Cosmetic Applicator Geometry Module for Eye Makeup Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic applicators, such as eyeliner, are difficult to use for applying makeup around the eye, especially for wing eye makeup, requiring high skill and not easily accessible for general users.
Innovation Solution
A cosmetic applicator with a geometry module that guides the application of makeup, featuring a detachable cap unit and a geometry portion with curved lines, allowing for various shapes and easy application around the eye.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional cosmetic applicator (eyeliner) is used to apply makeup around the eye, then the application process requires high skill and is difficult to perform, but the device structure remains simple
Solution Approach 1:
The cosmetic applicator is divided into multiple detachable components: a first body containing cosmetic, a second body forming a cap unit, and an optional third body. This segmentation allows the device to provide guidance functionality through attachable geometry modules while keeping the base structure simple and familiar to users.
Solution Approach 2:
A geometry module with curved line portions acts as an intermediary guide between the user's hand and the application target. This intermediary component provides visual and physical guidance for creating wing eye makeup, bridging the gap between simple applicator design and complex guidance functionality.
2Manufacturing precision
If a geometry module with curved line portions is added to guide makeup application, then application precision and ease of use improve, but the device complexity increases
Solution Approach 1:
The geometry module is designed to be detachably coupled to the second body, allowing the device to dynamically adjust between a simple cap unit configuration and an enhanced guidance configuration. This dynamic adaptability enables precision guidance when needed while maintaining simplicity for routine applications.
Solution Approach 2:
The second body serves multiple functions: it acts as a protective cap for the tip, a holder for the geometry module, and part of the application device itself. This multi-functionality reduces the need for separate components, managing device complexity while providing guidance capabilities.
3Adaptability or versatility
If the cap unit is detachably coupled to the drawing unit, then the device becomes more versatile and easier to maintain, but the device complexity increases
Solution Approach 1:
The detachable coupling between the first body (drawing unit) and second body (cap unit) divides the device into separable functional modules. This segmentation enables versatility by allowing different configurations and easy maintenance of individual components without affecting the entire device.
Solution Approach 2:
The detachable design allows the cap unit to be easily removed, cleaned, or replaced independently from the drawing unit. This facilitates maintenance and extends device life by enabling recovery and reuse of components rather than discarding the entire device.
