Gas Cylinder Quick-Release Coupling for Emergency Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In emergency situations, such as a fire near a gas cylinder in a motorhome, the secure removal of the cylinder from its housing is hindered by the need for a wrench to loosen the screw connection between the cylinder and the filling hose, making rapid evacuation difficult and potentially dangerous.
Innovation Solution
A quick-release coupling system is integrated into the gas container, allowing detachment without tools, featuring a bayonet fitting or a ball and sleeve mechanism for easy disconnection, ensuring rapid removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gas cylinder is securely screwed to the filling hose with a wrench-tightened connection, then the connection is leak-proof and reliable, but the gas cylinder cannot be rapidly removed in emergency situations
Solution Approach 1:
The coupling connection is divided into two separate coupling elements: one screwed onto the filling port thread and the other firmly connected to the filling hose. This segmentation allows the connection to be both secure during normal operation and quickly detachable in emergencies without requiring tools.
Solution Approach 2:
The coupling mechanism transitions from a static screw connection to a dynamic quick-release system. The coupling elements can be easily detached by hand through simple movements (such as twisting bayonet fittings or retracting ball-and-sleeve mechanisms), enabling rapid removal while maintaining connection reliability during normal use.
2Reliability
If a wrench is required to loosen the screw connection, then the connection is secure and leak-proof, but the wrench may not be readily available in emergencies
Solution Approach 1:
The coupling system is designed to be self-servicing, allowing users to detach the connection without external tools. The quick-release mechanism enables hand-operated detachment through intuitive movements, eliminating the need for wrenches or other specialized tools that may not be immediately available.
Solution Approach 2:
The system transitions from requiring manual tool-assisted operation to tool-free hand operation. The coupling elements are designed with mechanical features (such as bayonet fittings or ball-and-sleeve mechanisms) that allow easy detachment through simple twisting or pushing motions, significantly improving ease of operation during emergencies.
3Stability of the object's composition
If the filling hose and filling nozzle are permanently attached to the housing wall, then the installation is stable and secure, but the gas cylinder cannot be quickly evacuated from danger zones
Solution Approach 1:
The connection system is segmented into permanently fixed components (filling nozzle attached to housing wall) and detachable components (coupling elements on the gas cylinder). This allows the installation to remain stable and secure during normal operation while enabling rapid evacuation by simply detaching the coupling elements without disturbing the permanent installations.
Solution Approach 2:
The system combines permanent fixed installations with dynamic detachable connections. The filling hose and nozzle remain firmly mounted to the housing wall for stability, while the coupling elements on the gas cylinder can be quickly released by hand, minimizing evacuation time in emergency situations.

AI summary
A gas container that can be inserted into a housing and is equipped with a multi-function valve comprising a filling stop valve with a filling port, a withdrawal valve, and a level indicator, which are fixedly attached to a flange that is mounted on the gas container, wherein the filling port is connected by a filling line, preferably a filling hose, to a filling nozzle that can be attached to a housing wall and that can be connected to a refueling nozzle of a filling device for filling the gas container, is characterized in that a coupling is connected to the filling port of the gas container, one coupling element of which is screwed onto the thread of the filling port, and the other detachable coupling element is connected to the filling hose.
