Radiation Imaging Housing Buffer Member Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation imaging apparatuses face challenges in reducing both breakage and deformation when subjected to impact, as high elastic modulus materials can lead to stress concentration and breakage, while lower elastic modulus materials fail to minimize deformation effectively.
Innovation Solution
A radiation imaging apparatus with a housing featuring a buffer member that includes a first portion fixed inside the housing and a second portion protruding outside, where the elastic modulus of the second portion is lower than the housing, effectively distributing impact and reducing deformation and breakage by absorbing shocks at the corners.

Engineering Contradiction Analysis
1Stability of the object's composition
If the outer shell is formed from a material having a high elastic modulus, then the deformation of the overall housing is reduced, but stress concentrates on the outer shell which may break it
Solution Approach 1:
The patent applies local quality by using a dual-material construction where the outer shell and inner shell are made of different materials with different elastic moduli. The outer shell uses a material with higher elastic modulus to resist deformation, while the inner shell uses a material with lower elastic modulus to absorb stress and prevent breakage. This localized differentiation of material properties resolves the contradiction between reducing deformation and preventing breakage.
Solution Approach 2:
The patent employs composite materials by combining two different materials in the housing structure. The outer shell is made of a material with high elastic modulus (e.g., metal or rigid plastic) to maintain structural integrity and resist deformation, while the inner shell is made of a material with low elastic modulus (e.g., foam or rubber) to absorb impact energy and reduce stress concentration. This composite approach allows the housing to simultaneously achieve both deformation resistance and breakage prevention.

If the elastic modulus of the outer shell is decreased, then stress concentration and breakage are reduced, but the deformation of the overall housing increases
Solution Approach 1:
The patent applies local quality by using a dual-material construction where the outer shell and inner shell are made of different materials with different elastic moduli. The outer shell uses a material with higher elastic modulus to resist deformation, while the inner shell uses a material with lower elastic modulus to absorb stress and prevent breakage. This localized differentiation of material properties resolves the contradiction between reducing deformation and preventing breakage.
Solution Approach 2:
The patent employs composite materials by combining two different materials in the housing structure. The outer shell is made of a material with high elastic modulus (e.g., metal or rigid plastic) to maintain structural integrity and resist deformation, while the inner shell is made of a material with low elastic modulus (e.g., foam or rubber) to absorb impact energy and reduce stress concentration. This composite approach allows the housing to simultaneously achieve both deformation resistance and breakage prevention.
3Strength
If a shock absorber is attached to the outer surface of the housing, then breakage is reduced, but the dropping impact is transmitted to the housing through the shock absorber which may distort or deform the overall housing
Solution Approach 1:
The patent merges the shock absorption function directly into the housing structure by making the inner shell an integral part of the housing rather than attaching it as a separate component. The inner shell is formed as a unified structure with the outer shell, creating a composite housing where the low elastic modulus material is permanently integrated to absorb impact energy without being transmitted to the outer shell, thereby preventing both breakage and deformation.
Solution Approach 2:
The inner shell acts as an intermediary between the external impact and the outer shell. When impact occurs, the inner shell with low elastic modulus absorbs and dissipates the impact energy, preventing it from being transmitted to the outer shell. This intermediary structure resolves the contradiction by blocking the transmission path of impact forces while maintaining the overall housing integrity.

AI summary
A radiation imaging apparatus includes a radiation detection panel, a housing configured to accommodate the radiation detection panel, and a buffer member. The housing has an opening in a corner. The buffer member includes a first portion fixed inside the housing and a second portion protruding from the opening of the housing to an outside of the housing. An elastic modulus of the second portion of the buffer member is lower than an elastic modulus of a portion of the housing which forms the opening.
