Innovation Solution

A novel artificial leather structure comprising a base fabric with a polyvinyl chloride film, a bonding layer, a patterned foam layer, a color layer, and a surface treatment layer, allowing for multiple three-dimensional patterns and colors, achieved through a manufacturing process involving coating, drying, and hot-pressing to form the layers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional PVC foam artificial leather is used, then it provides basic functionality for furniture and automotive interiors, but it lacks light weight, color diversification, and design enhancement

Engineering Contradiction:
Improvecolor diversificationVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The artificial leather is divided into multiple functional layers including base fabric, bonding layer, foam layer, color layer, and surface treatment layer. Each layer serves a specific function and can be independently optimized, enabling color diversification while maintaining manageable structural complexity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention introduces a multi-layered vertical structure with distinct functional zones. The color layer and foam layer are positioned at different depths, allowing color patterns to be embedded within the structure rather than just on the surface, thereby achieving color diversification without proportionally increasing overall structural complexity

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Manufacturing precision

If multiple layers are added to achieve three-dimensional patterns and colors, then aesthetic and functional properties are improved, but manufacturing process complexity increases

Engineering Contradiction:
Improvepattern precisionVSAvoidmanufacturing process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

Color patterns are pre-formed in the color layer before the final foam expansion process. This preliminary action ensures precise pattern positioning and allows subsequent foam layers to conform to the established color design, achieving high pattern precision while streamlining the overall manufacturing sequence

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The manufacturing process utilizes controlled thermal and pressure parameters during hot-pressing to achieve precise foam expansion and pattern formation. By optimizing temperature, pressure, and time parameters, the process achieves high pattern precision without requiring excessively complex manufacturing equipment or procedures

Inventive Principle:
Principle #35Parameter changes

3Strength

If traditional PVC foam artificial leather is used, then it provides basic durability, but it lacks lightweight properties and design enhancement

Engineering Contradiction:
ImprovedurabilityVSAvoidweight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The foam layer is designed with a controlled porous structure that provides both lightweight properties and mechanical durability. The cellular foam structure reduces density and weight while maintaining structural integrity and tensile strength, thereby achieving weight reduction without sacrificing durability

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The invention uses composite construction combining base fabric, bonding adhesive, foam polymer, color pigments, and surface treatment coatings. This composite material system optimizes the weight-strength ratio by selecting materials with high strength-to-weight ratios and combining them in a multi-layer architecture that distributes mechanical stresses effectively

Inventive Principle:
Principle #40Composite materials
