Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Glass composites experience deformation and surface distortion during processing, limiting their application due to brittleness and affecting appearance and optical performance.
Innovation Solution
A glass composite is formed by connecting first and second glass members with high light transmittance and strong bonding, allowing for complex shapes and structures with minimal bubbles or fantasy colors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple glass members are compounded to form a glass composite to overcome brittleness and achieve complex shapes, then the scope of application and structural complexity are improved, but deformation during processing occurs which deteriorates appearance quality and optical performance
Solution Approach 1:
The glass members undergo preliminary surface treatment including cleaning, activation, and roughening before compounding. This preliminary preparation ensures optimal bonding conditions and minimizes deformation during the compounding process, thereby maintaining appearance quality while achieving complex structures
Solution Approach 2:
The compounding process utilizes controlled parameter changes including temperature gradients (heating to bonding temperature and controlled cooling), pressure application, and atmospheric control. These parameter changes enable precise control of the bonding process to prevent deformation while achieving complex glass composite structures
2Device complexity
If multiple glass members are compounded to form a glass composite, then structural complexity and adaptability are improved, but bubbles and fantasy colors appear which deteriorate optical performance
Solution Approach 1:
The compounding process is conducted in a controlled inert or reducing atmosphere to prevent oxidation and chemical reactions that cause fantasy colors. This atmospheric control eliminates harmful chemical effects while enabling complex glass composite structures to be formed
Solution Approach 2:
The glass members undergo preliminary cleaning and surface treatment to remove contaminants, moisture, and organic residues before compounding. This preliminary preparation prevents bubble formation during bonding while allowing complex structures to be achieved
3Adaptability or versatility
If glass members are processed into complex shapes, then adaptability and scope of application are improved, but deformation occurs which deteriorates surface flatness and optical performance
Solution Approach 1:
The bonding process utilizes controlled temperature and pressure parameter changes to achieve complex shapes while maintaining surface flatness. The gradual heating and controlled cooling prevent thermal shock and deformation, enabling complex geometries with flat surfaces for optical applications

AI summary
A glass composite includes a first glass member and a second glass member. The first glass member and the second glass member are at least partially connected with each other at the surfaces; and the glass composite has a light transmittance not lower than 95% of the light transmittance of the one, with the lower light transmittance, of the first glass member and the second glass member.
