Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for making informational markings on surfaces, such as the ground, are labor-intensive and time-consuming, requiring manual application of paint and temporary string lines for location markings before construction processes.
Innovation Solution
A vehicle-mounted ground marking system equipped with a position signal receiver, a paint supply, actuators, and a processor that uses predetermined positional data to automatically adjust the paint supply's position for accurate marking, eliminating the need for pre-installation of string lines and enabling quick and efficient application of markings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual paint application and string line installation are used, then marking accuracy can be achieved, but labor intensity and time consumption increase significantly
Solution Approach 1:
The patent replaces manual mechanical operations with an automated vehicle-mounted system that uses GPS positioning and computer-controlled paint application. The system automatically navigates to marked locations and applies paint without manual string line installation, substituting mechanical labor with automated electronic control systems.
Solution Approach 2:
The system enables self-service marking by using pre-stored coordinate data to automatically determine marking locations and guide the vehicle. The GPS receiver and controller work together to autonomously position the vehicle and trigger paint application without requiring manual measurement or string line reference.
2Productivity
If automated vehicle-mounted marking system is used, then productivity increases, but device complexity increases
Solution Approach 1:
The vehicle-mounted system integrates multiple functions into a single platform: GPS positioning, navigation to marked coordinates, automated paint application control, and data storage. This multi-functional integration achieves high productivity while managing complexity by combining rather than separating functions.
Solution Approach 2:
The controller acts as an intermediary between the GPS receiver and the paint application mechanism. It processes coordinate data from memory, compares it with real-time GPS position data, and automatically controls paint discharge timing, simplifying the overall control architecture through centralized intermediate processing.
3Manufacturing precision
If manual marking methods are used, then equipment requirements are simple, but marking precision and alignment with construction plans may vary
Solution Approach 1:
The system continuously receives real-time position feedback from the GPS receiver and compares it with the stored coordinate data. The controller uses this feedback to determine when the vehicle has reached the precise marking location and automatically triggers paint application, ensuring accurate alignment with construction plans through continuous position verification.
Solution Approach 2:
The construction plan coordinates are pre-stored in the system's memory device before field operations. This preliminary data preparation eliminates the need for manual measurement and string line installation during marking, as the system already contains the precise location information needed for accurate marking alignment.

AI summary
A ground marking system includes a position signal receiver configured to receive a position signal and generate current position information based on the position signal. A paint supply is configured to discharge paint onto ground beneath the paint supply. A first actuator is operatively connected to the paint supply for linearly moving the paint supply in both a first direction and a second direction opposite the first direction. A second actuator is operatively connected to the paint supply for controlling the discharge of paint from the paint supply. A memory device stores predetermined positional data. A processor is in communication with the position signal receiver and the memory device, and is configured to control linear movements of the first actuator based on the current position information received from the position signal receiver and the predetermined positional data stored in the memory device, and adjust a position of the paint supply.
