Solution Overview

Problem

Existing tiles for wall, floor, or ceiling covering lack durability, vandalism resistance, ease of maintenance, and the ability to display highly realistic images that evoke the intended emotions, particularly in public spaces and applications requiring chemical inertness or magnetic properties.

Innovation Solution

A metal-ceramic tile structure comprising a metal layer, a chemically bonded enamel layer, and an image printed in glass ink, with one or more overlay layers applied to enhance texture and realism, using either screen printing or digital printing processes to create a three-dimensional surface that mimics natural materials and improves tactile experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional pressing or laser texturing is used to create surface texture, then the tile achieves more realistic appearance, but the manufacturing cost and process complexity increase significantly

Engineering Contradiction:
Improvesurface texture realismVSAvoidmanufacturing process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent changes the manufacturing approach from mechanical/laser texturing to a chemical deposition process using silver nitrate solution. By controlling parameters such as solution concentration, exposure time, and heating temperature, the patent achieves realistic surface texture without complex manufacturing equipment. The silver crystal formation parameters are adjusted to create varying degrees of texture realism.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If ceramic tiles are used for durability and chemical inertness, then the tile resists vandalism and chemical damage, but the tile lacks magnetic properties and can still crack under strong vibrations

Engineering Contradiction:
Improvevandalism resistanceVSAvoidmagnetic property capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent creates a composite structure by depositing silver crystals on the ceramic tile surface. The base ceramic provides durability, chemical inertness, and vandalism resistance, while the silver crystal layer adds magnetic properties and enhances visual realism. This composite approach allows the tile to simultaneously possess properties from different materials without compromising the base ceramic's strength.

Inventive Principle:
Principle #40Composite materials

3Ease of operation

If smooth glossy ceramic surfaces are used, then the tile is easy to clean and maintain, but the tile cannot evoke the warmth and realism of natural materials like wood or stone

Engineering Contradiction:
Improvemaintenance easeVSAvoidmaterial realism
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent applies local quality by creating texture only in specific areas where realism is needed, rather than making the entire surface rough. The silver crystal deposition can be controlled to create texture in patterned areas while leaving other areas smooth and glossy for easy cleaning. This selective texturing maintains maintenance ease while adding material realism where required.

Inventive Principle:
Principle #3Local quality

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 provides a strong, durable, and vandalism-resistant tile that easily maintains realistic and emotive images, enhancing the tactile experience and realism of materials like wood, stone, and metal, while being suitable for various applications due to its chemical inertness and improved maintenance.

Implementation Method 1

The texture is formed by a chemical reaction between an organic material on a surface of the tile and a silver nitrate solution

AI summary

A tile (100; 203; 303) for wall, floor or ceiling covering, comprising: - a first layer (101 ) consisting of metal; - a second layer (102) consisting of enamel, is chemically bonded to the first layer (101 ); - a third layer (103) consisting of an image (201; 301 ) in glass ink printed onto the second layer (102); and - one or more overlay layer (104) which is printed onto the third layer (103), using that same image (201; 301 ), and which only partially covers the third layer (103) such that texture is given to the surface of the tile (100; 203; 303) and a more realistic impression of said image (201; 301 ) is created.
