Problem
Existing false eyelash application methods are intricate, difficult to apply, and require the use of separate glue and eyelashes, leading to issues with uneven glue distribution, dust sensitivity, and lengthy application times.
Innovation Solution
A cosmetic article featuring a presized adhesive layer covered with a water-soluble protective layer, which can be easily removed by wetting, allowing for direct adhesive contact and simplifying the application process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate glue bottle is used with false eyelashes, then the adhesive can be applied separately, but the application process becomes intricate and time-consuming requiring two separate articles
Solution Approach 1:
The patent combines the false eyelashes and adhesive into a single integrated article. The adhesive layer is applied directly to the base of the false eyelashes during manufacturing, eliminating the need for separate glue bottles and application steps. This merging of components directly resolves the contradiction by reducing device complexity while improving ease of operation.
Solution Approach 2:
The adhesive is pre-applied to the false eyelashes during manufacturing, performing the adhesive application action in advance. This preliminary action eliminates the need for the user to manually apply glue, thereby simplifying the application process and reducing the number of steps required while maintaining effective bonding.
2Reliability
If glue is applied to false eyelashes, then bonding is achieved, but uneven spreading results in unsightly surpluses or absences of glue
Solution Approach 1:
The adhesive is pre-applied under controlled manufacturing conditions, ensuring uniform distribution before the product reaches the consumer. This preliminary action under controlled conditions eliminates the variability introduced by manual application, achieving both reliable bonding and uniform adhesive distribution.
Solution Approach 2:
The manual mechanical application of glue by the user is replaced with an automated adhesive application process during manufacturing. This substitution ensures precise and uniform adhesive distribution through controlled dispensing mechanisms, eliminating the uneven spreading that occurs with manual application.
3Reliability
If glue is applied to false eyelashes, then bonding is achieved, but partial drying time is required making the application long
Solution Approach 1:
The adhesive is pre-applied and pre-dried under controlled manufacturing conditions, performing the drying action in advance. This eliminates the waiting time required for the consumer to allow glue to dry before applying false eyelashes, significantly reducing application time while ensuring the adhesive is ready for immediate bonding.
Solution Approach 2:
The natural evaporation drying process that requires user waiting time is replaced with controlled drying processes during manufacturing. This substitution allows the adhesive to be fully or partially dried under optimized conditions before product delivery, eliminating the time loss experienced by the consumer.
4Reliability
If the adhesive layer is exposed, then bonding can occur, but the adhesive becomes tacky and attracts dust requiring rigorous cleanliness
Solution Approach 1:
The protective layer is applied only to the adhesive portion of the false eyelash base, leaving the eyelash fibers themselves unprotected. This localized protection maintains bonding capability where needed while preventing dust attraction only on the adhesive surface, allowing the product to be handled without rigorous cleanliness requirements.
Solution Approach 2:
A protective layer is introduced as an intermediary between the adhesive and the environment during storage and handling. This protective layer prevents dust and contaminants from adhering to the tacky adhesive surface, eliminating dust sensitivity while allowing the adhesive to remain effective for bonding when activated.
5Ease of operation
If presized false eyelashes with adhesive are made, then application is simplified, but the adhesive layer is sensitive to dust and requires rigorous handling conditions
Solution Approach 1:
The protective coating is applied locally only to the adhesive area of the false eyelash base, not to the entire false eyelash structure. This localized protection maintains ease of application while specifically addressing dust sensitivity only where the adhesive is present, allowing comfortable handling without rigorous cleanliness requirements.
Solution Approach 2:
A removable protective layer serves as an intermediary barrier during storage and handling, protecting the adhesive from dust and contaminants. This protective layer can be easily removed or dissolved at the time of application, maintaining simplicity of use while eliminating dust sensitivity during the product lifecycle.
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 solution enables easy, rapid, and dust-resistant application of false eyelashes without the need for separate glue, reducing application time and improving user convenience.
Implementation Method 1
The protective layer may be at least partially removed by wetting it, preferably with water or an aqueous solution, which brings about the at least partial dissolution of the water-soluble polymer
Implementation Method 2
the adhesive material maintains its cohesion during the wetting of the protective layer, and conserves its adhesive properties after possible evaporation of the water present on its surface
Implementation Method 3
conserves its adhesive properties after possible evaporation of the water present on its surface, used to remove the protective layer
