Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing paint brush holders and keepers require external attachment or transfer, occupying space and not utilizing the interior of paint containers for storage, and there is a need for a more efficient and space-saving method to store paint brushes during interruptions.

Innovation Solution

A support clip/brush holder assembly that mounts to the interior of a paint container, allowing vertical suspension of brushes, and a brush keeper kit using stacked paint containers with an adapter to create an interior space for wet storage, utilizing existing materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If traditional brush holders are used, then brushes can be stored, but the holder must extend to the exterior of the container occupying additional space

Engineering Contradiction:

Improvestorage space utilizationVSAvoidholder structure

Core Design Contradiction:

Volume of moving objectVSDevice complexity

Solution Approach 1:

The brush holder is nested within the paint container interior, with the support clip mounting to the inner sidewall and rim. The brush holder support section carries the brush holder completely inside the container, eliminating the need for external extension and maximizing space utilization.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If brush keepers are used to cover brushes, then brushes can be protected during wet storage, but the brush must be transferred to the brush keeper

Engineering Contradiction:

Improvebrush storage convenienceVSAvoidtime to transfer brush

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The paint container itself serves as the brush holder through the support clip mechanism. The container's rim and inner sidewall provide mounting surfaces that eliminate the need for separate brush holders or keepers, allowing brushes to be stored directly in the container without transfer.

Inventive Principle:

Principle #25Self-service

3Productivity

If brushes are placed in the paint container, then storage is simple, but volatile materials may escape

Engineering Contradiction:

Improvestorage efficiencyVSAvoidvapor release

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The support clip and brush holder assembly provides a structured mounting system that allows the container lid to seal properly. The clips mount to the rim and inner sidewall, creating a stable configuration that prevents vapor escape while maintaining container integrity.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A support clip includes a container engagement section for mounting the support clip to an upper interior portion of a paint container, and a brush holder support section. A brush holder carries a vertically suspended paint brush. Edge surfaces of the container engagement section include a first segment, a second segment, and an intermediate segment, which engage inner and lower surfaces of the container rim and an inner sidewall surface. A brush keeper kit for a paint brush employs used paint containers as brush keeper parts. The brush keeper kit includes a paint container adapter and a brush holder. The paint container adapter has an outer rim and an inner ledge, which define upper and lower sections for coupling upper and lower paint containers. The brush holder is mounted to an upper interior portion of the lower paint container and supports the paint brush within an interior space.
