Rotating Brush Head Cosmetic Tool with Axial Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic tools require manual dipping of the brush head into cosmetic substances, which is complicated and inconvenient, especially in terms of portability and ease of use.
Innovation Solution
A cosmetic tool featuring a brush head, a material core with a discharge port, a moving sleeve, a fixed sleeve, and a transmission structure that allows the brush head to automatically dip into the cosmetic substance by rotating through the transmission mechanism when the moving sleeve is axially moved.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual dipping of brush head is used, then structure remains simple, but operation becomes complicated and inconvenient
Solution Approach 1:
The brush head is designed to be rotatable relative to the moving sleeve, transforming from a static component to a dynamic one. This rotational capability enables automatic dipping into cosmetic substances without manual intervention, significantly improving ease of operation while maintaining reasonable structural complexity through the integration of rotation mechanisms
Solution Approach 2:
The cosmetic tool is designed to perform the dipping action automatically through the coordinated movement of the moving sleeve and rotatable brush head. The system serves itself by using the user's simple insertion motion to automatically position and rotate the brush head into the cosmetic substance, eliminating the need for manual dipping operations
2Ease of operation
If brush head and material core are separate, then ease of cleaning is improved, but portability deteriorates
Solution Approach 1:
The brush head is nested within the moving sleeve structure, with the brush head holder positioned inside the moving sleeve body. This nested arrangement integrates multiple functional components into a compact unified structure, significantly improving portability while maintaining separate brush head sections that can be easily removed for cleaning
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
The tool simplifies the makeup process by allowing automatic dipping of the brush head into the cosmetic substance, making the operation straightforward and convenient, while also integrating the material core and brush head for improved portability.
Implementation Method 1
the transmission structure includes a transmission mechanism through which the fixed sleeve, the moving sleeve and the brush head are connected; wherein, when the moving sleeve moves along the axial direction, the moving sleeve drives the brush head to turn over through the transmission mechanism

AI summary
A cosmetic tool comprises a brush head (10), a material core (20), a movable sleeve (30), a fixed sleeve (40), and a transmission structure. The material core (20) is mounted in the movable sleeve (30), the brush head (10) is located at one end of the movable sleeve (30) and is arranged opposite the material core (20), and a discharge port is formed in an end face of the material core (20) facing the brush head (10). The fixed sleeve (40) is sleeved outside the movable sleeve (30), and the movable sleeve (30) can move along an axial direction. The fixed sleeve (40), the movable sleeve (30) and the brush head (10) are connected by means of a transmission structure, and when the movable sleeve (30) moves along the axial direction, the movable sleeve (30) drives the brush head (10) to turn over by means of the transmission structure, so as to dip in a cosmetic substance at the discharge port. The cosmetic substance of the cosmetic tool has a simple dipping operation. In addition, the material core and the brush head are integrated into one component, which is convenient to carry.
