Integrated Pump Brush Applicator for Precise Hair Product Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair product application methods result in significant waste as users need to purchase separate containers and brushes for touch-ups, with only a small amount of product required to maintain uniform hair appearance, leading to inefficiency.
Innovation Solution
A hair product applicator featuring a pump and brushhead design where the pump includes a housing with a cavity for storing composition and a dispensing tip, coupled with a brushhead having bristle bores and a central throughhole, allowing precise dispensing of the composition onto bristle bundles when the cap is removed and the plunger is actuated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a separate container and brush are used for hair product application, then the product can be applied to hair, but a significant portion of the product is wasted because only a small amount is required for touch-ups
Solution Approach 1:
The patent combines the product container, dispensing mechanism, and brush into a single integrated applicator device. The brush is positioned within the container housing, and the pump mechanism dispenses product directly onto the brush bristles, eliminating the need for separate storage and application tools while minimizing product waste through controlled dispensing.
Solution Approach 2:
The applicator device is designed to automatically dispense the required amount of product onto the brush through a pump mechanism activated by the user. The system self-regulates the product transfer from the container to the brush, ensuring precise dosing without requiring the user to manually portion the product, thereby preventing both over-application and waste.
2Measurement precision
If a pump and brushhead design is used, then precise application of composition onto bristle bundles is achieved, but the device structure becomes more complex
Solution Approach 1:
The applicator is divided into distinct functional modules: a container housing for product storage, a pump mechanism for controlled dispensing, and a brushhead with bristle bundles for application. This segmentation allows each component to perform its specific function efficiently while maintaining overall system precision. The pump delivers exact amounts of product to specific zones of the brushhead, enabling precise application.
Solution Approach 2:
The pump mechanism serves as an intermediary between the product container and the brushhead, precisely controlling the transfer of composition. It meters the product flow and delivers it directly onto the bristle bundles in controlled amounts, ensuring accurate dosing without requiring complex external measuring devices or manual portioning.
3Reliability
If the composition is stored in the housing cavity, then the product is protected from ambient air and moisture, but the dispensing mechanism requires more components
Solution Approach 1:
The brushhead is nested within the container housing, and the pump mechanism is integrated into the housing structure. This nested arrangement allows the housing to serve dual purposes: as a protective enclosure that seals the composition from ambient air and moisture, and as a structural support for the dispensing mechanism. The tip with dispensing opening is positioned to deliver product directly to the brush bristles without requiring additional external components.
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
This design minimizes waste by allowing precise application of hair products directly onto the bristle bundles, enabling efficient touch-ups and extending the life of the product by preventing ambient air and moisture from interacting with the composition.
Implementation Method 1
The pump includes a housing and a plunger. The housing has (i) an upper opening, (ii) a cavity configured to store a composition therein, and (iii) a tip having a dispensing opening. The plunger is slidably disposed within the housing such that the plunger is moveable with respect to the housing and aids in preventing the composition from escaping through the upper opening of the housing.
Implementation Method 2
The tip of the housing is sealed with a cap.

AI summary
A device includes a pump and a brushhead. The pump includes a housing and plunger. The housing has an upper opening, a cavity configured to store a composition therein, and a tip having a dispensing opening. The plunger is slidably disposed within housing such that it is moveable with respect to the housing. The brushhead includes a first plurality of bristle bores and a second plurality of bristle bores, each of which extend from a bottom surface of the brushhead towards an opposing top surface and have a bristle bundle extending therefrom. The brushhead includes a generally central throughhole extending between the bottom surface and the opposing top surface. The pump is coupled to the brushhead via the tip of the housing such that actuation of the plunger causes a portion of the composition stored in the housing to be dispensed on at least a portion of the bristle bundles.
