Cleaning Brush With Flexible Bristles For Sharp Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning brushes are inadequate for efficiently cleaning thin edge tools with sharp edges, as they can cut through towels or sponges and are difficult to maneuver due to their awkward design.
Innovation Solution
A cleaning brush with a rigid base and flexible bristles, featuring a coupler that divides the bristle area and a scraper for removing excess material, allowing for safe and efficient cleaning of both thin and thick tools by agitating contaminants between the bristles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a towel or sponge is used to clean tools with sharp edges, then the cleaning process is simple, but the towel or sponge can be cut and the user safety is compromised
Solution Approach 1:
The patent introduces a cleaning brush as an intermediary tool between the user and the sharp-edged tools. The brush has a rigid base that protects the user's hand from sharp edges while flexible bristles perform the cleaning function, thus mediating between safety requirements and cleaning effectiveness.
Solution Approach 2:
The patent uses flexible bristles that can conform to the surface of tools being cleaned. These flexible elements adapt to various tool geometries including sharp edges, providing both protection to the user and effective cleaning contact with the tool surface.
2Productivity
If a traditional brush is used to clean tools, then some cleaning capability is provided, but awkward design makes them difficult to maneuver
Solution Approach 1:
The patent employs flexible bristles that dynamically adapt to the contours and geometry of different tools. This dynamic flexibility allows the brush to maneuver around sharp edges and awkward shapes while maintaining cleaning contact, resolving the contradiction between cleaning capability and ease of operation.
3Strength
If a rigid brush is used to clean tools with sharp edges, then durability is improved, but it can damage the tools being cleaned
Solution Approach 1:
The patent applies different material properties to different parts of the brush: the base is rigid to provide durability and protect against sharp edges, while the bristles are flexible to prevent damage to the tools being cleaned. This local differentiation of material properties resolves the contradiction between brush durability and tool protection.
Solution Approach 2:
The brush combines rigid and flexible materials in a single tool, creating a composite structure where each material performs its optimal function. The rigid base provides structural integrity and protection, while the flexible bristles provide gentle cleaning contact, together resolving the contradiction between strength and harm prevention.
4Productivity
If multiple cleaning tools are used for different tool sizes, then cleaning effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent designs a universal cleaning brush that can effectively clean various tool sizes and geometries through its flexible bristle design. The same brush adapts to different cleaning scenarios, eliminating the need for multiple specialized tools and resolving the contradiction between cleaning effectiveness and device complexity.

AI summary
A cleaning brush includes a rigid bottom base wall portion, side wall portions extending from opposite sides of the bottom base wall portion, a first rigid top wall portion extending from an upper end of one side wall portion, and a second rigid top wall portion extending from an upper end of the other side wall portion. A slot is provided between facing ends of the top wall portions which extends between first and second ends of the cleaning brush. A first set of first bristles extends from the bottom base wall portion, and second and third sets of bristles extend from the top wall portions. Free ends of the bristles may touch each other, be spaced from each other, or may extend past each other.
