Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional food processors with rotating blades face issues of rotational wear and limited flexibility in transmission systems, as the upper end of the processing assembly is free to rotate relative to the container lid, leading to potential damage and limited customization of speed ratios.

Innovation Solution

A food processing apparatus where a portion of the processing assembly is rotationally fixed relative to the container lid in both rotational directions, allowing for a transmission system to be integrated within the container, enabling easy exchange of different speed ratios and reducing rotational wear by maintaining the end of the processing assembly stationary during operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the upper end of the processing assembly is free to rotate relative to the container lid, then the processing assembly can be easily installed and removed, but rotational wear occurs and reliability deteriorates

Engineering Contradiction:

ImproveInstallation and removal of processing assemblyVSAvoidRotational wear resistance

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The processing assembly is divided into a stationary upper end portion (attached to lid) and a rotating lower end portion (with blades), allowing the stationary part to prevent wear while the rotating part performs processing function

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rotating functional elements (blades) are extracted from the upper end connection structure and placed in the lower end, separating the connection function from the processing function to eliminate rotational wear at the connection point

Inventive Principle:

Principle #2Taking out (Extraction)

2Adaptability or versatility

If a transmission system is integrated within the container, then flexibility in speed ratios is improved, but device complexity increases

Engineering Contradiction:

ImproveSpeed ratio customizationVSAvoidTransmission system structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The transmission system is nested within the container body, utilizing the existing container space to house additional mechanical components without significantly increasing overall device footprint

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The transmission system is designed to work with different processing assemblies having various speed ratios, allowing a single transmission unit to support multiple processing functions and configurations

Inventive Principle:

Principle #6Universality (Multi-functionality)
