Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-radiation systems are limited in analyzing complex formed objects, such as car bodies, due to the fixed positioning of the radiation source and detector, which restricts the ability to examine the spatial structure of objects like welding seams through tomography, as the object must be moved between the source and detector, limiting the accessible region for analysis.
Innovation Solution
A method and system where the radiation source is moved relative to the object by rotating about two axes that enclose an acute angle, allowing the central beam to be directed onto a radiation detector, enabling illumination of the object from different directions and improving the analysis of complex objects' spatial structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the radiation source and detector are fixedly disposed at a support, then the system structure is simple and stable, but the ability to analyze complex formed objects is limited
Solution Approach 1:
The radiation source is made movable relative to the object through a positioning device that enables rotation about a first axis and tilting about a second axis. This dynamic configuration allows the radiation source to be positioned at multiple angles and locations, enabling comprehensive analysis of complex formed objects while maintaining a relatively simple overall system structure.
2Measurement precision
If the object must be moved relative to the radiation source and detector for tomography, then spatial structure analysis is possible, but the accessible region is limited
Solution Approach 1:
Instead of moving the object, the radiation source is moved in multiple dimensions through rotation about a first axis and tilting about a second axis. This multi-dimensional positioning capability allows the radiation source to approach the object from various angles and positions, significantly expanding the accessible region for analysis while maintaining precise spatial structure measurement capability.
3Adaptability or versatility
If the radiation source is moved to illuminate the object from different directions, then comprehensive spatial analysis is enabled, but the positioning complexity increases
Solution Approach 1:
The positioning device incorporates dynamic elements including rotation about a first axis and tilting about a second axis, allowing the radiation source to be moved to various positions and orientations. This dynamic design enables comprehensive illumination of the object from different directions while maintaining a manageable level of complexity through integrated mechanical design.
