Solution Overview

Problem

Current beverage preparation systems are inefficient and cumbersome due to the need for frequent insertion and disposal of single-serving capsules for milk powder, leading to time delays and the risk of using unsuitable milk powder for froth production, resulting in suboptimal milk foam consistency.

Innovation Solution

A multi-portion container designed for airtight and aroma-tight storage of milk powder, equipped with a docking system for use in beverage preparation devices, allowing simultaneous or separate preparation of coffee and milk froth, ensuring only foamable milk powder is used and reducing the need for frequent capsule changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If single-serving milk powder capsules are used for each cappuccino preparation, then milk foam consistency is ensured, but frequent insertion and disposal of capsules causes time delays and operational inefficiency

Engineering Contradiction:
Improvemilk foam consistencyVSAvoidtime delays from frequent capsule changes
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The milk powder container is divided into multiple sealed portions, with each portion containing a single serving of milk powder. This segmentation allows the container to hold multiple servings while maintaining the quality and consistency of each individual portion, resolving the contradiction between ensuring consistent milk foam and avoiding frequent container changes.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a refillable storage container for milk powder is used, then frequent capsule insertion is avoided, but unsuitable milk powder may be stored leading to poor milk foam production

Engineering Contradiction:
Improvereduced capsule insertion frequencyVSAvoidmilk foam quality
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The milk powder is pre-portioned and pre-sealed in individual compartments within the container before use. This preliminary action ensures that only suitable, foamable milk powder is available for each serving, while allowing the container to be refilled once with multiple portions, thus improving ease of operation without compromising milk foam quality.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If multiple capsule types (coffee, cocoa, milk powder) share one receiving chamber, then device complexity is reduced, but preparation of coffee-milk beverages requires sequential operations increasing time delays

Engineering Contradiction:
Improvenumber of receiving chambersVSAvoidsequential preparation time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The multi-portion container serves multiple functions: it stores different types of powdered beverage constituents (milk powder, cocoa, coffee), provides airtight sealing for each portion, and interfaces with the beverage preparation device through a universal docking mechanism. This multi-functionality allows the single receiving chamber to handle various beverage types without requiring sequential operations, as the container can be pre-loaded with different portions for simultaneous or sequential beverage preparation.

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