Breathing Apparatus Connectors for Magnetic Quick-Release Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current connectors in breathing apparatuses are not designed for rapid assembly, limit component movement, and do not adapt well to movement, leading to stability issues and increased size due to longer connections.
Innovation Solution
The connectors include male and female components with levers, retractable pins, projections, and switches that facilitate easy connection and disconnection, allowing for flexible movement and quick assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cylindrical rubber connectors are used with friction-based connection, then the connection is leakproof and stable, but the assembly is slow and components cannot move freely
Solution Approach 1:
The connector uses a spring-loaded ball mechanism that dynamically adapts to movement between components. The ball engages with a recess to maintain connection during physiological movement while allowing rapid assembly through simple insertion without friction-based coupling
Solution Approach 2:
The invention replaces the friction-based mechanical connection system with a positive locking mechanism using a spring-loaded ball and recess. This substitution enables rapid assembly while maintaining secure, leakproof connection without relying on friction between rubber surfaces
2Stability of the object's composition
If cylindrical rubber connectors are used with friction-based connection, then the connection is stable, but the connector length must be increased to maintain stability, increasing overall device size
Solution Approach 1:
The spring-loaded ball mechanism provides dynamic stability that adapts to movement between components. The spring allows the ball to maintain engagement with the recess during physiological movement while requiring minimal connector length, eliminating the need for long connectors to achieve stability
3Strength
If cylindrical rubber connectors are used, then the connection can maintain structural integrity, but the connectors cannot adapt well to movement of components
Solution Approach 1:
The spring-loaded ball mechanism dynamically adapts to movement between components while maintaining secure connection. The spring allows the ball to remain engaged with the recess during physiological movement, providing both structural integrity and adaptability to component movement
Solution Approach 2:
The spring mechanism changes the physical state of the connection from rigid to compliant, allowing the connector to adapt its parameters (position, force) in response to movement while maintaining the leakproof seal and structural integrity

AI summary
A connection system for connecting gas delivery components of a Continuous Positive Airway Pressure system includes a first conduit with a first lumen forming a first part of a gas flow path for the breathable gas and a second conduit with a second lumen forming a second part of the gas flow path. The ends of each flexible connector include a magnets. The first and second flexible connectors are configured to be joined together to form a sealed connection by way of moving the first and second flexible connectors toward each other in an axial direction and are configured to be held together by a magnetic force between the first and second magnets. In addition, the first and second flexible connectors are configured to be separated from each other by pivoting the first and second connectors relative to each other.
