Helium-3 Tube Array Alignment Mount for Coplanar Detector Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detector arrays face challenges in aligning detector tubes so that their elongate center axes are within a single plane due to sag or dip issues in support frames, often made of materials like aluminum, which can cause variations in mounting precision.
Innovation Solution
The solution involves a support frame with multi-tube detector packs that include mounting tabs with securing and adjusting portions. These tabs have operable securing and adjusting members that allow for precise orientation adjustments, ensuring all detector tubes extend parallel to each other within a common plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If detector tubes are mounted on a support frame made of aluminum, then the support structure is lightweight and easy to manufacture, but the frame experiences sag or dip at different support points causing misalignment of detector tube axes
Solution Approach 1:
The mounting tab includes an adjusting member (threaded rod) that allows dynamic adjustment of the detector pack orientation after installation. By rotating the threaded rod, the detector pack can be precisely positioned to achieve coplanar alignment of all detector tube axes, compensating for frame sag or dip in lightweight aluminum construction.
Solution Approach 2:
The adjusting mechanism changes the positional parameters of the detector pack relative to the support frame. The threaded adjusting member enables fine-tuning of the detector pack orientation by converting rotational motion into linear displacement, allowing precise control over the detector tube axis alignment.
2Stability of the object's composition
If detector tubes are fixed rigidly to the support frame, then the structure is stable and simple, but alignment precision cannot be adjusted to compensate for frame deformation
Solution Approach 1:
The mounting system transitions from a purely rigid fixed connection to a semi-rigid connection with adjustment capability. The securing member provides rigid attachment while the adjusting member introduces controlled flexibility, allowing the detector pack orientation to be dynamically tuned while maintaining overall structural stability during operation.
Solution Approach 2:
The mounting connection is segmented into two functional parts: a securing portion that provides rigid structural attachment and an adjusting portion that enables precise orientation control. This segmentation allows the system to simultaneously achieve both structural stability and alignment precision.
3Device complexity
If all detector tubes are grouped into fixed bundle packs, then the assembly is compact and easy to support, but individual tube alignment within the plane cannot be precisely controlled
Solution Approach 1:
Multiple detector tubes are merged into a single detector pack assembly that moves and aligns as one unit. The mounting tab and adjusting mechanism control the orientation of the entire bundle, simplifying the support structure while maintaining precise alignment of all individual tube axes within the common plane.
