Pre-Glued False Eyelash Structure for Precise Lash Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing false eyelashes require manual glue application, which is time-consuming and can result in either excessive glue causing discomfort or insufficient glue leading to easy detachment, negatively impacting user experience.
Innovation Solution
A false eyelash pre-applied with glue, featuring eyelash bonding portions designed to attach to real eyelashes from below or above, and a glue pre-application device that accurately applies glue based on eyelash shape and density, ensuring appropriate glue application without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If false eyelashes are applied with glue using conventional methods, then the application process is simple, but the precision and consistency of glue placement are poor leading to messy appearance and potential eye irritation
Solution Approach 1:
The patent applies glue to the false eyelash band before the actual application to the eye. This preliminary gluing action allows for controlled, precise glue placement on the lash band itself, ensuring consistent and accurate positioning without requiring complex real-time application mechanisms.
Solution Approach 2:
The patent introduces a dual-band structure where a first band holds the lashes and a second band applies the glue. This intermediary second band serves as a dedicated glue application mechanism that transfers glue precisely to the first band, improving placement precision while keeping each band's function simple and specialized.
2Manufacturing precision
If glue is applied manually to false eyelashes, then the process is quick, but the consistency and quality of glue distribution are poor
Solution Approach 1:
The patent combines the lash-holding function and glue-application function into a single integrated false eyelash unit with two bands. The first band holds the lashes while the second band applies glue, merging these functions into one pre-assembled product that maintains consistent glue distribution throughout production.
Solution Approach 2:
The glue application is performed in advance during manufacturing rather than at the time of consumer use. This preliminary action allows for controlled, consistent glue distribution across all units during production, eliminating variability while maintaining quick application for the end user.
3Reliability
If conventional false eyelash application is used, then no special equipment is needed, but the result is often messy and may irritate the eyes
Solution Approach 1:
The second band acts as an intermediary glue-application component that ensures reliable and clean glue placement. This dedicated glue band separates the lash-holding function from the glue-application function, improving reliability by ensuring consistent, controlled glue distribution away from the eye area.
Solution Approach 2:
The patent extracts the glue application function into a separate second band distinct from the lash-holding first band. This extraction allows the glue to be applied and controlled independently, improving application reliability by preventing messy contact with the eye while keeping the overall system relatively simple.

AI summary
A false eyelash pre - applied with glue, a glue pre-application device and a method for producing the false eyelash pre-applied with glue. The false eyelash pre-applied with glue comprises a false eyelash body (100) and an eyelash bonding portion; the false eyelash body (100) comprises an eyelash stem (110) and a plurality of false eyelashes (120) connected thereto, the false eyelashes (120) bending toward upper surfaces of the false eyelashes (120); the eyelash bonding portion extends along a length direction of the eyelash stem (110) and is arranged on the upper surfaces of the plurality of false eyelashes (120) near the eyelash stem (110), and the eyelash bonding portion is configured to bond the false eyelash body (100) to a real eyelash from below the real eyelash.
