Reversible makeup brush holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional makeup brush holders have a fixed structure, leading to water retention in the brushes, potential bacterial growth, and risk of brush deformation, along with a complex and costly design that complicates assembly and cleaning.
Innovation Solution
A reversible makeup brush holder with a rotatable insertion seat and a concave base that allows water to drip off, featuring a support post and an elastic sheet to hold the brush handle, enabling 180-degree rotation to face the bristles downwards for drying and 360-degree horizontal rotation for easy brush selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the makeup brush holder uses a fixed structure with brushes placed bristles up, then the holder structure is simple, but water remains in the bristles causing bacterial growth and brush deformation
Solution Approach 1:
The patent applies the dynamics principle by making the insertion seat rotatable rather than fixed. The insertion seat can rotate 180 degrees around the support post, allowing users to switch between storing brushes in upright position (for use) and inverted position (for drying). This dynamic transformation enables the same structure to serve multiple functions: preventing water accumulation when inverted and ensuring easy access when upright, thereby resolving the contradiction between brush durability and structure complexity.
2Ease of operation
If the holder allows 360-degree rotation for brush selection, then brush accessibility is improved, but the structure becomes more complex and costly
Solution Approach 1:
The patent implements a rotatable insertion seat that can rotate horizontally 360 degrees around the support post, enabling users to access any brush position with ease. The rotation mechanism is simplified by using a central support post with the insertion seat mounted on it, allowing free rotation without complex gears or motors. This dynamic design achieves high ease of operation while maintaining relatively simple structure.
3Reliability
If residual water is not discharged from bristles, then the holder structure remains simple, but bacteria breed and brushes deform
Solution Approach 1:
The patent uses the dynamics principle by enabling the insertion seat to rotate 180 degrees, allowing brushes to be stored in an inverted position where bristles point downward. This simple positional change utilizes gravity to naturally drain water from the bristles, eliminating the need for complex drying mechanisms such as heating elements, fans, or absorbent materials. The same rotatable structure that provides functional versatility also solves the water discharge problem.
4Object-affected harmful factors
If the base does not have water receiving capability, then the holder structure is simpler, but water stains the tabletop
Solution Approach 1:
The patent applies the self-service principle by designing the base with a concave bottom that automatically collects and retains water dripping from inverted brushes. The concave structure acts as an integrated water reservoir, eliminating the need for separate drainage systems, pumps, or external containers. The base structure serves dual purposes: supporting the rotatable insertion seat and collecting excess water, thereby preventing tabletop staining without adding significant complexity.
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 solution prevents water retention, reduces bacterial growth, prolongs brush life, simplifies assembly and cleaning, and arranges insertion holes in a staggered manner for unobstructed access to brushes, lowering production costs and preventing tabletop stains.
Implementation Method 1
The elastic sheet is formed with insertion slots for insertion of makeup brushes
Implementation Method 2
the base has a base body for receiving water... a concave base body for the water remaining in the bristles of the makeup brush to flow to the base body

AI summary
A reversible makeup brush holder includes a base body for receiving water. The middle of the base body is connected with a support part. The insertion seat includes a disc body having an accommodation hole. Upper and lower surfaces of the disc body are provided with a rotary shaft, respectively. The rotary shaft is pivoted to the support part. Through the aforesaid design, a makeup brush can be inserted into the insertion hole. The insertion seat can be lifted and overturned, so that the water remaining in the bristles of the makeup brush can drip down rapidly on the base body. The user can clean the makeup brush holder conveniently.
