Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Grinder heads in food processing appliances experience temperature rises due to friction, leading to bacterial growth and spoilage, as existing cooling methods like frozen packs do not effectively manage heat dissipation, causing performance issues and adhesion of ground food.

Innovation Solution

A cooling pack system with a heatsink is integrated into the grinder head, where the cooling pack extends circumferentially around the housing and includes gel-filled halves connected via straps for secure attachment, allowing for effective thermal heat transfer and heat dissipation to ambient air, maintaining the grinder head at a low temperature.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If frozen packs are used to cool the grinder head, then the grinder head temperature is reduced, but the cooling performance diminishes as the packs melt and cannot effectively dissipate heat

Engineering Contradiction:

Improvegrinder head temperatureVSAvoidcooling pack effectiveness duration

Core Design Contradiction:

TemperatureVSDuration of action of stationary object

Solution Approach 1:

The patent introduces a heatsink as an intermediary component between the grinder head and the cooling pack. The heatsink receives heat from the grinder head and transfers it to the cooling pack, which in turn dissipates heat to ambient air. This intermediary system allows for continuous heat management throughout the grinding process, resolving the contradiction between maintaining low temperature and extending cooling duration.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent adds a third dimension to the cooling system by incorporating ambient air cooling through heatsink fins. Instead of relying solely on the cooling pack's direct contact with the grinder head, the system extends into the ambient air space, creating a multi-dimensional heat dissipation pathway that maintains cooling effectiveness over extended periods.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Object-affected harmful factors

If frozen packs are used to cool the grinder head, then bacterial growth is reduced, but the packs require frequent replacement and do not allow heat to escape effectively

Engineering Contradiction:

Improvebacterial growthVSAvoidheat dissipation efficiency

Core Design Contradiction:

Object-affected harmful factorsVSLoss of energy

Solution Approach 1:

The heatsink acts as a mediator that facilitates continuous heat transfer from the grinder head to the cooling pack and finally to ambient air. This intermediary heat management system maintains lower grinder head temperatures to inhibit bacterial growth while efficiently dissipating heat energy throughout the grinding process, eliminating the need for frequent pack replacements.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a continuous heat dissipation pathway that operates throughout the entire grinding process. The heatsink continuously transfers heat to the cooling pack, which continuously dissipates heat to ambient air, ensuring uninterrupted cooling action that maintains food safety without energy loss from frequent pack changes.

Inventive Principle:

Principle #20Continuity of useful action

3Temperature

If a cooling pack is attached to the grinder head housing, then heat transfer is improved, but the pack may not conform to the cylindrical surface effectively

Engineering Contradiction:

Improveheat transfer efficiencyVSAvoidpack configuration match

Core Design Contradiction:

TemperatureVSShape

Solution Approach 1:

The patent designs the cooling pack with a curved configuration that conforms to the cylindrical outer surface of the grinder head housing. This curved geometry ensures maximum contact area between the cooling pack and the housing, improving thermal coupling and heat transfer efficiency while adapting to the cylindrical shape of the grinder head.

Inventive Principle:

Principle #14Spheroidality (Curvature)
