Injection-Molded Makeup Brush Head Without Flocking Shedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional makeup brushes with flocking material brush heads have a complex production process and shed fluffs, affecting the makeup effect and user comfort.
Innovation Solution
The makeup brush head is integrally formed by injection molding, combining the holding portion, application portion, and bristles, omitting the flocking process and simplifying production, with optimized bristle lengths and diameters to prevent shedding and enhance application uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional flocking process is used to manufacture brush head, then the brush head can be produced with traditional materials, but the production process becomes complicated and production efficiency decreases
Solution Approach 1:
The patent combines the holding portion, application portion, and bristles into a single integrally molded component. The injection molding process creates all three elements in one continuous operation, eliminating the need for separate flocking processes and multiple assembly steps. This merging of components directly resolves the technical contradiction by simplifying the manufacturing process while simultaneously improving production efficiency.
2Reliability
If flocking material is used for bristles, then traditional brush head can be manufactured, but fluff shedding occurs affecting makeup effect and user comfort
Solution Approach 1:
The patent employs a specialized plastic material with elastic properties to create the bristles. This composite material approach allows the bristles to be integrally molded with the application portion while maintaining flexibility and softness. The elastic plastic material prevents fluff shedding inherent in traditional flocking materials, thereby improving reliability and eliminating harmful fluff shedding without compromising makeup application quality.
3Manufacturing precision
If bristles are made shorter and thinner through injection molding, then fluff shedding is prevented and application uniformity improves, but manufacturing precision requirements increase
Solution Approach 1:
The patent utilizes injection molding parameters to precisely control the dimensions of the bristles. By adjusting molding temperature, pressure, and cooling time, the process achieves consistent bristle lengths and diameters within tight tolerances. This parameter control enables the creation of short, fine bristles that do not shed, while maintaining manufacturing precision through process optimization rather than requiring post-manufacturing adjustments.

Function Achieved in This Case
This approach simplifies production, reduces manufacturing costs, and provides a more uniform and comfortable makeup experience by eliminating fluff shedding and ensuring soft bristles that do not hurt the skin.
Implementation Method 1
The holding portion, the application portion and the bristles are integrally formed into a plastic part by injection molding
Data Source
AI summary
A makeup brush head includes a holding portion and an application portion fixedly connected to the holding portion. Outwardly protruding bristles are distributed on the surface of the application portion. The holding portion, the application portion, and the bristles are integrally formed into a plastic part by injection molding. The bristles are configured for applying a cosmetic material. The makeup brush head omits the flocking process, simplifies the production process, improves the production efficiency and lowers the manufacturing cost.
