Plug-In Fluid Connection Locking for Vibration-Safe Fire Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug-in connection systems for fluid-conducting components, such as those in fire extinguishing systems, face issues with unreliable locking mechanisms that can inadvertently release due to vibrations, and it is difficult to ensure the correct length of the locking element, leading to potential system failures and hydraulic bursting strength issues.
Innovation Solution
A plug-in connection system with a locking element safety device that includes a retainer and interlock mechanism to prevent accidental release and ensure correct length engagement, featuring a spring-loaded safety element and corresponding fitting members to secure the locking element reversibly and prevent incorrect usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking element is used to secure components together, then the connection reliability is improved, but the locking element can inadvertently release due to vibrations and slip out of the locking element channel
Solution Approach 1:
The locking element is divided into multiple individual locking elements, each engaging with corresponding locking element channels in the first and second components. This segmentation allows each locking element to be independently secured, preventing inadvertent release while maintaining overall connection reliability.
Solution Approach 2:
The locking elements are pre-installed in the locking element channels before the components are fully assembled. This preliminary action ensures that the locking elements are already positioned and secured, preventing them from slipping out during subsequent assembly or operation.
2Ease of operation
If the locking element channel is made accessible for quick installation, then the ease of operation is improved, but it becomes difficult to verify the correct length of the locking element
Solution Approach 1:
Visual indicators such as color-coded markings or transparent sections are incorporated into the locking element channel or locking elements themselves. These visual cues allow operators to quickly verify the correct length and type of locking element during installation, maintaining both installation speed and verification accuracy.
3Ease of operation
If the locking mechanism is simplified for quick release, then the ease of operation is improved, but the risk of accidental release increases
Solution Approach 1:
The locking element channels are designed with dynamic characteristics that allow the locking elements to be easily inserted and removed when intentionally actuated, while simultaneously providing mechanical constraints that prevent accidental release. The channels may include features such as tapered entry sections for easy insertion and retention sections that require deliberate force or action for release.

AI summary
A plug-in connection system for fluid-conducting components of fire extinguishing systems that has a first component having an outer peripheral surface and a first recess in the peripheral surface, and a second component having an inner peripheral surface and a second recess in the inner peripheral surface, wherein the first and the second component can be plugged into one another such that the recesses lie opposite one another and define a locking element channel. A locking element which can be inserted into the locking element channel until an interlock position is reached and at least part of which engages in both recesses in the interlock position. A locking element safety device is provided for reversibly releasably securing the locking element on the first and/or second component.
