Eyelash Extension Case with Self-Adhesive Gel Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyelash extension storage solutions fail to securely and gently retain eyelash extensions during storage and transport, often causing damage due to movement and improper orientation.
Innovation Solution
An eyelash extension case with internal protrusions made from self-adhesive super-gel material that extends from the floor towards the lid, providing a curved surface to securely hold and retain eyelash extensions, reducing movement and damage through reusable adhesive properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional storage solutions are used, then the case structure is simple, but the eyelash extensions are not securely retained and suffer damage from movement
Solution Approach 1:
The patent applies local quality by incorporating self-adhesive super-gel material specifically on the protrusions within the storage compartments, rather than making the entire case adhesive. This localized application provides secure retention exactly where needed (on the protrusions that contact the eyelash extensions) while keeping the rest of the case structure simple and non-adhesive, thus resolving the contradiction between reliable retention and structural simplicity.
Solution Approach 2:
The patent employs curved protrusions with rounded surfaces rather than sharp or flat edges. These curved surfaces gently cradle the eyelash extensions, distributing contact pressure evenly and preventing damage while maintaining secure retention. The spherical/curved geometry of the protrusions allows the eyelash extensions to nestle into the contours, providing reliable holding without requiring complex mechanical structures.
2Reliability
If adhesive material is used to retain eyelash extensions, then retention reliability improves, but the material may lose adhesive properties over time
Solution Approach 1:
The self-adhesive super-gel material inherently maintains its adhesive properties over extended periods without requiring external intervention or replacement. The material is formulated to resist degradation from environmental factors such as humidity and temperature variations, allowing it to continuously serve its retention function throughout the case's service life, thus achieving both reliable retention and long duration of action.
Solution Approach 2:
The patent utilizes composite material construction by combining the self-adhesive super-gel material with the structural case material (typically rigid plastic or metal). This composite approach leverages the adhesive properties of the super-gel for retention while the structural material provides mechanical support and protection, creating a system where the adhesive component maintains its properties longer through the stabilizing influence of the composite structure.
3Reliability
If protrusions extend toward the lid, then eyelash extensions are securely held, but the internal region volume is reduced
Solution Approach 1:
The patent divides the internal storage region into multiple compartments, each containing protrusions for retaining specific eyelash extensions. This segmentation allows the protrusions to be concentrated in localized areas rather than uniformly distributed throughout the entire volume. Each compartment is optimized to hold its designated extensions securely on the protrusions, while the overall case maintains adequate total volume by efficiently organizing storage spaces rather than requiring excessive internal clearance.
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
The self-adhesive super-gel material effectively retains eyelash extensions, minimizing damage during storage and transport by maintaining adhesive properties over multiple cycles and periods, ensuring they remain securely in place despite changes in orientation or jostling.
Implementation Method 1
At least a portion of each protrusion is formed from an a self-adhesive super-gel material to retain one or more eyelash extensions
Data Source
AI summary
An eyelash extension case includes an enclosure body defining an internal region for storage of one or more eyelash extensions, and a lid operative to cover the internal region in a closed state and open to allow access to the internal region in an open state. Internal wall surfaces of the internal region form a floor, and one or more eyelash extension retaining features. Each eyelash extension retaining feature includes a protrusion that extends outward from the floor toward the lid along an axis. Each protrusion has curved wall surfaces that transition into the floor, and each protrusion further has curved wall surfaces that define an outer profile of the protrusion surrounding the axis. At least a portion of each protrusion is formed from a self-adhesive super-gel material that is relatively sticky to retain one or more eyelash extensions.
