Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing double-sided glass-based coatings with adhesion-reducing properties are economically and technically disadvantageous due to a narrow operating window for crystallization, limiting design configurations and requiring complex thermal prestressing without contact, which is difficult to integrate and costly.
Innovation Solution
A method involving a substrate with a first layer-forming material containing glass powder and structure-forming particles that produce elevations, allowing the second layer to be applied without adhering to the underlay, utilizing particles with a melting temperature greater than the glass powder for anti-sticking properties and achieving high-grade glass-based layers on both sides with controlled heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glass-based coatings with adhesion-reducing properties are produced using conventional crystallization methods, then anti-sticking properties are achieved, but the operating window is narrow and design configurations are limited
Solution Approach 1:
The patent changes the fundamental parameter of anti-sticking mechanism from crystallization-based to elevation-based. By using structure-forming particles that create surface elevations upon heating, the method eliminates the narrow crystallization operating window and enables broader design flexibility while maintaining reliable anti-sticking properties.
Solution Approach 2:
The invention utilizes the phase transition of glass powder during heating to form a matrix that incorporates structure-forming particles. This phase change enables the creation of stable elevations that provide anti-sticking properties without requiring precise crystallization control, thereby expanding design possibilities.
2Reliability
If thermal prestressing without contact is used to produce double-sided coatings, then adhesion-reducing properties are achieved, but the process becomes complex and costly
Solution Approach 1:
The patent extracts the anti-sticking function from the complex thermal prestressing process and integrates it directly into the coating material itself. By incorporating structure-forming particles that create elevations during normal heating, the method eliminates the need for separate contactless thermal prestressing equipment while maintaining adhesion-reducing properties.
Solution Approach 2:
The coating material performs the anti-sticking function autonomously through its own composition and heating behavior. The structure-forming particles self-organize into elevations during the heating process, providing anti-sticking properties without requiring external intervention or complex equipment, thereby simplifying the overall process.
3Reliability
If structure-forming particles with melting temperature greater than glass powder are used, then anti-sticking properties are achieved, but the manufacturing process requires controlled heating
Solution Approach 1:
The patent performs preliminary action by selecting structure-forming particles with specific melting temperatures higher than the glass powder before the heating process begins. This pre-selection ensures that during heating, the glass powder melts and forms a matrix while the particles remain intact to create elevations, providing anti-sticking properties without requiring complex real-time heating control.
