Applicator Recessed Portion Cosmetic Flow Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional applicators, such as lash and eyebrow brushes, waste cosmetic product when withdrawn from bottles, requiring frequent dipping for makeup application, which is inefficient.
Innovation Solution
An applicator design featuring a recessed portion that communicates with the bristles, allowing the cosmetic to flow from the recessed area to the bristles when the applicator is pulled out, increasing the amount of cosmetic carried with each use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a common applicator is used, then the structure is simple, but the applicator can only carry a small amount of cosmetic and requires frequent dipping
Solution Approach 1:
The applicator is divided into distinct functional zones: a mounting portion for structural support and an application portion with bristles for cosmetic delivery. This segmentation allows the application portion to be optimized for cosmetic storage and delivery without complicating the overall structure.
Solution Approach 2:
A recessed portion is added to the application portion, creating a three-dimensional cosmetic storage chamber. This dimensional addition allows the applicator to hold a larger volume of cosmetic while maintaining a compact overall structure that does not significantly increase complexity.
2Quantity of substance
If the applicator volume is increased to carry more cosmetic, then the cosmetic amount is sufficient, but the applicator structure becomes more complex
Solution Approach 1:
The recessed portion is nested within the application portion, creating a cosmetic storage chamber that utilizes the internal space of the applicator body. This nesting approach allows increased cosmetic volume without proportionally increasing the external dimensions or structural complexity of the applicator.
Solution Approach 2:
The application portion is designed with a flexible structure that can deform during withdrawal from the bottle. This flexibility allows the recessed portion to be squeezed by the inner plug, enabling cosmetic flow to the bristles without requiring complex mechanical release mechanisms.
3Productivity
If the recessed portion is squeezed by the inner plug, then the cosmetic flows to the bristles, but the applicator structure becomes more complex
Solution Approach 1:
The inner plug of the bottle serves a dual function: it seals the cosmetic when not in use and automatically squeezes the recessed portion during applicator withdrawal to release cosmetic onto the bristles. This self-service mechanism eliminates the need for separate release mechanisms, maintaining structural simplicity while improving productivity.
Solution Approach 2:
The sealing function and the cosmetic release function are merged into a single inner plug component. The same element that prevents cosmetic leakage during storage also activates the cosmetic transfer mechanism during use, reducing overall device complexity while enhancing makeup efficiency.
4Volume of stationary object
If the recessed portion is provided on the application portion, then the cosmetic storage capacity is increased, but the manufacturing complexity increases
Solution Approach 1:
The application portion serves multiple functions: it provides structural support, holds the bristles, stores cosmetic in the recessed portion, and deforms under squeezing to release cosmetic. This multi-functionality reduces the need for separate components, simplifying the manufacturing process while increasing cosmetic storage volume.
Solution Approach 2:
The manufacturing process utilizes material parameter changes, specifically the elasticity of the application portion material. By selecting materials with appropriate elastic properties, the recessed portion can be formed through deformation during molding, eliminating the need for complex multi-step manufacturing processes.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances makeup efficiency by reducing the frequency of dipping and ensuring a sufficient cosmetic amount is applied without compromising the makeup effect, while maintaining an aesthetically pleasing and high-end structure.
Implementation Method 1
the recessed portion passes through the inner plug, the inner plug squeezes the recessed portion, such that the cosmetic in the recessed portion flows to the bristles

AI summary
An applicator, a container including the applicator, and a mold for manufacturing the applicator are provided. The applicator includes a mounting portion and an application portion that are connected to each other. The application portion is provided with a first surface and a second surface that are opposite to each other. Bristles are arranged on the first surface. A recessed portion is provided on the application portion. The recessed portion communicates with the first surface, and the recessed portion is protruded from the second surface. The recessed portion is provided in the applicator. When the recessed portion passes through an inner plug, the inner plug squeezes the recessed portion, such that the cosmetic in the recessed portion flows to the bristles, and the bristles carry a large amount of the cosmetic when pulled out of the bottle.
