Digital Cosmetic Ink Transfer for Keratin Pattern Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for applying precise makeup patterns on keratin materials, such as the skin or lips, are inefficient and prone to degradation due to skin movement, limited pattern options, and instability over time, especially when exposed to environmental factors like sweat or rain.
Innovation Solution
A process using a digital printer to create a cosmetic ink pattern on a substrate, which is then transferred to the skin without an adhesive layer, followed by a protective coating formed from a film-forming polymer composition to enhance pattern stability and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a patch or decal transfer method is used to apply makeup patterns, then the pattern can be transferred to the skin, but the support becomes cracked due to facial skin movements, giving a degraded and unaesthetic visual result
Solution Approach 1:
The patent removes the adhesive layer and support structure from the transfer process. Only the cosmetic ink pattern is transferred to the skin, eliminating the source of cracking and degradation that comes from the rigid support bearing the pattern.
Solution Approach 2:
The patent introduces a receiver sheet as an intermediary carrier that holds the cosmetic ink pattern during transfer. This flexible receiver sheet can adapt to facial skin movements without cracking, unlike rigid patches or decals, while still enabling precise pattern transfer.
2Adaptability or versatility
If conventional makeup coatings are applied to achieve pattern coverage, then the area can be decorated, but the pattern lacks stability and deteriorates quickly when exposed to sweat, rain, or touching
Solution Approach 1:
The patent uses a composite structure consisting of the receiver sheet and cosmetic ink pattern together as a transfer unit. This composite allows for easy transfer while maintaining pattern integrity, and the pattern itself is designed to be stable against environmental factors like sweat and rain.
3Manufacturing precision
If a professional makeup artist draws a pattern by hand to achieve precise deposition, then the pattern can be created with attention to detail, but the process takes a long time and requires professional intervention
Solution Approach 1:
The patent uses a receiver sheet that can be printed with patterns using a digital printer, creating a reproducible template that can be transferred to the skin. This allows precise patterns to be generated quickly through printing technology rather than manual drawing, significantly increasing application speed while maintaining precision.
4Stability of the object's composition
If the cosmetic ink is applied completely dry on the substrate before transfer, then the pattern may be more stable on the substrate, but the transfer quality and precision are reduced
Solution Approach 1:
The patent applies the cosmetic ink pattern to the receiver sheet in advance, allowing it to dry and stabilize on the substrate before the transfer process. This preliminary action ensures the ink is stable on the receiver sheet while still enabling high-quality transfer to the skin when needed.
