Solution Overview

Problem

Existing beverage preparation machines often result in beverages with inconsistent foam and risk of soiling and malfunction due to direct jets of beverage entering internal machine parts, disrupting the flow and foam formation.

Innovation Solution

A collector module with a fluid receiving plate, deflector wall, and outlet conduit design that guides the beverage flow gradually, preventing direct jets from entering the outlet conduit and ensuring a consistent flow and reduced risk of soiling, featuring a deflector wall positioned perpendicular to the fluid receiving plate and an outlet conduit with slanted gutter segments to manage the flow effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a direct fluid path is provided from the fluid receiving plate to the outlet conduit, then beverage extraction efficiency is improved, but beverage consistency and foam quality deteriorate due to direct jet impingement

Engineering Contradiction:
Improvebeverage extraction efficiencyVSAvoidbeverage consistency and foam quality
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The patent introduces an intermediary structure (the curved surface and deflector wall) between the fluid receiving plate and the outlet conduit. This intermediary redirects the beverage flow from a direct jet path to a gradual flow path along the curved surface, preventing direct impingement while maintaining efficient extraction. The intermediary element transforms the harmful direct jet into a beneficial controlled flow that preserves foam quality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If openings are provided in the fluid receiving plate for beverage reception, then beverage flow rate is improved, but soiling and malfunction risk increases due to direct jets entering machine parts

Engineering Contradiction:
Improvebeverage flow rateVSAvoidsoiling and malfunction risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful direct jet of beverage into a beneficial controlled flow by utilizing the curved surface and deflector wall. The same high-velocity flow that causes soiling is redirected to travel along the curved surface and exit gradually through the outlet conduit. The harmful kinetic energy is transformed into a controlled flow pattern that prevents soiling while maintaining extraction efficiency.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Stability of the object's composition

If a deflector wall is added to prevent direct jet impingement, then beverage consistency and foam quality are improved, but device complexity increases

Engineering Contradiction:
Improvebeverage consistency and foam qualityVSAvoidstructure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent merges multiple functions into the outlet conduit structure itself. The curved surface, deflector wall, and outlet conduit are integrated into a single continuous structure rather than separate components. This merging reduces assembly complexity while maintaining the flow control functionality. The outlet conduit simultaneously serves as the beverage exit path and the flow redirection mechanism.

Inventive Principle:
Principle #5Merging (Combining)

4Volume of moving object

If the outlet conduit is positioned directly below the fluid receiving plate, then device compactness is improved, but beverage flow control deteriorates due to direct jet entry

Engineering Contradiction:
Improvedevice compactnessVSAvoidbeverage flow control
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The patent introduces a dimensional change in the flow path by utilizing the curved surface that extends in a direction away from the fluid receiving plate. Instead of a direct vertical path, the beverage flow is redirected along a curved trajectory in three-dimensional space. This dimensional change allows the outlet conduit to be positioned compactly while maintaining excellent flow control through the curved path geometry.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

Dispensing module for a beverage preparation machine For providing a beverage with a proper consistency using a capsule- based brewing system wherein hot liquid is injected into the capsule under pressure, which capsule is placed against a brewing plate (210) with protrusion (212) arranged to cut the capsule cover under pressure, it has been found that a free flow of the prepared beverage can flow gradually from the brewing plate (210) towards an outlet nozzle (126). An open passage (206) from the brewing plate (210) via a collector chamber (204) downstream of the brewing plate, to the outlet nozzle (126) may be provided with an open and slanted gutter (222) to lead the beverage out of the collector chamber (204) to provide the best results. Due to the open nature of the conduit, jets of beverage form the brewing plate may the open gutter and soil the machine. This may be prevented by providing appropriate shielding (250) between the brewing plate and the gutter or an opening thereof.
