Cosmetic Applicator With Stamp Means for Winged Eyeliner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for applying winged eyeliner are difficult to execute consistently, resulting in uneven and imprecise applications, requiring significant skill and practice, especially when trying to achieve a symmetrical look.
Innovation Solution
A cosmetic applicator with a body containing an ink reservoir and a stamp means with a shape suitable for creating a winged eyeliner effect, allowing for precise and reproducible application by imprinting cosmetic ink onto the skin, featuring a pair of applicators with mirror-image stamps for identical application on each eye.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional manual methods are used to apply winged eyeliner, then the user can control the application process, but the application is difficult to execute consistently and requires significant skill and practice
Solution Approach 1:
The patent uses a stamp means that replicates the desired winged eyeliner shape directly onto the skin. The stamp means has a pre-formed shape that creates a consistent imprint, copying the target geometry without requiring the user to manually draw or freehand the shape. This resolves the contradiction by providing both precision (through the pre-formed stamp shape) and ease of operation (through simple pressing motion).
Solution Approach 2:
The stamp means is pre-formed with the exact shape of the desired winged eyeliner before use. This preliminary formation of the shape allows the user to simply press the pre-shaped stamp onto the skin rather than manually creating the shape during application. This eliminates the need for skill and practice while maintaining consistent precision.
2Manufacturing precision
If a stamp device is used to create the winged effect, then the shape can be replicated, but the cosmetic ink application is often uneven and imprecise requiring manual filling in
Solution Approach 1:
The patent combines the stamp means with an ink reservoir and dispensing mechanism into a single integrated applicator. The ink reservoir is positioned to directly supply cosmetic ink to the stamp means, ensuring that ink is delivered uniformly to the exact areas that will contact the skin. This merging of stamping and ink dispensing functions resolves the contradiction by ensuring both shape consistency and reliable uniform ink application without requiring manual intervention.
3Device complexity
If a single stamp shape is used for both eyes, then the device is simpler, but the user must rely on their artistic skill to adapt the stamp to both eyes
Solution Approach 1:
The patent designs the stamp means with a universal shape that is specifically configured to work on both eyes. The stamp shape is created to be symmetric or asymmetric in a way that allows it to be applied to either eye without requiring modification or adaptation. This universal design resolves the contradiction by maintaining device simplicity while eliminating the need for user artistic skill through proper geometric design.
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 accurate and precise creation of a uniform winged eyeliner shape on both eyes without requiring extensive artistic ability or practice, ensuring even and identical application.
Implementation Method 1
a body containing an ink reservoir arranged to hold a quantity of a cosmetic ink, the ink reservoir in fluid communication with a stamp means
Data Source
AI summary
A cosmetic applicator is provided, which has particular suitability for use in applying eye make-up such as eyeliner. The cosmetic applicator generally comprises a body with an ink reservoir located inside. The ink reservoir is in fluid communication with at least one stamp means. A surface of the stamp is contacted or pressed against skin of the user and cosmetic ink is printed on the skin surface in the shape of the surface. The stamp means can be provided in a shape suitable for creating a cat-eye or winged eyeliner effect. A method of using the cosmetic applicator and method of applying a cosmetic is also described.
