Plasma Nail Pretreatment for Solvent-Free Coating Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nail coating methods, such as polishing and using organic solvents, cause nail weakening, discoloration, and poor adhesion, while existing plasma treatments lack specificity in gas types and focus on bleaching rather than pretreatment for improved adhesion.
Innovation Solution
Using nitrogen, oxygen, or carbon dioxide gases to generate atmospheric pressure plasma for pretreatment of nails before or during nail coating, eliminating the need for polishing and organic solvents, and improving adhesion through plasma irradiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polishing is performed to improve adhesion, then adhesion is improved, but nail strength decreases and whitening occurs
Solution Approach 1:
The patent replaces mechanical polishing with plasma irradiation treatment. The plasma treatment activates the nail surface chemically without mechanical abrasion, creating adhesive functional groups while preserving nail integrity and avoiding whitening caused by mechanical damage.
Solution Approach 2:
The patent changes the surface state parameters of the nail through plasma treatment. By controlling plasma parameters (gas type, power, treatment time), the surface is modified to have increased surface energy and adhesive functional groups without changing the physical structure or thickness of the nail plate.
2Reliability
If organic solvents are used to remove dirt and grease, then adhesion is improved, but percutaneous absorption and discoloration occur
Solution Approach 1:
The patent replaces chemical solvent-based cleaning with plasma-based surface activation. The plasma treatment directly activates the nail surface without requiring organic solvents, eliminating the harmful effects of percutaneous absorption and discoloration while maintaining effective adhesion promotion.
Solution Approach 2:
The patent introduces plasma as an intermediary between the nail surface and coating material. The plasma creates a reactive surface state that enhances adhesion without requiring organic solvents as intermediaries, thus avoiding their harmful effects.
3Reliability
If conventional plasma treatment is used, then adhesion is improved, but the gas type is not specified and bleaching focus replaces pretreatment
Solution Approach 1:
The patent specifies and optimizes plasma parameters including gas type (nitrogen, oxygen, carbon dioxide, or mixtures), power levels, and treatment durations. This parameter optimization ensures the plasma treatment functions as effective pretreatment for adhesion rather than focusing on bleaching effects.
