Folded-Edge Rectangular Rupture Disk for Simpler Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of angular rupture disks is overly complex due to the need for multiple manufacturing steps and the use of additional parts such as add-on strips, which complicates assembly and increases the risk of parts being lost or damaged during transportation and assembly.
Innovation Solution
The rupture disk design incorporates a fold-over of sheet metal to eliminate the need for add-on strips, allowing for simpler transformation and assembly, with holes for screwing into place and strategically placed shoulder areas to reduce deformation and complexity, while maintaining functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If add-on strips are used to form the edge region, then the rupture disk can be manufactured with separate components, but the production complexity increases due to multiple manufacturing steps and assembly requirements
Solution Approach 1:
The patent merges the edge region formation into the sheet metal itself by folding over the edges, eliminating the need for separate add-on strips. This combines multiple previously separate components (sheet metal and add-on strips) into a single integrated structure, reducing the number of parts from 2 to 1 and simplifying the manufacturing process.
Solution Approach 2:
The patent extracts and eliminates the add-on strips from the design, keeping only the essential sheet metal component. By removing the unnecessary add-on strips and their associated manufacturing and assembly steps, the design achieves simplicity while maintaining functionality through the folded-over edge structure.
2Reliability
If add-on strips are used, then the edge region can be formed, but the risk of part loss or damage during transportation and assembly increases
Solution Approach 1:
By integrating the edge region directly into the sheet metal through folding, the patent eliminates separate components that could be lost or damaged. The folded-over edges become an inherent part of the sheet metal structure, ensuring part retention and reliability during transportation and assembly.
3Productivity
If multiple components are used, then the rupture disk can be assembled, but additional assembly steps and transport protection are required
Solution Approach 1:
The patent combines the sheet metal and edge region into a single integrated component through folding, eliminating the need for separate assembly steps. This single-component design allows the rupture disk to be produced and assembled at a single workstation without additional parts or transport protection, significantly improving productivity.

AI summary
A rectangular rupture disk comprising sheet metal includes an edge region with which the rupture disk is fastenable to an opening of a container or of a conduit. In the edge region, the rupture disk has a fold-over including a first folded over part of the sheet metal and a second part of the sheet metal to which the first folded over part is parallel or predominantly parallel. The rupture disk further includes a central region with which the opening is sealable until the container or conduit reaches a bursting pressure, and predetermined breaking lines along which the rupture disk ruptures to at least partially open the central region in response to the container or conduit reaching the bursting pressure.
