Carbonation Canister Socket Seal for Quick Gas Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carbonation machines face challenges in efficiently and safely replacing gas canisters, often requiring users to manually screw and unscrew threaded connections, which can lead to overtightening or damage to seals.
Innovation Solution
A carbonation machine design that includes a holder with a socket featuring a seal with lateral openings for fluidic flow, and a holding mechanism to secure the gas canister valve, allowing for linear insertion and removal without threading, and an activation mechanism to operate the valve for gas release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded connections are used for gas canister replacement, then the connection reliability is improved, but the ease of operation deteriorates due to manual screwing requirements and risk of overtightening
Solution Approach 1:
The patent replaces the threaded mechanical connection system with a bayonet-style quarter-turn coupling system. The valve body features external threading that engages with internal threading in the holder, but instead of requiring multiple rotations for tightening, a quarter-turn motion simultaneously achieves both engagement and sealing through the interaction of the threading with sealing surfaces, eliminating the need for manual screwing operations while maintaining connection reliability
Solution Approach 2:
The patent introduces a sealing element as an intermediary component between the valve body and holder. This sealing element mediates the connection by providing a dedicated sealing surface that interacts with the threading during the quarter-turn engagement, ensuring reliable sealing without requiring excessive tightening force that could damage components
2Strength
If manual screwing is required for canister replacement, then the connection strength is improved, but the time consumption increases
Solution Approach 1:
The patent incorporates pre-configured threading and sealing surfaces on both the valve body and holder that are designed to automatically align and engage during insertion. The threading geometry and sealing surface orientation are predetermined to achieve optimal connection strength through a single quarter-turn motion, eliminating the time-consuming trial-and-error adjustment associated with manual screwing
Solution Approach 2:
The patent employs a dynamic coupling mechanism where the threading and sealing surfaces work together during the quarter-turn engagement process. The interaction between the external threading on the valve body and internal threading in the holder creates a progressive engagement that simultaneously builds connection strength and establishes sealing, completing the connection in one rapid motion rather than multiple static tightening steps

Function Achieved in This Case
Facilitates quick and simple replacement of gas canisters by unskilled users, reduces the risk of overtightening or seal damage, and ensures reliable gas flow for carbonation processes.
Implementation Method 1
the socket including a seal with at least one lateral opening to enable fluidic flow between one or more laterally oriented ports of a valve of the canister into the socket
Implementation Method 2
a holding mechanism configured to hold a lateral projection from the canister after insertion of the valve into the socket such that the valve remains in the socket

AI summary
A carbonation machine may include a carbonation head, a holder that is configured to hold a gas canister, the holder comprising a connector with a socket configured to enable linear insertion of a valve of the canister into the socket, the socket including a seal with at least one lateral opening to enable fluidic flow between one or more laterally oriented ports of the valve and a conduit of the holder while preventing leakage of gas from the fluidic flow, and a holding mechanism configured to hold a lateral projection from the canister after insertion of the valve into the socket such that the valve remains in the socket, and an activation mechanism configured to operate the valve to release the gas from the canister when inserted into the socket so as to enable the gas to flow via the conduit to the carbonation head.
