Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for cutting and separating laminated glass panes from a larger sheet are time-consuming, requiring numerous movements, repositionings, and rotations, which can be laborious and inefficient.
Innovation Solution
A method involving multiple parallel score lines along a fixed cutting axis, followed by rotation and perpendicular score lines to define rectangular panes, allowing for efficient cutting and separation of glass panes with reduced waste and fewer manual interventions, thereby minimizing the number of sheet movements and rotations.

Engineering Contradiction Analysis
1Productivity
If traditional sequential cutting method with multiple rotations and repositionings is used, then glass panes can be cut from the sheet, but the cutting process becomes time-consuming and laborious
Solution Approach 1:
The patent divides the cutting process into two distinct phases: a preliminary phase that creates a transverse portion with through-cuts, and a subsequent phase that performs multiple parallel score lines. This segmentation allows each phase to be optimized independently, with the preliminary phase preparing the sheet for efficient parallel cutting in the second phase, thereby reducing total cutting time.
Solution Approach 2:
The preliminary cutting phase performs through-cuts to create a transverse portion before the main parallel scoring phase. This preliminary action prepares the sheet by establishing reference lines and separating portions that will be processed in parallel, enabling the subsequent phase to operate more efficiently without requiring repeated rotations and repositionings.
2Ease of manufacture
If multiple rotations and repositionings of the sheet are performed, then cuts in different regions can be made, but the number of manual interventions increases
Solution Approach 1:
Instead of rotating the sheet to bring different regions to the cutting position, the patent inverts the approach by keeping the sheet in a fixed position and moving the cutting tool along a fixed axis to perform multiple parallel score lines. This inversion eliminates the need for repeated sheet rotations and repositionings, significantly reducing manual handling complexity.
Solution Approach 2:
The fixed cutting axis and standardized score line procedure serve multiple functions: they cut glass panes of various dimensions, create separation lines, and establish reference marks all through the same operational mechanism. This multi-functionality eliminates the need for different cutting configurations or repeated repositioning operations.
3Adaptability or versatility
If sequential cutting with repeated repositioning is used, then glass panes of various dimensions can be obtained, but the process efficiency decreases
Solution Approach 1:
The patent introduces dynamic parallel processing by performing multiple score lines simultaneously in the second phase, rather than sequential cutting. The cutting tool moves along a fixed axis creating multiple parallel lines in one continuous operation, dynamically increasing productivity while maintaining the ability to produce glass panes of various dimensions by adjusting the scoring pattern.

AI summary
A method for providing laminated glass panes starting from a sheet which comprises a cutting and separation phase; the cutting and separation phase comprises: - a preliminary step for the cutting and separation of the transverse portion, in which the sheet (100) is cut from one edge (101) to an opposite edge (102) so as to obtain a transverse portion (10); - a first scoring step, in which multiple first mutually parallel score lines (11, 12, 13) are performed, translating the transverse portion (10) with respect to the fixed cutting axis (Y) following each one of the first score lines (11, 12, 13), followed by - a second rotation step, in which the transverse portion (10) is rotated through 90° with respect to the cutting axis (Y), followed by - a third step of scoring and separation, in which multiple second score lines (21, 22, 23) are performed which are parallel to each other and perpendicular to the first score lines (11, 12, 13), translating the transverse portion (10) with respect to the fixed cutting axis (Y) following each one of the second score lines (21, 22, 23); each one of the second score lines (21, 22, 23) intersecting at least one of the first score lines (11, 12, 13) so as to define a plurality of rectangular panes (1, 2, 3, 4); following each one of the second score lines (21, 22, 23), an outermost rectangular pane (1, 2, 3, 4) being separated from a corresponding waste (91, 92, 93) which is not separated from the rectangular pane (1, 2, 3, 4).
