Solution Overview

Problem

Existing high-pressure decorative laminates have a significant environmental impact due to energy-intensive processes like boiler use, regenerative thermal oxidizers, and phenolic treaters, and lack versatility in customization and sustainability.

Innovation Solution

The use of vulcanized fiber core layers, digital printing, and alternative resin impregnation methods, such as epoxy acrylic or urethane acrylic, along with melamine impregnated overlay layers, reduces the need for energy-intensive processes and allows for customizable, durable, and environmentally friendly decorative engineered surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional high-pressure decorative laminates are produced using phenolic resin impregnation and heat/pressure consolidation, then structural strength and durability are achieved, but significant environmental impact and energy consumption occur

Engineering Contradiction:

Improvestructural strengthVSAvoidenvironmental impact

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent changes the chemical parameters of the resin system by replacing phenolic resin with epoxy acrylic or urethane acrylic resins. This substitution maintains the structural strength and bonding properties while eliminating the harmful environmental factors associated with phenolic resin production and curing, directly resolving the contradiction between reliability and environmental harm.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces the traditional mechanical heat/pressure consolidation process with a chemical bonding mechanism. The epoxy acrylic or urethane acrylic resins provide inherent adhesive properties that enable layer bonding without requiring intensive thermal and mechanical processing, thereby reducing energy consumption while maintaining structural integrity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of manufacture

If traditional high-pressure decorative laminates are produced using boiler and thermal oxidizer processes, then decorative surfaces are achieved, but energy-intensive processes increase carbon footprint

Engineering Contradiction:

Improvedecorative surface productionVSAvoidenergy consumption

Core Design Contradiction:

Ease of manufactureVSUse of energy by moving object

Solution Approach 1:

The patent replaces the mechanical thermal processing system (boilers and thermal oxidizers) with a chemical self-curing resin system. The epoxy acrylic or urethane acrylic resins cure through chemical reactions at lower temperatures, eliminating the need for energy-intensive boiler and thermal oxidizer operations while maintaining decorative surface quality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the temperature and energy parameters of the manufacturing process by using resins that cure at lower temperatures through chemical reactions rather than requiring high-temperature thermal processing. This reduces energy consumption by 30-55% while achieving the same decorative surface production capability.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If conventional decorative laminates use standardized materials and processes, then manufacturing efficiency is maintained, but customization and sustainability options are limited

Engineering Contradiction:

Improvemanufacturing efficiencyVSAvoidcustomization capability

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal resin system (epoxy acrylic or urethane acrylic) that can serve multiple functions: providing structural bonding, enabling decorative surface application, and supporting various customization options. This multi-functional approach maintains manufacturing efficiency while significantly enhancing adaptability for different decorative requirements and sustainability goals.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces dynamic flexibility into the manufacturing system by using resins that can accommodate varying decorative layer compositions, thicknesses, and material types (recycled content, sustainable materials). The chemical bonding mechanism adapts to different material combinations without requiring changes to the core manufacturing process, thus maintaining productivity while enabling customization.
