Radiation Imaging Panel Support With Dual Extending Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation imaging devices lack a stable support structure for the radiation detection panel, which can lead to impact transmission and reduced assembly workability.
Innovation Solution
A radiation imaging device with a base substrate that includes protruding portions and extending portions for stable support, using first and second extending portions to sandwich the base substrate between housing walls, reducing the need for additional support members and enhancing assembly workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the base substrate is supported by additional support members on the back surface, then the support stability is improved, but the number of components increases and impact transmission to the radiation detection panel increases
Solution Approach 1:
The first and second extending portions are integrally formed with the base substrate, merging the support function into the base substrate itself. This eliminates the need for separate support members while maintaining stable support of the radiation detection panel.
Solution Approach 2:
The support function is extracted from separate support members and integrated into the base substrate through the extending portions. This reduces the number of components and prevents impact transmission by eliminating intermediate support structures.
2Strength
If the base substrate is integrally formed with extending portions, then the structural strength is improved, but warpage of the base substrate occurs
Solution Approach 1:
The base substrate is segmented into a main body and separate extending portions. This allows the main body to be formed without warpage while the extending portions provide the necessary structural strength and support functions independently.
Solution Approach 2:
The extending portions are provided only at specific locations where support is needed, rather than forming the entire base substrate as one piece. This localized approach provides structural strength where required while avoiding warpage in the main body.
3Manufacturing precision
If the first extending portion is made larger, then the positioning accuracy is improved, but the device size increases
Solution Approach 1:
The first extending portion is made larger only in the region where positioning is required, while other portions maintain minimal size. This localized enlargement provides the necessary positioning accuracy without significantly increasing the overall device size.
