Radiation Detection Device Sheet Material Peeling Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation detection devices face issues with corrosion resistance and scratch resistance, particularly when the protective film covering the outer surface is peeled off, leading to reduced effectiveness.
Innovation Solution
A radiation detection device design where sheet materials cover the outer peripheral surfaces of the front and rear surface members, with a holding portion such as grooves or protruding walls, and a packing mechanism to prevent peeling, using a MgLi alloy support plate and vinyl chloride sheet materials for enhanced corrosion and scratch resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the protective film is provided from the back surface housing portion to the outer surface of the frame body with the end portion exposed to the outside, then the corrosion resistance and scratch resistance are improved, but the protective film is prone to peeling off from the end portion
Solution Approach 1:
The protective film is extended from the outer surface of the frame body onto the inner surface of the back surface housing portion, utilizing the third dimension (depth/thickness direction) to create an overlapping configuration. This dimensional transition ensures that the film cannot peel off at the end portion since it continues inward, effectively eliminating the peeling issue while maintaining corrosion and scratch resistance.
Solution Approach 2:
The protective film is pre-installed to cover not only the outer surface but also extend onto the inner surface of the back surface housing portion before assembly. This preliminary extension ensures that when the housing is assembled, the film is already in position to prevent peeling, and the end portion is secured in advance rather than attempting to prevent peeling after assembly.
2Stability of the object's composition
If the protective film is extended to cover the inner surface of the back surface housing portion, then the peeling is suppressed, but the configuration becomes more complex
Solution Approach 1:
The protective film serves multiple functions simultaneously: it protects the outer surface from corrosion and scratches, prevents peeling by extending inward, and provides continuous protection across the interface between the frame body and back surface housing portion. This multi-functionality eliminates the need for separate peeling prevention structures, thereby reducing overall configuration complexity.
Solution Approach 2:
The protective film application is merged with the housing assembly process. The film is installed in such a way that its extension onto the inner surface of the back surface housing portion is integrated into the overall housing structure, rather than being a separate additional component. This merging approach simplifies the overall configuration by combining protection and peeling prevention into a single integrated solution.

AI summary
Provided are a radiation detection device, in which the peeling of a sheet material that covers the outer peripheral surface can be suppressed, and a method of manufacturing a radiation detection device. A radiation detection device includes: a front surface member; a rear surface member assembled with the front surface member; a radiation detection panel disposed between the front surface member and the rear surface member and detecting radiation incident from the front surface member side; a sheet material that covers an outer peripheral surface of at least one of the front surface member or the rear surface member; a packing, the sheet material being interposed between the packing and the front surface member or the rear surface member; and a holding portion provided in at least one of the front surface member or the rear surface member and holding the packing in a pressed state.
