Eyelash Isolation Hook Structure for Precise Lash Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyelash-handling tools require multiple devices for isolating and holding lashes during eyelash extension or cosmetic application, leading to hand fatigue and inconsistent alignment.
Innovation Solution
The eyelash isolation tool features paired lash hooks or a spreader body with extension bars that maintain consistent lash isolation without requiring sustained gripping force, improving visibility and alignment precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple conventional tools are used for isolating and holding lashes, then lash isolation can be achieved, but hand fatigue increases and alignment consistency deteriorates
Solution Approach 1:
The patent combines multiple conventional tools (lash isolation tool and lash holding tool) into a single integrated eyelash extension tool. The tool features a body with a first engagement feature for isolating lashes and a second engagement feature for holding lashes, allowing both functions to be performed with one tool, thereby reducing hand fatigue and improving alignment consistency.
Solution Approach 2:
The eyelash extension tool is designed with multi-functionality, serving both as a lash isolation tool and a lash holding tool simultaneously. The first engagement feature (isolation arm) and second engagement feature (holding arm) work together to provide comprehensive lash management in a single device, eliminating the need to switch between multiple specialized tools.
2Adaptability or versatility
If multiple devices are used for lash isolation and holding, then comprehensive lash control is achieved, but device complexity increases
Solution Approach 1:
The patent merges the functionality of separate lash isolation and holding devices into a single integrated tool. The body of the tool incorporates both the first engagement feature (isolation arm with tip) and second engagement feature (holding arm with tip), providing comprehensive lash control while reducing the number of devices from two to one.
3Stability of the object's composition
If conventional gripping tools are used to hold lashes, then lash positioning is achieved, but hand fatigue increases due to sustained gripping force
Solution Approach 1:
The holding arm of the tool is designed to automatically adjust and maintain lash positioning without requiring sustained gripping force from the operator. The mechanical design of the second engagement feature allows the tool to self-maintain the held position, reducing the physical effort needed to keep lashes stable during the extension process.

AI summary
An eyelash isolation tool having a body extending between a first lash-engaging member and a second lash-engaging member. The body comprises the first lash-engaging member at one end and the second lash-engaging member at another end. The first lash-engaging member and second lash-engaging member each configured to engage a set of eyelashes. The first lash-engaging member and second lash-engaging member positioned relative to one another to define a lash-isolation region for separating a controlled portion of the set of eyelashes from a working portion.
