Radiation Imaging Shielding via Buffer-Mounted Conductive Member
Solution Overview
Problem
Existing radiation imaging apparatuses face challenges in impact resistance due to direct fixation of electromagnetic shields, which can break under external impacts, compromising their ability to effectively reduce radiation noise.
Innovation Solution
A radiation imaging apparatus design featuring a buffer member between the imaging panel and the housing, with an electrically conductive member fixed to the buffer member, where the edge of the conductive member surrounds the effective region, enhancing impact resistance and reducing radiation noise by creating a larger closed circuit for eddy current reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the electromagnetic shield is directly fixed to the housing, then the radiation noise reduction is effective, but the impact resistance deteriorates and the shield may break under external impacts
Solution Approach 1:
A buffer member is introduced as an intermediary component between the housing and the electrically conductive member. This buffer member absorbs external impacts and prevents them from being transmitted to the conductive member, thereby maintaining both the radiation noise reduction function and the impact resistance of the overall structure.
Solution Approach 2:
The buffer member is positioned in advance between the housing and the conductive member to provide cushioning protection. This pre-positioned cushioning structure is designed to absorb external impacts before they can damage the conductive member, ensuring continuous operation and preventing breakage.
2Object-affected harmful factors
If the electrically conductive member is made larger to improve radiation noise reduction, then the shielding effectiveness increases, but the device complexity and space requirements increase
Solution Approach 1:
The buffer member serves multiple functions: it provides mechanical cushioning against impacts and simultaneously supports the electrically conductive member. This multi-functionality allows the conductive member to be optimized for radiation noise reduction without adding separate support structures, thereby reducing overall device complexity.
