Solution Overview

Problem

Current paint brush holders are cumbersome, lack easy access and storage, and are not compact for travel, failing to provide a convenient way to combine brush storage with a water supply, which is essential for cleaning and hydration in painting.

Innovation Solution

A universal paint brush holder that attaches to a mason jar, providing a compact solution with a lid and threaded band for easy setup and transport, featuring holes for vertical brush storage and grooves for horizontal rest, allowing for easy access to brushes and water, reducing space requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional paint brush holders are used, then brushes can be held, but the device is clunky and does not provide easy access or storage

Engineering Contradiction:

Improveeasy access to brushesVSAvoidclunky structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the brush holder and water container into a single integrated unit. The rigid sheet with holes for brushes is mounted directly on the mason jar lid, eliminating the need for separate brush holder and water container. This merging reduces device complexity while maintaining ease of access to both brushes and water.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The mason jar lid serves multiple functions: it holds the brush holder structure and simultaneously serves as the container for water supply. The rigid sheet mounted on the lid provides both structural support for brushes and integrates with the universal mason jar opening, creating a multi-functional device that simplifies the overall system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Volume of moving object

If separate brush holder and water container are used, then functions are complete, but space requirements are large and not compact for travel

Engineering Contradiction:

Improvecompact size for travelVSAvoidcombination of brush and water storage

Core Design Contradiction:

Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The brush holder and water container are merged into a single compact unit by mounting the rigid sheet with brush holes directly on the mason jar lid. This integration reduces the overall volume required for transport while maintaining both brush storage and water supply functions, making it suitable for travel.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If brushes are stored vertically only, then storage is simple, but access and organization are limited

Engineering Contradiction:

Improveaccess to brushesVSAvoidholder structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The rigid sheet features holes of varying diameters distributed across its surface, allowing different brush sizes to be stored vertically in appropriate holes. This local variation in hole sizes provides organized storage and easy access to different brushes without complicating the overall holder structure.

Inventive Principle:

Principle #3Local quality

AI summary

A paint brush holder includes a rigid sheet with a first surface and a second surface. The holder has a ledge surrounding an aperture that accommodates a mouth of a regular mouth mason jar, recessed with respect to the first surface. Grooves extend across a portion of the first surface on a first side of the aperture. Holes extend through the rigid sheet on a second side of the aperture opposite the grooves. The holes have a diameter larger than a smallest diameter of a paint brush handle and smaller than a largest diameter of the paint brush handle.
