Solution Overview

Problem

Existing methods for producing full-body marbled-patterned glass mosaics result in patterns that do not faithfully resemble natural stones, lack ideal texture, and have inadequate corrosion and stain resistance, leading to issues with durability and appearance over time.

Innovation Solution

A method involving mixing cullet with additives and using a glass powder as a low-temperature flux to enhance particle uniformity and distribution, combined with a multi-layered colorant mixture, which improves the glassy texture and resistance properties, and simulates the pattern and texture of natural marble.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If inkjet printing is performed on the surface of the green body of mosaic glass followed by high-temperature firing, then patterns are formed on the glass mosaic, but the patterns appear to float on the surface, do not appear three-dimensioned, and do not faithfully resemble natural stones

Engineering Contradiction:
Improvepattern fidelityVSAvoidthree-dimensional appearance
Core Design Contradiction:
Manufacturing precisionVSShape

Solution Approach 1:

The patent applies inkjet printing on the green body surface before low-temperature glaze application, embedding the pattern within the glaze layer rather than leaving it floating on the surface. This preliminary action ensures the pattern is integrated into the structure before final firing, creating a more three-dimensional appearance that resembles natural stone.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent combines multiple materials including green body glass, low-temperature glaze, and inkjet-printed pattern materials to create a composite structure. The pattern is formed by the interaction of these materials during low-temperature firing, producing a multi-layered composite that achieves both fidelity to natural stone and three-dimensional appearance.

Inventive Principle:
Principle #40Composite materials

2Ease of manufacture

If low-temperature glaze is sprayed onto the surface of green body of mosaic glass followed by low-temperature firing, then the glass mosaic acquires color and decorative properties, but the texture is not ideal and the pattern transition section does not appear natural enough

Engineering Contradiction:
Improvelow-temperature processingVSAvoidpattern transition naturalness
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent applies different materials and processing conditions to different regions of the glass mosaic. The inkjet-printed pattern areas receive different glaze composition and firing treatment compared to the background areas, creating local variations in texture and color transition that mimic natural stone patterns while maintaining overall low-temperature processing.

Inventive Principle:
Principle #3Local quality

3Productivity

If mold is used to distribute materials for full-body marbled-patterned mosaic, then material distribution is achieved, but the pattern is repetitive and the texture is not ideal

Engineering Contradiction:
Improveproduction efficiencyVSAvoidpattern diversity
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent replaces the mechanical mold distribution system with an inkjet printing system that deposits pattern materials precisely on the green body surface. This substitution eliminates the repetitive patterns caused by mold cavities while maintaining efficient material distribution through digitally controlled inkjet heads, enabling unique patterns for each tile.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Ease of manufacture

If additives including binder, whitening agent, and anti-settling agent are used in mosaic production, then the mosaic can be formed, but the corrosion resistance and stain resistance are insufficient, and the mosaic is susceptible to rain erosion and weathering

Engineering Contradiction:
Improvemosaic formabilityVSAvoidcorrosion and stain resistance
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent changes the chemical composition parameters of the glaze layer, using low-temperature glaze with specific compositional ratios that provide both formability during firing and enhanced corrosion/stain resistance after firing. The glaze composition is optimized to create a dense, non-porous surface layer that protects the underlying mosaic from weathering while allowing the mosaic to be formed at lower temperatures.

Inventive Principle:
Principle #35Parameter changes
