Solution Overview

Problem

Ceramic coatings used in construction lack both a pleasant thermal sensation similar to wood and adequate wear resistance, with existing solutions often compromising on one aspect for the other.

Innovation Solution

Incorporating carbonate apatite particles of sizes between 100 nanometers and 50 microns into the ceramic coating's silicoaluminate matrix, which reduces thermal conductivity and effusivity, while maintaining aesthetic and functional properties through a ceramic support body, engobe, and enamel layers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If ceramic coatings are made with traditional materials to ensure wear resistance, then durability is improved, but thermal sensation becomes unpleasantly cold

Engineering Contradiction:

Improvewear resistanceVSAvoidthermal sensation

Core Design Contradiction:

StrengthVSTemperature

Solution Approach 1:

The patent incorporates air voids and pores within the ceramic coating structure, which trap air (a thermal insulator) and reduce thermal effusivity. This allows the coating to maintain mechanical strength while achieving a warm thermal sensation similar to wood, resolving the contradiction between wear resistance and thermal comfort.

Inventive Principle:

Principle #31Porous materials

Solution Approach 2:

The patent creates a composite ceramic coating by incorporating organic fibers, air voids, and pores within the ceramic matrix. This composite structure combines the durability of ceramic with the thermal insulation properties of air and organic materials, achieving both wear resistance and pleasant thermal sensation.

Inventive Principle:

Principle #40Composite materials

2Temperature

If ceramic coatings are made more porous to reduce thermal conductivity, then thermal comfort is improved, but mechanical strength deteriorates

Engineering Contradiction:

Improvethermal conductivityVSAvoidmechanical strength

Core Design Contradiction:

TemperatureVSStrength

Solution Approach 1:

The patent distributes air voids and pores locally within specific regions of the ceramic coating rather than making the entire structure uniformly porous. This localized porosity reduces thermal conductivity in critical areas while maintaining structural integrity and mechanical strength in load-bearing regions.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent controls the size, distribution, and connectivity of air voids and pores as adjustable parameters. By optimizing these parameters, the coating achieves sufficient thermal insulation while maintaining adequate mechanical strength, resolving the trade-off between thermal comfort and structural durability.
