Solution Overview

Problem

Conventional cleaning tools, such as dish brushes and dedicated blender brushes, are ineffective in reaching and cleaning the small crevices beneath the blades of blenders with a stepped shaft, making it difficult to thoroughly clean these appliances.

Innovation Solution

A cleaning tool with a handle and head featuring two sets of cleaning elements at different heights and radii, comprising vertical blades or nodules, held by rigid arms, and an angled element to facilitate access and cleaning of the stepped shaft regions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional dish brushes are used to clean blender blades, then flat surfaces can be cleaned, but small crevices beneath the blades cannot be reached

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidaccess to crevices

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The cleaning tool divides the cleaning function into multiple segments with cleaning elements at different heights and radii. The head includes a first set of cleaning elements at a first height and radius, and a second set at a second height and radius, allowing each segment to target specific areas of the blade assembly including hard-to-reach crevices

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention adds vertical dimensionality to the cleaning tool by positioning cleaning elements at different heights above the base. This multi-level arrangement allows the tool to clean not only the horizontal surfaces but also the vertical faces and crevices of the stepped shaft and blade assembly

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If dedicated blender brushes are used, then some improvement is achieved, but minimal cleaning effectiveness remains due to similar design to dish brushes

Engineering Contradiction:

Improvecleaning improvementVSAvoidcleaning effectiveness

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Different parts of the cleaning head have different cleaning element configurations tailored to specific cleaning needs. The first set of cleaning elements targets one area while the second set targets another, with each set having properties optimized for its specific cleaning zone including varying heights, radii, and element types

Inventive Principle:

Principle #3Local quality

3Device complexity

If a single set of cleaning elements is used, then the tool structure is simple, but it cannot clean all surfaces including the step in the shaft

Engineering Contradiction:

Improvetool structureVSAvoidcomprehensive cleaning

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The cleaning head is segmented into multiple sets of cleaning elements positioned at different heights and radii. This segmentation allows the tool to comprehensively clean all surfaces including the stepped shaft, blade undersides, and base areas without requiring multiple separate tools

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple cleaning functions are merged into a single integrated head assembly. The first and second sets of cleaning elements, along with the angled element, work together in one tool to perform comprehensive cleaning of the entire blade assembly including areas that would otherwise require separate cleaning devices

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A tool with two sets of cleaning elements disposed at first and second radii about a common axis thus providing cleaning surfaces for all the spaces between a blender blade on a stepped shaft and its supporting base. Depending on the size of the step the cleaning elements are either vertical blades or nodules in the edge of a planar body.
