Milk Frothing Assembly Interlock for Covered Steam Dispenser Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art apparatuses for making beverages with milk frothing devices pose a risk of accidental steam exposure to users during removal of the milk container, as the steam dispenser can be left uncovered.
Innovation Solution
The apparatus features a locking mechanism that prevents simultaneous removal of the milk frothing device and container, allowing the frothing device to remain in position until the container is removed, ensuring the steam dispenser is covered and reducing the risk of steam exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the milk container and milk frothing device are removed simultaneously as a single body, then the operation is simple and quick, but the user may be accidentally struck by steam from the uncovered steam dispenser
Solution Approach 1:
The removal operation is segmented into two independent steps: first removing the milk container, then removing the milk frothing device. This is achieved through a locking mechanism that prevents the frothing device from being removed when the container is present, thereby eliminating the steam exposure risk while maintaining operational simplicity through clear sequential guidance
Solution Approach 2:
The locking mechanism performs a preliminary action by automatically preventing the removal of the milk frothing device when the milk container is still in place. This preliminary lock ensures that the steam dispenser remains covered during container removal, eliminating the harmful steam exposure before it can occur
2Object-affected harmful factors
If the milk container and milk frothing device are removed separately, then user safety is improved, but the operation becomes more complex and time-consuming
Solution Approach 1:
The locking mechanism operates automatically based on the presence or absence of the milk container, eliminating the need for user intervention to control the sequencing. The system self-regulates the removal process by mechanically preventing premature removal of the frothing device, thereby reducing operational complexity while ensuring safety
Solution Approach 2:
The locking mechanism is integrated into the existing structure of the milk frothing device and steam dispenser assembly, combining the safety function with the existing components. This integration avoids adding separate complex control systems, maintaining simplicity while achieving the required safety functionality

AI summary
This disclosure relates to an apparatus (1) for making a beverage, in particular a beverage containing milk. The apparatus (1) comprises a machine body, a milk container (2) and a milk frothing device (3) for mixing milk with air and steam. The milk frothing device (3) is removably mountable in a seat (10) in an outer wall (11) of the machine body. The milk container (2) is removably couplable to the milk frothing device (3). The apparatus (1) also comprises a locking member (5) for locking the milk frothing device (3) in the mounted condition. The milk container (2) interacts with the locking member (5) in such a way that, when the milk container (2) is coupled to the milk frothing device (3) in the mounted condition, the locking member (5) is active and prevents removal of the milk frothing device (3) from the seat (10), and in such a way that, when the milk container (2) is uncoupled from the milk frothing device (3), the locking member (5) may adopt the inactive condition for allowing removal of the milk frothing device (3) from the seat (10). Therefore, the milk frothing device (3) and the milk container (2) in the coupled condition are not simultaneously removable from the machine body.
