawing processes
Solution Approach 2:
The projection system creates a visual copy of the precise road marking design directly on the road surface. This copied image includes all necessary guide lines and patterns that would otherwise require manual drawing, providing workers with accurate reference lines instantly without the time investment needed for manual preparation
