Solution Overview

Problem

Modern coffee-producing machines with frothing devices for milk are often complex and cumbersome, making them difficult to store in refrigerators due to their size and design.

Innovation Solution

A movable frothing device integrated into a beverage jug that can be slid between retracted and extended positions, allowing for a compact footprint when stored and easy connection to coffee makers, with a steam inlet and frothed beverage outlet positioned for ergonomic use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the frothing device is made fixed and integrated into the jug, then the structure is simpler, but the footprint of the jug increases making refrigerator storage difficult

Engineering Contradiction:
Improvestructure simplicityVSAvoidjug footprint
Core Design Contradiction:
Device complexityVSArea of stationary object

Solution Approach 1:

The frothing device is made movable rather than fixed, allowing it to slide between a retracted position (reducing footprint for storage) and an extended position (enabling functionality during use). This dynamic configuration resolves the contradiction between structural simplicity and compact storage.

Inventive Principle:
Principle #15Dynamics

2Area of stationary object

If the frothing device is made movable to reduce footprint, then refrigerator storage becomes easier, but the device complexity increases

Engineering Contradiction:
Improvejug footprintVSAvoiddevice complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The frothing device is separated from the main jug body as an independent movable component that can slide in and out. This segmentation allows the jug to maintain a compact form for storage while enabling the frothing function to be added only when needed, minimizing the impact on overall device complexity.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If prior art jugs and frother devices are used, then frothing functionality is achieved, but the devices are complex and cumbersome

Engineering Contradiction:
Improvefrothing functionalityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The frothing device is merged with the jug as an integrated movable component rather than a separate device. This combination eliminates the need for separate frother devices and simplifies the overall system while maintaining full frothing functionality through the sliding mechanism.

Inventive Principle:
Principle #5Merging (Combining)

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 simplifies the manufacturing and use of the jug, reduces its footprint for easier storage, and provides a space-saving design while maintaining functionality for frothing and heating beverages, enhancing user experience and efficiency.

Implementation Method 1

Hot, pressurized steam is delivered through the frothing device in order to suck milk from the jug, heat and optionally froth the milk with air

Methodology Applied
Scientific EffectSteam heating: Heating

Implementation Method 2

The movable frothing device slides with a translation movement in a seat provided on the jug

Methodology Applied
Scientific EffectFriction: Friction
