Multi-Panel Lead Acrylic Radiation Barrier for Scattered Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation shields provide inadequate protection against radiation exposure from multiple directions, particularly scattered radiation, due to their fixed and single-directional design, leading to cumulative health risks for medical personnel during procedures.
Innovation Solution
A radiation barrier with independently-pivotable shields formed from transparent lead acrylic, allowing adjustable protection by pivoting and positioning to cover multiple directions, including direct and scattered radiation sources, with a support arm and flexible skirt for enhanced coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single fixed radiation shield is used, then the structure is simple and easy to manufacture, but it provides protection only from a single direction and cannot adapt to scattered radiation from multiple directions
Solution Approach 1:
The radiation shield is divided into multiple independent panels that can be individually positioned and adjusted. Each panel can be rotated and angled to face different directions, allowing the system to provide comprehensive multi-directional protection while maintaining relative structural simplicity through modular design.
Solution Approach 2:
The shield transitions from a fixed structure to a dynamic, adjustable system where panels can be rotated, angled, and repositioned during procedures. This allows the shield to adapt to scattered radiation sources moving in different directions while maintaining ease of operation through mechanical adjustment mechanisms.
2Object-affected harmful factors
If lead aprons and protective clothing are worn, then some radiation exposure is reduced, but coverage is incomplete and prolonged exposure remains dangerously toxic
Solution Approach 1:
The adjustable panels serve as intermediary protective structures positioned between the radiation sources and medical personnel. These panels provide substantial radiation blocking capability, acting as a more effective intermediary barrier compared to wearable protective clothing, thereby significantly reducing radiation exposure levels and improving protection reliability.
3Adaptability or versatility
If a single lead plate is mounted on a stand, then the shield is simple and stable, but it cannot provide adjustable protection against radiation from multiple directions
Solution Approach 1:
The shield system is segmented into multiple independently adjustable panels, each capable of being positioned and angled separately. This segmentation enables comprehensive multi-directional coverage while maintaining ease of operation through individual panel adjustment mechanisms that can be independently controlled.
Solution Approach 2:
Each panel in the shield system serves multiple functions: it can be positioned to block direct radiation, angled to intercept scattered radiation from various directions, and repositioned as needed during procedures. This multi-functionality achieves high adaptability while maintaining operational simplicity through versatile mechanical adjustment capabilities.

AI summary
A radiation barrier provides adjustable protection against radiation incident from multiple directions simultaneously. First and second radiation shields are pivotally retained by an axis post to form a radiation shield assembly. Each radiation shield is formed from radiation shielding material with a lead equivalence. The radiation shields have a closed configuration where the shields are disposed in a nesting relationship to a single side of the axis post with the first radiation shield disposed interior to the second radiation shield. The first radiation shield pivots in a plane laterally displaced from the center axis of the axis post by a distance D1 while the second radiation shield pivots in a plane laterally displaced from the center axis by a greater distance D2. Notches can be disposed in the proximal end portion of the first radiation shield to permit mounting brackets of the second radiation shield to be received therethrough.
