Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing solutions for holding brushes between uses are often unstable and require two hands to attach, leading to issues like brush dropping and increased cleaning time, especially when they rely on attachments to liquid containers.

Innovation Solution

A device that securely attaches to the brush, allowing it to be supported over a paint container, featuring adjustable attachment arms and a bent front portion for stability, enabling one-handed operation and secure positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing brush holder devices are attached to liquid containers, then they provide brush support functionality, but they require two hands to attach and are unstable causing brush dropping

Engineering Contradiction:

Improvebrush holding stabilityVSAvoidattachment operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Instead of attaching the brush holder to the container (existing approach), this invention inverts the attachment direction by securing the holder directly to the brush handle. The holder becomes part of the brush assembly rather than a separate container attachment, fundamentally reversing the attachment paradigm to solve both stability and ease-of-operation issues.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The brush holder is designed to be self-attaching to the brush through a clamp mechanism that secures onto the brush handle. Once attached, the holder serves itself by providing built-in support structure that eliminates the need for two-handed attachment operations, allowing single-handed use while maintaining stability.

Inventive Principle:

Principle #25Self-service

2Reliability

If existing brush holder devices are attached to liquid containers, then they provide brush support, but they increase cleaning time

Engineering Contradiction:

Improvebrush support functionalityVSAvoidcleaning time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The brush holder is designed as a separable component that can be easily removed from the brush handle. This segmentation allows the holder to be detached for cleaning or replacement without requiring cleaning of the entire brush assembly, thereby reducing cleaning time while maintaining reliable brush support functionality.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If brush attachment devices are designed with adjustable components, then they improve adaptability to different brushes, but they increase device complexity

Engineering Contradiction:

Improvebrush compatibilityVSAvoidattachment mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The clamp mechanism incorporates adjustable parameters such as opening width and clamping force that can be modified to accommodate different brush handle sizes and shapes. These parameter adjustments are achieved through simple mechanical means like sliding adjustments or spring tension changes, providing high adaptability without significantly increasing device complexity.

Inventive Principle:

Principle #35Parameter changes

AI summary

A brush holder designed to hold brushes used to apply liquid coverings to surfaces. The holder is securely attached to the brush. The holder allows the brush to then be supported form the top of the liquid container. The holder further allows the distance between the brush and the container surface to be adjusted as required.
