Solution Overview

Problem

Existing beverage brewing systems and home ice cream makers are inefficient in rapidly cooling single servings of food and drinks, requiring pre-cooling or pre-freezing and often necessitating extensive cleanup.

Innovation Solution

A refrigeration cycle-based system with a pod-machine interface that uses a refrigeration system with a working fluid loop and a mixing paddle to rapidly cool ingredients in a pod from room temperature to freezing in under two minutes, utilizing features like evaporators, compressors, and bypass lines, and capable of producing single servings of chilled or frozen foods and drinks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If existing beverage brewing systems or home ice cream makers are used, then single servings of food and drinks can be prepared, but the cooling process is inefficient and requires pre-cooling or pre-freezing

Engineering Contradiction:
Improvecooling speedVSAvoidpre-cooling time
Core Design Contradiction:
TemperatureVSLoss of time

Solution Approach 1:

The system changes the thermal parameters by using a refrigeration cycle that rapidly transfers heat from the pod contents to the evaporator, achieving temperature reduction from room temperature to freezing in under two minutes. The bypass line allows direct injection of cold refrigerant to accelerate the cooling process.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The evaporator acts as an intermediary heat transfer medium between the pod contents and the refrigeration system. The working fluid in the evaporator absorbs heat from the pod through thermal conduction, enabling rapid cooling without direct contact with the refrigerant.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If a refrigeration cycle system is used to rapidly cool pods, then cooling speed is improved, but the device complexity increases

Engineering Contradiction:
Improvecooling rateVSAvoidsystem structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system is divided into distinct functional modules: the refrigeration cycle components (compressor, condenser, expansion device, evaporator), the pod interface, and the bypass line system. This segmentation allows for optimized performance of each component while maintaining overall system manageability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The evaporator serves multiple functions: it acts as the heat exchange surface for rapid cooling, provides structural support for the pod interface, and facilitates the bypass line connection for direct refrigerant injection. This multi-functionality reduces the need for additional separate components.

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

3Ease of operation

If room temperature pods are used for single servings, then storage and handling are simplified, but rapid cooling to freezing is required

Engineering Contradiction:
Improvepod storageVSAvoidfinal cooling temperature
Core Design Contradiction:
Ease of operationVSTemperature

Solution Approach 1:

The pods are pre-filled and pre-sealed at room temperature with ingredients ready for processing. The sterilization and sealing are completed in advance during manufacturing, allowing the pods to be stored and handled without pre-cooling, and then rapidly cooled in the machine when needed.

Inventive Principle:
Principle #10Preliminary action
