Personalized Lip Applicator via 3D Scan and Additive Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for applying makeup to the lips, particularly those seeking to alter the shape or outline, are unsatisfactory due to difficulties in achieving a clean, even, and harmonious look, especially for individuals with visual or motor skills issues, and fail to accommodate individual lip morphology effectively, leading to unsatisfactory results and reduced frequency of makeup application.
Innovation Solution
A method involving a 3D scan of the lips to create a personalized applicator with a customized application surface that can be manufactured through machining or additive manufacturing, allowing for a precise and tailored makeup application that can redefine the lip outline, enabling a professional-quality, clean, and harmonious makeup look.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a standard applicator is used to apply makeup to the lips, then the application process is simple, but the result does not conform to the three-dimensional morphology of the lips and leaves regions uncovered
Solution Approach 1:
The patent creates a digital 3D model by copying the actual geometry of the user's lips through scanning. This digital replica serves as the basis for designing a customized applicator that perfectly matches the individual's lip morphology, ensuring complete coverage while maintaining simplicity of use.
2Adaptability or versatility
If an individual attempts to modify the lip outline when applying makeup, then the desired shape change can be achieved, but the result becomes asymmetric or extends beyond the natural outline to an exaggerated degree
Solution Approach 1:
The patent incorporates feedback mechanisms where the digital 3D model of the lips allows users to visualize and adjust the desired outline modifications before application. The system provides real-time feedback on symmetry and proportion, enabling precise control over outline changes while maintaining aesthetic balance.
3Manufacturing precision
If successive removals and reapplications of makeup are performed to achieve a satisfactory result, then the outline can be refined, but the procedure becomes lengthy and irritates the mucous membranes
Solution Approach 1:
The patent performs preliminary actions by creating a precise digital 3D model of the lips and designing the optimal applicator configuration before the actual makeup application. This pre-planning ensures that the first application achieves the desired precision, eliminating the need for repeated removals and reapplications.
4Manufacturing precision
If a pencil is used to create a clean lip makeup outline, then the outline precision can be improved, but the operation becomes difficult especially when not wishing to follow the natural outline of the lips
Solution Approach 1:
The patent enables self-service by providing users with a customized applicator that automatically conforms to their unique lip morphology. The applicator is designed to guide the makeup product along the correct outline without requiring manual skill or constant adjustment, making precise application easy for users regardless of their expertise.
Applied Scientific Principles

AI summary
Method for manufacturing a personalized applicator for applying a product, notably make-up product, to keratinous materials, including a application surface. The method includes the following steps: a) applying to a surface of the keratinous materials of an individual a composition that modifies the appearance thereof, b) performing an optical acquisition of the topography of the surface thus covered and of at least one image providing information as to the location of the composition, and c) from this acquisition creating the applicator or a mold intended for the manufacture thereof.
