Solution Overview

Problem

Beverage making systems face challenges with cross-contamination between different beverages and maintaining hygiene due to residue buildup, particularly in systems where beverages directly contact machine parts.

Innovation Solution

A beverage making apparatus with interchangeable beverage outlets and a capsule receiving station that minimizes cross-contamination by using movable outlet tubes to direct the beverage flow, allowing for different outlet configurations for various beverages and automatic selection based on the beverage type.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single beverage outlet is used for multiple beverage types, then the device complexity is reduced, but cross-contamination between different beverages occurs

Engineering Contradiction:

Improvenumber of outletsVSAvoidcross-contamination

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent implements a movable outlet tube that can be dynamically repositioned between different beverage outlets based on the type of beverage being prepared. The outlet tube moves from a first position for a first beverage type to a second position for a second beverage type, allowing a single outlet structure to serve multiple functions without cross-contamination.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The beverage dispensing system is segmented into multiple separate beverage outlets, each dedicated to a specific beverage type. Instead of one outlet serving all beverages, the system divides the outlet function into distinct segments (outlet 1, outlet 2, etc.), preventing cross-contamination while maintaining manageable device complexity.

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If multiple beverage outlets are provided for different beverages, then cross-contamination is reduced, but the device complexity increases

Engineering Contradiction:

Improvecross-contaminationVSAvoidnumber of outlets

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The outlet tube is designed as a universal component that can serve multiple beverage outlets. Rather than having fixed outlets for each beverage type, the single outlet tube can be positioned at different locations to dispense different beverages, making the system multi-functional while avoiding the complexity of multiple permanent outlets.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses a dynamic outlet tube that can be repositioned to different beverage outlets based on the selected beverage type. This dynamic capability allows the system to provide multiple dedicated outlets when needed while maintaining a simpler overall structure compared to having all outlets permanently installed and active.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If beverage residues remain on machine parts between operations, then the ease of operation is maintained, but hygiene conditions deteriorate

Engineering Contradiction:

Improvecontinuous operationVSAvoidhygiene contamination

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The outlet tube is extracted as a separate, removable component from the beverage making apparatus. This allows the outlet tube to be easily removed and cleaned between beverage preparations, or replaced with a fresh outlet tube for each beverage type, thereby maintaining hygiene conditions while allowing continuous operation of the main apparatus.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system allows for the use of disposable outlet tubes that are discarded after a single use or after a specific beverage type. This eliminates the need for thorough cleaning between different beverage types, maintaining hygiene standards while enabling continuous operation without complex cleaning mechanisms.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution effectively reduces cross-contamination and maintains hygiene by using interchangeable outlets tailored to specific beverages, ensuring optimal preparation and cleanliness.

Implementation Method 1

The apparatus then injects water into the capsule, where it dissolves or is infused by the beverage making ingredient to form the beverage

Methodology Applied

Scientific EffectDissolution: Solvation

Implementation Method 2

The beverage flows out of the capsule through a suitable outlet, which may be simply an opening or perforation in the capsule, or it may comprise an outlet tube that pierces an outlet region of the capsule

Methodology Applied

Scientific EffectGravity: Gravitation
