Segmented Eyelash Clusters for Natural Gradient Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for enhancing eyelashes, such as mascara and false eyelashes, are either temporary, messy, time-consuming, and can damage natural lashes, while professional applications are labor-intensive and may not achieve a natural look.
Innovation Solution
A method of sectioning the eyelid into zones and applying extension lashes of varying lengths to create a more natural and attractive appearance, using a ring with a container for adhesive and forceps to precisely attach lashes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If mascara is applied to enhance eyelashes, then eyelashes can be darkened and lengthened, but the effect is temporary and requires frequent reapplication
Solution Approach 1:
The false eyelash strip is divided into multiple individual lash clusters, each containing a specific number of lashes. This segmentation allows for selective application to different zones of the eyelid, enabling longer-lasting enhancement without requiring full reapplication, as unused clusters can be saved for touch-ups.
2Ease of manufacture
If false eyelash strip is applied to enhance appearance, then eyelashes can be enhanced, but the application process is messy due to excess adhesive scattering
Solution Approach 1:
The adhesive application process is extracted and minimized to only the necessary areas. Each lash cluster is pre-coated with adhesive only at the base, and application is done zone-by-zone rather than applying adhesive to the entire strip at once, preventing excess adhesive from scattering.
Solution Approach 2:
Adhesive is applied preliminarily and sparsely to the base of each lash cluster before application, rather than applying大量 adhesive to the entire strip. This preliminary, minimal adhesive application prevents scattering while ensuring adequate bonding.
3Ease of manufacture
If full cluster of synthetic eyelashes is applied to enhance eyelashes, then appearance is enhanced, but eyes feel heavy and tired
Solution Approach 1:
The full cluster of synthetic eyelashes is segmented into multiple smaller lash clusters distributed across the eyelid. This segmentation reduces the concentrated weight on any single area, distributing the load more evenly and reducing the feeling of heaviness and fatigue.
Solution Approach 2:
Different zones of the eyelid receive different densities and types of lash clusters. The inner zone receives lighter, sparser clusters while the outer zone can handle slightly heavier clusters, creating a natural gradient that reduces overall weight perception while maintaining enhancement.
4Manufacturing precision
If individual lashes are glued one by one to achieve natural look, then appearance is enhanced, but the process is time consuming taking an hour or more
Solution Approach 1:
Lashes are pre-grouped into small clusters of 2-5 individual lashes, which are then applied as units rather than one by one. This segmentation maintains the natural, precise look of individual lashes while dramatically increasing application speed by applying multiple lashes simultaneously in each cluster.
Solution Approach 2:
Multiple individual lashes are merged into small clusters that function as a single application unit. This combining approach preserves the precision and natural appearance of individual lash application while achieving the productivity of applying multiple lashes at once.
5Ease of operation
If extension lashes of uniform length are applied to all zones, then application is simplified, but the look appears artificial and stiff
Solution Approach 1:
Different zones of the eyelid are assigned different lash lengths and densities to create a natural gradient. The inner zone receives shorter, lighter clusters while the outer zone receives progressively longer and slightly fuller clusters, mimicking the natural lash growth pattern and eliminating the artificial, uniform appearance.
Solution Approach 2:
Instead of symmetric, uniform lash length across all zones, the design employs asymmetric length progression from inner to outer zones. This asymmetry creates a more natural, dynamic appearance that follows the natural contours and growth patterns of eyelashes.

AI summary
A method of sectioning eyelashes into zones is disclosed. A method of sectioning eyelashes into zones comprises dividing a surface of an eyelid into zones and applying extension lashes to natural lashes within the zones. Zones can comprise an inner zone, a mid-zone and an outer zone. Furthermore, at least a portion of extension lashes within inner zone can have a first length, while the extension lashes within middle zone and outer zone can have a second and third length, respectively.
