Solution Overview

Problem

Existing coffee machines face challenges in flexibility and handling, particularly in simultaneously filling two separate cups with coffee and milk froth, due to the fixed arrangement of outlets and limited installation space, which complicates the preparation of beverages like cappuccinos.

Innovation Solution

The implementation of a channel fork with two sub-channels connecting a single milk/milk froth supply channel to two coffee feed channels, allowing even distribution of fluid flow and enabling the filling of one or two separate beverage containers simultaneously, while being removable for easy cleaning and made of dishwasher-safe plastic.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single milk froth nozzle is arranged next to or on the coffee outlet, then the structure is compact and installation space is saved, but only one cup can be filled with coffee and milk froth at the same time

Engineering Contradiction:
Improvecapability to fill multiple cups simultaneouslyVSAvoidnumber of milk froth supply channels
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The single milk froth supply channel is segmented into two separate outlet paths through the channel fork, allowing the fluid to be distributed to two different cups simultaneously. This segmentation enables one supply channel to serve multiple outlets, resolving the contradiction between compact structure and multi-cup filling capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The channel fork acts as a universal component that distributes milk froth to multiple outlets. This multi-functional element allows a single supply channel to fulfill the role of multiple supply channels, enabling simultaneous filling of multiple cups without increasing the number of supply channels.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If two separate milk froth supply channels are provided to fill two cups simultaneously, then the capability to fill multiple cups is improved, but the installation space requirements increase and the structure becomes more complex

Engineering Contradiction:
Improvecapability to fill multiple cups simultaneouslyVSAvoidinstallation space in outlet area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

Two separate milk froth supply channels are merged into a single supply channel that feeds both outlets through the channel fork. This merging reduces the installation space required while maintaining the capability to fill multiple cups simultaneously, as the single supply channel serves both outlets through the fork structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The channel fork introduces a spatial dimension solution by distributing the fluid flow in a fork-like configuration. This dimensional arrangement allows the single supply channel to reach two outlets without requiring two separate linear supply paths, thereby saving installation space while enabling multi-cup filling.

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

3Area of stationary object

If the outlets are arranged close together to save space, then installation space is optimized, but it becomes problematic to fill two separate cups simultaneously

Engineering Contradiction:
Improveoutlet area spaceVSAvoidcapability to fill two cups simultaneously
Core Design Contradiction:
Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The channel fork acts as an intermediary component between the single milk froth supply channel and the two outlets. It mediates the fluid distribution, allowing the outlets to remain close together for space optimization while still enabling simultaneous filling of two cups through the fork's distribution capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If the outlets are arranged far apart to allow simultaneous filling of two cups, then the capability to fill multiple cups is improved, but the distance is larger than the diameter of a conventional coffee cup making single cup filling difficult

Engineering Contradiction:
Improvecapability to fill two cups simultaneouslyVSAvoidconvenience of filling single cup
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system provides dynamic flexibility by allowing the user to choose between filling one cup or two cups simultaneously. The channel fork enables the outlets to be positioned at an optimal distance that accommodates both scenarios, making the system adaptable to different operational needs without compromising ease of operation for either single or dual cup filling.

Inventive Principle:
Principle #15Dynamics

AI summary

The coffee maker has two channel outlets (3, 3') arranged at a distance each other, where the distance between the channel outlets is selected so that a common filling of two beverage containers or a single beverage container is alternatively possible. Two coffee supply channels (1, 1') are attached to one of the channel outlets. A channel fork (4) is provided with two partial channels (5, 5'), which connect a milk- and/or milk foam supply channel (2) with the channel outlets in communicating manner.
