Alternating Loop and Bristle Hair Brush for Extension Protection

Solution Overview

Problem

Conventional hair brushes are not designed to handle hair with extensions, often causing damage or snagging of both natural hair and extensions during brushing and styling.

Innovation Solution

A hair brush with alternating loops and straight boar hair bristles or loops surrounded by boar hair bristles, which are designed to minimize damage and enhance shine, allowing for easier brushing and styling of hair with extensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional hair brushes are used on hair with extensions, then brushing and styling can be performed, but the hair extensions or natural hair may be damaged or pulled out

Engineering Contradiction:

Improvebrushing and styling capabilityVSAvoiddamage to hair extensions or natural hair

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The brush head is segmented into distinct functional zones: a first area with loops configured to engage and guide hair extensions, and a second area with bristles configured to engage and style natural hair. This segmentation allows each zone to perform its specific function without causing damage to either extensions or natural hair.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different parts of the brush have different local qualities suited to their specific functions. The loops in the first area have a smooth, continuous structure ideal for gliding through hair extensions, while the bristles in the second area have a different structure optimized for styling natural hair. This local differentiation prevents damage while maintaining styling effectiveness.

Inventive Principle:

Principle #3Local quality

2Shape

If hair extensions are installed to achieve long hair, then the desired hair length and style are achieved, but the process is time-consuming and requires special care during brushing and styling

Engineering Contradiction:

Improvehair length and styleVSAvoidtime for installation and maintenance

Core Design Contradiction:

ShapeVSLoss of time

Solution Approach 1:

The brush is designed with multi-functionality to handle both hair extensions and natural hair in a single tool. The combination of loops and bristles allows the brush to perform multiple functions: protecting extensions during brushing, styling natural hair, and maintaining the overall hairstyle, thereby reducing the time and complexity of maintenance routines.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of manufacture

If standard brush designs are used, then manufacturing is simple, but they are not designed for brushing or styling natural hair that has had hair extensions installed

Engineering Contradiction:

Improvebrush manufacturing simplicityVSAvoidadaptability to hair with extensions

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The brush head is segmented into distinct functional zones: a first area with loops configured to engage and guide hair extensions, and a second area with bristles configured to engage and style natural hair. This segmentation allows each zone to perform its specific function without causing damage to either extensions or natural hair.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different parts of the brush have different local qualities suited to their specific functions. The loops in the first area have a smooth, continuous structure ideal for gliding through hair extensions, while the bristles in the second area have a different structure optimized for styling natural hair. This local differentiation prevents damage while maintaining styling effectiveness.

AI summary

A hair brush is shown and disclosed. The hair brush has a row of loops on the first side running from near the handle to the top mounted in a retention material. Next to the row of loops, is located a row of bundles of boar bristles. These groupings of boar bristles are a bundle of individual boar bristles mounted in the retention material. This alternating pattern of lines or rows of loops and bristles continues to the other side of the brush and the last row near the second side is a row of loops. The loops can be configured such that they are parallel to the sides or the top. These rows of loops on the sides of the hair brush help to keep the hair brush from pulling on and possibly damaging the hair extensions that have been installed into a users natural hair. The bundles of boar bristles provide additional shine and manageability to the hair. Also shown is an arrangement of a single loop surrounded by a plurality of bristles and mounted in the retention material. The base of the brush can take many different shapes such as round, semi-circular, square and rectangular. The base can vary in size, wherein the base is large for salon use and smaller for personal carry use. The density of the loops and bristles can also be varied dependent upon the design criteria and type of hair or hair extensions.
