Solution Overview
Problem
Existing road surface marking techniques require skilled operators, on-site surveys, and large-scale satellite-dependent equipment, leading to burdensome and time-consuming processes that disrupt traffic and limit user accessibility.
Innovation Solution
A projection system comprising a projector, installer, and moving mechanism that allows for the direct projection and drafting of road surface markings onto a road surface, enabling easy and quick marking without the need for skilled operators or 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 scale increase
Solution Approach 1:
The patent uses a camera to capture images of the road surface and creates a two-dimensional map that copies the road layout. This eliminates the need for satellite communication systems while achieving accurate positioning for road surface marking. The camera-based imaging system replaces complex satellite-dependent equipment with a simple optical copying mechanism.
2Manufacturing precision
If on-site survey and auxiliary line drafting are performed, then marking accuracy is improved, but time consumption and traffic disruption increase
Solution Approach 1:
The patent performs preliminary actions by capturing road surface images and generating two-dimensional maps before the actual marking process. This pre-positioning and pre-planning allows the marking to be executed quickly and accurately without time-consuming on-site survey and auxiliary line drafting, thereby reducing traffic disruption.
Solution Approach 2:
The patent replaces manual mechanical drafting of auxiliary lines with an automated image processing system. The camera captures the road surface, and software automatically generates a two-dimensional map with precise positioning information, eliminating the need for operators to manually draft lines and significantly reducing work time.
3Manufacturing precision
If skilled operators perform road surface marking, then marking quality is improved, but operational difficulty and training requirements increase
Solution Approach 1:
The patent implements self-service by enabling the system to automatically capture road images, generate two-dimensional maps, calculate positioning information, and guide the marking process without requiring skilled operators. The system serves itself by autonomously performing tasks that previously required human expertise, thereby improving ease of operation while maintaining marking quality.
