Solution Overview

Problem

Conventional artificial nails, whether professionally applied or press-on, face challenges such as high cost, time consumption, poor adhesion, visibility of demarcations, and incompatibility with unique natural nail shapes, leading to durability issues and unnatural appearance.

Innovation Solution

The development of light-curable artificial nails with multiple semi-cured sections, including adhesive, strengthening, polish, and decorative layers, that can be shaped to conform to natural nails using electromagnetic radiation and pressure, providing a strong, flexible bond and natural appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional artificial nails are applied professionally or as press-on, then the application process is completed, but the cost is high and time consumption increases

Engineering Contradiction:

Improveease of applicationVSAvoidtime consumption

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

The artificial nail components (adhesive section, strengthening section, polish section, decorative section) are pre-assembled and pre-configured before application. The light-curable composition is prepared in a semi-cured state with appropriate viscosity for application, then fully cured after application to the natural nail, eliminating the need for multi-step professional application processes.

Inventive Principle:

Principle #10Preliminary action

2Ease of manufacture

If conventional artificial nails are applied professionally or as press-on, then the application process is completed, but the cost increases

Engineering Contradiction:

Improveease of applicationVSAvoidcost

Core Design Contradiction:

Ease of manufactureVSQuantity of substance

Solution Approach 1:

The artificial nail is divided into distinct functional sections: adhesive section with light-curable composition, strengthening section, polish section, and decorative section. This segmentation allows for efficient manufacturing of individual components that can be assembled into a complete artificial nail system, reducing overall production and material costs while maintaining functionality.

Inventive Principle:

Principle #1Segmentation

3Shape

If conventional artificial nails are applied, then the nail is covered, but poor adhesion and durability issues occur

Engineering Contradiction:

ImprovecoverageVSAvoidadhesion

Core Design Contradiction:

ShapeVSReliability

Solution Approach 1:

The adhesive section utilizes a light-curable composition that transitions from a semi-cured state with optimized viscosity for application to a fully cured state with high bond strength. The composition's physical and chemical parameters are specifically adjusted to ensure optimal adhesion to the natural nail surface, achieving both coverage and durability.

Inventive Principle:

Principle #35Parameter changes

4Shape

If conventional artificial nails are applied, then the nail is covered, but visible demarcations and unnatural appearance occur

Engineering Contradiction:

ImprovecoverageVSAvoidappearance quality

Core Design Contradiction:

ShapeVSManufacturing precision

Solution Approach 1:

The artificial nail incorporates a polish section with colorant and decorative section with visual effects specifically designed to match and enhance the natural nail appearance. These sections are positioned to cover the demarcation line between natural and artificial nail, creating a seamless, natural-looking result through localized aesthetic enhancement.

Inventive Principle:

Principle #3Local quality

5Shape

If conventional artificial nails are applied, then the nail is covered, but incompatibility with unique natural nail shapes leads to durability issues

Engineering Contradiction:

ImprovecoverageVSAvoidcompatibility with nail shapes

Core Design Contradiction:

ShapeVSAdaptability or versatility

Solution Approach 1:

The light-curable composition in the adhesive section is formulated to transition from a semi-cured, adaptable state during application to a cured, stable state after application. This dynamic property allows the composition to conform to various natural nail shapes and sizes during the application process, ensuring compatibility and durability across different nail morphologies.

Inventive Principle:

Principle #15Dynamics
