Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiographic imaging systems face challenges in adaptively shielding radiation from irradiating to areas outside the imaging target and securing a working space for adjusting the compression part, particularly due to difficulties in adjusting the radiation protection device according to the imaging method and patient's body condition.
Innovation Solution
A radiation protection device with a fixing unit, elevation unit, and shielding unit that is adjustable in height and rotatable, allowing for customizable positioning to shield radiation effectively and secure an operation space during imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed radiation protection device is used, then radiation shielding is provided, but the device cannot be adjusted according to imaging conditions or patient body condition
Solution Approach 1:
The radiation protection device incorporates an elevation unit with a movable block that can slide along guide parts and be positioned at different heights through position fixing holes. This dynamic positioning capability allows the shielding unit to be adjusted according to different imaging conditions and patient body conditions, resolving the contradiction between adaptability and device complexity.
2Object-affected harmful factors
If a radiation protection device is added to shield radiation, then radiation exposure to non-target areas is reduced, but the working space for adjusting the compression part is reduced
Solution Approach 1:
The connecting unit enables the shielding unit to rotate about a rotation axis, allowing the shielding unit to be positioned in different orientations. This rotational capability provides flexibility in positioning the shielding unit to minimize radiation exposure while maintaining adequate working space for compression part adjustment, thus resolving the contradiction between radiation protection and operational ease.
3Object-affected harmful factors
If the shielding unit is made large to cover more area, then radiation shielding effectiveness is improved, but the device becomes harder to adjust and position
Solution Approach 1:
The radiation protection device is divided into distinct functional units: a fixing unit for attachment, an elevation unit for vertical adjustment, and a connecting unit for rotational positioning. This segmentation allows the shielding unit to be independently adjusted in multiple degrees of freedom, making it easier to position large shielding surfaces effectively without compromising adjustability.
4Adaptability or versatility
If the radiation protection device is made adjustable to fit different patients, then adaptability is improved, but the device complexity increases
Solution Approach 1:
The elevation unit employs a simple yet effective mechanism with guide parts, a movable block, and position fixing holes that allow vertical adjustment without complex controls. The connecting unit provides rotational adjustment through a rotation axis. These dynamic components enable adaptation to different patient body conditions while maintaining relatively simple device mechanics.
