Solution Overview

Problem

Existing ice cream production methods lack simplicity and flexibility for making small quantities, and they often pose risks of product contamination, which compromises food safety.

Innovation Solution

A batch freezing unit with a processing container, stirrer, thermal treatment system, and a system for receiving and housing capsules containing concentrated ice cream preparations, along with a device for injecting dilution liquids, allowing for on-demand production of small ice cream quantities while minimizing handling and contamination risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional ice cream production methods are used, then production capacity is sufficient for large quantities, but the complexity of operation increases and contamination risks arise

Engineering Contradiction:
Improvesimplicity of operationVSAvoidcomplexity of production system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The invention divides the ice cream production system into modular components: individual capsules containing concentrated preparation, a receiving device for multiple capsules, a processing container for mixing and freezing, and dispensing means. This segmentation allows simple operation with individual capsules while maintaining scalability for different production quantities.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention uses disposable capsules containing concentrated ice cream preparation. Each capsule is a single-use component that is inserted into the receiving device, used once, and then discarded. This eliminates the need for complex cleaning and sterilization procedures, greatly simplifying operation and reducing contamination risks.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Reliability

If traditional production methods are used, then food safety maintenance is difficult, but switching to capsule-based systems increases device complexity

Engineering Contradiction:
Improvefood safetyVSAvoidcomplexity of capsule handling system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The disposable capsule system ensures food safety by providing a sealed, single-use container for the concentrated preparation. Each capsule is hermetically sealed until use, preventing contamination during storage and handling. After use, the capsule is discarded, eliminating cross-contamination risks between batches.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The invention extracts the preparation from bulk storage containers and places it into individual sealed capsules. This extraction isolates the preparation from potential contamination sources in the environment and in previous batches, maintaining food safety while using a relatively simple capsule handling system.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If bulk production is used, then production efficiency is high, but the ability to produce small quantities on demand is reduced

Engineering Contradiction:
Improveproduction speedVSAvoidflexibility for small quantities
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The receiving device is designed to accept multiple capsules simultaneously, and the processing container can handle different numbers of capsules based on demand. This segmentation allows the system to produce small quantities using one or two capsules or large quantities using multiple capsules, providing both speed and flexibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically adapts to production requirements by allowing the operator to insert the appropriate number of capsules into the receiving device based on customer demand. The processing container then processes whatever quantity is present, enabling rapid adjustment between small and large production quantities without changing the fundamental system.

Inventive Principle:
Principle #15Dynamics

4Ease of manufacture

If conventional mixing systems are used, then mixing capability is sufficient, but cleaning and maintenance complexity increases

Engineering Contradiction:
Improveease of cleaningVSAvoidcomplexity of mixing system
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The disposable capsules eliminate the need for complex cleaning procedures. The concentrated preparation is sealed in the capsule until use, preventing contact with the external environment and the mixing system. After use, only the processing container needs simple cleaning, not the preparation storage and handling systems.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The invention extracts the preparation from bulk containers and delivers it through sealed capsules directly to the processing container. This extraction eliminates the need for complex piping, pumps, and cleaning systems that would be required to handle bulk preparations, simplifying both the mixing system and its maintenance.

Inventive Principle:
Principle #2Taking out (Extraction)
