Cut-out Laminated Sheet Protruding Section Shearing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for preparing cut-out laminated sheets face difficulties in removing protection sheets after shearing, especially with brittle materials, as the sheets become identical in shape, leading to time-consuming and potentially damaging removal processes.
Innovation Solution
A two-step shearing process is employed to create a laminated sheet with a protruding section, allowing for easy removal of the protection sheet by applying shear forces in opposite directions with a clearance, leaving only the protection sheet in the protruding section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a shearing process is applied to the laminated sheet, then the base sheet can be prepared in a specific shape, but the protection sheet becomes difficult to remove because both sheets have identical shapes
Solution Approach 1:
The patent applies segmentation by creating a protruding section that separates the protection sheet from the base sheet. The shearing process cuts the protection sheet beyond the base sheet edges, creating distinct segments where the protection sheet extends outward. This segmentation allows the protection sheet to be removed independently without affecting the base sheet, resolving the difficulty caused by identical shapes.
2Productivity
If protection sheets are removed after shearing, then the base sheet can be applied to the final product, but brittle sheets may be damaged due to cracks formed during removal
Solution Approach 1:
The patent applies preliminary action by performing the shearing process that creates the protruding section before the protection sheet removal. This preliminary shaping establishes a clear separation geometry that facilitates easy and damage-free removal. The protruding section is created in advance, so when the protection sheet is removed, no additional stress or cracking occurs on the brittle base sheet.
3Productivity
If protection sheets are removed after shearing, then the base sheet can be used, but the removal process is time-consuming and reduces overall productivity
Solution Approach 1:
The protruding section created by the shearing process segments the protection sheet from the base sheet, establishing a clear separation line. This segmentation enables rapid removal of the protection sheet without requiring time-consuming manual operations. The protection sheet can be quickly peeled or cut away from the protruding section, significantly reducing removal time and improving overall productivity.

AI summary
A cut-out laminated sheet can be prepared by laminating a protection sheet on a base sheet, followed by a simple two-step shearing process. The cut-out laminated sheet thus prepared features a protruding section that helps improving productivity by making the removal of the protection sheet easy; and thus, can be effectively used in a wide range of industrial applications such as a brittle sheet and a flexible sheet.
