Respirator Connector Bayonet Thread Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Respirator components often become loose or disconnected during use due to insecure fastening, which compromises the effectiveness and safety of the respirator assembly.
Innovation Solution
The respirator assembly incorporates a connector and adaptor with bayonet threads and a gasket, featuring a 50-degree ramp angle that increases friction and torque, ensuring secure engagement between components, making them difficult to disengage accidentally during normal operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fastening methods are used to connect respirator components, then the assembly process is simple, but the components become loose or disconnected during use
Solution Approach 1:
The patent applies parameter changes by modifying the threading geometry with a specific 50-degree ramp angle and incorporating a bayonet thread configuration. This changes the mechanical parameters of the connection interface to provide superior engagement security compared to conventional fastening methods, directly addressing the reliability issue while maintaining reasonable manufacturing complexity
Solution Approach 2:
The bayonet thread configuration utilizes curved engagement surfaces that wrap around the connection interface. This curvature provides mechanical interlocking that prevents loosening during use, transforming the linear fastening approach into a rotational engagement system that secures components more reliably
2Reliability
If secure fastening with bayonet threads and 50-degree ramp angle is implemented, then components remain securely connected, but the manufacturing complexity increases
Solution Approach 1:
By specifying a standard 50-degree ramp angle, the patent establishes a fixed geometric parameter that can be consistently manufactured using conventional machining processes. This standardized parameter balances the need for secure engagement with the practical constraints of manufacturing capability
Solution Approach 2:
The connection system is segmented into distinct functional elements: the bayonet thread for rotational engagement, the 50-degree ramp angle for mechanical locking, and the gasket for sealing. This segmentation allows each element to be manufactured and assembled separately, managing overall manufacturing complexity while achieving high reliability
