Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The accumulation of excess paint on paintbrush bristles leads to uneven and thick paint application, with existing solutions causing messy paint drips and lid replacement issues in paint cans.

Innovation Solution

A device attachable to the paint can's lip, featuring a clip portion and laterally extending arms for paintbrush contact, allowing excess paint to be returned to the can, preventing drips and facilitating easy lid replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the brush is used directly after being inserted into the paint, then the painting process is quick and simple, but the excess paint will drip and the paint application will be too thick and uneven

Engineering Contradiction:

Improvepainting speedVSAvoidpaint application quality

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent introduces an intermediary device (the paint removal member with arms) that mediates between the paintbrush and the paint can lip. This intermediary structure provides a controlled path for excess paint to be removed and returned to the can, preventing uncontrolled dripping while maintaining painting efficiency

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the paint removal function from the paint can lip itself and creates a separate, dedicated removal member. This extraction allows the removal function to be optimized independently, with arms that can be specifically designed to capture and redirect excess paint back to the can

Inventive Principle:

Principle #2Taking out (Extraction)

2Manufacturing precision

If the painter runs the sides of the brush against the inside lip of a paint can to remove excess paint, then the paint application quality improves, but paint drips down the side of the paint can or enters the lip, making lid replacement messy and frustrating

Engineering Contradiction:

Improvepaint application qualityVSAvoidpaint drippage and mess

Core Design Contradiction:

Manufacturing precisionVSObject-generated harmful factors

Solution Approach 1:

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent converts the harmful effect of excess paint (which would otherwise drip and create mess) into a beneficial outcome by providing arms that capture the dripping paint and redirect it back into the can. The harmful drippage is transformed into a controlled flow that conserves paint and prevents mess

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Loss of substance

If a paint removal device is added to the paint can, then excess paint can be effectively removed and returned to the can, but the device complexity increases with additional components

Engineering Contradiction:

Improvepaint wasteVSAvoiddevice structure

Core Design Contradiction:

Loss of substanceVSDevice complexity

Solution Approach 1:

The patent designs the removal member to perform multiple functions with a single structure: the arms both remove excess paint from the brush and provide a pathway for the paint to return to the can. The clip portion simultaneously attaches the device to the can and positions the arms correctly, reducing the need for additional components

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A paint removal device that allows for the removal of excess paint from a paintbrush for cleaner and more efficient painting. The paint removal device contains an attachment member to allow for the device to be secured to a lip of a paint can, and a removal member that includes a pair of arms extends laterally away from the clip portion. When attached to a paint can, the paint removal member is positioned to allow for a painter to draw the paintbrush against the side of the arms of the paint removal member to remove the excess paint from the paintbrush bristles after inserting the paintbrush into the paint supply.
