Glass Sheet Impregnation for Bending Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass sheet manufacturing processes struggle to create durable glass sheets, particularly when handling bending stresses, as they often lack sufficient reinforcement in specific regions.
Innovation Solution
A method involving the impregnation of a glass sheet with a filler material in a liquid state, followed by solidification, to form a glass/filler composite region. This composite region enhances the durability of the glass sheet by filling voids between glass soot particles with the filler material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If glass soot particles are deposited on a rotating drum to form a glass soot sheet, then the glass sheet can be formed, but the glass sheet lacks sufficient durability under bending stresses
Solution Approach 1:
The patent applies composite materials by combining glass soot particles with a binder material to form a glass/filler composite region. This composite structure provides both the formability of glass soot and the mechanical strength of the binder, resolving the contradiction between ease of manufacture and durability under bending stresses.
Solution Approach 2:
The patent applies local quality by creating a specific glass/filler composite region at the leading edge of the glass sheet where bending stresses are most severe during handling. This localized reinforcement provides durability exactly where needed without compromising the overall manufacturability of the glass sheet.
2Reliability
If the glass sheet is reinforced to improve durability, then handling becomes easier, but the manufacturing process becomes more complex
Solution Approach 1:
The patent applies preliminary action by incorporating the binder material into the glass soot particles during the deposition process itself, rather than adding reinforcement later. This preliminary incorporation ensures durability from the start and simplifies the overall manufacturing process by eliminating separate reinforcement steps.
Solution Approach 2:
The patent merges the formation of glass soot particles with the incorporation of binder material into a single integrated process. The binder is applied to the rotating drum simultaneously with glass soot deposition, combining two functions into one operation and reducing manufacturing complexity.
