Mascara Wand Assembly With Interlocking Brush Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mascara wands lack adjustable brush units, which limits the ability to customize the width and arrangement of brush hairs to meet individual user needs, leading to potential shifting of brush units during use, affecting convenience.
Innovation Solution
A mascara wand assembly with multiple disk-like brush units that have notches and blocks forming a 90-degree angle, allowing for secure engagement and separation along the wand, featuring first and second brush hairs that can be arranged spirally and radially, with a cylindrical unit connected to the cap for enhanced positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple brush units are made movable and adjustable along the wand, then the user can collect or separate the brush units to adjust the reach area, but the brush units are not secured properly and may shift during use
Solution Approach 1:
The brush units are designed with movable and adjustable capabilities along the wand, allowing users to collect or separate them to adjust the reach area. This dynamic design enables the brush units to transition between fixed and movable states, resolving the contradiction between adaptability and stability.
Solution Approach 2:
The mascara wand is divided into multiple independent brush units that can be separately adjusted along the wand. Each brush unit can be individually positioned or collected, providing both adjustability and secure engagement through the positioning device.
2Adaptability or versatility
If brush units are made adjustable to meet different user needs, then the customization capability is improved, but the device complexity increases due to the positioning device requirements
Solution Approach 1:
The positioning device is implemented through simple geometric features (notches and blocks) on each brush unit rather than a complex mechanical system. This segmented approach allows each brush unit to be independently positioned while maintaining overall system simplicity.
Solution Approach 2:
The brush units utilize their own structural features (notches and blocks) to achieve positioning and engagement without requiring external positioning mechanisms. This self-service approach reduces device complexity while maintaining customization capability.

AI summary
A mascara wand assembly includes a wand, multiple brush units and a cylindrical brush unit. The wand has a cap and a handle on two ends thereof. The cylindrical brush unit is connected to the cap. The multiple brush units are mounted to the wand and each brush unit has multiple first brush hairs extending radially and outward therefrom. The first brush hairs have different thicknesses. Each first brush hair has multiple sub-brush hairs extending therefrom. Each brush unit has a notch and a block respectively on the top and underside thereof. A 90-degree angle is defined between the notch and block of each brush unit. The block of one brush unit is engaged with the notch of the next brush unit.
