Blender Paddle Blade Assembly for Cavitation-Free Circulation

Solution Overview

Problem

Conventional blending appliances experience cavitation and solidification of ingredients in areas remote from the blade configuration at the bottom of the blending jar, which affects the blending process.

Innovation Solution

A blade assembly with upper and lower blade elements positioned on a central shaft, including U-shaped top and bottom blades, an S-shaped middle blade, and winged working members that extend radially and are twisted, preventing cavitation by enhancing ingredient circulation and processing efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional blade configuration is used at the bottom of the blending jar, then blending function is provided, but cavitation and solidification occur in areas remote from the blade configuration

Engineering Contradiction:

Improveblending performanceVSAvoidcavitation

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The blade assembly is segmented into multiple functional components: lower blade elements (including top, middle, and bottom blade forms) and upper working elements (including top and lower working members with wing portions). This segmentation allows different parts of the assembly to address different problems - the lower blades provide traditional blending while the upper working elements prevent cavitation in remote areas of the blending jar.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention extends the blending action from the traditional bottom-only location to upper dimensions by positioning working elements at the second end of the central shaft. The wing portions extend radially and are twisted at angles, creating multi-dimensional flow patterns that reach remote areas of the blending jar and eliminate cavitation zones.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

If conventional blade design is used, then blending function is achieved, but solidification of ingredients occurs in areas remote from the blade configuration

Engineering Contradiction:

Improveblending performanceVSAvoidingredient consistency

Core Design Contradiction:

ProductivityVSStability of the object's composition

Solution Approach 1:

The blade assembly is segmented into multiple functional components: lower blade elements (including top, middle, and bottom blade forms) and upper working elements (including top and lower working members with wing portions). This segmentation allows different parts of the assembly to address different problems - the lower blades provide traditional blending while the upper working elements prevent cavitation in remote areas of the blending jar.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The multi-component blade assembly creates continuous circulation patterns throughout the entire blending jar, from bottom to top and from center to periphery. The twisted wing portions and radial extensions ensure that the blending action is continuous and reaches all areas, preventing ingredient solidification in remote zones.

Inventive Principle:

Principle #20Continuity of useful action

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The invention extends the blending action from the traditional bottom-only location to upper dimensions by positioning working elements at the second end of the central shaft. The wing portions extend radially and are twisted at angles, creating multi-dimensional flow patterns that reach remote areas of the blending jar and eliminate cavitation zones.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The upper working elements act as intermediaries that transfer the rotational energy from the motor through the central shaft to the blending ingredients in upper and remote areas. The wing portions create flow patterns that mediate between the central rotation and the peripheral ingredients, preventing cavitation.

Inventive Principle:

Principle #24Intermediary (Mediator)
