Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the glass base material is immersed in a potassium hydrogencarbonate aqueous solution and heated to 30-90°C for an extended period, then a net-like structure layer can be produced on the surface, but the treatment time becomes excessively long (close to 24 hours) and the layer depth is insufficient
Solution Approach 1:
The invention changes the physical parameters of the treatment environment by applying pressure (1-10 atm) in addition to temperature control. This pressure parameter modification accelerates the chemical reaction rate and mass transport, enabling sufficient layer depth to be achieved in 1-10 hours instead of 24 hours
Solution Approach 2:
The invention employs periodic stirring of the treatment solution to maintain fresh reagent contact with the glass surface and remove reaction products. This periodic renewal of the treatment environment sustains high reaction efficiency throughout the treatment period, preventing saturation and enabling deeper layer formation within shorter time
2Manufacturing precision
If only heating the treatment solution is used, then the net-like structure layer can be formed, but uniform surface treatment is difficult and surface unevenness occurs
Solution Approach 1:
The invention implements continuous stirring of the treatment solution throughout the treatment process. This continuous action ensures uniform distribution of reagents and consistent contact with all areas of the glass surface, preventing localized saturation and ensuring uniform etching depth and surface morphology across the entire substrate
3Reliability
If a multilayer film of dielectric is laminated on the glass base material, then the antireflection function is provided, but the heat-resistant property, chemical-resistant property, and wear-resistant property are limited
Solution Approach 1:
The invention replaces the mechanical lamination process with a chemical etching process that directly modifies the glass surface. Instead of adding a separate dielectric layer through lamination, the net-like structure is formed by controlled chemical removal of glass material, creating inherent functional properties through surface topology rather than external coating
Solution Approach 2:
The invention creates a composite surface structure where the net-like patterned glass surface combines multiple functions (antireflection, hydrophobicity, soil resistance) in a single integrated structure. The alternating ridges and valleys of the net-like pattern provide different optical and surface properties without requiring separate material layers
