Triple Insulating Glass Assembly for Thin Central Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assembling insulating glass, particularly triple glass with thin central plates, are inefficient, costly, and require complex apparatuses, posing challenges in spacer application and plate handling due to fragility and deformability.
Innovation Solution
A method involving a sequence of apparatuses that includes arranging a spacer on two glass plates, rotating a pre-assembled product by 180°, and coupling them to a central plate, using a standard press without a 'V' type, ensuring secure and efficient assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pre-assembly of one outer glass with the central glass is carried out and the other outer glass is rotated to face the spacer toward the central glass, then the assembly is functional, but it requires a particular type of 'V' press and increases device complexity
Solution Approach 1:
Instead of rotating the second outer glass plate to face the spacer toward the central glass, the invention inverts the approach by rotating the pre-assembled unit (first outer glass + central glass) so that its spacer faces the second outer glass. This eliminates the need for a complex 'V' press and standardizes the equipment required.
Solution Approach 2:
The invention applies the spacer to both outer glass plates before assembly, creating pre-assembled units with spacers already attached. This preliminary action simplifies the subsequent coupling process and eliminates the need for complex rotation mechanisms during final assembly.
2Use of energy by moving object
If the central plate is made thin to reduce weight and improve insulation, then energy efficiency improves, but the plate becomes fragile and deformable requiring special handling
Solution Approach 1:
The invention applies spacer material to the outer glass plates before assembly, creating a protective buffer that prevents direct contact and potential damage to the thin central plate during handling and assembly. This beforehand cushioning protects the fragile thin glass from deformation and breakage.
Solution Approach 2:
The invention changes the physical state of the spacer material by heating it to a viscosous state during assembly, allowing it to flow and conform to the glass surfaces without requiring mechanical pressure that could damage the thin central plate. This parameter change enables secure coupling without compromising plate integrity.
3Reliability
If a further station for applying spacer is arranged opposite to the first one, then spacer application is complete, but system complexity and cost increase
Solution Approach 1:
The invention merges the spacer application function into a single station that applies spacer material to both outer glass plates sequentially. This eliminates the need for a second opposite station and simplifies the spacer supply system, reducing both device complexity and operational complexity.
Solution Approach 2:
The single spacer application station is designed to be universal, capable of applying spacer material to either outer glass plate regardless of which one is being processed. This multi-functional design eliminates the need for specialized opposite stations and simplifies the overall system architecture.

AI summary
A method for making an insulating glass consisting of at least a first glass plate, a second glass plate, and a central glass plate involves arranging a spacer on the first glass plate, coupling the first glass plate to the central glass plate to make a pre-assembled product, rotating the pre-assembled product by an angle of around 180° with respect to a substantially vertical axis, and arranging a spacer on the second glass plate. The method further involves coupling the second glass plate to the central glass plate of the pre-assembled product to make the insulating glass.
