Lash Extension Applicator and Case for Single-Motion Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyelash extension application is time-consuming and requires skilled professionals due to the need for individual attachment of each lash extension to avoid clumping, while false eyelashes are easily distinguishable and uncomfortable for extended wear.
Innovation Solution
Introduces cases for housing sets of artificial lash extensions with multiple lash fusions and applicators with concave-shaped arms to grasp and apply the entire set to the natural lashes in a single motion, using adhesive for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual lash extensions are applied one by one to avoid clumping, then the eyelash extensions do not stick together, but the application process becomes time-consuming and requires skilled professionals
Solution Approach 1:
Multiple separate lash extensions are merged into a single integrated strip structure, allowing them to be applied together as one unit rather than individually, thus reducing application time while maintaining the non-clumping benefit through pre-spaced positioning
Solution Approach 2:
The lash extensions are pre-arranged and pre-positioned on the strip before application, so that when applied, they are already in their correct positions and orientations, eliminating the need for individual placement and reducing application time
2Productivity
If false eyelashes are applied as strips to cover the entire eyelid, then application is quick and easy, but they are easily distinguishable from natural lashes and uncomfortable for extended wear
Solution Approach 1:
The false eyelash strip is segmented into multiple discrete lash extensions positioned along the strip, allowing light and vision to pass through the spaces between them, making them less distinguishable from natural lashes while maintaining quick strip application
Solution Approach 2:
Different portions of the strip have locally optimized properties - the strip structure enables quick application while the spaced individual lashes in specific positions provide natural appearance and comfort by allowing light penetration and avoiding complete eyelid coverage
3Manufacturing precision
If clusters of artificial lashes are applied individually to ensure even distribution, then multiple clusters are evenly distributed across the lash line, but the application process is time-consuming
Solution Approach 1:
Multiple lash clusters are merged into a single strip structure with pre-determined spacing, maintaining the even distribution benefit while allowing simultaneous application of all clusters, thus reducing application time
Solution Approach 2:
The even distribution of lash clusters along the strip is established in advance during manufacturing, so that when the strip is applied, the clusters are already positioned for even distribution across the lash line, eliminating the need for individual positioning

AI summary
A kit includes artificial lash extensions. Each of the artificial lash extensions includes groupings of artificial hairs and a knotless base. The groupings protrude from the knotless base along a length of the base. The knotless bases of the artificial lash extensions attach to an underside of natural eyelashes in an arrangement adjacent to one another. The kit also includes an applicator having a pair of opposing arms that are joined to each other at a proximal end of each arm. Each arm includes a first section having the proximal end of the arm and a second section connected to the first section of the arm. The second section includes a first end portion, a second end portion, and a curvature disposed between the first end portion and the second end portion.
