Article Inspection Threshold Setting by Material Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional article inspection apparatuses require a heavy burden of setting determination criteria for each article type, especially when dealing with similar articles or frequent changes in article types, and when multiple inspection areas are designated, leading to increased complexity in setting determination thresholds.
Innovation Solution
An article inspection apparatus that includes an information storage unit, article image capturing unit, configuration determination unit, and proposal output unit to estimate detection sensitivity based on material configuration, reducing the burden of setting determination criteria by proposing suitable thresholds automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If determination criteria are manually set for each article type, then inspection sensitivity can be optimized, but the setting burden increases significantly
Solution Approach 1:
The system performs self-service by automatically determining material configurations through image recognition and calculating appropriate determination criteria without requiring manual operator intervention. The configuration determination unit automatically identifies article types and their material compositions, then the proposal output unit generates suitable inspection criteria based on this automated analysis, eliminating the need for operators to manually set parameters for each article type.
Solution Approach 2:
The system changes parameters dynamically by adjusting determination criteria based on the detected material configuration of each article type. Instead of using fixed manual settings, the system automatically modifies inspection parameters such as threshold values and detection sensitivity levels according to the specific material properties identified through image analysis, allowing optimized inspection settings to be applied automatically without manual reconfiguration.
2Area of stationary object
If multiple inspection areas are designated, then detection coverage increases, but the complexity of setting determination thresholds increases
Solution Approach 1:
The system applies universality by using a single unified determination criterion setting mechanism that works across all designated inspection areas. The configuration determination unit identifies the material configuration for the entire article, and the proposal output unit generates determination criteria that are universally applicable to all inspection areas, eliminating the need to set separate thresholds for each area while maintaining comprehensive coverage.
Solution Approach 2:
The system merges the determination criterion setting into a single unified process rather than requiring separate settings for each inspection area. By combining the material configuration determination and criterion generation into one integrated operation, the system reduces the complexity of managing multiple area-specific thresholds while maintaining comprehensive inspection coverage across all designated areas.

AI summary
An article inspection apparatus inspects a workpiece W including a plurality of ingredients Wa, Wb, Wc, and Wd by using an inspection image of the workpiece. The article inspection apparatus includes an X-ray image memory 61 that stores information of a predetermined detection value related to the inspection image, a configuration determination unit 53 that determines a material configuration of a content in the workpiece W by performing predetermined recognition processing based on image data of the workpiece W obtained by capturing of the camera 41, and a proposal output unit 54 that, when the configuration determination unit 53 determines the material configuration of the content, estimates detection sensitivity to the predetermined detection value based on information stored in the X-ray image memory 61 and a management sensitivity memory 64, and proposes and outputs a determination criterion for an article inspection.
