Solution Overview

Problem

Existing ice cream makers face challenges in easily filling and removing the dessert mixture, and they often produce ice cream of a single hardness, making it difficult to achieve desired consistency and texture variations.

Innovation Solution

A device with a rotatable paddle and a cooling chamber that uses sensors to detect the hardness of the ice cream mixture, controlling the paddle and cooling elements to maintain a selected hardness, and allows for easy filling and removal of the mixture through a removable bucket system with a pivoting paddle mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a fixed paddle mechanism is used in traditional ice cream makers, then the structure is simple, but it is difficult to remove the frozen dessert from the reservoir

Engineering Contradiction:
Improveease of dessert removalVSAvoidpaddle mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The paddle assembly is made movable relative to the reservoir, transitioning from a static fixed position to a dynamic removable position. The paddle can be detached from the drive shaft and removed along with the frozen dessert, solving the difficulty of dessert removal while maintaining operational simplicity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The paddle mechanism is divided into separable components: the paddle assembly that contacts the dessert and the drive shaft that provides power. This segmentation allows the paddle to be removed independently with the dessert while the drive mechanism remains in the reservoir.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If traditional ice cream makers use a single freezing mechanism, then the device is simple, but they can only produce ice cream of a single hardness

Engineering Contradiction:
Improveice cream hardness selectionVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system allows adjustment of freezing parameters including temperature and freezing time to produce ice cream at different hardness levels. The processor module controls the freezing process parameters to achieve user-selected consistency and texture variations.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

A sensor module detects the hardness of the ice cream mixture during freezing and provides feedback to the processor module, which adjusts the freezing process to maintain the selected hardness level, enabling versatile ice cream production.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If a sensor module and processor module are added to control hardness, then adaptability improves, but device complexity increases

Engineering Contradiction:
Improvehardness control capabilityVSAvoidelectronic control complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sensor module replaces manual hardness assessment with automated detection, and the processor module replaces manual control adjustments with automated electronic control of the freezing process, improving adaptability while keeping the interface simple.

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

AI summary

An apparatus for making a frozen dessert. The apparatus including a reservoir located within a chassis for receiving a liquid dessert mixture and a rotatable paddle located within the reservoir. The paddle can have a body coupled to at least one respective scraper element by a living hinge, such that the scraper element has a scraping edge that is radially-outward biased by the living hinge for abuttingly engaging a wall of the reservoir. The reservoir and the axis of rotation can be substantially horizontally directed, with a substantially vertically-orientated lid closing an opening of the reservoir, the lid defining an aperture for receiving the mixture or enabling egress of the frozen dessert.
