Solution Overview

Problem

Existing disposable assemblies for liquid food products, such as milk, require significant energy for cooling and heating, are costly due to mechanical robustness for steam generation, and result in a 'cooked milk taste, necessitating frequent and costly cleaning to maintain hygiene.

Innovation Solution

A disposable assembly using a concentrated liquid food product with an eductor and microfiltration device that allows for efficient mixing with water to create a foamed product at ambient temperatures, reducing energy consumption and maintaining hygiene through a hydrophobic microfiltration device, eliminating the need for steam and cooling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cooling means are used to cool the milk in the disposable assembly, then the milk can be preserved during transport and storage, but the energy consumption increases significantly

Engineering Contradiction:
Improvemilk preservationVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent changes the physical state of milk from liquid to concentrated form by removing water. This parameter change (concentration) fundamentally alters the product's properties, allowing it to be stored and transported at ambient temperature without cooling, thus eliminating the energy consumption associated with refrigeration while maintaining preservation and hygiene

Inventive Principle:
Principle #35Parameter changes

2Temperature

If a steam generator is used to heat the milk for hot foamed products, then hot foamed products can be produced, but the mechanical construction must be robust to resist high pressures, increasing cost

Engineering Contradiction:
Improvehot foamed product temperatureVSAvoidmechanical robustness
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical steam generation system with a heating element that directly heats the concentrated milk. This substitution eliminates the need for high-pressure steam generation and the associated robust mechanical construction, reducing device complexity and cost while still achieving the desired temperature for hot foamed products

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the physical state of milk from liquid to concentrated form, which allows for direct heating without requiring high-pressure steam generation. This parameter change enables temperature control through simpler heating mechanisms, eliminating the need for mechanically robust steam generation systems

Inventive Principle:
Principle #35Parameter changes

3Reliability

If frequent cleaning is performed to maintain hygiene, then hygiene standards are maintained, but the downtime of the operating apparatus increases and energy consumption increases

Engineering Contradiction:
Improvehygiene standardVSAvoiddowntime
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent changes the physical state of milk to concentrated form, which fundamentally reduces the risk of bacterial growth and spoilage. This parameter change maintains high hygiene standards throughout storage and operation, eliminating the need for frequent cleaning cycles and reducing both downtime and energy consumption associated with cleaning

Inventive Principle:
Principle #35Parameter changes

4Duration of action of stationary object

If concentrated liquid food product is used instead of liquid milk, then the product can be stored at ambient temperature without degradation, but additional mixing with water is required

Engineering Contradiction:
Improvestorage durationVSAvoidmixing requirement
Core Design Contradiction:
Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The patent uses the eductor device to automatically mix water with the concentrated milk through fluid dynamics principles. This substitution of manual or complex mixing systems with a passive eductor device based on pressure differential simplifies the overall system while enabling the necessary reconstitution of milk from concentrated form

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
