Angled Mascara Bristle Structure for Easier Eyelash Combing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mascara brushes require repeated dipping in material, leading to poor adhesion, residue, and difficulty in combing eyelashes due to perpendicular bristles.
Innovation Solution
A mascara brush with tornado-shaped bristles that intersect non-perpendicularly with the core, featuring varying angles and twisted structures for improved insertion and application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bristles are arranged perpendicularly to the core axis, then the brush structure is simple and easy to manufacture, but the bristles cannot be easily inserted between eyelashes and comb them effectively
Solution Approach 1:
The bristle arrangement transitions from symmetric perpendicular orientation to asymmetric angled orientation. The bristles are arranged at an angle of 0-45 degrees relative to the core axis, creating an asymmetric configuration that enables easier insertion between eyelashes while maintaining manufacturing feasibility through standardized angular parameters.
Solution Approach 2:
The bristle arrangement moves from a two-dimensional perpendicular configuration to a three-dimensional angled configuration. By introducing an angular dimension (0-45 degrees from the axis), the bristles gain the ability to penetrate and comb eyelashes more effectively while the core structure remains simple.
2Productivity
If bristles are arranged perpendicularly to the core axis, then the brush cross-section is larger, but the material loading capacity is insufficient requiring repeated dipping
Solution Approach 1:
The bristle arrangement parameter changes from perpendicular (90 degrees) to angled (0-45 degrees) orientation. This parameter change optimizes the bristle configuration for better material loading and application efficiency, allowing sufficient material capacity without increasing the brush cross-section.
3Reliability
If bristles are arranged perpendicularly to the core axis, then the brush structure is compact, but residue remains on the bristles after use
Solution Approach 1:
The asymmetric angled bristle arrangement (0-45 degrees) creates a configuration that facilitates complete material transfer to eyelashes, eliminating residue on the bristles. The angular orientation allows for better material distribution and adhesion compared to the symmetric perpendicular arrangement.

AI summary
A mascara brush having a tornado-shaped bristle includes a bristle and a core. A root of the bristle is provided on the core, and a free end of the bristle is provided away from the core. There is at least one bristle. A centerline of the bristle intersects with an axis of the core in a non-perpendicular manner. By providing an included angle between the centerline of the bristle and the axis of the core, the bristle is inserted between eyelashes more easily. As the bristle is not perpendicular to the axis of the core, a cross section of the whole mascara brush is reduced. While the length of the bristle remains the same, the opening of a mascara bottle is reduced. The new mascara brush has the advantages of better application effect, more compact structure and better ease of eyelash combing.
