Tilt Analysis System for Columnar Objects Using Optical Surveying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring the verticality of column members in construction sites require multiple people and pre-input design values, making them labor-intensive and inefficient, especially in situations where on-site adjustments are necessary.
Innovation Solution
A tilt analysis system that includes a surveying device, a survey target device with a reflector and magnetic attachment, and a portable terminal device, allowing for single-person operation by irradiating the survey target device with surveying light to acquire reference and column top values, generating tilt information, and outputting it to a portable terminal for adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a typical transit is used to measure the verticality of each column, then measurement accuracy is maintained, but multiple operators are required making the process labor-intensive
Solution Approach 1:
The patent replaces the traditional mechanical transit measurement system with an optical surveying device system. The surveying device irradiates surveying light that reflects off the survey target device, eliminating the need for manual transit operation while maintaining measurement accuracy. This substitution allows single-person operation while preserving the core measurement function.
Solution Approach 2:
The survey target device acts as an intermediary between the surveying device and the columnar object. It receives surveying light and reflects it back, enabling automatic position detection without requiring manual intervention. This intermediary component bridges the gap between automated surveying and traditional manual measurement methods.
2Measurement precision
If pre-input design values are required for tilt calculation, then accurate tilt analysis is achieved, but additional preparation time and complexity are introduced
Solution Approach 1:
The system performs self-service by automatically acquiring reference values directly from the construction site using the surveying device. Instead of requiring external input of design values, the system surveys the actual bottom position of the columnar object and uses this as the reference, eliminating the need for pre-work data preparation while maintaining measurement accuracy.
Solution Approach 2:
The system performs preliminary surveying of the bottom position of the columnar object to establish the reference value before conducting the main tilt measurement. This preliminary action captures the actual as-built position, which then serves as the baseline for accurate tilt calculation without requiring separate design value input.
3Adaptability or versatility
If design values are re-input after on-site adjustment, then updated tilt analysis is possible, but additional time and labor are required
Solution Approach 1:
The system implements feedback by continuously surveying the position of the survey target device on the columnar object and automatically recalculating tilt values. When on-site adjustments are made, the operator simply re-surveys the position, and the system immediately provides updated tilt information, eliminating the need for manual re-input of design values and enabling rapid adaptation to changes.
