Nail Art Molding with Thickness Gradient and Inclined Side
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nail arts have issues with wear resistance, adhesive strength, and three-dimensional appearance due to their vertical side and upper surfaces, leading to easy wear and limited light reflection.
Innovation Solution
A method for preparing nail art involves applying pressure to a laminate with a mold, where the temperature of the mold is between 55° C to 170° C and the pressure is 6 MPa to 12 MPa, to form a nail art with a substrate and coating layer, achieving a thickness gradient that enhances wear resistance and three-dimensionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the side surface and upper surface of the nail art are made vertical to each other, then the manufacturing process is simple, but the wear resistance decreases and adhesive strength reduces
Solution Approach 1:
The patent applies local quality by creating different surface characteristics in different regions of the nail art. The side surface is formed with a gradual inclination angle (10-45 degrees) rather than being vertical, while the upper surface maintains its flat structure. This localized modification of the side surface geometry improves wear resistance and adhesive strength without complicating the overall manufacturing process.
2Ease of manufacture
If the side surface and upper surface of the nail art are made vertical to each other, then the manufacturing process is simple, but the adhesive strength reduces
Solution Approach 1:
The patent modifies only the side surface geometry with a gradual inclination angle while keeping the upper surface structure simple and easy to manufacture. This localized change improves adhesive strength by creating better contact area and stress distribution at the bonding interface, without requiring complex manufacturing processes.
3Device complexity
If the side surface and upper surface of the nail art are made vertical to each other, then the structure is simple, but the three-dimensional appearance is lost
Solution Approach 1:
The patent applies asymmetry by creating a non-vertical side surface with a gradual inclination angle that transitions from the upper surface. This asymmetric geometry enhances the three-dimensional appearance and light reflection properties, while the overall structure remains relatively simple and easy to manufacture using conventional molding techniques.
