Solution Overview
Problem
Existing artificial eyelash extension methods require professional application, are time-consuming, and cause discomfort due to differential lash growth rates, leading to premature detachment and maintenance issues.
Innovation Solution
A method and apparatus using pre-formed segments of artificial eyelash fibers embedded in a substrate, adhered to natural lashes with a rheological adhesive, allowing for easy application and accommodation of differential lash growth rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If individual fibers are applied to individual natural lashes using highly reactive adhesives, then the extensions provide semi-permanent results lasting about three weeks, but the application process takes two to three hours and requires professional technicians
Solution Approach 1:
The patent divides the artificial eyelash extension into multiple segments (first segment and second segment) that can be applied separately to different portions of the natural lash. This segmentation allows for faster application while maintaining the semi-permanent duration, as each segment can be quickly positioned and bonded without requiring the time-consuming individual fiber application process
Solution Approach 2:
The patent applies a first adhesive to the first segment and allows it to become tacky before applying the segment to the natural lash. This preliminary action of pre-adhering the segment reduces the overall application time while ensuring proper bonding, eliminating the need for lengthy preparation steps during the actual application process
2Duration of action of stationary object
If individual fibers are applied to individual natural lashes, then semi-permanent extensions are achieved, but the process requires highly trained technicians and safety precautions that increase cost
Solution Approach 1:
By dividing the extension into segments that can be applied to different portions of the natural lash, the patent simplifies the application process. Each segment can be independently positioned and bonded, making the process more manageable and less prone to error, thereby reducing the need for highly trained technicians while maintaining semi-permanent results
Solution Approach 2:
The preliminary application of adhesive to the first segment and allowing it to become tacky creates a user-friendly process that is easier to perform. This pre-prepared state reduces the skill level required for proper application, enabling less trained individuals to achieve consistent results without compromising the semi-permanent duration
3Ease of operation
If artificial eyelashes are applied as groups or strips with temporary adhesive, then consumers can apply them themselves in about 20 minutes, but they are difficult to apply, uncomfortable, and come off prematurely with moisture
Solution Approach 1:
The patent divides the artificial eyelash extension into multiple segments that can be applied separately to different portions of the natural lash. This segmentation enables consumers to easily position and apply each segment individually while achieving reliable, long-lasting adhesion that resists moisture, unlike traditional strip applications
Solution Approach 2:
The patent changes the adhesive parameter from temporary adhesive used in strip applications to a more durable adhesive system that provides semi-permanent bonding. This parameter change allows the extension to remain affixed for about three weeks while still enabling consumer self-application, resolving the contradiction between ease of application and adhesion durability
4Loss of time
If segments of artificial eyelash fibers are embedded in a substrate and adhered with rheological adhesive, then quick self-application is enabled with multi-day wear, but the accommodation of differential lash growth rates must be achieved
Solution Approach 1:
The patent divides the extension into segments that can be applied to different portions of the natural lash, allowing each segment to move independently with the natural growth rate of that specific area. This segmentation enables quick self-application while accommodating differential growth rates across the lash line
Solution Approach 2:
The patent employs a rheological adhesive that changes its properties under stress, allowing it to be applied quickly and then adapt to the dynamic growth of natural lashes. This dynamic characteristic enables the adhesive to accommodate differential growth rates while maintaining strong bonding, resolving the contradiction between fast application and growth accommodation

AI summary
In one embodiment, a method for manufacturing an artificial eyelash includes configuring a placement mark on a surface, positioning a plurality of fibers on the surface based on the placement mark, placing a first adhesive near a base of the plurality of fibers to secure the plurality of fibers together, placing a second adhesive near the base of the plurality of fibers, and cutting the plurality of fibers in accordance to a predetermined shape. In particular, the second adhesive is a pressure-sensitive adhesive.
