Solution Overview

Problem

Existing methods for freezing and thawing milk, particularly colostrum, expose the milk to air and germs, leading to contamination, and require multiple handling steps that increase the risk of germ introduction and nutrient loss.

Innovation Solution

A device with a temperature control element that remains in the container, allowing for rapid and controlled freezing and thawing, minimizing exposure to air and using a heat exchanger or steam wand for gentle temperature management, integrated with a milking system for a closed circuit process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If milk is filled into a funnel after milking, then the milk can be processed and stored, but the milk is exposed to air and germs leading to contamination

Engineering Contradiction:
Improveease of processingVSAvoidgerm contamination
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent implements a closed circuit system where milk is transferred directly from the milking system into the storage container without exposure to air. The container is sealed and connected to the milking system through closed conduits, creating an inert environment that prevents germ contamination while maintaining ease of processing.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

2Productivity

If the basket with plastic bag is moved constantly in warm water for thawing, then the colostrum thaws within 15 minutes, but the process is time-consuming and requires manual intervention

Engineering Contradiction:
Improvethawing speedVSAvoidthawing time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical process of manually moving the basket with a temperature control element that remains stationary in the container. The element actively regulates temperature through automated heating or cooling, substituting manual mechanical agitation with an automated thermal control system that achieves faster and more consistent thawing.

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

Solution Approach 2:

The temperature control element is designed to automatically regulate the temperature of the milk without requiring manual intervention. The system self-adjusts heating or cooling based on the milk's thermal state, eliminating the need for constant manual movement and monitoring while maintaining optimal thawing speed.

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If the temperature control element is removed from the container after freezing, then the container can be cleaned, but multiple handling steps increase germ introduction risk

Engineering Contradiction:
Improveease of cleaningVSAvoidgerm contamination
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent integrates the temperature control element as a permanent, food-safe component of the container structure. The element is merged with the container walls or bottom, eliminating the need for removal during cleaning. This integration maintains ease of cleaning through dishwasher-safe design while preventing germ contamination by eliminating handling steps.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The temperature control element serves multiple functions: freezing, thawing, temperature maintenance, and integration with the cleaning process. As a permanent fixture, it can be cleaned alongside the container itself, eliminating the need for separate handling and reducing contamination risk while maintaining versatility in temperature control applications.

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

4Reliability

If pasteurized milk is cooled to inhibit germ growth, then germs are controlled, but the milk must be warmed up again for feeding

Engineering Contradiction:
Improvegerm controlVSAvoidwarming time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements a dynamic temperature control system that can switch between cooling and heating modes based on the milk's current temperature and storage requirements. The same temperature control element that cools milk for germ inhibition can immediately switch to heating mode when feeding is required, eliminating the need for separate warming equipment and reducing time loss.

Inventive Principle:
Principle #15Dynamics

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 enables quick and hygienic treatment of milk, reducing germ contamination and preserving nutrients, with the temperature control element ensuring efficient and even heating and cooling without the need for multiple handling steps.

Implementation Method 1
