Solution Overview

Problem

Existing ice cream machines fail to efficiently produce single-dose products in a short time without waste or preservatives, while ensuring hygiene, safety, and adaptability to various shop sizes, and lack user-friendly operation and cleaning ease.

Innovation Solution

A method and machine for making single-dose gelato using a batch freezing chamber with a stirrer and thermal system, allowing preloading of a base mixture at near-zero temperatures, simultaneous cooling and stirring, and flavoring addition, controlled by a user interface, to produce high-quality gelato in a short time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional ice cream machines are used to make single-dose products, then the production time is long and waste occurs, but the requirement is to produce quickly without waste

Engineering Contradiction:
Improveproduction speedVSAvoidturnaround time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The machine pre-cools the freezing chamber to sub-zero temperatures before each single-dose production cycle. This preliminary cooling action eliminates the need to heat and re-cool the chamber during production, dramatically reducing turnaround time and enabling rapid single-portion制作 without waste

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The machine is designed for single-dose production rather than batch processing, segmenting the ice cream production into individual portions. This allows precise control of small quantities (50-550g) and eliminates waste by producing only what is needed, while maintaining high productivity through rapid cycling

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the machine is made compact for small shop spaces, then adaptability improves, but the machine must still perform complex freezing and stirring functions

Engineering Contradiction:
Improvespace adaptabilityVSAvoidfreezing chamber complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The machine merges the freezing chamber, stirrer mechanism, and dispensing system into a single compact integrated unit. The horizontal cylindrical chamber combines cooling and stirring functions in one space, eliminating the need for separate equipment while maintaining complex functionality for high-quality single-dose production

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The freezing chamber serves multiple functions: it cools the mixture to sub-zero temperatures, maintains the mixture in a semiliquid standby state, performs simultaneous cooling and stirring during production, and houses the dispensing valve. This multi-functionality in a single component enables compact design while maintaining versatility

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

3Productivity

If the base mixture is kept at very low temperatures to reduce processing time, then productivity improves, but the mixture may freeze solid

Engineering Contradiction:
Improveprocessing speedVSAvoidmixture state stability
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The machine precisely controls the temperature parameter of the base mixture, maintaining it in a semiliquid state between -5°C and 5°C. This parameter control prevents the mixture from freezing solid while enabling rapid processing. The stirrer continuously agitates the mixture to maintain proper consistency and prevent crystallization during storage and production

Inventive Principle:
Principle #35Parameter changes
