Solution Overview
Problem
Existing decorative materials lack the ability to effectively increase color variation on their front face while maintaining high saturation and depth, as they often rely on fixed pigment compositions and structures.
Innovation Solution
A decorative material comprising a base material laminated with a first opaque synthesis resin cover layer containing coloring and bright pigments, and a second transparent synthesis resin cover layer with a lower concentration of coloring pigments, where the L* value difference in the L*a*b* color system is set to be equal to or greater than 20, allowing for adjustable color variation and enhanced saturation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-layer structure with fixed pigment composition is used, then manufacturing simplicity is maintained, but color variation and saturation on the front face are insufficient
Solution Approach 1:
The decorative material is divided into multiple cover layers (first cover layer with opaque synthesis resin containing bright pigment, second cover layer with transparent synthesis resin containing coloring pigment) to enable independent optimization of color properties in each layer, achieving enhanced color variation and saturation while maintaining manufacturing feasibility
Solution Approach 2:
The patent combines different types of pigments (bright pigment in first layer, coloring pigment in second layer) with different resin materials (opaque synthesis resin, transparent synthesis resin) to create a composite multi-layer structure that achieves superior color variation and saturation effects compared to single-layer structures
2Adaptability or versatility
If high concentration of coloring pigment is used in the second cover layer, then color saturation is improved, but color variation and depth are reduced
Solution Approach 1:
The patent applies different pigment concentrations and types to different layers: the first cover layer contains bright pigment for luminosity, while the second cover layer contains coloring pigment at optimized concentrations to provide color saturation without excessive density, achieving both color variation and depth through localized quality differentiation
Solution Approach 2:
The patent optimizes the concentration parameter of coloring pigment in the second cover layer and controls the L* value difference (≥20) between layers to achieve the desired balance between color saturation and color variation, demonstrating parameter optimization to resolve the contradiction
3Adaptability or versatility
If the L* value difference between layers is small, then manufacturing precision requirements are reduced, but color variation and visual depth are insufficient
Solution Approach 1:
The patent establishes a specific parameter threshold (L* value difference ≥20) between the first and second cover layers to ensure sufficient color variation and visual depth while providing a clear manufacturing target that balances precision requirements with visual effectiveness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables significant color variation and high saturation on the front face of the decorative material, providing depth and a sense of luminosity by varying the content and material of the second coloring pigment in the second cover layer without altering the first cover layer's color, thus enhancing the overall visual appeal.
Implementation Method 1
the L* value difference in the L*a*b* color system of JIS Z 8781-4 between the first cover layer and the second cover layer in highlight is equal to or greater than 20
Implementation Method 2
a second cover layer that is laminated on the first cover layer, covers the first cover layer, and is made of chromatic and transparent synthesis resin
