Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing artificial 3-dimensional eyelashes do not fully address the need for creating realistic, customizable, and comfortable false eyelashes that mimic natural eyelashes effectively.
Innovation Solution
A method involving the selection of materials such as latex, silicone, or rubber to achieve desired thickness, sculpting existing eyelashes or creating them from scratch, and using molds made of plaster, silicone, or metal to cast finished 3-D eyelashes, which can include natural objects or digital designs printed using 3-D printers, to achieve a realistic and customizable shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional artificial eyelashes are manufactured using flat or simple curved bases, then the manufacturing process is simple and cost-effective, but the eyelashes fail to mimic the natural 3-dimensional structure of real eyelashes, reducing realism and aesthetic appeal
Solution Approach 1:
The patent transitions from traditional 2-dimensional flat or simple curved eyelash bases to 3-dimensional structures that mimic natural eyelash curvature and volume. The base is formed with varying heights and depths to create realistic eyelash contours, and individual eyelashes are positioned at different angles and depths to achieve a natural 3-dimensional appearance that enhances aesthetic appeal while maintaining manufacturability through mold-based processes.
2Quantity of substance
If existing eyelashes are coated with material to achieve desired thickness, then volume and aesthetic appeal are enhanced, but the manufacturing process becomes more complex and time-consuming
Solution Approach 1:
The patent incorporates the desired eyelash thickness and volume directly into the base structure during the molding process, rather than requiring subsequent coating steps. The base is pre-formed with varying thickness zones that correspond to different eyelash density requirements, and eyelashes are positioned during assembly to achieve the desired volume. This preliminary structuring eliminates time-consuming coating operations while maintaining the ability to create varied thickness patterns.
3Manufacturing precision
If molds are used to cast finished 3-D eyelashes, then manufacturing precision and consistency are improved, but the initial mold creation process becomes more complex
Solution Approach 1:
The patent uses physical templates or digital 3-D modeling to create accurate mold cavities that replicate the desired eyelash structure. The mold design incorporates the target eyelash curvature, thickness distribution, and positioning features directly into the cavity geometry. This copying approach allows for precise reproduction of the desired eyelash form across multiple units while the mold itself remains a straightforward casting tool, reducing the perceived complexity despite the precision achieved.
4Adaptability or versatility
If natural objects or digital designs are used as templates for eyelash creation, then customization and realism are enhanced, but the manufacturing process becomes more complex
Solution Approach 1:
The patent employs physical templates derived from natural eyelash samples or digital 3-D models to create mold cavities that replicate specific eyelash styles and characteristics. These templates can be customized to match different eyelash preferences, natural variations, or artistic designs. The template-based approach allows for easy modification of the mold design to achieve different styles while maintaining a consistent manufacturing process, thereby enabling customization without proportionally increasing process complexity.
