Self-Inking Eyeliner Stamp Pen for Symmetrical Cosmetic Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeliner products are inconvenient and messy to use for achieving symmetrical geometric shapes, such as a 'flick/wing' at the end of the eyes, as they require dipping a geometrically shaped stamp into an ink container and applying it manually.
Innovation Solution
A self-inking cosmetic applicator pen with a cylindrical body containing a reservoir for cosmetic material, featuring interchangeable nibs with a pointed end for precision and a geometrically shaped stamp pad for symmetrical application, allowing for easy and mess-free application of cosmetic products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single geometric shaped stamp is used at the end of a pen, then the shape application capability is improved, but the operation becomes inconvenient and messy due to separate dipping into ink container
Solution Approach 1:
The patent combines the ink reservoir and the geometric stamp into a single integrated pen device. The ink chamber is positioned within the pen body, and the geometric stamp is directly attached to the tip, eliminating the need for separate ink containers and dipping operations. This integration resolves the contradiction by maintaining shape application capability while significantly improving operation convenience.
2Ease of operation
If conventional eyeliner products are used, then the application process is simple, but achieving symmetrical geometric shapes is difficult
Solution Approach 1:
The pen is designed with segmented components including a replaceable geometric stamp tip and a refillable ink chamber. The geometric stamp is pre-formed with precise symmetrical dimensions, separating the shaping function from the ink delivery function. This allows users to simply stamp the pre-formed geometric shape for symmetrical results, maintaining application simplicity while achieving precision.
3Manufacturing precision
If a geometrically shaped stamp is used, then the shape definition is improved, but the dipping operation increases messiness
Solution Approach 1:
The pen incorporates a self-contained ink delivery system where the ink chamber is integrated within the pen body and the geometric stamp is permanently attached to the tip. The design eliminates the need for external dipping operations by providing a self-service mechanism where the stamp is already saturated or ready to receive ink from the integrated chamber, thereby maintaining precise shape definition while eliminating messiness.
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 precise and symmetrical application of cosmetic products to the eyes, reducing the inconvenience and mess associated with traditional methods, while allowing for easy replacement of nibs to accommodate individual preferences.
Implementation Method 1
A reservoir is carried within the cylindrical hollow body with the reservoir configured to contain a volume of a cosmetic material
Implementation Method 2
An applicator nib is carried within the nib holder and is configured to apply the cosmetic material from within the reservoir to a skin surface

AI summary
A self-inking cosmetic applicator pen eyeliner stamp pen. Applicator pen may feature a geometrically shaped stamp pad at a first end and a pen tip at another end. The stamp pad and pen tip are configured to be self-inking with via a reservoir carried within a body of the cosmetic applicator pen. The stamp pads may be formed as a uniform, or complimentary symmetrical shapes to apply a cosmetic material to the skin around a user's eyes. The present invention contemplates a left and a right pen having a stamp pad corresponding to a desired application to a user's left and right eyes. Alternatively, an applicator pen may include an applicator stamp at opposed ends thereof, corresponding to a left side stamp and a right side stamp.
