Phase-Separated Glass Manufacturing via Molten State Homogenization
Solution Overview
Problem
The production of phase-separated glass for electronic device chassis is inefficient and costly due to the need for additional thermal treatment after shaping, leading to potential temperature unevenness and heterogeneity in shielding properties and hue.
Innovation Solution
A method involving melting, phase separation, and shaping of glass without subsequent thermal treatment, where phases are separated at a high temperature, allowing for homogeneous phase separation and reduced production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glass is subjected to conventional phase separation treatment after melting and shaping, then shielding properties are achieved, but production efficiency decreases and cost increases due to additional thermal treatment steps
Solution Approach 1:
The patent applies preliminary action by incorporating phase separation treatment during the melting process itself, before the glass is shaped. This means the phase separation is performed in advance while the glass is in molten state, eliminating the need for subsequent thermal treatment after shaping. The glass composition is designed to undergo phase separation at melting temperatures, so the shielding properties are established before the glass is formed into its final shape, thereby improving production efficiency while maintaining reliable shielding performance.
2Reliability
If glass undergoes conventional phase separation thermal treatment after shaping, then phases are separated, but temperature unevenness causes heterogeneity in shielding properties and hue
Solution Approach 1:
The patent applies parameter changes by utilizing the high temperature molten glass state during melting to induce phase separation, rather than using conventional lower temperature thermal treatment after shaping. The phase separation is achieved by controlling the temperature parameters during melting and holding the glass at appropriate temperatures to allow phase separation to occur uniformly throughout the molten glass before shaping. This temperature parameter change ensures homogeneous phase distribution and consistent shielding properties without the temperature unevenness problems of post-shaping treatment.
3Reliability
If coated film is formed on glass to provide shielding properties, then light blocking is achieved, but the number of steps and cost increase
Solution Approach 1:
The patent applies merging by combining the phase separation process with the glass melting and shaping process into a single integrated operation. Instead of separately forming a coated film on the glass surface to provide shielding properties, the shielding functionality is merged into the bulk glass structure through phase separation during melting. This eliminates the need for separate coating steps and reduces the overall number of manufacturing steps while achieving the same shielding effect.
