Solution Overview

Problem

Existing capsule technologies for extracting aromatic substances face challenges in controlling flow conditions at entry and exit, leading to inefficient extraction and increased production costs due to the need for external materials for airtightness and complex construction materials.

Innovation Solution

A capsule design featuring controlled opening elements with removable fixtures that allow for precise configuration and dimensioning of flow passageways at entry and exit, eliminating the need for external materials and ensuring airtightness without material rupture, using friction unions or positive locking mechanisms to control the flow pattern and distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If material rupture is used for flow entry and exit, then flow passageway is created, but control over flow conditions and distribution is poor

Engineering Contradiction:
Improvecontrol over flow conditionsVSAvoidcapsule construction
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The capsule employs dynamic opening elements that can transition between closed and open states, allowing controlled flow passageways to be created on demand rather than relying on static material rupture. This enables precise control over flow conditions while maintaining a simpler capsule structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The capsule is divided into separate functional components including opening elements, element fixtures, and flow distribution elements. This segmentation allows independent optimization of each component for controlling flow conditions without complicating the overall capsule construction.

Inventive Principle:
Principle #1Segmentation

2Reliability

If external materials are used for airtightness, then capsule sealing is ensured, but production costs increase and recycling is simplified

Engineering Contradiction:
ImproveairtightnessVSAvoidproduction costs
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention removes the need for external sealing materials by integrating airtightness functionality into the capsule's own construction elements. The opening elements and fixtures work together to provide sealing without requiring additional external materials, thereby reducing production costs while maintaining reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If flow passageway section is maximized at entry, then extraction efficacy is improved, but control over flow distribution becomes difficult

Engineering Contradiction:
Improveextraction efficacyVSAvoidflow distribution control
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The capsule incorporates flow distribution elements with locally optimized characteristics, including varying aperture sizes and orientations at different positions. This allows the overall flow passageway section to be maximized for high extraction efficacy while maintaining precise control over flow distribution patterns through localized adjustments.

Inventive Principle:
Principle #3Local quality

4Duration of action of moving object

If internal perforation means are used, then flow retention is achieved, but external elements are needed for airtightness

Engineering Contradiction:
Improveflow retention timeVSAvoidcapsule construction
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The invention combines the flow retention function with the existing opening elements and fixtures, eliminating the need for separate internal perforation means and external airtightness materials. The integrated design achieves flow retention while maintaining capsule simplicity and avoiding additional construction complexity.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The present invention refers to a capsule containing at least one aromatic substance for producing a beverage by means of its crossing by a pressurized fluid flow, and comprising at least one controlled opening element retained in a removable manner at least in one zone of the capsule facing the flow upstream and/or downstream. Said controlled opening element, by means of applying at least one certain actuation force exerted by a respective extraction device, may be displaced in at least linear or rotating fashion from an initial retaining position, that produces the airtight closure of the capsule, to at least one following position, thereby releasing at least one section of flow passageway of previously defined configuration and dimension in view of an optimized flow distribution inside said capsule.
