Brush With Integral Rotating Hanger in Handle Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paint brushes with external hangers are inefficient and awkward to open and close, especially for left-handed users, often requiring hand position changes when on a ladder, which can be unsafe and inconvenient.
Innovation Solution
A paint brush with an integral hanger that rotates within a channel passing through the neck portion, allowing easy one-handed operation and secure hanging on either side of the brush handle, featuring a hinged or spring-loaded mechanism for convenient opening and closing, and a beveled edge for easy placement on paint containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional external hanger is used on one side of the brush handle, then the brush can be hung on paint cans, but the hanger is awkward to open and close and requires hand repositioning especially for left-handed users
Solution Approach 1:
The hanger is positioned asymmetrically within the channel of the brush handle, allowing it to be opened and closed from either the left or right side. This asymmetric placement within a symmetric channel structure enables users of any handedness to access the hanger conveniently without requiring hand repositioning.
Solution Approach 2:
The hanger mechanism is designed to serve multiple users regardless of handedness. By allowing the hanger to be accessed from either side of the brush handle, it becomes a universal solution that adapts to both right-handed and left-handed painters, eliminating the need for separate designs for different user groups.
2Device complexity
If the hanger is fixed on one side of the brush handle, then the structure is simple, but it forces painters to change hand position when on a ladder which is unsafe and inconvenient
Solution Approach 1:
The hanger is designed with a hinge mechanism that allows it to move between open and closed positions. This dynamic capability enables the hanger to be accessed from either side of the brush handle, providing operational flexibility without significantly increasing structural complexity. The hinge allows smooth transitions between positions while maintaining a relatively simple overall structure.
3Adaptability or versatility
If a channel passing through the neck portion is used to mount the hanger, then the hanger can rotate to either side for easy access, but the manufacturing complexity increases
Solution Approach 1:
The brush handle is segmented into distinct functional zones: the gripping portion for hand holding, the neck portion containing the channel for hanger mounting, and the ferrule with bristles for painting. This segmentation allows the channel to be precisely positioned in the neck portion without complicating the overall manufacturing process, as each section can be formed and assembled independently.

AI summary
A brush is disclosed having an integral hanger. The brush has a handle including a gripping portion and a neck portion, a ferrule, bristles coupled to the neck portion via the ferrule, and a channel within the handle which passes completely through the handle. A hanger assembly is provided which is hingedly mounted at a first end thereof within the channel and which includes one or more arm elements adapted to rotate between a position completely within the channel to positions on either a first side of the handle outside of the channel and/or a second side of the handle outside of the channel, the one or more arm elements are adapted to securely hold the brush on a lip of a container when the one or more arm elements are rotated to the first position and/or to the second position.
