Solution Overview

Problem

Existing brush cleaning methods require manual handling, which can harm the user's hands and damage brush bristles, and lack a universal solution for different types of brushes.

Innovation Solution

A brush cleaning device with movable rollers that squeeze and smooth the brush head without penetrating it, allowing controlled fluid removal into a container, compatible with various brush types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If teeth are used to penetrate and separate brush bristles, then paint removal is achieved, but brush bristles are damaged and torn

Engineering Contradiction:

Improvepaint removal efficiencyVSAvoidbrush bristle integrity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent introduces an intermediary substance (solvent or water) and a containment structure (cup or container) to mediate the cleaning process. The solvent is applied to the brush bristles through the cup, allowing paint to dissolve and be removed without direct mechanical penetration of teeth into the bristles, thus preventing damage while maintaining cleaning effectiveness.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical tooth-penetration system with a chemical dissolution system. Instead of using teeth to mechanically separate and remove paint from bristles, the system uses solvent chemistry to dissolve paint, which then flows out through the cup structure, eliminating direct mechanical stress on the bristles.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If manual squeezing and smoothing of brush bristles is performed, then paint and fluid removal is achieved, but user hands are exposed to harmful paints and solvents

Engineering Contradiction:

Improvefluid removal efficiencyVSAvoiduser hand exposure to chemicals

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The cup or container structure serves as an intermediary between the user's hands and the brush bristles. The user holds the cup while the brush is inserted, allowing squeezing and smoothing actions to be performed on the brush through the cup structure rather than directly with hands, thus preventing exposure to paints and solvents while maintaining cleaning effectiveness.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of manufacture

If traditional water rinsing or solvent submersion is used, then paint cleaning is achieved, but additional fluid handling and mess management are required

Engineering Contradiction:

Improvecleaning process simplicityVSAvoidfluid containment and management

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges the cup or container structure with the brush cleaning function, combining fluid containment, application, and removal capabilities into a single integrated device. This eliminates the need for separate containers and manual fluid management steps, simplifying the overall cleaning process while maintaining effective paint removal.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A brush cleaning device is disclosed. The brush cleaning device has a first arm and a second arm extend along a central axis and that are connected and movable between an open position and a closed position. A first roller is attached to the first arm to be rotatable about a first roller axis, and a second roller is attached to the second arm to be rotatable about a second roller axis, wherein the axis of rotation for each roller is generally perpendicular to the central axis. A closable gap is formed between the first roller and the second roller in the open position, wherein a brush head can be engaged on each side by the two rollers moving to the closed position, whereby the two rollers can then simultaneously smooth the brush head and squeeze of fluid out of the brush head in a controlled manner.
