Solution Overview

Problem

Existing carbonation machines require complex and potentially damaging procedures for replacing gas canisters, as the traditional threaded connections can lead to overtightening and risk of seal damage, and do not facilitate easy insertion or removal by unskilled users.

Innovation Solution

A gas canister valve adapter with laterally oriented exterior ports and a channel system that allows for fluidic communication between a filling port and exterior ports, enabling easy connection to a filling head without the need for threaded sockets, and a mechanism for simple insertion and removal without generating thrust that could separate the canister from the holder.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional threaded connections are used for gas canister replacement, then secure connection is achieved, but the risk of overtightening and seal damage increases

Engineering Contradiction:
Improveconnection securityVSAvoidseal damage risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The adapter serves as an intermediary component between the gas canister valve and the filling head/carbonation machine. It features a receiving cavity that accepts the canister valve body and provides a sealed connection interface, eliminating the need for direct threaded connections between the canister and machine, thus preventing overtightening damage while maintaining secure connections

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The adapter is designed as a simple, robust component that can be easily replaced if needed. Its straightforward design with basic sealing elements makes it less critical than the main machine components, allowing for potential disposal or replacement without significant cost or complexity

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Reliability

If threaded sockets are used for canister connection, then secure attachment is achieved, but the complexity of replacement procedure increases

Engineering Contradiction:
Improveattachment securityVSAvoidreplacement simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system is segmented into distinct modular components: the gas canister, the adapter, and the filling head/carbonation machine. The adapter acts as an independent module that simplifies the interface between the canister and machine, allowing for tool-free attachment and detachment without complex threading operations

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adapter mediates the connection between the canister valve and the filling head, providing a simple insertion interface that eliminates the need for users to perform complex threading operations. The adapter's receiving cavity accepts the canister valve body through straightforward insertion, making the replacement process accessible to unskilled users

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If lateral exterior ports are used in the valve, then easy connection to filling head is achieved, but thrust during gas release could separate canister from holder

Engineering Contradiction:
Improveconnection easeVSAvoidthrust force
Core Design Contradiction:
Ease of operationVSForce

Solution Approach 1:

The adapter serves as a mediator that absorbs and manages the thrust forces generated during gas release. It features a robust structure with a receiving cavity that secures the canister valve, and the thrust forces are distributed through the adapter's body rather than directly transmitting to the canister-holder interface, preventing separation

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An adapter may comprise a body having an opening that is shaped to enable insertion of a valve of a gas canister that is configured to hold a pressurized or liquefied gas for carbonating a liquid, the valve comprising a canister port to a confined space within the gas canister, the valve also comprising at least one exterior port that opens laterally to the longitudinal axis of the valve; and at least one channel that is configured to conduct pressurized gas from a filling port of a canister filling machine to one or more channels that are in fluidic communication with said at least one exterior port of a valve that is inserted into the opening, wherein the adapter is configured to facilitate filling of the gas canister with the pressurized or liquified gas, while said at least one lateral exterior port is maintained stationary with respect to the gas canister at all times when the valve is inserted within the adapter.
