Beverage Machine Power Switch Operated by Functional Part Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beverage preparation machines often require manual operation of the power switch, which can lead to incorrect configurations and increased user effort, potentially resulting in inappropriate machine operation during beverage preparation or dispensing.
Innovation Solution
A beverage preparation machine with a functional part that can automatically operate the main switch when moved between configurations for preparing and dispensing beverages, eliminating the need for separate power switch operation and preventing inappropriate machine operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power switch is operated manually, then the user can control power supply, but the user effort increases and incorrect operation may occur
Solution Approach 1:
The functional part automatically operates the main power switch based on its own position changes between beverage preparation and dispensing configurations, eliminating the need for separate manual power switch operation. The system serves itself by using the position of the functional part to control power supply to activatable units.
Solution Approach 2:
The power supply is automatically activated before beverage preparation begins when the functional part is in the preparation configuration, and deactivated after dispensing when in the different configuration. This preliminary automatic action prevents incorrect operation and reduces user effort.
2Reliability
If the power switch is operated manually, then the user has control, but incorrect machine operation may occur during beverage preparation or dispensing
Solution Approach 1:
The system uses the position of the functional part as feedback to automatically control power supply. When the functional part is in the beverage preparation configuration, power is supplied to activatable units; when in the dispensing configuration, power is deactivated. This automatic feedback mechanism prevents incorrect operation.
Solution Approach 2:
The functional part itself controls the power supply state based on its position, eliminating reliance on manual user input that could lead to incorrect operation. The system self-regulates power supply according to operational needs.

AI summary
A machine (1) for preparing and dispensing a beverage includes a beverage preparation and dispensing unit that has: an ingredient container (46, 50, 50a); a dispensing head (35) with a beverage outlet (36) for dispensing the beverage to a beverage dispensing surface (5, 37); and a liquid circuit for processing the beverage and delivering such beverage into the beverage outlet (36). The liquid circuit has at least one activatable unit (40, 51, 52) that is passed through by liquid during beverage preparation. The machine further includes: a power unit (54′) connected to a main switch (54) and to the activatable unit(s) (40, 51, 52); and a functional part that is configured to perform a function other than actuating the main switch (54) and that has a beverage preparing and dispensing position and that is movable into a different position in which no beverage is intended to be prepared or dispensed. The functional part (40, 35) is further configured to operate, when moved to the dispensing position or to the different position, the main switch (54) so as to enable or disable the supply of power from the power unit (54′) to the activatable unit(s) (40, 51, 52).
