Solution Overview

Problem

Stand mixers lack an efficient and easy-to-use ice cream making solution that ensures high-quality results without compromising the functionality and simplicity of the appliance.

Innovation Solution

An ice cream maker fitting for a stand mixer featuring a main body with a mobile element rotating about a first axis, coupled via a magnetic adapter element to a blade for processing ingredients, allowing for stable and efficient operation during planetary movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a magnetic coupling is used to attach the adapter element to the mobile element, then the blade is firmly coupled during planetary movement, but the device complexity increases due to the introduction of magnetic components

Engineering Contradiction:
Improvecoupling stabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical coupling mechanisms (screws, clips, or interlocking parts) with a magnetic coupling system. The adapter element contains a magnet that magnetically couples to the mobile element, providing firm attachment during planetary movement while eliminating complex mechanical fastening components. This substitution maintains coupling reliability while actually reducing overall device complexity.

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

2Adaptability or versatility

If a specialized ice cream maker fitting is added to the stand mixer, then ice cream making functionality is enabled, but the ease of operation decreases due to additional mounting and setup steps

Engineering Contradiction:
ImprovefunctionalityVSAvoidease of operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The adapter element is designed with a universal interface that couples to the stand mixer's mobile element through magnetic attraction. The same adapter can accommodate different blade types (ice cream blades, mixing blades, etc.), allowing one component to serve multiple functions. This multi-functionality approach enables ice cream making capability while maintaining ease of operation, as users can quickly swap between different blade types using the same magnetic adapter system without complex reconfiguration.

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

3Ease of manufacture

If the adapter element is designed with a simple magnetic coupling, then the ease of manufacture increases, but the strength of the coupling may be insufficient for high-speed planetary movement

Engineering Contradiction:
Improveease of manufactureVSAvoidcoupling strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The magnetic coupling strength can be adjusted by changing parameters such as magnet size, magnet material properties, and spacing between magnetic components. These parameter changes allow optimization of coupling strength for high-speed planetary movement while maintaining the simplicity and ease of manufacture of the magnetic coupling design. Stronger magnets or optimized magnetic circuit designs can provide sufficient coupling force without adding mechanical complexity.
