Building Soundness Determination via Similar Case Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining the soundness of buildings require extensive expertise and time, often fail to accurately assess damage impact on structural safety, and rely heavily on technician estimation, leading to inefficiencies and inaccuracies in identifying urgent vs. non-urgent repairs.
Innovation Solution
A soundness determination device and method that uses input units for damage and structure information, coupled with a storage unit associating similar damage and structure data from other buildings to rapidly and efficiently determine the soundness of a target building by searching for analogous soundness data, without the need for expert personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If expert technicians perform detailed inspection and analysis of building damage, then determination accuracy is improved, but inspection time and cost increase significantly
Solution Approach 1:
The system performs preliminary actions by pre-storing soundness determination results from multiple expert technicians for various building types and damage patterns in a database. When a new inspection is needed, the system quickly retrieves and compares similar historical cases, providing rapid soundness determination without requiring expert technicians to perform full analysis each time.
Solution Approach 2:
The system creates copies of expert knowledge by storing multiple technicians' determination results and analysis patterns in the database. These stored results serve as reusable templates that can be rapidly applied to similar cases, eliminating the need to recreate expert analysis from scratch for each inspection.
2Measurement precision
If expert technicians conduct comprehensive building inspections, then soundness determination accuracy is improved, but the number of required personnel and costs increase
Solution Approach 1:
The system enables self-service by allowing automated retrieval and comparison of historical soundness determination data without requiring expert technician involvement for each inspection. The database automatically stores and retrieves determination results, enabling rapid assessment while maintaining accuracy through comparison with multiple stored expert opinions.
Solution Approach 2:
Expert knowledge is captured and stored in advance in the database, creating a reusable knowledge base that serves future inspections automatically. This preliminary capture of expert knowledge eliminates the need to engage experts for every inspection while preserving their determination accuracy.
3Productivity
If damage assessment considers only local damage area, then inspection scope is reduced, but structural safety assessment accuracy decreases
Solution Approach 1:
The database stores soundness determination results covering multiple building types, damage locations, and damage patterns in a unified structure. This universal database can retrieve relevant historical cases regardless of specific building characteristics, enabling accurate structural safety assessment while maintaining inspection efficiency through automated pattern matching.

AI summary
A search unit acquires a type of damage and a degree of damage for each member position obtained in a damage information extraction process of a damage information extraction device. The search unit collates building structure information of a building structure information DB, the degree of damage corresponding to the type of damage for each member position analyzed by an inspection data analysis unit, and use environment history information of a use environment history information DB with soundness information of a soundness DB and searches for soundness of a building similar thereto. A soundness determination unit determines soundness of a building that is an inspection target on the basis of the soundness of the building that has been searched for. A soundness output unit outputs the soundness to a display, a printer, or the like.
