Solution Overview

Problem

Existing storage devices for paint brushes do not effectively prevent the brushes from drying out while allowing for easy access and temporary storage during painting projects.

Innovation Solution

A cup with a clip and a hingedly attached cover that encloses the paint brush, preventing it from drying out and allowing for easy removal, along with a magnet for temporary storage during breaks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a paint brush is stored in a paint can using a simple clip, then the brush can be temporarily held, but the brush dries out quickly and is not protected from contamination

Engineering Contradiction:

Improvebrush moisture retentionVSAvoidstorage device structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into a single integrated storage device: the cup holds paint, the clip secures the brush handle, and the cover protects the brush bristles. This merging of functions provides comprehensive brush protection while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The brush is nested within the cup structure, with the bristles positioned inside the cup and the cover enclosing the bristles. This nesting arrangement protects the brush from drying out and contamination while keeping the device compact.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If the cover is tightly closed to protect the brush, then moisture is retained, but the brush becomes difficult to remove

Engineering Contradiction:

Improvebrush protectionVSAvoidbrush removal

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The cover is designed to be movable rather than fixed, allowing it to be opened for brush removal and closed for protection. This dynamic element enables the device to switch between protection mode and access mode, resolving the contradiction between secure enclosure and ease of removal.

Inventive Principle:

Principle #15Dynamics

3Reliability

If the clip holds the brush tightly, then the brush is securely stored, but the brush handle cannot be easily gripped for removal

Engineering Contradiction:

Improvebrush retentionVSAvoidhandle accessibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The clip is designed to engage only a portion of the brush handle, specifically the upper part, while leaving the lower handle portion exposed and accessible. This localized engagement provides secure retention during storage while maintaining easy accessibility for removal when needed.

Inventive Principle:

Principle #3Local quality

AI summary

A paint storage assembly for temporarily storing a wet paint brush includes a cup for containing liquid paint. A clip is attached to the cup and the clip releasably engages a paint brush for storing the paint brush. A cover is hingedly disposed on the cup and the cover is positionable in a closed position to enclose the paint brush thereby inhibiting the paint brush from drying out. The cover is positionable in an open position to facilitate the paint brush to be removed from the clip.
