Modular Hair Brush Dispensing Viscous Styling Products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair treatment products are difficult to apply evenly and efficiently, especially at home, due to messiness and lack of control over product distribution, with existing solutions being bulky, leaky, and hazardous.
Innovation Solution
A modular hair brush assembly with a handle, replaceable brush heads, and a product insert that allows for controlled dispensing of viscous liquid products through bristles and openings, using a piston or slider mechanism for precise product application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spray nozzle is used to disperse liquid styling agent through a brush, then convenience of product and brush integration is improved, but overspray problem occurs and product use is limited to liquids
Solution Approach 1:
The brush is divided into multiple sections with different bristle densities and lengths, allowing different product application rates to different hair regions. The brush head contains multiple product reservoirs that can be independently controlled, enabling segmented product delivery rather than uniform overspray across the entire brush surface.
Solution Approach 2:
Different sections of the brush have tailored bristle properties (density, length, material) matched to specific hair types and product viscosities. Product reservoirs are strategically positioned to deliver product locally to specific brush zones, ensuring appropriate product distribution for different hair regions without causing overspray.
2Ease of operation
If pressurized product containers are used, then product dispensing control is improved, but hazard during transport especially on plane increases
Solution Approach 1:
The pressurized container is extracted from the brush assembly, with only the brush head and product reservoirs remaining integrated. The pressurized canister is held separately and applied to the brush head only when needed, eliminating the hazard of transporting pressurized containers while maintaining controlled product dispensing during application.
Solution Approach 2:
The brush head acts as an intermediary between the pressurized container and the hair. The pressurized product is first transferred to the brush's internal reservoirs, then dispensed through the bristles onto the hair. This intermediary system allows controlled dispensing without requiring the pressurized container to be integrated with the brush during transport.
3Ease of operation
If a toothbrush or small applicator is used to transfer product to hair, then product application control is improved, but messiness and time consumption increase
Solution Approach 1:
The product reservoirs and brush head are merged into a single integrated unit. Product is stored within the brush head itself in multiple compartments, eliminating the need to separately dip an applicator into product containers. The user simply applies the brush directly to hair, combining product pickup and application into one action, thereby reducing both messiness and time consumption.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient, controlled, and mess-free application of hair treatment products, providing better control over product distribution and compatibility with different hair types, while being safe and convenient to use.
Implementation Method 1
an extruder assembly configured to move one or more viscous liquid hair treatment products from within the chamber through the plurality of openings on the brush surface onto the plurality of bristles of the brush head

AI summary
A modular hair brush for dispersing styling products, therapeutic, and medicated treatments from a product holder in a brush handle. The head portion of the brush includes bristles that are positioned near openings that disperse the treatment product(s) stored within the handle. When product application is desired, a manual push or twist mechanism is engaged, which causes one or more products to pass through the openings to the bristles of the brush and onto the hair during normal combing. Different examples provide for the use of replaceable brush heads that can be adjusted to different hair texture and thickness, or type of hair styling. A replaceable product insert can use different viscous liquid solutions designed for different treatment. The modular brush allows for mixing of different hair products before application, offering a portable, refillable, on-the-go multi-functional beauty tool.
