Glass Panel Assembly Cutting Along the Seal Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to cut off glass substrates along a plane aligned with a seal member without causing damage, especially when one or both substrates are relatively thick.
Innovation Solution
A method involving an arrangement step, bonding step, and cutting step, where glass substrates are bonded via a seal member and cut off along a plane where the seal member remains on the cross-section sides, using a first and second cutting step to ensure precise alignment and ease of cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If glass substrates are cut off along a plane aligned with the seal member from one side, then the cutting process is simplified, but damage occurs to the glass substrates especially when they are relatively thick
Solution Approach 1:
The cutting process is divided into two separate steps: first cutting the first glass substrate from its first surface, then cutting the second glass substrate from its second surface. This segmentation allows each substrate to be cut independently with appropriate cutting parameters, preventing damage that would occur if both were cut simultaneously from one side, while still achieving the overall goal of separating the bonded substrates along the seal member alignment.
2Productivity
If glass substrates of varying thicknesses are cut from one side, then the process is faster, but alignment precision along the seal member deteriorates
Solution Approach 1:
Instead of cutting both substrates from the same side (first surface), the method inverts the approach by cutting the first substrate from its first surface and the second substrate from its second surface. This inversion allows each substrate to be cut from its optimal surface, maintaining high alignment precision along the seal member regardless of thickness variations, while still achieving efficient productivity.
3Loss of time
If a single cutting step is used to cut both substrates, then manufacturing time is reduced, but the complexity of the cutting operation increases
Solution Approach 1:
The single complex cutting operation is segmented into two simpler cutting steps: first cutting the first substrate from its first surface, then cutting the second substrate from its second surface. This segmentation reduces the complexity of each individual cutting operation while maintaining overall manufacturing efficiency, as each step can be performed with standard cutting equipment and procedures without requiring complex multi-axis coordination.

AI summary
A arrangement step includes arranging a first glass substrate and a second glass substrate to make the first and second glass substrates face each other with a seal member interposed between themselves. A bonding step includes bonding the first and second glass substrates via the seal member. A cutting step includes cutting off the first and second glass substrates along the same line when viewed in a facing direction in which the first and second glass substrates bonded together face each other and along the seal member. A cutting step is the step of forming multiple sets of the first and second glass substrates divided by cutting off the first and second glass substrates along a plane where the seal member remains on respective sides of cross sections of the first and second glass substrates divided.
