Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current artificial nail compositions suffer from inadequate adhesion to natural nails, leading to exfoliation and detachment, which causes aesthetic discomfort and hygienic issues, and often require the use of primers or adhesives.
Innovation Solution
An artificial nail composition comprising a compound with radical polymerizable unsaturated double bonds, an acidic phosphorus compound with a P—OH bond, and a radical polymerization initiator, which improves adhesion without the need for a primer or adhesive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a lacquer coating material is used for manicure, then the application process is simple and no water is required, but the adhesion with natural nail is insufficient and exfoliation occurs within a short period
Solution Approach 1:
The patent uses a composite material system combining a polymerizable monomer (compound a), acidic phosphorus compound with unsaturated double bond (compound b), and radical polymerization initiator (compound c). This composite formulation achieves both ease of application and strong adhesion to natural nails, resolving the contradiction between operational simplicity and adhesion reliability.
Solution Approach 2:
The patent changes the chemical parameters of the coating material by incorporating specific functional groups (acidic phosphorus compounds with P-OH bonds and unsaturated double bonds) that enhance chemical bonding to keratin in natural nails. This parameter change enables the material to maintain both simple application and high adhesion strength.
2Reliability
If dental normal temperature polymerization resin is used to improve adhesion, then adhesion is enhanced compared to lacquer, but odor stimulation and operability are degraded
Solution Approach 1:
The patent modifies the chemical composition parameters by using specific polymerizable monomers and acidic phosphorus compounds that provide strong adhesion through chemical bonding to natural nails, while maintaining acceptable odor levels and operability characteristics for practical use.
Solution Approach 2:
The patent applies local quality enhancement by incorporating acidic phosphorus compounds with P-OH bonds that specifically target and bond to the keratin structure of natural nails, providing localized strong adhesion at the nail-interface while maintaining overall material operability.
3Reliability
If primer or adhesive is added to improve adhesion, then bonding strength increases, but the number of steps and device complexity increases
Solution Approach 1:
The patent merges the functions of primer and coating material into a single integrated composition. The formulation contains polymerizable monomers, acidic phosphorus compounds, and polymerization initiators that collectively provide both priming (surface preparation and bonding) and coating functions, eliminating the need for separate primer and adhesive steps.
Solution Approach 2:
The patent creates a universal artificial nail composition that performs multiple functions simultaneously: it acts as a primer for surface preparation, provides strong adhesion through chemical bonding, and serves as the decorative coating layer. This multi-functional material reduces the overall system complexity while maintaining high adhesion strength.
