Solution Overview
Problem
Current technologies lack an efficient method to automatically transfer two-dimensional construction models or instructions onto surfaces like floors with high accuracy and precision, especially in aligning and marking specific coordinates on the floor according to digital designs.
Innovation Solution
A device comprising a chassis that translates along a floor, equipped with an optical prism for signal reflection, a marking assembly, and a controller that receives construction instructions defined by floor coordinates, aligns itself using distance measurement signals, and transfers markings onto the floor by independently adjusting its movement and marking device to match the coordinates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual methods are used to transfer construction models onto floors, then flexibility and adaptability are maintained, but accuracy and precision are insufficient
Solution Approach 1:
The patent replaces manual mechanical methods with an automated system that uses optical signals (laser) for measurement and a motorized carriage for physical marking. The base station emits laser signals that are reflected by a prism on the carriage to automatically determine position and transfer markings, eliminating manual measurement and marking operations while achieving high precision.
Solution Approach 2:
The system enables the marking device to automatically determine its own position through laser signal reflection and automatically adjust its location to match the digital model coordinates. The carriage self-corrects its position based on real-time laser measurement data, reducing the need for external guidance or manual intervention.
2Productivity
If automated marking systems are implemented, then productivity and accuracy are improved, but ease of operation deteriorates due to complex setup and coordination requirements
Solution Approach 1:
The base station serves multiple functions: it emits laser signals for position measurement, receives reflected signals from the prism, and processes data to determine the carriage's location. The single device performs what would otherwise require separate measurement instruments, control systems, and marking devices, simplifying operation while maintaining high productivity.
3Manufacturing precision
If the marking device strictly follows pre-determined paths, then alignment accuracy is improved, but adaptability to actual floor conditions deteriorates
Solution Approach 1:
The system continuously measures the carriage's actual position using laser signals reflected from the prism and compares it with the expected position from the digital model. When deviations are detected, the system provides real-time feedback to adjust the carriage's movement, enabling dynamic correction while maintaining precise alignment with the intended floor markings.
