Centrifugal Beverage Capsule With Outer Cavity Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage preparation methods using centrifugal forces result in beverage contamination and complex device designs due to direct contact between the beverage and the device during collection, affecting taste and requiring frequent rinsing.
Innovation Solution
A capsule design with an outer and inner wall, featuring beverage outlets formed by centrifugal pressure on the inner wall, allowing liquid to flow from the inner to the outer cavity, and a bottom outlet for efficient drainage, maintaining overpressure to prevent contact with the device and simplify the design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If beverage is collected by a collecting assembly of the device, then beverage collection is achieved, but beverage contamination occurs and device complexity increases
Solution Approach 1:
The beverage collection function is extracted from the device and transferred to the capsule itself. The capsule's outer wall forms a collecting cavity that receives beverage directly from the inner cavity, eliminating the need for a separate device collecting assembly. This resolves the contradiction by simplifying the device while maintaining beverage collection capability.
Solution Approach 2:
The capsule serves as a disposable container that performs both brewing and collection functions. By making the capsule the collection vessel rather than using a reusable device component, the system avoids contamination of permanent device parts and eliminates the need for complex cleaning mechanisms, thereby reducing device complexity.
2Ease of operation
If beverage contacts the device during collection, then beverage collection is achieved, but beverage contamination and taste cross-contamination occur
Solution Approach 1:
The beverage collection process is extracted from the device environment and contained within the capsule's outer cavity. The beverage never contacts the device, eliminating contamination and taste cross-contamination risks while maintaining effective collection functionality.
Solution Approach 2:
The capsule's outer wall acts as an intermediary container between the beverage and the device. This intermediate structure allows beverage collection without direct contact with device surfaces, preventing contamination and taste transfer.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents contamination and simplifies the device design by allowing efficient drainage of the beverage without direct contact, maintaining beverage quality and reducing the need for frequent rinsing.
Implementation Method 1
rotating the container around its central axis to force liquid through beverage outlets from the inner cavity to the outer cavity under the effect of centrifugal pressure
Implementation Method 2
maintaining an overpressure of supplied liquid in the container to enable the beverage to be drained from the outer cavity out of the container
