Stepped Blender Cleaning Tool for Stepped Shaft Crevices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning tools, such as dish brushes and specialized blender brushes, are inadequate for effectively cleaning the difficult-to-reach areas under the blades of blenders with a stepped shaft, as they fail to reach and clean the small crevices and stepped regions efficiently.
Innovation Solution
A cleaning tool with a stepped arrangement of cleaning elements at different radii and heights, featuring a handle, angled neck, and a resilient over-mould with vertical blades and nodules, designed to match the geometry of the blender blade assembly, allowing for simultaneous cleaning of all surfaces under the blades.
Engineering Contradictions & Design Principles
Engineering 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
Solution Approach 1:
The cleaning tool divides the cleaning function into multiple segments: a first set of cleaning elements for one surface and a second set for another surface, allowing each segment to target specific areas of the blade assembly including hard-to-reach crevices
Solution Approach 2:
The tool transitions from conventional single-surface brushes to a multi-surface design with cleaning elements arranged to contact the blade assembly from multiple dimensions simultaneously, including top, bottom, and side surfaces
2Ease of operation
If dedicated blender brushes are used, then some improvement is achieved, but they offer minimal improvement over scaled down dish brushes
Solution Approach 1:
The cleaning tool is designed with universal applicability to clean all surfaces of the blade assembly including the blade itself, the shaft, and surrounding areas, making it a multi-functional tool that replaces multiple specialized brushes
Solution Approach 2:
The tool merges multiple cleaning functions into a single device by combining first and second sets of cleaning elements on one handle, integrating what would traditionally require multiple separate brushes into one unified tool

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.
