Bagging Ring Coating for Filter Housing Seal Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bag-to-bagging ring seals in contamination housing assemblies for hazardous environments lack sufficient integrity, particularly when dealing with severe biomedical, radiological, and carcinogenic contaminants, necessitating an improvement in the seal's integrity to prevent leakage and exposure.
Innovation Solution
A housing assembly with a bagging ring coated with materials that enhance adhesion, such as tacky or statically attractive materials, to improve the seal between the plastic bag and the bagging ring, ensuring a secure and leak-proof connection during filter replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional bagging rings are used without special coating, then the device complexity is low, but the seal integrity between the plastic bag and bagging ring is insufficient
Solution Approach 1:
The patent applies parameter changes by coating the bagging ring with materials that have specific surface properties (tacky or statically attractive) to enhance the seal integrity. This changes the physical-chemical parameters of the bagging ring surface, enabling better adhesion to the plastic bag without fundamentally altering the device structure.
Solution Approach 2:
The patent uses composite materials by combining the bagging ring base material with a specialized coating layer. The coating material (tacky or statically attractive) is applied to the bagging ring surface to create a composite structure that provides both structural integrity and enhanced sealing properties.
2Object-affected harmful factors
If no enhanced seal material is used, then the manufacturing process is simple, but leakage prevention capability is insufficient for severe contaminants
Solution Approach 1:
The patent changes the surface parameters of the bagging ring by applying a coating with tacky or statically attractive properties. This modification enhances the seal's ability to prevent leakage of severe contaminants while maintaining a relatively simple manufacturing process that involves coating the existing bagging ring.
3Reliability
If a plastic bag seal is used without enhancement, then the device complexity is low, but the containment integrity under hazardous conditions is insufficient
Solution Approach 1:
The patent enhances containment integrity by changing the surface parameters of the bagging ring through coating with tacky or statically attractive materials. This creates a more reliable seal between the plastic bag and bagging ring, improving containment of hazardous materials without significantly increasing device complexity.
Solution Approach 2:
The patent employs composite materials by combining the bagging ring structure with a specialized coating layer that provides enhanced adhesion. This composite approach improves containment integrity under hazardous conditions while maintaining the fundamental simplicity of the bagging ring design.
