Structure Damage Case Presentation for Misdiagnosis-Aware Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diagnostic methods for structural damage are prone to misdiagnosis due to the lack of skilled diagnosticians, leading to suboptimal repairs and decreased cost-effectiveness.
Innovation Solution
A structure diagnostic case presentation device and method that utilizes a processor and database to extract and present specific diagnostic cases with similar damage to the target structure, including misdiagnosed cases, to support more accurate diagnoses by less experienced diagnosticians.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visual observation and hammering examinations are used for structure diagnosis, then diagnostic simplicity is maintained, but misdiagnosis rate increases due to lack of skilled diagnosticians
Solution Approach 1:
An information processing device acts as an intermediary between the diagnostician and the structure diagnosis process. The device captures images of the structure, automatically detects defects using image processing algorithms, and presents diagnostic information to the diagnostician, thereby reducing dependence on the diagnostician's personal skills and experience while maintaining operational simplicity
Solution Approach 2:
The patent replaces manual visual observation and physical hammering examinations with automated image capture and image processing systems. The information processing device uses computational algorithms to detect defects, substituting the mechanical and sensory processes of human diagnosticians with automated electronic systems that provide more consistent and reliable results
2Reliability
If more skilled diagnosticians are trained to reduce misdiagnosis, then diagnosis accuracy improves, but time and resource costs increase
Solution Approach 1:
The information processing device performs self-service by automatically capturing images, processing them through image processing algorithms, and generating diagnostic information without requiring extensive human intervention or training. The system serves itself to provide reliable diagnosis, reducing the need for time-consuming training of human diagnosticians
3Reliability
If automated image processing is used to detect defects, then objectivity of diagnosis improves, but ability to support diagnostic decision-making decreases
Solution Approach 1:
The patent merges automated image processing results with additional diagnostic information presentation. The information processing device not only detects defects objectively through image processing but also presents comprehensive diagnostic information including multiple images, defect locations, and analysis results in an integrated manner that supports the diagnostician's decision-making process

AI summary
Provided are a structure diagnostic case presentation device, method, and program capable of performing support such that a diagnostician can make a more appropriate diagnosis in diagnosing damage of a target structure to be diagnosed. In a case where information (damage information) regarding the target structure to be diagnosed is acquired by a first information acquisition unit (20), a similar damage extraction unit (22-1) extracts similar damage similar to the damage of the target structure from a database (12) based on the acquired damage information. A specific diagnostic case extraction unit (24-1) extracts, as a specific diagnostic case, a diagnostic result that is a diagnostic result of a structure having the extracted similar damage and is a diagnostic result of a structure having different diagnostic results at two points in time or more, from the database (12). Information related to the extracted specific diagnostic case is displayed on a display unit (14).
