Spring-Clamp Eyelash Applicator for Precise Passive Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic applicators struggle to apply false eyelashes and fibers efficiently, lacking ergonomic design and precise control over clamping forces, which complicates the application process.
Innovation Solution
The use of spring-backed clamping discs and mechanical energy store assemblies in applicators that provide compressive clamping forces for holding and releasing false eyelashes, combined with ergonomic features for precise motor movements and adjustable gestures, allowing for easy application of lashes and fibers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual pressure is applied to hold false eyelashes, then the lashes can be positioned, but the application process becomes difficult and imprecise
Solution Approach 1:
The spring mechanism automatically applies and releases clamping force without requiring manual pressure from the user. The spring-backed clamping disc holds the false eyelash passively through elastic force, and releases it automatically when activated, making the applicator self-regulating and eliminating the need for user force control.
Solution Approach 2:
The applicator transitions from a static holding mechanism to a dynamic spring-based system that can adjust its clamping force. The spring allows the applicator to move between a closed clamping state and an open releasing state, providing controlled motion and precise positioning capability.
2Ease of operation
If a simple applicator design is used, then the device is easy to manufacture, but it lacks ergonomic features and precise control
Solution Approach 1:
The applicator is divided into distinct functional components: a spring mechanism, a clamping disc, a shaft, and a handle. This segmentation allows each component to be optimized for its specific function (clamping, positioning, manipulation) while maintaining overall system manageability and ease of manufacture.
Solution Approach 2:
The spring-backed clamping disc acts as an intermediary between the user's manual operation and the false eyelash. It translates simple user actions into precise clamping and releasing motions, providing ergonomic control without requiring complex mechanisms.
3Productivity
If passive holding mechanism is used, then the applicator is easy to operate, but it cannot actively release the lashes for application
Solution Approach 1:
The spring mechanism operates in periodic cycles: closing to clamp the false eyelash, holding it in position, and opening to release it for application. This periodic action between clamping and releasing states enables both passive holding and active release functions within a simple spring-based system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient, ergonomic, and precise application of false eyelashes and fibers by passively holding and actively releasing them, improving user experience and application accuracy.
Implementation Method 1
employ compressive clamping forces supplied by a spring, a spring-backed clamping disc, a mechanical energy store assembly
Implementation Method 2
a spring or spring-backed grips configured to apply a compressive clamping force to retain or release
Implementation Method 3
contact surfaces (spring or discs) with a coating to repel formulation, adhesives, etc., and also to slightly hold or otherwise change the surface properties inherent in the alloy of the spring, such as self-cleaning properties from hydrophobicity
Implementation Method 4
self-cleaning properties from hydrophobicity, slippery liquid-infused porous surfaces (SLIPS)

AI summary
Applicators for grasping and applying small items, such as fibers and eyelashes, are disclosed. The applicators passively hold the items and a user actuates the applicator to release the items. An applicator includes a compression spring that forces a disc against a disc retention element to hold the items passively, and a button is pressed to separate the disc from the disc retention element to release the items. An applicator includes an expansion spring that holds items between coils of the spring passively, and a button is pressed to separate the spring coils to release the items.
