Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nail enhancements such as gels and dip powders are difficult to remove without damaging the nail, leading to potential health issues and discomfort.
Innovation Solution
A multilayer nail coating system comprising a nail primer layer and a nail powder layer with particles that undergo a phase or shape transition upon exposure to a removal stimulus, allowing for easy detachment of nail enhancements without causing significant damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If gel products are used to achieve long-lasting nail enhancements, then mechanical robustness and longevity are improved, but difficulty of removal and potential damage to the nail worsen
Solution Approach 1:
The nail enhancement system is divided into multiple layers with distinct functions: a base coat layer, a color coat layer, and a top coat layer. Each layer can be independently formulated and applied, allowing the base coat to provide strong adhesion and durability while the top coat provides a protective seal that can be selectively removed or modified to facilitate easy removal without damaging the natural nail.
Solution Approach 2:
The patent employs photopolymerization as the curing mechanism, where UV or LED light triggers a chemical reaction that transforms the liquid monomer/oligomer mixture into a solid crosslinked polymer network. This parameter change (from liquid to solid state through light exposure) enables the formation of a mechanically robust coating that is also designed to be easily removed through controlled degradation or solvent interaction, resolving the contradiction between durability and removableness.
2Ease of operation
If conventional nail polishes are used for easy removal, then ease of removal is improved, but mechanical robustness and longevity worsen
Solution Approach 1:
The nail enhancement uses a composite formulation combining monomers, oligomers, and polymers in specific ratios within the base coat, color coat, and top coat layers. This composite material structure provides both the mechanical robustness needed for long-lasting wear and the controlled solubility or degradability required for easy removal, eliminating the need to choose between ease of removal and longevity.
3Ease of operation
If aggressive removal methods are used to remove gel products, then ease of removal is improved, but harmful factors affecting the nail worsen
Solution Approach 1:
The top coat layer serves as an intermediary protective seal between the nail enhancement and the external environment. During removal, this top coat can be selectively removed or softened through controlled means (such as specific solvents or heat treatment), allowing the underlying layers to be removed more easily and with less mechanical trauma to the natural nail, thus reducing harmful factors while maintaining ease of removal.
