Modular Eyelash Subassemblies for Custom Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyelash adornments, such as unitary, individual, and corner lashes, often fail to match the curvature and length of the wearer's lash line, leading to distortion, inadequate adhesion, and unnatural appearance, posing challenges in fitting and health safety concerns.
Innovation Solution
An eyelash adornment apparatus comprising a plurality of lash subassemblies with elongated mounting portions and filaments, allowing for customizable attachment to the eyelid to provide varying visual impressions and effects, accommodating individual eye shapes and characteristics through interchangeable and adaptable subassemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If unitary lashes with a single mounting portion are used, then ease of application is improved, but the ability to match the curvature and length of the wearer's lash line deteriorates
Solution Approach 1:
The false eyelash is divided into multiple modular segments (first false eyelash segment, second false eyelash segment, etc.), each with its own mounting portion. These segments can be independently selected and applied to different portions of the lash line, allowing customization to match the wearer's specific eye shape, lash line curvature, and length requirements while maintaining relatively simple application procedures.
2Adaptability or versatility
If individual lashes are applied one-by-one, then the ability to match the lash line is improved, but the difficulty of application and time required deteriorates
Solution Approach 1:
Instead of applying individual lashes one-by-one, the invention groups lashes into modular segments that contain multiple lash filaments arranged together. Each segment can be applied as a unit, significantly reducing the number of separate application steps while still allowing customization to match the lash line. This maintains adaptability while reducing application complexity and time.
3Ease of operation
If corner lashes with a specific shape are used, then ease of application is improved, but the ability to integrate with natural lash filaments and blend in deteriorates
Solution Approach 1:
The modular segments are designed with varying local characteristics - different mounting portion lengths, curvatures, and lash filament arrangements in different segments. This allows each segment to be optimized for its specific location on the lash line, ensuring proper integration and blending with natural lashes at each position while maintaining overall ease of application through the modular system.

AI summary
A method of adorning an eyelash of a wearer (the wearer having an eyelid with a natural lash line containing natural eyelashes) includes providing at least first and second lash subassemblies. Each lash subassembly includes an elongated mounting portion and a plurality of elongated lash filaments. Each lash filament has a filament base and an oppositely disposed filament tip. The filament base is attached to the mounting portion with the filament tip extending from the mounting portion. The first and second lash subassemblies are concurrently affixed to the eyelid. When concurrently affixed to the eyelid, the first and second lash subassemblies collectively provide a different appearance of the plurality of elongated lash filaments of the first lash subassembly than an appearance collectively provided by the plurality of elongated lash filaments of the second lash subassembly.
