Milk Frothing Nozzle Locking Mechanism Against Steam Jet Risk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing milk-based drink production devices with steam output nozzle tips from coffee makers pose safety risks due to the potential projection of steam and drink jets when the frothing system is not properly attached or removed during operation.
Innovation Solution
A milk-based drink production device with a connection system that includes extraction and connection safety mechanisms, such as a bolt and stop system, which prevent the frothing system from being removed or connected improperly, ensuring a secure attachment and preventing steam jets from being directed at the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connection system allows the frothing system to be removed during operation, then the device is easier to clean and maintain, but steam jets may be projected forward injuring the user
Solution Approach 1:
The connection safety mechanism applies preliminary anti-action by preventing the connection system from moving to the connected position when the frothing system is not installed. The safety mechanism detects the absence of the frothing system and blocks the connection action in advance, preventing the harmful steam jet projection before it can occur.
2Object-affected harmful factors
If the connection system prevents improper connection, then user safety is improved, but the device complexity increases
Solution Approach 1:
The connection and extraction safety mechanisms are merged with the existing connection system components. The safety functions are integrated into the mobile jaw, lever, and transfer piece mechanisms that already exist in the connection system, rather than adding completely separate safety systems. This reduces overall complexity while maintaining safety functionality.
Solution Approach 2:
The safety mechanisms operate automatically based on the physical state of the frothing system installation. The system self-detects whether the frothing system is properly installed through the mechanical interaction of components like the bolt and cavity, and self-regulates the connection state without requiring external monitoring or control systems.
3Adaptability or versatility
If the frothing system can be freely moved between installed and removed positions, then the device is more versatile and easier to operate, but safety risks increase due to potential steam jet projection
Solution Approach 1:
The system dynamically adjusts the allowed positions of the frothing system based on the connection state. When the connection system is in the disconnected position, the frothing system can be freely moved between installed and removed positions. When the connection system moves to the connected position, the extraction safety mechanism automatically constrains the frothing system to remain in the installed position, providing dynamic safety control.

AI summary
Provided is a milk-based drink production device with a connection system designed to work with a steam output nozzle tip of a coffee maker, where said connection system has a connected position, in which a watertight connection is formed between the steam output nozzle tip and the device, and a disconnected position, in which the device may be separated from the steam output nozzle tip, and the device contains a frothing system which shifts between an installed position on the device and a position removed from the device. The device contains extraction safety mechanisms which prevent the frothing system from moving from the installed position to the removed position when the connection system is in the connected position and/or connection safety mechanisms which prevent the connection system from moving from the disconnected position to the connected position when the frothing system is not in the installed position.
