Nail Care System with Helical Applicator and Composite Film
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional nail polish compositions using nitrocellulose suffer from poor long wear characteristics, being either too soft and easily damaged or too hard and inflexible, while also lacking high gloss and effective adhesion.
Innovation Solution
A nail care system comprising a composition with a combination of an adhesive agent, a primary film former, a plasticizer, and optionally a co-film former, solvent, pigment, thixotropic agent, silicone acrylate copolymer, and additives, applied using an applicator with a helical patterned stem to enhance adhesion and gloss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If high levels of nitrocellulose are used to improve adhesion, then adhesion is improved, but the nail polish becomes too hard and inflexible
Solution Approach 1:
The patent changes the chemical composition parameters by replacing nitrocellulose with cellulose acetate butyrate and adjusting the ratio of plasticizers to film formers. This parameter change achieves both strong adhesion and flexibility simultaneously, resolving the contradiction between strength and adaptability.
Solution Approach 2:
The patent uses a composite material system combining cellulose acetate butyrate with specific plasticizers (tributyl citrate, diisobutyl adipate) in optimized ratios. This composite approach provides both the adhesion strength of film formers and the flexibility from plasticizers, resolving the hardness-inflection contradiction.
2Adaptability or versatility
If low levels of nitrocellulose are used to improve flexibility, then flexibility is improved, but the coated films become easily damaged
Solution Approach 1:
The patent optimizes the concentration parameters of film formers and plasticizers, maintaining film former content at 5-20% and plasticizer at 10-40%. This parameter optimization ensures sufficient film integrity for damage resistance while maintaining flexibility through adequate plasticizer content.
Solution Approach 2:
The composite system of cellulose acetate butyrate with specific plasticizers creates a balanced material properties profile where the film former provides structural integrity (damage resistance) and plasticizer provides flexibility, resolving the contradiction between strength and adaptability.
3Strength
If traditional nail polish composition is used to achieve adhesion, then adhesion is achieved, but long wear characteristics are poor
Solution Approach 1:
The patent changes the compositional parameters by using cellulose acetate butyrate instead of nitrocellulose and optimizing the plasticizer to film former ratio. This parameter change results in films that maintain adhesion strength while significantly improving wear resistance and durability over 7-10 days.
Solution Approach 2:
The composite material system with cellulose acetate butyrate, tributyl citrate, and diisobutyl adipate creates a formulation where adhesion and wear resistance work synergistically. The specific composition ratios ensure both strong initial adhesion and sustained long-term wear performance.
4Strength
If nitrocellulose is used as adhesive agent, then adhesion is improved, but gloss is not high
Solution Approach 1:
The patent changes the adhesive agent from nitrocellulose to cellulose acetate butyrate and optimizes the plasticizer content at 10-40%. This parameter change simultaneously achieves strong adhesion and high gloss finish, as the new composition system provides both bonding strength and optical properties.
Solution Approach 2:
The composite system combining cellulose acetate butyrate with specific plasticizers creates a material that exhibits both strong adhesion properties and high gloss. The synergistic interaction between film former and plasticizer in the composite provides dual functionality of bonding and optical enhancement.
