Solution Overview

Problem

Existing single-portion packages for preparing aromatic beverages face challenges in effectively distributing fluid flow and confining/compressing edible substances, particularly with non-compacted granular substances, which affects beverage extraction efficacy and requires adjustments for different types of products.

Innovation Solution

A single-portion package with a disc-like flow distribution element that moves between initial and second positions within the package, providing confinement in the dry state and compression upon fluid injection, utilizing pressure-fit and retaining elements to manage fluid flow and substance compression.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a flow distribution element is arranged at a certain position within the internal volume to confine the edible substance, then the substance confinement is improved, but the beverage extraction efficacy deteriorates due to compression in dry state

Engineering Contradiction:
Improvesubstance confinementVSAvoidbeverage extraction efficacy
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The flow distribution element is designed to be movable rather than fixed, allowing it to transition between different positions. In the dry state, it confines the substance without compression. During beverage preparation, it moves to compress the substance, thereby resolving the contradiction between maintaining substance stability and ensuring extraction efficacy.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the position parameter of the flow distribution element based on the state (dry vs. wet). This parameter change allows the element to provide confinement when needed and compression when needed, optimizing both substance stability and beverage extraction efficacy under different conditions.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If a flow distribution element is arranged to compress the edible substance, then the beverage extraction efficacy is improved, but the substance confinement deteriorates due to premature compression

Engineering Contradiction:
Improvebeverage extraction efficacyVSAvoidsubstance confinement
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The flow distribution element transitions from a static confinement position to a dynamic compression position only when activated by pressurized fluid flow. This ensures substance confinement is maintained during storage and transport, while compression is applied only at the moment of beverage preparation for optimal extraction.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The flow distribution element is pre-positioned to confine the substance without compression during storage. The compression action is prepared but not executed until the moment of beverage preparation when pressurized fluid flow activates it, ensuring confinement is maintained until the preliminary action of compression is precisely timed.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If the flow distribution element is fixed in position, then the device complexity is reduced, but the adaptability to different edible substances and liquid products deteriorates

Engineering Contradiction:
Improveflow distribution element positioningVSAvoidproduct adaptation
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The flow distribution element is designed with movable capability allowing it to adapt to different substances and products by changing its position. This dynamic feature provides versatility for different edible substances and liquid products while maintaining relatively simple device structure through a single movable element rather than multiple fixed configurations.

Inventive Principle:
Principle #15Dynamics

AI summary

The present invention discloses a single-portion package (1) presenting a flow distribution element (4) provided so as to divide the internal volume into a first free space (1.1) and a second compartment (1.2) containing at least one substance, and whereby said flow distribution element (4) is displaced along successive positions along and relative to the sidewall (3.1) under the fluid pressure developing on said first space (1.1), and so that it initially confines said substance and it then confines and/or compresses said substance. The present invention further relates to a system (10) for preparing liquid products and comprising at least two of said single-portion packages (1, 1') preferentially presenting different flow distribution elements (4, 4') so that it results for example in different first spaces (1.1, 1.1') and respective compartments (1.2, 1.2').
