Modular Brush With Magnetic Bristle Retraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brushes for makeup or art are cumbersome due to their large volume and weight, making them inconvenient to carry and use, and lack easy interchangeability of brush heads.
Innovation Solution
A modular brush design where brush heads stored in a handle compartment are automatically exposed and retracted using a magnetic mechanism, allowing easy interchange and protection of bristles when not in use, reducing the overall volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple brushes are carried in a set, then various makeup functions are available, but the volume and weight increase making portability inconvenient
Solution Approach 1:
The brush system is divided into separate components: a handle and interchangeable brush heads. The handle contains a compartment that can store multiple brush heads, while only one brush head is exposed at a time for use. This segmentation allows multiple brush functions to be available without requiring all brushes to be simultaneously exposed, thereby reducing the effective volume and weight during carrying.
Solution Approach 2:
Multiple brush heads are stored inside the handle compartment, with each brush head nested within the handle structure. The brush heads can be retracted into the handle when not in use, similar to nested dolls. This nesting arrangement allows multiple brush heads to occupy minimal space when not actively being used, significantly reducing the volume occupied by the brush set during portability.
2Stability of the object's composition
If brush heads are fixed to the handle, then structural stability is maintained, but interchangeability of brush heads becomes difficult
Solution Approach 1:
The connection between the handle and brush heads is made dynamic rather than fixed. The brush heads can be easily attached to and detached from the handle through a simple coupling mechanism. The mounting portion within the compartment can rotate or pivot to facilitate the attachment and detachment operations, providing both stability during use and ease of interchangeability when needed.
3Ease of operation
If bristles are exposed outside the brush head, then brush functionality is enabled, but bristles are vulnerable to damage when not in use
Solution Approach 1:
The bristles are extracted from the exposed position and retracted into the brush head ferrule when not in use. The brush head can be completely inserted into the handle compartment, with the bristles withdrawn from the external environment. This extraction of bristles from the vulnerable exposed position protects them from damage, dust, and contamination while maintaining full brush functionality when the brush head is mounted and exposed for use.
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
Enables easy interchange of brush heads and protects bristles when not in use, significantly reducing the volume and weight of the brush, enhancing portability and convenience.
Implementation Method 1
Through operation of the moving magnetic body and fixed magnetic body in a brush head, the bristles retract into and are protected inside of the brush head
Implementation Method 2
The rack gear (25) or teeth (25a) is or are installed at the end of the cover (20), and when the end of the cover (20) moves adjacent to the mounting portion (40) during the cover (20) opening operation, the rack gear (25) aligns with and pivots the pinion gear (45), or the teeth (25a) align with pivot the wheel (45a)

AI summary
The present invention relates to a modular brush, with improved structure so that modular brush heads of various grades stored inside the storage compartment in the handle, are automatically exposed outwardly from the storage compartment, in connection with the cover opening movement. Thus, anybody can easily interchange one modular brush head with another. In particular, the modular brush is comprised mainly of a handle (10), cover (20), brush head portions (30), mounting portions (40), and lifting portions (50), so that by simple operation, the brush bristles in a gathered state retract into the ferrule tube of the brushhead for protection when not in use.
