Machine for preparing beverages comprising an opening disposition and process for preparing a beverage with anticipated opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage preparation machines require complex and unreliable methods to open single dose packages, often necessitating perforation inside the extraction device, which complicates the process and may affect the aromatic properties of the beverage.
Innovation Solution
A machine that anticipates opening single dose packages by creating passageways before they are supplied to the extraction device, using a rotating actuation device with protrusions to interact with the package walls, reducing complexity and improving reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If perforation means are provided inside the extraction device to open single dose packages, then the packages can be opened for beverage extraction, but the device complexity increases and operation reliability decreases
Solution Approach 1:
The opening disposition creates passageways in the single dose packages in advance, before the packages are supplied to the extraction device. This preliminary action eliminates the need for complex perforation mechanisms inside the extraction device, thereby reducing device complexity while maintaining operational reliability.
Solution Approach 2:
The opening function is extracted from the extraction device and placed in a separate opening disposition located upstream. This separation removes the disturbing element (perforation mechanism) from the extraction device, simplifying its structure and improving reliability by dedicating specific functions to specific components.
2Ease of manufacture
If single dose packages are opened immediately before water injection, then aromatic properties are preserved, but the process complexity increases
Solution Approach 1:
Passageways are created in the packages in advance during the opening disposition stage, allowing the packages to be opened earlier in the process. This enables better conservation of aromatic properties by avoiding repeated handling and exposure, while simultaneously simplifying the overall process by separating opening from extraction operations.
3Reliability
If a rotating actuation device with protrusions is used to create passageways, then opening reliability improves, but the device structure becomes more complex
Solution Approach 1:
The opening disposition is integrated with the actuation device that supplies packages to the extraction device. The rotating actuation device with protrusions combines the functions of package advancement and passageway creation in a single mechanism, improving opening reliability while minimizing the addition of separate complex components.
