Radiation Shielding Element Wrinkle Prevention via Gas Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiation protection elements with plastic-containing covers often experience undesirable wrinkling, which complicates assembly and can promote oxidation processes, making it difficult to ensure correct positioning of the radiation protection material.
Innovation Solution
A method involving the arrangement of radiation protection material between two layers of plastic-containing elements, with gas removal through pressing or creating a partial vacuum, and connecting them in a protective gas atmosphere to reduce internal gas pressure and prevent wrinkling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radiation protection material is placed inside a plastic casing, then the material is protected and hygiene is improved, but wrinkles form on the outer surface of the casing
Solution Approach 1:
The invention extracts the harmful element (air/gas) from the casing interior by creating a partial vacuum, removing the medium that causes wrinkles to form on the casing surface
Solution Approach 2:
The invention changes the physical parameter of gas pressure inside the casing from atmospheric pressure to reduced pressure (partial vacuum), which prevents wrinkle formation while maintaining the protective function of the casing
2Ease of manufacture
If air pockets are present in the casing, then the casing can be easily manufactured, but oxidation processes are promoted in the radiation protection material
Solution Approach 1:
The invention creates an inert environment inside the casing by removing air and replacing it with a protective gas atmosphere or maintaining partial vacuum, preventing oxidation of the radiation protection material while still allowing for practical manufacturing
3Ease of operation
If the casing is not tightly fitted to the radiation protection material, then assembly is simpler, but it is difficult to determine correct positioning of the material
Solution Approach 1:
The invention applies preliminary action by creating the partial vacuum and bonding the casing layers together during the assembly process itself, ensuring tight fit and correct positioning are achieved as part of the manufacturing process rather than requiring separate adjustment steps
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution reduces the risk of wrinkling and oxidation, facilitating easier assembly and ensuring correct positioning of the radiation protection material, while maintaining a snug fit against the material for enhanced protection.
Implementation Method 1
At least a portion of the gas present between the at least two layers can be removed. This can be done, for example, by pressing one or both of the layers together or by creating a partial vacuum.
Implementation Method 2
The at least two layers, with the at least one radiation protection material arranged therebetween, can be introduced into a protective gas atmosphere. The at least two layers are then bonded together. The protective gas atmosphere can have a lower oxygen content than air.

AI summary
To manufacture a radiation shielding element, a radiation shielding material (10) is arranged between at least two layers (21, 22) of at least one plastic-containing element. At least a portion of the gas present between the at least two layers (21, 22) is removed. The at least two layers (21, 22) are then joined together.
