Adjustable Fixture for 3D X-ray CT Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D X-ray CT devices face challenges in accurately orienting and positioning detected articles, leading to poor detection efficacy and potential damage due to manual and time-consuming adjustment methods.
Innovation Solution
An adjustable fixture structure comprising a connecting bottom base, adjustable connecting element, fixture element, and screw elements that allow for precise sliding and fixation of the detected article within the detection range, enabling convenient orientation and positioning without damaging the article.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of the detected article is performed by repeatedly detaching and repositioning, then the orientation and position can be adjusted, but time is wasted and the article may be damaged
Solution Approach 1:
The fixture structure employs adjustable connecting elements that can slide along the X and Y axes, transforming the static fixture into a dynamic system. The detected article can be positioned at different coordinates without detachment, resolving the contradiction between ease of adjustment and time consumption
Solution Approach 2:
The adjustable connecting elements serve as intermediaries between the base and the detected article. These elements enable smooth transmission of positioning adjustments without requiring direct manual manipulation of the article itself, reducing both time and damage risk
2Ease of operation
If manual adjustment of the detected article is performed by repeatedly detaching and repositioning, then the orientation and position can be adjusted, but the article may suffer careless damage
Solution Approach 1:
The dynamic sliding mechanism allows continuous adjustment of the detected article's position while it remains securely held by the fixture. This eliminates the repeated detachment and reattachment process that causes mechanical stress and potential damage to the article
Solution Approach 2:
The fixture structure provides self-contained adjustment capabilities through its sliding mechanisms, eliminating the need for external manual intervention that could lead to careless damage. The system adjusts itself without requiring the article to be released from the fixture
3Measurement precision
If the detected article deviates from accurate position, then the see-through images are not correct and complete, but manual adjustment is time-consuming
Solution Approach 1:
The adjustable connecting elements with sliding mechanisms enable rapid and precise positioning of the detected article along the X and Y axes. This dynamic adjustment capability allows the article to be accurately positioned within the detection range quickly, improving both positioning accuracy and detection efficiency
Solution Approach 2:
The fixture structure allows preliminary positioning adjustments to be made before the actual detection process begins. The detected article can be pre-positioned at the optimal location and orientation, ensuring accurate imaging from the start and eliminating the need for time-consuming adjustments during detection

AI summary
An adjustable fixture structure for a 3D X-ray CT device is disclosed. Only the detected article is fixed on the fixture element of the adjustable fixture structure, may the adjustable connecting element slide with respect to the adjustable sliding trough and the fixture element slide with respect to the fixture sliding trough, so that the detected article is adjusted into within the detection range of the 3D X-ray CT device by using the adjustable connecting element and the fixture element. As such, the issues which a detected article is difficult to be oriented and positioned, a detection efficacy and result is poor, and the detected article might thus be damaged, may be well overcome.
