Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray inspection apparatuses require manual selection of image processing procedures by experts, making it difficult for non-experts to perform accurate inspections as the procedures need to be tailored to specific types of articles, and the process is time-consuming.
Innovation Solution
An X-ray inspection apparatus that automatically selects the most appropriate image processing procedure based on the adaptability of each procedure to the X-ray image, using a method that involves providing multiple procedures, calculating their adaptability, and randomly combining image processing components to create optimized procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual selection of image processing procedures is used, then expert judgment can be applied to optimize detection accuracy, but operation complexity increases and non-experts cannot perform accurate inspections
Solution Approach 1:
The system automatically selects and optimizes image processing procedures without requiring expert intervention. The control unit autonomously determines the appropriate processing procedure based on the inspected article type, enabling any operator to perform accurate inspections regardless of expertise level.
Solution Approach 2:
The system changes the parameter of procedure selection from manual to automatic. By implementing automated parameter determination based on article type, the system eliminates the need for operator expertise while maintaining optimal detection accuracy for different inspected articles.
2Adaptability or versatility
If multiple image processing procedures are provided for different article types, then adaptability to various samples improves, but the time required to select and setup procedures increases
Solution Approach 1:
The system performs preliminary determination of the appropriate image processing procedure based on the inspected article type before actual inspection begins. This pre-selection eliminates the need for real-time procedure selection during inspection, reducing setup time and improving efficiency.
Solution Approach 2:
The system uses feedback about the inspected article type to automatically determine the appropriate processing procedure. By continuously monitoring and using this information to guide procedure selection, the system achieves both adaptability to different articles and rapid setup without manual intervention.
3Ease of operation
If automated selection of image processing procedures is implemented, then ease of operation improves for non-experts, but the complexity of the control system increases
Solution Approach 1:
The control unit serves multiple functions: it controls the X-ray irradiation, processes the received signals, determines the appropriate image processing procedure based on article type, and executes the inspection. By consolidating these functions into a single multi-functional control unit, the system achieves ease of operation without proportionally increasing overall system complexity.
