Artificial Eyelash Preparation Using Disposable Adhesive Tape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artificial eyelashes cause discomfort and eye irritation due to glue residuals and uneven curing, leading to issues like itchiness, blurred vision, and a foreign body sensation.
Innovation Solution
A method for preparing artificial eyelashes involves arranging eyelash extensions in a mold, bonding them with double-sided adhesive tape, trimming, curling, and soaking in solutions to enhance comfort and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If liquid glue is used to secure the lash band during manufacturing, then the eyelashes can be assembled and shaped, but glue residuals remain on the surface causing eye irritation and discomfort during wear
Solution Approach 1:
The patent removes the harmful adhesive tape from the final product structure. Instead of using traditional liquid glue that leaves residuals, the invention uses a tape-based bonding system where the tape is completely removed after serving its temporary assembly function, leaving no harmful residues on the eyelashes or user's eyes.
Solution Approach 2:
The adhesive tape is designed as a temporary, disposable bonding medium that is applied during manufacturing and then completely removed. The tape serves its purpose during assembly and shaping, then is discarded along with any residual adhesive, preventing long-term eye irritation while enabling the manufacturing process.
2Manufacturing precision
If manual processing is used for preparation, trimming, and shaping, then flexibility and precision can be achieved, but production efficiency is low and labor costs are high
Solution Approach 1:
The manufacturing process is divided into distinct modular stages: assembly (using adhesive tape), shaping (using shaping tubes and clips), and finishing (removal of tape and residual adhesive). This segmentation allows each stage to be optimized independently, with manual precision where needed and automated processes where feasible, improving both efficiency and precision.
Solution Approach 2:
The patent changes the bonding parameter from liquid glue to adhesive tape, which fundamentally alters the manufacturing process. This parameter change enables better control over the bonding characteristics, allowing for more precise assembly and easier removal, while also facilitating standardized production processes that can be scaled efficiently.
3Stability of the object's composition
If the adhesive tape is not completely removed, then the bonding structure remains stable, but it causes a foreign body sensation and discomfort during wear
Solution Approach 1:
The invention completely extracts and removes the adhesive tape from the final product. The tape and any residual adhesive are entirely removed after serving their temporary bonding function during manufacturing, eliminating the foreign body sensation while maintaining the structural integrity of the eyelash assembly through alternative means.
Solution Approach 2:
The temporary adhesive tape, which could be considered harmful if left behind, is converted into a beneficial temporary bonding solution during manufacturing. Its complete removal is then achieved as a final step, transforming the potential harm into a useful temporary measure that enables precise assembly without long-term adverse effects.
4Strength
If traditional curing processes are used for liquid glue, then bonding strength is achieved, but uneven curing creates irritation and discomfort
Solution Approach 1:
The adhesive tape is designed as a temporary bonding medium that does not require complex curing processes. It provides sufficient bonding strength during manufacturing and assembly, then is completely removed, eliminating the problem of uneven curing that plagues liquid glue systems.
Solution Approach 2:
The patent replaces the chemical curing process of liquid glue with a mechanical bonding system using adhesive tape. This substitution eliminates the need for curing time and temperature control, providing consistent bonding strength without the variability and irritation caused by uneven curing.
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 method reduces eye irritation and discomfort by minimizing glue residuals and enhancing the comfort and transparency of the eyelashes, improving manufacturing efficiency and aesthetic quality.
Implementation Method 1
the shaping pieces are placed into a steam pot for heating, that will cause the eyelash fibers to maintain a curled shape
Implementation Method 2
The waterproof paper and the upper part of the eyelashes are wrapped around a shaping tube causing the eyelashes to curl around the tube
Implementation Method 3
at least two of the single piece eyelashes are bonded together in a desired arrangement by a double-sided adhesive tape to form a semi-finished product of eyelashes
