Nozzle Guide Filtration Element for Clean Medical Gas Sockets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid distribution sockets for medical gases and vacuum in hospitals require improved maintenance and filtration capabilities, including easy disassembly and replacement of worn parts, as well as effective filtration to prevent dust and contaminants from entering the fluid supply.
Innovation Solution
A filtration element for the tip guide of a fluid distribution socket, featuring a support part with lateral openings covered by gas filtration membranes, which can be fixed or removable, made from polymer or metal fabrics with specific pore sizes to filter gases or vacuum, integrated into the socket's design to ensure cleanliness and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the nozzle guide is made as a single integrated component, then structural strength and sealing are improved, but maintenance difficulty increases and part replacement requires complete disassembly
Solution Approach 1:
The nozzle guide is divided into multiple separable components: a body portion, a tip portion, and a filtration element that can be independently removed and replaced. This segmentation allows maintenance of individual parts without disassembling the entire assembly, resolving the contradiction between structural integrity and ease of repair.
2Reliability
If filtration membranes are integrated into the nozzle guide structure, then filtration effectiveness is improved, but device complexity increases
Solution Approach 1:
The filtration element is merged with the nozzle guide structure such that the membrane is positioned within the tip portion and secured by retention features. This integration provides effective filtration while maintaining relatively simple device architecture, as the filtration function is combined with the existing nozzle guide components rather than adding separate complex filtration systems.
3Stability of the object's composition
If the nozzle guide components are permanently fixed together, then structural stability is improved, but ease of disassembly for maintenance deteriorates
Solution Approach 1:
The connection between nozzle guide components transitions from permanent to dynamic/reversible. Retention features such as snap-fit mechanisms or threaded connections allow the tip portion and filtration element to be securely fixed during operation (providing structural stability) while enabling easy disassembly when maintenance is required (improving ease of operation).
