Solution Overview
Problem
Existing capsule systems for beverage preparation in centrifugal brewing devices require specific perforating means, limiting adaptability to different beverage types and brewing devices, and can become less effective over time due to blunt perforating means.
Innovation Solution
A capsule design with a deformable perforating wall and closing wall that can be perforated by mechanical pressure or internal fluid pressure, allowing for adjustable outlet creation and improved liquid distribution during centrifugation, enabling use in various brewing devices without specific perforating means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a capsule uses a closure wall that is removed or perforated for enabling insertion of liquid injection means and beverage extracting means, then the capsule can be used in a specific brewing device with perforating means, but the size and location of the openings are dependent essentially on the configuration of the perforating means, making it impossible to vary the openings to adapt to different beverage types
Solution Approach 1:
The capsule employs a deformable closing wall that can be dynamically perforated during the brewing process. The wall transitions from a sealed state to a perforated state through mechanical deformation by the brewing device, allowing the opening configuration to be determined by the brewing device's action rather than being fixed during manufacturing. This enables the same capsule design to adapt to different brewing devices and beverage types.
Solution Approach 2:
The capsule is pre-designed with a closing wall that is configured to be perforated by the brewing device's perforating means. The wall's initial sealed state preserves the beverage ingredients until use, and the pre-configured deformability allows for controlled opening when the brewing device applies mechanical action. This preliminary preparation enables both freshness preservation and adaptability.
2Reliability
If a capsule uses a closure wall that is removed or perforated for enabling insertion of liquid injection means, then the capsule can be opened for beverage extraction, but the perforating means may become blunt over time thus rendering the opening less effective or requiring more force
Solution Approach 1:
The capsule's closing wall is designed with controlled deformability that anticipates the perforating action. The wall material and structure are pre-configured to facilitate clean perforation through controlled deformation, reducing the force required and preventing the perforating means from becoming blunt. This beforehand preparation of the wall's mechanical properties protects the brewing device's perforating means from wear over time.
3Adaptability or versatility
If a capsule uses a deformable closing wall that can be perforated by mechanical pressure, then the capsule can be opened without specific perforating means in the brewing device, but the closing wall must be configured to deform under external mechanical pressure
Solution Approach 1:
The closing wall is constructed from materials or composite structures with specific mechanical parameters that allow controlled deformation. The wall's strength, flexibility, and deformability are carefully selected to balance two requirements: maintaining structural integrity to preserve beverage freshness during storage and transport, while enabling easy perforation when external mechanical pressure is applied during brewing. This parameter optimization allows the same wall design to work with various brewing devices without requiring specific perforating means.

Implementation Method 1
rotating the capsule along a central axis (I) to produce centrifugal forces on the liquid traversing the capsule thereby forcing the beverage out of the capsule by such centrifugal forces
Implementation Method 2
The capsule may be configured to be deformed by the external mechanical pressure in order to provide the perforation of one or more beverage outlets in the closing wall
Implementation Method 3
The capsule may also be configured to be deformed for such perforation by the fluid and/or liquid internal pressure building up in the capsule
