Mascara Brush With Segmented Filaments In Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mascara brushes face challenges in evenly applying mascara liquid, maintaining a combing function to prevent eyelash sticking, and efficiently forming irregular brush shapes, which results in reduced brushing effectiveness and increased manufacturing costs.
Innovation Solution
A mascara brush design featuring a brush rod with slots of varying lengths, into which filaments formed in specific patterns are inserted and adhered using adhesives or fusion techniques, allowing for the creation of various brush patterns and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mascara brushes are manufactured with long bristles and irregularly arranged bristles, then the brush structure is simple, but the brushing function is insufficient causing mascara liquid aggregation
Solution Approach 1:
The brush is divided into multiple rows of filaments with different lengths arranged in a structured pattern. Instead of using uniformly long or irregular bristles, the invention segments the brush into functional zones with short, medium, and long filaments organized in alternating rows, creating a comb-like structure that prevents aggregation while maintaining structural organization
Solution Approach 2:
Different regions of the brush have different filament lengths to perform different functions. The invention uses short filaments for combing and separating eyelashes, medium filaments for applying mascara, and long filaments for reaching the lash roots, with each region optimized for its specific function rather than using uniform bristles throughout
2Adaptability or versatility
If irregular form of brush is created by assembling and manufacturing a plurality of brushes, then the brush shape is diverse, but manufacturing cost becomes expensive
Solution Approach 1:
The filaments are pre-arranged in a specific irregular pattern on a carrier before being attached to the brush handle. This preliminary arrangement allows the complex irregular shape to be created in one manufacturing step rather than by assembling multiple separate brush components, reducing manufacturing complexity and cost while maintaining shape diversity
3Ease of operation
If mascara liquid is applied using conventional brushes, then the application process is simple, but the mascara liquid aggregates at any part reducing aesthetic sense
Solution Approach 1:
The brush filaments are segmented into different length categories (short, medium, long) arranged in alternating rows, creating a comb-like structure that physically separates and distributes mascara liquid evenly across the eyelashes during application, preventing aggregation while maintaining ease of use
Solution Approach 2:
The multi-length filament structure creates dynamic spacing between bristles that adapts during application. The varying lengths create gaps that allow mascara to flow through and distribute evenly, while the combing action of shorter filaments continuously separates lashes to prevent clumping during the brushing motion
