Gas Cartridge Adapter With Hinged Fixing Legs

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing gas cartridge adapters require significant effort to eject the cartridge from its housing due to the need for a single thrust to break the cooperation between the adapter and the intermediary nose piece, making the process cumbersome.

Innovation Solution

The adapter features hinging fixing legs that rotate and open before translating, allowing for easier disconnection and ejection by first releasing the adapter from the intermediary nose piece, reducing the required ejecting effort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the adapter uses a single thrust mechanism to break the cooperation between the adapter and the intermediary nose piece, then the connection is secure and reliable, but the ejection process requires significant effort and becomes cumbersome

Engineering Contradiction:

Improveconnection reliabilityVSAvoidejection ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The fixing legs are designed to be hinged rather than rigid, allowing them to dynamically change from a closed fixed position during connection to an open released position during ejection. This dynamic transformation enables the same structure to provide both secure connection and easy ejection without requiring excessive force.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The ejection process is segmented into two distinct phases: first the hinged fixing legs rotate to open and release the intermediary nose piece, then the cartridge translates along the guide ribs. This segmentation separates the breaking of cooperation from the ejection motion, making the overall process easier to execute.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If the fixing legs are rigid and fixed, then the structural simplicity is maintained, but the ejection process requires a single large thrust and significant effort

Engineering Contradiction:

Improveadapter structure simplicityVSAvoidejection force

Core Design Contradiction:

Device complexityVSForce

Solution Approach 1:

The fixing legs incorporate a hinge mechanism that allows them to rotate from a closed position during connection to an open position during ejection. This dynamic feature enables the structure to adapt its configuration based on the operational phase, reducing the force needed for ejection while maintaining connection integrity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The hinged fixing legs are pre-configured to automatically open in response to the ejection motion, creating a preliminary release action that reduces the resistance force during cartridge removal. This preliminary anti-action prevents the need for a single large thrust force.

Inventive Principle:

Principle #9Preliminary anti-action

AI summary

The adapter comprises a central tubular body extending on one side with an abutment and fixing base on the cartridge and, on the other side, with two fixing legs on an intermediary nose piece of the transmission and filling member able to be hinged for ensuring the fixing operation, disconnecting and ejecting wings being additionally provided. The disconnecting and ejecting wings are arranged for opening the fixing legs before driving them into translation.
