Plug-In Fluid Connection Locking for Vibration-Safe Interlock
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 determine if the locking element is of the correct length, 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 the locking element is securely engaged, featuring a spring-loaded safety element and fitting members to ensure correct length and alignment, thereby maintaining the interlock function and preventing system failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a locking element is used to secure components together, then the connection speed and ease of assembly are improved, but the reliability of the locking mechanism deteriorates due to inadvertent release from vibrations
Solution Approach 1:
The patent introduces a retainer positioned within the locking element channel that prevents the locking element from being completely removed from the channel due to vibrations or other external forces. The retainer acts as a protective measure in advance, cushioning against the harmful effect of inadvertent release while maintaining the quick connection capability.
2Ease of operation
If the locking element channel is open for quick insertion and removal, then the ease of operation is improved, but the ability to detect locking element length deteriorates
Solution Approach 1:
The patent employs visual indicators (such as colored markings or transparent sections) on the locking element and/or the locking element channel that allow operators to quickly verify the correct length of the locking element during assembly. This visual feedback mechanism enables length detection without complicating the insertion and removal process.
3Ease of repair
If the locking element can be completely removed from the channel, then the ease of repair and maintenance are improved, but the system safety deteriorates due to potential component separation
Solution Approach 1:
The retainer is pre-positioned in the locking element channel to prevent complete removal of the locking element during normal operation or under vibration. This beforehand protective measure ensures system safety is maintained while still allowing controlled removal for maintenance when the retainer is deliberately actuated or bypassed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a highly reliable locking mechanism that prevents accidental release and ensures the correct length of the locking element, maintaining the hydraulic bursting strength and safety of the system, while allowing for quick installation and maintenance.
Implementation Method 1
a spring element which is operatively connected to the interlocking element or to the interlock receiver and which is configured to exert a force, in the interlock position, on the interlocking element or the interlock receiver

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.
