Detector Module Concave Support for Reduced Module Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional photon counting detectors face challenges in reducing the distance between adjacent detector modules due to mechanical stress and squeezing of flexible boards, leading to reduced data collection performance and reliability.
Innovation Solution
The detector module design incorporates a concave structure in the supporting component to accommodate at least a portion of the flexible board, allowing it to be located on the opposite side of the basal board, thereby reducing the distance between adjacent modules and minimizing squeezing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flexible board is positioned in a conventional manner without accommodation structures, then the assembly is simpler, but the distance between adjacent detector modules increases and the flexible board is subjected to mechanical stress and squeezing
Solution Approach 1:
The flexible board is nested within the concave structure of the supporting component, allowing it to be accommodated in a recessed space rather than protruding outward. This nesting approach reduces the overall distance between adjacent detector modules while protecting the flexible board from mechanical stress and squeezing forces.
Solution Approach 2:
The concave structure introduces a vertical dimension to the supporting component, creating a recessed space that accommodates the flexible board. This dimensional change allows the flexible board to be positioned in three-dimensional space rather than requiring additional horizontal distance, thereby reducing the footprint and distance between adjacent modules.
2Productivity
If the distance between adjacent detector modules is reduced, then the data collection performance improves, but the flexible board is subjected to increased mechanical stress and squeezing
Solution Approach 1:
By nesting the flexible board within the concave structure, the design enables reduced spacing between adjacent modules without subjecting the flexible board to excessive mechanical stress. The concave structure provides physical protection and proper positioning, allowing the flexible board to withstand the closer proximity of adjacent modules while maintaining reliability.
Solution Approach 2:
The concave structure acts as a protective cushioning element that anticipates and mitigates the mechanical stress and squeezing forces that would otherwise be applied to the flexible board when modules are positioned close together. This beforehand cushioning allows for reduced inter-module distance while preserving flexible board integrity.
3Length of stationary object
If the flexible board is accommodated in a concave structure, then the distance between adjacent modules is reduced and squeezing is minimized, but the supporting component becomes more complex
Solution Approach 1:
The concave structure is integrated directly into the supporting component as a unified element, merging the support function with the accommodation function. This combination eliminates the need for separate accommodation structures or additional components, thereby reducing overall system complexity while achieving the goal of reduced inter-module distance.
Solution Approach 2:
The supporting component is designed with multi-functionality, serving both as a structural support element and as an accommodation structure for the flexible board. The concave structure simultaneously provides mechanical support and spatial accommodation, reducing the need for additional specialized components and simplifying the overall device architecture.
