Multifunctional Cosmetic Brush With External Comb for Smooth Combing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic brushes with soft brush heads struggle to smoothly comb eyelashes or eyebrows due to excessive cosmetic material, making it difficult to achieve a better makeup effect and complicating the cleaning process.
Innovation Solution
A multifunctional cosmetic brush design with a comb fixed on the outer lid, featuring comb teeth extending outward along the axial direction, allowing direct combing of hair without rotating the bottle assembly, and a removable top lid for easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the brush head is made soft to apply cosmetic material, then the cosmetic application function is improved, but the combing smoothness deteriorates due to excessive cosmetic material
Solution Approach 1:
The device is divided into separate functional components: a soft brush head for cosmetic application and a separate comb structure for combing. The comb is positioned outside the outer lid, allowing independent operation from the brush head, thus resolving the conflict between soft brush performance and combing smoothness.
Solution Approach 2:
The comb is extracted from the traditional integrated brush structure and positioned as a separate component on the outer lid. This extraction allows the comb to operate independently without being constrained by the soft brush head, enabling smooth combing while the brush head maintains its cosmetic application function.
2Device complexity
If the comb is integrated inside the outer lid, then the structure is compact, but the combing operation and cleaning become difficult
Solution Approach 1:
The comb is extracted from the inner lid structure and repositioned on the outer lid, making it accessible for operation and cleaning. This positioning allows users to easily reach the comb for combing operations and cleaning without disassembling the entire device, while the overall structure remains compact.
Solution Approach 2:
The comb is positioned in a different spatial dimension (on the outer lid rather than inside the inner lid), making it externally accessible. This dimensional repositioning allows for easy operation and cleaning while maintaining the compact overall structure of the cosmetic brush device.
3Device complexity
If the comb teeth extend radially, then the structure is simple, but the combing operation requires rotating the bottle assembly
Solution Approach 1:
Instead of having comb teeth extend radially from the center, the comb teeth extend axially outward from the outer lid along the longitudinal axis. This inverted arrangement allows the comb to function directly without requiring rotation of the bottle assembly, significantly improving combing convenience while maintaining structural simplicity.

AI summary
The provided is a multifunctional cosmetic brush and a cosmetic container including the multifunctional cosmetic brush. The multifunctional cosmetic brush includes a comb, an outer lid, and an application assembly, where the comb is fixedly provided on the outer lid; the application assembly is fixedly provided on the outer lid; the comb includes a comb tooth; the comb tooth includes a first root portion and a first end portion; the first root portion is fixedly provided on the outer lid; the first end portion extends outward from the outer lid along an axial direction of the outer lid; and the first end portion is a free end. Since the comb is provided individually, the multifunctional cosmetic brush combs the hair well to achieve the better cosmetic effect. Moreover, since the comb is located outside the outer lid, it is convenient to clean the comb.
