Sterilization Container Locking Mechanism for Replaceable Filter Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sterilization containers lack a convenient method for replacing filter media, which is essential for maintaining air filtration quality after reuse.
Innovation Solution
The sterilization container design includes filter retaining plates, clips, seals, and a locking mechanism that allows for easy removal and replacement of filter assemblies, ensuring a clean air transfer and maintaining sterility during and after the sterilization process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If filter assemblies are permanently integrated into the sterilization container, then the container structure is simple and robust, but the filter media cannot be replaced to ensure clean air transfer
Solution Approach 1:
The filter assembly is divided into separate components: a filter holder that attaches to the container and removable filter media that can be replaced. This segmentation allows the filter media to be replaced independently while maintaining a simple container structure.
Solution Approach 2:
The filter assembly incorporates a dynamic attachment mechanism with clips and locking features that allow the filter holder to be easily attached and detached from the container, enabling filter media replacement without permanent integration.
2Ease of operation
If filter assemblies are designed to be removable for replacement, then the filter media can be replaced to maintain sterility, but the container structure becomes more complex
Solution Approach 1:
The filter assembly includes self-locking clips and retention features that automatically secure the filter holder to the container without requiring additional fastening steps or complex mechanisms, enabling easy user operation.
Solution Approach 2:
The attachment mechanism combines multiple functions (securing, sealing, and positioning) into an integrated filter holder assembly that attaches to the container in a single operation, reducing overall system complexity while improving ease of filter replacement.
3Ease of operation
If the container is designed for easy disassembly to replace filters, then filter replacement is convenient, but the sealing and sterility maintenance become more difficult
Solution Approach 1:
The filter holder includes pre-integrated sealing elements and gaskets that are positioned before assembly, ensuring that sterility barriers are in place before the filter media is installed or removed, maintaining sterility throughout the replacement process.
Solution Approach 2:
A sealing interface acts as an intermediary between the removable filter holder and the container body, providing a reliable barrier that maintains sterility while allowing easy attachment and detachment of the filter assembly.

Function Achieved in This Case
This design enables efficient and sterile reuse of the container by allowing for the easy replacement of filter media, ensuring effective air filtration and maintaining the sterility of medical devices during storage and transportation.
Implementation Method 1
air permeable filter assemblies that allow filtered ambient air to enter and exit the container
Implementation Method 2
The pan contains holes that permit the passage of air, moist heat/steam, or other autoclave gases into the container
