Inspection Reference Range Adjustment for Determination Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inspection systems face challenges in accurately determining product quality due to determination errors, where products with defects are incorrectly classified as good and vice versa, requiring manual adjustment of reference ranges based on displayed measurement values.
Innovation Solution
An inspection apparatus that adjusts reference ranges based on measurement values of inspection objects with determination errors, displaying occurrence probabilities of errors and allowing for graphical input to update reference ranges, thereby reducing manual intervention and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the reference range is manually adjusted by checking displayed measurement values, then the determination accuracy can be improved, but the time consumption and operational complexity increase
Solution Approach 1:
The inspection apparatus automatically adjusts the reference range by analyzing measurement values from inspection objects with determination errors, eliminating the need for manual intervention. The system identifies patterns in erroneous measurements and self-corrects the reference range, making the adjustment process autonomous and time-efficient
Solution Approach 2:
The system utilizes feedback from determination errors to automatically refine the reference range. By analyzing which inspection objects were misclassified and their corresponding measurement values, the system adjusts the reference range to prevent future errors, creating a continuous self-improving loop
2Measurement precision
If the reference range is manually adjusted by checking displayed measurement values, then the determination accuracy can be improved, but the operational complexity increases
Solution Approach 1:
The inspection apparatus performs automatic reference range adjustment without requiring user intervention. The system independently identifies determination errors, analyzes the corresponding measurement values, and adjusts the reference range automatically, simplifying the operation to a single action while maintaining high accuracy
Solution Approach 2:
The system introduces an automatic adjustment mechanism that acts as an intermediary between the measurement data and the reference range setting. This intermediary process analyzes determination errors and automatically modifies the reference range, eliminating the need for users to manually interpret measurement values and adjust settings
3Reliability
If determination errors occur in inspection objects, then the reliability of quality assessment decreases, but manual adjustment requirements increase system complexity
Solution Approach 1:
The system implements a feedback mechanism where determination errors are automatically detected and used to adjust the reference range. This closed-loop approach continuously improves reliability by learning from past errors, maintaining high quality assessment accuracy without adding complex manual intervention procedures
Solution Approach 2:
The inspection apparatus autonomously handles determination errors by automatically analyzing misclassified inspection objects and adjusting the reference range accordingly. This self-correcting capability maintains high reliability while keeping the system simple, as the automatic adjustment process is integrated into the existing inspection workflow

AI summary
According to the disclosure, an inspection apparatus determines whether a defect has occurred in a plurality of first inspection objects by comparing a reference range with the measurement value of the plurality of first inspection objects, identifies a plurality of second inspection objects in which a first error has occurred, and a plurality of third inspection objects in which a second error has occurred based on a result of determination whether the defect has occurred, adjusts the reference range based on measurement values of the plurality of second and third inspection objects, determines at least one of an occurrence probability of the first error and the second error based on the adjusted reference range, and displays at least one of a graph indicating the result of determination whether the defect has occurred, the adjusted reference range, the determined occurrence probability of the first error and the second error.
