Solution Overview

Problem

Conventional eyelash extensions require individual application to prevent sticking, making the process time-consuming and costly, while false eyelashes can be uncomfortable and easily distinguishable from natural lashes.

Innovation Solution

Clusters of artificial lash extensions are formed by fusing multiple artificial hairs together using a hot melt method, allowing them to be applied in a single motion along the upper tightline, and secured to the underside of natural lashes using an adhesive.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If individual eyelash extensions are applied one by one to prevent sticking, then the eyelash extensions can be securely attached, but the application process becomes time-consuming and costly

Engineering Contradiction:
Improveattachment securityVSAvoidapplication time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Multiple individual eyelash extensions are merged into a single cluster unit containing multiple lashes. This cluster can be applied as one piece to multiple natural lashes simultaneously, maintaining secure attachment while dramatically reducing application time and cost.

Inventive Principle:
Principle #5Merging (Combining)

2Stability of the object's composition

If clusters of artificial lashes are applied individually to avoid sticking, then even distribution is achieved, but the application process remains time-consuming

Engineering Contradiction:
Improveeven distributionVSAvoidapplication time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

Multiple cluster units are merged into a single applicator assembly that can be applied simultaneously to multiple locations along the lash line. This maintains even distribution across the eyelid while reducing the number of separate application steps.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If false eyelashes are applied as strips to the eyelid, then application is fast and simple, but they are easily distinguishable from natural lashes and uncomfortable

Engineering Contradiction:
Improveapplication speedVSAvoidcomfort and natural appearance
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The false lash strip is segmented into multiple individual cluster units that can be selectively applied to specific areas of the natural lashes. This segmentation allows for a more natural, graduated appearance that blends seamlessly with natural lashes while maintaining fast application through the cluster design.

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This method reduces application time, lowers costs, and provides a seamless blend with natural lashes, as the lash fusions can be applied uniformly and securely in a single motion.

Implementation Method 1

Clusters of artificial lashes include multiple artificial hairs that are heated and then secured to one another

AI summary

A kit includes an adhesive and artificial lash extensions. Each of the artificial lash extensions includes a knotless base and groupings of artificial hairs. The groupings protrude from the knotless base along a length of the knotless base. The knotless bases are designed to attach to an underside of natural eyelashes using the adhesive. The kit includes an applicator having a pair of opposing arms. Each arm includes a first section and a second section connected to the first section of the arm. The second sections include a curvature. At least part of the second sections are designed to grasp an artificial lash extension of the artificial lash extensions.
