Adjustable Shield Cover for Radiation Source Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiation source machines emit X-rays that are not fully utilized, leading to unnecessary exposure and potential damage to humans due to unshielded radiation.
Innovation Solution
A shield cover for radiation source machines comprising a frame body, end cover, and connecting member that allows adjustable positioning to shield unused X-rays while allowing intended rays to reach the object of detection, preventing human exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the radiation source machine emits X-rays with a large radiation surface, then the detection coverage is improved, but unnecessary radiation exposure to humans occurs due to unused rays
Solution Approach 1:
The patent extracts and removes the harmful unused radiation from the system by introducing a shield cover that blocks rays that do not reach the detector, allowing only useful radiation to pass through to the object being inspected
Solution Approach 2:
The shield cover acts as an intermediary element between the radiation source and the surrounding environment, selectively allowing useful rays to pass while blocking harmful unused radiation through the shielding material
2Object-affected harmful factors
If a shield cover is added to block unused radiation, then radiation exposure to humans is reduced, but the device complexity increases
Solution Approach 1:
The shield cover is segmented into multiple components including a cover body, connecting members, and adjustment mechanisms, allowing for modular assembly and easier installation while maintaining effective radiation shielding
Solution Approach 2:
The shield cover incorporates movable connecting members that allow the cover to be adjusted and positioned dynamically, enabling easy installation and removal while maintaining a relatively simple overall structure
3Object-affected harmful factors
If the end cover is fixedly connected to the frame body, then the shielding effect is improved, but the positioning accuracy of the radiation source machine decreases
Solution Approach 1:
The connecting members are designed to be movable rather than fixed, allowing the end cover to be adjusted to different positions. This dynamic connection enables both effective shielding when closed and accurate positioning when adjusted, resolving the contradiction between fixed shielding and precise positioning

AI summary
The present disclosure relates to a shield cover for a radiation source machine and a security inspection apparatus. The shield cover for a radiation source machine comprises: a frame body provided with a receiving chamber for receiving the radiation source machine, an end opening and an ray exit through which rays are emitted out from the radiation source machine; an end cover disposed at the end opening of the frame body and provided with a sealed chamber communicating with the receiving chamber; and a connecting member disposed between the end cover and the frame body and provided with an opening for communicating the sealed chamber of the end cover with the receiving chamber of the frame body, and the end cover being movably connected to the frame body by the connecting member such that a distance of the end cover from the end opening of the frame body is adjustable.
