Clamping Makeup Brush Assembly for Glue-Free Head Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional makeup brushes use glue for fixation, leading to environmental unfriendliness, material waste, and inconvenient handle replacement.
Innovation Solution
A glue-free makeup brush design featuring a clamping assembly with a snap-fit connection between the brush head and handle, utilizing clamps and elastic pieces for secure attachment without glue, and a threaded connection for handle replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glue is used for fixing the brush head to the handle, then the brush head is securely fixed, but the assembly is not eco-friendly and handle replacement is inconvenient
Solution Approach 1:
The connection structure is divided into modular components: the handle, the brush head, and an intermediate connecting piece with clamping assembly. This segmentation allows the brush head and handle to be independently replaced without damaging other components, eliminating the need for glue while maintaining secure fixation and enabling easy replacement.
Solution Approach 2:
The patent replaces the chemical bonding method (glue) with a mechanical clamping system. The clamping assembly uses elastic pieces and clamps to provide secure mechanical fixation between the brush head and handle, allowing for easy disassembly and replacement without residue or damage.
2Reliability
If glue is used for fixing the brush head to the handle, then the brush head is securely fixed, but material waste increases due to non-replaceable components
Solution Approach 1:
The design enables the brush head and handle to be separately replaced rather than discarded as an integral unit. When the bristles wear out, only the brush head needs to be replaced while the handle can be reused, significantly reducing material waste. The connecting piece with clamping assembly facilitates this selective replacement.
Solution Approach 2:
By dividing the makeup brush into separable components (handle, connecting piece, brush head) with standardized interfaces, the patent enables selective replacement of worn parts. This segmentation transforms the traditional disposable integral design into a sustainable system where only necessary components are replaced.
3Device complexity
If an integral design is used for the makeup brush, then the structure is simple, but the brush must be discarded when bristles wear out
Solution Approach 1:
The patent introduces a modular segmented design with standardized connecting pieces and clamping assemblies. While slightly more complex than an integral design, this segmentation enables selective replacement of the brush head without discarding the handle, reducing overall material waste while maintaining reasonable structural simplicity.
Solution Approach 2:
The connecting piece with clamping assembly serves as a universal interface that can accommodate different brush head configurations. This universality allows the same handle to work with multiple brush heads, reducing the need to discard and replace entire brush assemblies and thereby reducing material waste.

AI summary
A novel glue-free makeup brush with a clamping assembly, including a handle, a brush head, and a connecting piece. The brush head includes bristles and a mounting piece, and is arranged on an upper end of the handle. The bristles are arranged on the mounting piece, and the mounting piece is clamped with the connecting piece. An upper end of the clamping assembly, formed by a first clamp and a second clamp, is provided with a groove, in which the mounting piece is arranged. In this way, the brush head can be arranged on the clamping assembly without using glue. The handle is removably connected with a sleeve of the connecting piece.
