Triangular Eyeliner Nib for Precision Wing Shaping and Linework
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyeliner cosmetic applicators require skill to apply accurately and conveniently, often resulting in suboptimal application of eyeliner, particularly in creating wing shapes and linework around the eye.
Innovation Solution
A cosmetic eyeliner tip with a triangular nib that allows for precise application by adjusting angles for wing shaping and linework, featuring a convex curvature for enhanced adherence and an offset design to prevent interference with the eyeball or eyelashes, along with a wedge-shaped nib for versatile handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional eyeliner applicator is used, then the application process is simple, but the precision and accuracy of eyeliner application is poor
Solution Approach 1:
The applicator tip is segmented into multiple functional surfaces: a forward face for wing shaping, lateral faces for edge definition, and a rearward edge for lid linework. Each surface is optimized for a specific application task, allowing precise control over different areas of the eye without requiring multiple separate tools.
Solution Approach 2:
The applicator utilizes rotational movement around its longitudinal axis to access different functional surfaces. By rotating the applicator to different angles, the user can switch between the forward face for stamping wings, lateral faces for outer edge definition, and rearward edge for inner lid work, adding a dimensional aspect to the application process.
2Ease of operation
If the applicator contacts the eyeball or eyelashes during application, then the user can apply liner close to the eye, but it causes discomfort or damage
Solution Approach 1:
Instead of having the entire applicator tip contact the eye area, the design inverts the approach by using only specific portions (forward face for wings, rearward edge for lid work) while keeping other portions clear. The offset nib configuration ensures that the active application surfaces can reach close to the eye without the bulk of the applicator interfering with the eyeball or eyelashes.
3Adaptability or versatility
If the user needs to create both wing shapes and linework, then complete eye makeup is achieved, but the application process becomes complex
Solution Approach 1:
The applicator is designed as a universal tool that performs multiple functions: the forward face stamps wing shapes, the lateral faces define outer edges, and the rearward edge creates lid linework. This multi-functional design eliminates the need for separate applicators for different eye makeup tasks, simplifying the overall application process while maintaining versatility.
Solution Approach 2:
The applicator is designed to be dynamic in its orientation rather than static. The user can rotate the applicator to different angles and use different surfaces depending on the specific task at hand. This dynamic adaptability allows a single applicator to handle various application scenarios including wing creation, edge definition, and lid linework without requiring multiple fixed-function tools.

AI summary
A tip for a cosmetic eyeliner allows for the convenient and accurate application of cosmetic eyeliner. The tip comprises a generally elongate cosmetic impregnated or coated body shaped to define a nib at a distal end thereof. The nib is of generally triangular cross-section along an elongate axis of the tip so as to define two lateral faces meeting at a rearward edge thereof and a forward face between the lateral faces. The forward facing and the two lateral faces meet at a point at a distal end of the nib. As such, in use, the tip allows for the convenient application of eyeliner cosmetic wherein the forward face is configured for stamping a cosmetic wing shape and an outer edge of an eye when the nib is in a first angle of rotation.
