Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current glass screen printing techniques result in non-vivid patterns, poor transparency, unsecured layers, and inadequate abrasive resistance, making them unsuitable for light-emitting tiles and failing to provide a raised and sunken three-dimensional effect.
Innovation Solution
A glass pattern printing process involving screen printing a semi-transparent ground color, additional colors, and layers of transparent high-temperature and frosted glazes, followed by tempering and sintering to create a compact, wear-resistant, acid-resistant, and alkali-resistant coating with raised and sunken three-dimensional grains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If current glass screen printing is used, then the printing process is simple, but the patterns are not vivid and hues are not rich
Solution Approach 1:
The patent divides the printing process into multiple stages: first printing a ground color layer, then printing additional color layers, and finally applying a transparent glaze layer. This segmentation allows each layer to contribute specific properties - the ground color provides base hues, additional layers add complexity and vividness, and the glaze layer enhances transparency and durability, collectively resolving the contradiction between process simplicity and pattern quality.
Solution Approach 2:
The patent uses composite material structures with multiple glaze layers containing different colorants and transparent glaze layers. This composite approach allows the combination of various materials' properties - color richness from pigmented layers and transparency from clear glaze layers - achieving both vivid patterns and rich hues without requiring a single complex material.
2Device complexity
If current glass screen printing is used, then the printing process is straightforward, but transparency is poor
Solution Approach 1:
The patent separates the functional requirements into distinct layers: color-providing layers and transparency-providing layers. The transparent glaze layer is applied over the colored layers, allowing light to pass through while the underlying layers provide color. This segmentation resolves the contradiction by assigning transparency function to a dedicated layer rather than requiring the entire process to be complex.
Solution Approach 2:
Different layers are assigned different local qualities - colored layers provide pigmentation while transparent glaze layers provide transparency. This local differentiation allows each layer to optimize its specific function without compromising the other, achieving both good transparency and vivid patterns through the layered structure.
3Device complexity
If current glass screen printing is used, then the application is simple, but the pattern layers are unsecured and susceptible to wear
Solution Approach 1:
The patent applies a transparent glaze layer over the colored pattern layers before final firing. This preliminary protective layer is then sintered at high temperature (600-700°C) to form a durable, wear-resistant coating that secures the underlying pattern layers. The preliminary application of this protective layer resolves the contradiction between simple application and durable results.
Solution Approach 2:
The patent creates a composite structure where a transparent glaze layer is bonded to colored pattern layers through high-temperature sintering. This composite material structure combines the aesthetic properties of the colored layers with the protective properties of the glaze layer, achieving both simple application process and high abrasive resistance through the bonded composite structure.
4Device complexity
If current glass screen printing is used, then the process is straightforward, but three-dimensional effect and non-skid properties are poor
Solution Approach 1:
The patent introduces raised and sunken three-dimensional grains into the transparent frosted glaze layer, creating a porous or textured surface structure. This texture provides both visual three-dimensional effect and physical non-skid properties. The incorporation of this textured structure into the glaze layer resolves the contradiction between straightforward process and effective three-dimensional surface characteristics.

Function Achieved in This Case
The process ensures vivid patterns, rich hues, and a strong texture, making the glass surface wear-resistant, acid-resistant, alkali-resistant, and transparent, suitable for light-emitting tiles with enhanced durability and performance compared to conventional methods.
Implementation Method 1
The glass pattern printing process may provide the step of sintering the glass to form a compact coating. The glass may be sintered at a temperature that may be between approximately six hundred to seven hundred degrees Celsius.
Implementation Method 2
The glass pattern printing process may provide the step of tempering the glass with the layer of the transparent and high-temperature glaze, and the layer of the transparent and high-temperature glaze may be screen-printed in a tempering furnace.
