Solution Overview
Problem
Current plumbing methods for constructing structures, such as using plumb bobs, transits, and laser plummet instruments, are inefficient and dependent on worker experience, requiring multiple processes and time to ensure verticality of column members, leading to instability in plumbing accuracy.
Innovation Solution
An analysis system utilizing a laser scanner to generate three-dimensional point cloud data, a server to analyze the data, and an information terminal to display results, which collectively detects and calculates the inclination of column members, allowing for stable and efficient plumbing by reducing the need for manual adjustment of each column individually.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional plumbing methods (plumb bob, transit, laser plummet instrument) are used, then verticality of column members can be measured, but the process requires many work steps and time, reducing productivity
Solution Approach 1:
The patent combines multiple measurement functions into a single 3D laser scanner that captures point cloud data of multiple column members simultaneously. Instead of using separate instruments (plumb bob, transit, or laser plummet) for each column, the system merges all measurement capabilities into one device that processes multiple targets at once, dramatically improving productivity while maintaining accuracy through comprehensive data capture
Solution Approach 2:
The patent replaces traditional mechanical measurement systems (plumb bob swinging mechanism, transit optical system, laser plummet alignment system) with a 3D laser scanning system that uses light time-of-flight or phase measurement to determine positions. This substitution eliminates the need for manual setup and adjustment of each instrument while providing automated data collection and processing, resolving the contradiction between measurement precision and productivity
2Measurement precision
If manual measurement and adjustment of each column member is performed, then inclination can be checked, but it requires many workers and experiences, leading to instability in plumbing accuracy
Solution Approach 1:
The system enables self-service measurement where the 3D laser scanner automatically captures point cloud data, the server automatically processes the data to calculate inclinations, and the information terminal automatically displays results. This eliminates dependency on workers' manual measurement skills and experiences, providing consistent and stable plumbing accuracy through automated processing without requiring human intervention or expertise in measurement techniques
Solution Approach 2:
The patent implements a feedback system where the 3D laser scanner continuously monitors column member inclinations, the server processes the data to determine deviations from verticality, and the information terminal provides real-time feedback to workers. This closed-loop feedback mechanism ensures stable plumbing accuracy by continuously verifying measurements and allowing for immediate corrections, removing dependence on individual workers' experience levels
3Measurement precision
If laser plummet instrument is used to detect inclination, then verticality can be determined, but workers need to set-up and remove the instrument and point, increasing time consumption
Solution Approach 1:
The patent applies preliminary action by having the 3D laser scanner positioned in advance to capture point cloud data of all column members in the work area before measurement begins. The server then processes this pre-captured data to calculate inclinations, eliminating the need for time-consuming setup and removal of instruments at each measurement location. The preliminary data capture enables rapid analysis without repeated instrument positioning
Solution Approach 2:
The 3D laser scanner serves as a universal measurement device that can measure multiple column members simultaneously from various positions and angles, replacing the specialized laser plummet instrument that requires separate setup for each target. This multi-functional capability allows the single scanner to perform all verticality measurements without requiring location-specific instrument setup, significantly reducing time loss
