Amber Varnish UV Ink Coating for Diamond Pattern Protection

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Decorative products with semitransparent films applied over UV ink coatings tend to deteriorate over time due to UV exposure, leading to fading and loss of brilliance in the diamond patterns, which devalues the appearance and quality of the products.

Innovation Solution

Applying an Amber Varnish Solution as a protective coating over the UV ink coating layer, which is printed using Raised UV Coatings or 3D UV printing techniques, to stabilize and enhance the diamond pattern's appearance, combined with a polyurethane layer for added shine and protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a semitransparent film is applied over UV ink coating to enhance jewel-shaped appearance, then the reflectance and brilliance are improved, but the film deteriorates over time due to UV exposure causing fading and loss of brilliance

Engineering Contradiction:

ImprovereflectanceVSAvoiddurability

Core Design Contradiction:

Illumination intensityVSReliability

Solution Approach 1:

The patent introduces an amber varnish layer as an intermediary protective coating between the UV ink coating and the external environment. This amber varnish acts as a mediator that filters UV rays and protects the underlying UV ink from degradation, thereby preventing fading while maintaining the brilliance and reflectance of the jewel-shaped design.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the optical parameters of the protective coating by using amber varnish instead of clear or other colored varnishes. The amber varnish specifically filters UV radiation while allowing visible light to pass through, maintaining the brilliance and reflectance properties of the UV ink coating while providing protection against UV-induced deterioration.

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If UV ink coating is applied directly without protective layer, then the manufacturing process is simplified, but the ink peels and deteriorates due to abrasive activity

Engineering Contradiction:

Improvecoating process complexityVSAvoidresistance to abrasion

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent creates a composite coating system consisting of multiple layers: the UV ink coating layer and the amber varnish protective layer. This composite structure combines the decorative properties of UV ink with the protective properties of amber varnish, providing both aesthetic appeal and resistance to abrasion, peeling, and fading.

Inventive Principle:

Principle #40Composite materials

3Illumination intensity

If diamond pattern is obstructed by film deterioration, then the appearance quality decreases, but the film is necessary to enhance the jewel-shaped appearance

Engineering Contradiction:

ImprovebrillianceVSAvoidUV degradation

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful effect of UV radiation into a beneficial protective mechanism. The amber varnish layer is specifically designed to filter and block UV rays while allowing the desired optical effects (brilliance and reflectance) to pass through. This transforms the problematic UV exposure into a controlled protective barrier that prevents degradation of the diamond pattern.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
