Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray nondestructive inspection methods, particularly for products with complex structures, are unable to perform real-time in-line inspections due to the time-consuming nature of three-dimensional computerized tomography equipment, limiting production speed.
Innovation Solution
An X-ray inspection apparatus and method utilizing a transfer unit, multiple X-ray sources arranged in various configurations, and a detection unit to acquire two-dimensional or three-dimensional images of a moving subject in real time, enabling synchronized X-ray radiation and image processing without mechanical rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If three-dimensional computerized tomography equipment is used for inspection, then measurement precision and image quality are improved, but inspection time increases significantly
Solution Approach 1:
The inspection system is divided into multiple independent X-ray sources arranged in parallel, each capturing a specific angular view. This segmentation allows simultaneous multi-angle acquisition without requiring sequential rotation, thereby maintaining high measurement precision while dramatically reducing inspection time
Solution Approach 2:
The system transitions from a single rotating X-ray source to a multi-dimensional array of fixed X-ray sources. By adding spatial arrangement in multiple directions rather than temporal rotation, the system achieves three-dimensional inspection capability in real-time, resolving the contradiction between precision and speed
2Productivity
If a single X-ray source is used, then device complexity is reduced, but productivity and inspection speed decrease
Solution Approach 1:
Multiple X-ray sources are merged into a single inspection system with coordinated control. The sources work simultaneously from different positions, combining their individual capabilities to achieve high-speed three-dimensional inspection while sharing common detection and processing infrastructure
Solution Approach 2:
The system design allows the multi-source array to perform multiple functions: two-dimensional imaging, three-dimensional reconstruction, and real-time inspection. The same hardware configuration adapts to different inspection modes and product types, improving productivity without proportionally increasing complexity
