Cosmetic Ink Transfer Roller for Body Contour Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current makeup transfer systems face challenges in transferring ink quickly after printing due to rapid drying, lack of adaptability to body contours, and limited retouching capabilities, especially for curved areas like arms and facial features.
Innovation Solution
A digital printer with a non-flat transfer surface, such as a roller or pad, that allows for precise and customizable cosmetic ink application directly onto the body's contours, enabling easy transfer and retouching without solvents, and accommodating various body shapes through deformable substrates and geometrical rectification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If cosmetic ink is printed on a flat substrate, then printing precision is improved, but adaptability to curved body surfaces deteriorates
Solution Approach 1:
The patent applies curvature by transforming the flat printing surface into a curved roller that conforms to body contours. The roller's cylindrical shape allows it to adapt to curved surfaces like arms and legs while maintaining printing precision through the roller's controlled rotation and contact pressure.
Solution Approach 2:
The patent implements dynamics by making the transfer surface deformable rather than rigid. The roller can be pressed against different body parts with varying pressures, allowing the printing surface to dynamically adapt to different curvatures and shapes while maintaining consistent ink transfer quality.
2Stability of the object's composition
If ink dries quickly after printing, then storage stability is improved, but transfer capability deteriorates
Solution Approach 1:
The patent uses a specialized roller as an intermediary between the printed pattern and the skin. The roller's surface is designed to maintain ink moisture while providing transfer pressure, acting as a mediator that preserves both storage stability and transfer capability by controlling the ink's interaction with the environment.
Solution Approach 2:
The patent applies parameter changes by modifying the physical state of the ink through the roller's surface properties. The roller maintains specific temperature and humidity conditions that prevent rapid drying, changing the ink's evaporation rate and viscosity parameters to enable both stable storage and effective transfer.
3Productivity
If transfer is performed immediately after printing, then transfer efficiency is improved, but retouching capability deteriorates
Solution Approach 1:
The patent applies preliminary action by preparing the ink in a state that allows both immediate transfer and subsequent retouching. The roller's surface treatment and ink formulation create a preliminary condition where the ink remains workable for retouching while still being transferable immediately, eliminating the need to choose between the two options.
4Device complexity
If flat transfer surfaces are used, then device complexity is reduced, but adaptability to reliefs deteriorates
Solution Approach 1:
The patent uses curvature to solve the contradiction by replacing flat surfaces with a cylindrical roller. This geometric change provides adaptability to reliefs and curved body surfaces while adding minimal complexity, as the roller is a simple rotational component that can be integrated into existing printing mechanisms.
