Partial Cutting Multilayer Vibration Damping Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for creating vibration damping plates, such as milling grooves in steel layers, are complex and costly, necessitating a simpler and more convenient approach for forming cutting lines in multilayer plate structures.
Innovation Solution
A punching-type method is used to make partial cuts of narrow width through a multilayer laminate structure, with measures to prevent lateral displacement and curling of the rigid layers during cutting, allowing the cut to extend through the rigid and non-rigid layers without removing sheet material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If milling grooves in steel layers is used to create vibration damping plates, then the vibration damping properties are achieved, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent changes the manufacturing method from milling (subtractive process) to punching (formative process), altering the production parameters to achieve the same functional result with simpler equipment and lower cost while maintaining the groove structure necessary for vibration damping
Solution Approach 2:
The patent replaces the complex milling mechanical system with a simpler punching mechanism, substituting a high-precision cutting process with a more straightforward forming process that achieves the same structural outcome with reduced manufacturing complexity
2Ease of manufacture
If punching is used to create cuts in multilayer laminate structures, then manufacturing simplicity and cost are reduced, but lateral displacement and curling of rigid layers occur
Solution Approach 1:
The patent applies preliminary counter-actions by incorporating support elements and positioning features that prevent lateral displacement and curling before they can occur during the punching process, thereby maintaining layer alignment precision while using the simple punching method
Solution Approach 2:
The patent introduces intermediary support structures and positioning elements that act as mediators between the punching force and the laminate layers, preventing unwanted lateral displacement and curling while allowing the simple punching process to proceed
3Loss of substance
If punching is used to create narrow cuts through multilayer structures, then material removal is minimized, but preventing lateral displacement requires additional measures
Solution Approach 1:
The patent segments the punching tool into distinct functional components (cutting elements, support elements, positioning features) that work together to achieve narrow cuts with minimal material removal while preventing lateral displacement, distributing the functionality across multiple specialized elements

AI summary
A cutting line partially through a multilayer plate structure (1) comprising at least one rigid layer (6, 7) attached to a non-rigid layer (5) is formed by punching in one operation a cutting edge (15) through at least the rigid layer (6) but leaving at least one layer (7) of the multilayer plate structure (1) uncut. During the cutting operation, the rigid layer is gripped by lateral position retaining means (16) to prevent lateral movement of the rigid layer.
