Eyelash Fiber Support Device with Water-Based Adhesive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyelash extensions and false lashes are not user-friendly, time-consuming to apply, difficult to remove, and pose safety and hygiene concerns due to the use of cyano-acrylate glues, requiring professional application and lasting for an extended period.
Innovation Solution
A cosmetic assembly and method using an adhesive composition applied to natural eyelashes with a support device holding fibers, allowing easy and quick attachment and removal of false eyelashes for a perceivable volume, lengthening, and curling effect, without the need for tweezers and minimizing skin contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional false eyelashes are used with cyano-acrylate glue, then strong adhesion is achieved, but safety and hygiene are compromised
Solution Approach 1:
The patent changes the chemical parameters of the adhesive by replacing cyano-acrylate glue with a water-based adhesive composition containing polyvinyl alcohol and carboxymethyl cellulose. This substitution maintains adhesion functionality while eliminating the harmful effects of cyano-acrylate, thereby improving safety and hygiene without sacrificing bonding strength
Solution Approach 2:
The patent employs a disposable support structure that holds the fibers and is discarded after single use. This eliminates the need for removing and reusing adhesive-containing components, ensuring hygiene by preventing residual glue contamination and simplifying the application process for consumers
2Reliability
If individual fiber application method is used, then natural finish is achieved, but application time and complexity increase
Solution Approach 1:
The patent merges multiple individual fibers onto a single support structure, allowing them to be applied simultaneously to the eyelash line. This combines the natural finish quality of individual fiber application with the efficiency of batch processing, reducing application time from hours to minutes while maintaining aesthetic quality
Solution Approach 2:
The fibers are pre-positioned and pre-bonded to the support structure before application to the consumer. This preliminary arrangement ensures proper spacing, alignment, and orientation of fibers, enabling rapid application without requiring precise manual placement of each fiber during the actual eyelash application process
3Reliability
If professional application service is used, then proper application is ensured, but cost and accessibility increase
Solution Approach 1:
The patent designs a self-service system where consumers can apply the fiber lashes themselves using the provided support structure and adhesive composition. The intuitive design of the support and the simplified application process enable non-professionals to achieve proper application quality at home, eliminating the need for expensive professional services and increasing accessibility
Solution Approach 2:
The support structure serves as an intermediary tool that bridges the gap between professional and amateur application. It provides the precision, control, and guidance normally supplied by a professional technician, enabling consumers to achieve reliable application results without requiring specialized training or expertise
