Solution Overview

Problem

Existing decorated wall and floor panels, particularly those based on wood materials, have limitations in fire safety and design variety, with mineral coverings offering improved fire resistance but limited decorative options, and existing methods for producing such panels can be improved for user applicability and haptic realism.

Innovation Solution

A decorated and surface-structured panel is created using a fiber cement board with a carrier plate, primer layer, decorative layer, radiation-curable varnish layer, structured plastic film, and topcoat layer, incorporating specific fiber materials and additives to enhance stability and manufacturability, and a method involving direct printing, radiation curing, and embossing to achieve a realistic haptic effect.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wood-based panels are used for decorative wall or floor panels, then decorative variety and tactile effect are improved, but fire resistance deteriorates

Engineering Contradiction:
Improvedecorative varietyVSAvoidfire resistance
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies composite materials by combining a fiber cement board (mineral-based, fire-resistant) as the core substrate with multiple decorative and protective layers including printed decorative layers, embossed plastic films, and radiation-curable lacquers. This composite structure allows the panel to achieve both the fire resistance of mineral materials and the decorative variety of wood-based panels, directly resolving the technical contradiction between fire safety and decorative versatility

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If mineral wall or floor coverings are used, then fire resistance is improved, but decorative variety deteriorates

Engineering Contradiction:
Improvefire resistanceVSAvoiddecorative variety
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The invention creates a composite structure where the fiber cement board provides the fire-resistant mineral base, while additional layers (decorative print layers, embossed plastic films, and protective lacquers) are applied to achieve wood-like decorative effects and tactile sensations. This allows mineral coverings to overcome their traditional limitation in decorative variety while maintaining fire resistance

Inventive Principle:
Principle #40Composite materials

3Adaptability or versatility

If a surface texture is applied to improve realistic appearance, then haptic realism is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvehaptic realismVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-embossing the plastic film with the desired surface texture (such as wood grain patterns) before applying it to the panel. This pre-structuring of the film simplifies the manufacturing process compared to creating textures directly on the finished panel, as the embossing can be done in advance using standardized embossing rollers or plates, thereby reducing overall manufacturing complexity while achieving high haptic realism

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The plastic film serves as an intermediary carrier that can be independently embossed with complex surface structures before being applied to the panel. This intermediary approach allows the complex texturing operation to be separated from the main panel assembly process, making the manufacturing more manageable and enabling high haptic realism without proportionally increasing overall manufacturing complexity

Inventive Principle:
Principle #24Intermediary (Mediator)
