Self-Measuring Facial Dimensions for Personalized Applicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in applying makeup, particularly to the lips, due to difficulties in achieving a desired shape and symmetry, especially for those with visual or motor skills issues, leading to unsatisfactory results and increased time spent on application.
Innovation Solution
A method using a mobile image capture device, such as a smartphone, in conjunction with a mirror, to self-measure facial dimensions with high accuracy, allowing for the creation of personalized makeup applicators tailored to individual features through 3D printing, enabling precise and harmonious makeup application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If users attempt to modify the lip outline when applying makeup, then the desired shape can be achieved, but the result becomes asymmetric or extends beyond the natural outline to an exaggerated degree
Solution Approach 1:
The patent applies preliminary action by providing a template with pre-defined lip outline shapes before the makeup application process. The template allows users to position the desired outline shape over their lips, enabling them to see the expected result before applying makeup, thus avoiding asymmetric or exaggerated outlines.
2Manufacturing precision
If users spend more time attempting to achieve satisfactory makeup application, then the quality may improve, but the procedure becomes lengthy and irritates the mucous membranes
Solution Approach 1:
The template provides pre-defined outline shapes that guide users immediately, eliminating the need for repeated attempts and adjustments. This preliminary guidance reduces application time while maintaining quality, and prevents irritation from prolonged contact with the lips.
3Strength
If users apply dark or long-lasting makeup products, then the color intensity and durability are improved, but the difficulty of achieving symmetric and accurate application increases
Solution Approach 1:
The template provides a visual guide showing the desired outline shape and symmetry before application. This preliminary visualization helps users position dark or long-lasting products accurately, reducing the difficulty of achieving symmetric application even with challenging products.
4Manufacturing precision
If professional makeup services are used to achieve precise lip outlining, then the quality is improved, but the cost and accessibility are worsened
Solution Approach 1:
The patent enables self-service by providing a template that allows users to independently define and apply their desired lip outline shapes without professional assistance. The template makes precise outlining accessible to anyone, eliminating the need for expensive professional services.
