Inspection Plan Drafting Support System for Structural Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inspection systems for structural objects, such as bridges, inadequately identify inspection locations beyond predicted stress concentration points, leading to insufficient data collection and potential safety concerns.
Innovation Solution
An inspection plan drafting support system that inputs structural and attribute data to determine required inspection locations, prioritizes them based on positional relationships, and creates an efficient inspection plan using stereoscopic structure information and detection results, allowing for precise data acquisition and damage prediction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If inspection focuses only on predicted stress concentration locations, then inspection efficiency is improved, but inspection completeness deteriorates
Solution Approach 1:
The system segments the inspection object into multiple regions with different risk levels. It divides inspection locations into stress concentration locations (high risk) and other locations (lower risk), allowing differentiated inspection strategies for each segment while ensuring comprehensive coverage
Solution Approach 2:
The system changes the parameter of inspection priority by calculating risk levels for different locations based on structural data and inspection results. It dynamically adjusts which locations require inspection and their priority order, moving beyond static focus on only stress concentration points
2Reliability
If comprehensive inspection of all locations is performed, then inspection completeness is improved, but inspection cost and time increase
Solution Approach 1:
The system performs preliminary risk assessment by calculating risk levels for all potential inspection locations before actual inspection. This preliminary action identifies which locations require inspection and their priority order, eliminating the need to inspect all locations equally and reducing overall inspection time
Solution Approach 2:
The system applies partial inspection action by focusing resources on high-risk locations identified through risk calculation, rather than performing excessive full-scale inspection of all areas. It achieves sufficient inspection completeness by targeting the most critical locations

AI summary
A structural object data input unit receives an input of structural data of a target structural object to be inspected, and an attribute information input unit receives an input of attribute information of the target structural object. Next, an inspection location determination unit specifies a location having stress applied thereto in the target structural object, and determines an inspection required location of the target structural object on the basis of a result of the determination. Next, an inspection plan creation unit creates an inspection plan on the basis of the specification result for the inspection required location, and outputs the created inspection plan to a display unit. Thereby, the inspection plan is displayed on the display unit.
