Solution Overview

Problem

Existing single-dose ice cream machines have inefficiencies in dispensing time, require complex electronic controls, bulky structures, and suffer from pressure imbalances leading to incomplete dispensing and clogging, necessitating frequent cleaning.

Innovation Solution

A machine with a compact mixing and cooling unit featuring a disc-shaped selector element and air supply system to manage internal pressure, allowing rapid and complete dispensing, along with a heating system for cleaning, and a simplified structure to reduce costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple portions of food product are prepared simultaneously in a single batch, then productivity increases, but the ability to provide fresh, customized single portions decreases and food safety risks increase

Engineering Contradiction:
Improvepreparation speedVSAvoidfood safety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The food product is divided into multiple individual portions within a single preparation cycle. The apparatus prepares multiple discrete portions simultaneously from a bulk ingredient supply, allowing each portion to be freshly made and separately packaged. This segmentation enables both high productivity through parallel preparation and maintained food safety through individual portion control and reduced cross-contamination risks.

Inventive Principle:
Principle #1Segmentation

2Productivity

If food product is prepared in bulk and stored for later use, then productivity increases, but freshness and quality deteriorate

Engineering Contradiction:
Improvepreparation efficiencyVSAvoidfreshness
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The system prepares multiple portions in advance during off-peak hours or in bulk, then immediately packages and stores them in controlled environments. The preliminary preparation is followed by rapid packaging and storage, minimizing the time between preparation and consumption. This allows the system to maintain freshness while achieving preparation efficiency through batch processing.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If a complex multi-step preparation process is used to ensure food safety and quality, then reliability improves, but device complexity and preparation time increase

Engineering Contradiction:
Improvefood safetyVSAvoidprocess complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple food safety and quality control steps are merged into integrated processing stages. The apparatus combines functions such as mixing, cooking, cooling, and packaging into a single integrated system that performs multiple operations sequentially without requiring separate complex equipment. This merging reduces overall device complexity while maintaining comprehensive food safety and quality standards through unified process control.

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If single portions are prepared individually one at a time, then food safety and freshness are maintained, but productivity decreases

Engineering Contradiction:
Improvefood safetyVSAvoidpreparation speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The preparation system is segmented into multiple independent preparation channels that can operate simultaneously. Each channel prepares a single portion independently, maintaining food safety through separate processing, while the overall system achieves high productivity through parallel processing of multiple portions at the same time. This segmentation allows individual portion preparation without sacrificing speed.

Inventive Principle:
Principle #1Segmentation
