Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quality evaluation devices do not account for the usage state of components, leading to low accuracy in evaluating their quality.
Innovation Solution
A quality evaluation method and device that extracts feature amounts from defect detection information, specifies evaluation target sites, and determines aggressive defects based on usage state information, using non-destructive inspection methods like X-ray or ultrasonic waves, to assess component quality according to specific usage conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If quality evaluation is performed using only defect detection without considering usage state, then the evaluation process is simple, but the accuracy of quality evaluation is low
Solution Approach 1:
The patent introduces usage state parameters (such as operating conditions, environmental factors, and functional requirements) as additional variables to the defect detection process. By changing the evaluation parameters from solely defect-based to usage-state-inclusive parameters, the system achieves more accurate quality evaluation while maintaining a structured approach through standardized parameter sets.
Solution Approach 2:
The patent segments the quality evaluation process into distinct modules: defect detection module, usage state information acquisition module, and quality evaluation module. This segmentation allows each module to handle specific tasks independently, improving overall accuracy while keeping the system architecture manageable and organized.
2Reliability
If defect evaluation does not consider site-specific usage states, then the evaluation method is straightforward, but it cannot accurately assess component reliability
Solution Approach 1:
The patent applies local quality by evaluating defects at specific sites within the component based on the usage state of each particular location. Instead of uniform evaluation, the system considers site-specific factors such as stress distribution, operational load, and environmental exposure at each defect location, thereby improving reliability assessment accuracy.
Solution Approach 2:
The patent introduces usage state information as an intermediary element that bridges defect detection and reliability assessment. This intermediary parameter set translates operational context into evaluative criteria, enabling the system to connect physical defect characteristics with functional reliability expectations without requiring direct complex interaction between all system components.

AI summary
A quality evaluation device operates to: detect a defect present in a component based on a detection result obtained by a non-destructive inspection method; extract feature amounts of the defect from detection information of the defect; specify an evaluation target site in which the defect is present in the component; acquire one or more usage state information values associated with the evaluation target site, the usage state information values being estimated values that represent physical characteristics of the evaluation target site when the component is used; and determine, based at least on the feature amounts and the one or more usage state information values, whether or not the defect is an aggressive defect.
