Solution Overview

Problem

Natural peanut butter separates quickly into solids and liquids, requiring manual mixing which is messy and inconvenient for consumers, and existing solutions involve unhealthy additives to prevent separation.

Innovation Solution

A powered apparatus that rotates a closed container of food spread, using a drive roller and idler roller to evenly distribute solids and liquids, driven by a DC motor or alternative power sources, with adjustable rotation rates and alignment mechanisms to ensure effective mixing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If natural peanut butter is made without hydrogenation or stabilizers, then the food contains healthier fats, but the oils separate quickly from the solids requiring manual mixing

Engineering Contradiction:

Improveunhealthy fatsVSAvoidmanual mixing

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The apparatus enables the peanut butter to mix itself automatically through rotation, eliminating the need for manual consumer intervention. The drive roller rotates the jar to continuously circulate the contents, allowing the product to self-mix and maintain homogeneous consistency without consumer effort.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The apparatus performs mixing action in advance by continuously or periodically rotating the jar to prevent separation before consumption. This preliminary mixing action ensures the peanut butter remains ready-to-eat without requiring subsequent manual mixing by the consumer.

Inventive Principle:

Principle #10Preliminary action

2Stability of the object's composition

If manual stirring is used to mix separated peanut butter, then the solids and liquids are combined, but the process is messy and inconvenient

Engineering Contradiction:

Improvehomogeneous distributionVSAvoidmixing convenience

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The system automates the mixing function that previously required manual consumer action. The motorized drive roller rotates the jar to circulate contents automatically, transferring the mixing task from the consumer to the apparatus and eliminating messiness and inconvenience.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical stirring action with an automated rotational mechanism. Instead of a consumer inserting and rotating a spoon or utensil, an electric motor drives a roller that rotates the entire jar, substituting human mechanical action with an automated mechanical system.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Stability of the object's composition

If additives like emulsifiers or palm oil are added to prevent separation, then the peanut butter remains stable, but the food contains unhealthy fats

Engineering Contradiction:

Improveprevention of separationVSAvoidunhealthy fats

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent removes the need for chemical additives by extracting the separation problem through mechanical means. Instead of adding emulsifiers or stabilizers to chemically prevent separation, the system uses rotational mechanics to continuously circulate and redistribute solids and liquids, eliminating the need for unhealthy additives.

Inventive Principle:

Principle #2Taking out (Extraction)

4Ease of operation

If a powered apparatus rotates the container to mix the spread, then manual mixing is eliminated, but device complexity increases

Engineering Contradiction:

Improveautomatic mixingVSAvoidapparatus structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The drive roller serves multiple functions: it provides structural support for the jar, acts as the driving element for rotation, and functions as a mixing mechanism through its rotational motion. This multi-functionality reduces the need for separate components and simplifies the overall apparatus structure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The drive roller acts as an intermediary between the motor and the jar contents. Rather than the motor directly contacting or stirring the peanut butter, the roller mediates the transfer of rotational motion to the jar, which then circulates the contents. This intermediary approach simplifies the mixing mechanism while maintaining effectiveness.

Inventive Principle:

Principle #24Intermediary (Mediator)
