Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Odorless monomers used in artificial nail systems often result in a tacky surface due to reaction with atmospheric oxygen, hindering market penetration and requiring additional steps to remove, which pose health risks and are not practical.
Innovation Solution
A method involving a barrier layer impervious to oxygen is applied over an acrylic layer made of odorless methacrylate monomers, allowing polymerization to complete without oxygen exposure, using co-initiators, UV light initiators, and additives to prevent yellowing, and employing cyanoacrylate glue or other oxygen-impermeable coatings for anionic curing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If odorless monomers are used for polymerization, then the artificial nail system becomes safer and more appealing, but a tacky surface forms due to oxygen reaction
Solution Approach 1:
A barrier layer is introduced as an intermediary component between the monomer layer and atmospheric oxygen. This barrier layer prevents oxygen from reaching the polymerizing monomers, eliminating the tacky surface formation while allowing the use of safe, odorless monomers. The barrier layer acts as a mediator that blocks the harmful oxygen-monomer interaction.
Solution Approach 2:
The patent creates an oxygen-excluded environment by applying a barrier layer that is impervious to oxygen. This effectively creates an inert atmosphere condition at the nail surface, preventing oxygen from interfering with the polymerization process and allowing complete curing without tackiness.
2Manufacturing precision
If polymerization is carried out in nitrogen or argon atmosphere, then tack-free surface is achieved, but the process becomes complex and impractical
Solution Approach 1:
Instead of requiring complex nitrogen or argon atmosphere equipment, the patent uses a simple barrier layer as an intermediary. This layer is applied directly to the nail surface before monomer application, creating the necessary oxygen-excluded environment without requiring specialized gas handling equipment or complex atmospheric control systems.
Solution Approach 2:
The barrier layer is applied as a thin film or coating on the nail surface. This flexible, thin-film approach creates an effective oxygen barrier without adding significant complexity to the application process, making it practical for salon use compared to gas atmosphere systems.
3Manufacturing precision
If wax is added to eliminate tacky surface, then polymerization proceeds to completion, but the wax flakes off and the solution is ineffective
Solution Approach 1:
The barrier layer serves as a stable intermediary that remains in place during polymerization, unlike wax which flakes off. This barrier layer continuously blocks oxygen from reaching the polymerizing monomers throughout the entire process, ensuring complete curing and maintaining coating integrity without the instability problems of wax-based solutions.

AI summary
A method and kit for providing a tack-free artificial nail surface. The tack-free artificial nail surface may include an acrylic layer and a barrier layer. The acrylic layer may comprise an odorless monomer. The barrier layer may be of any material impervious to oxygen. The tack-free nail surface may be formed by application of the acrylic layer to a fingernail nail bed. The barrier layer may then be applied over the acrylic layer. The barrier layer blocks oxygen from the acrylic layer so that the acrylic layer may polymerize in the absence of oxygen.
