Folded Rectangular Rupture Disc for Simpler Edge Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of square rupture disks is complex due to the need for multiple parts and steps, including manufacturing and assembly of clip-on strips, which increases complexity and risk of damage during transport and assembly.
Innovation Solution
A simplified design featuring a fold in the edge region with parallel sheet parts and integrated shoulders, eliminating the need for clip-on strips and reducing forming energy, allowing for direct sheet metal formation and screw-based attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If mounting strips are used to form the edge of the rupture disc, then the edge can be formed separately, but the production complexity increases due to multiple manufacturing steps and assembly requirements
Solution Approach 1:
The patent merges the mounting strip function into the main sheet metal body by creating a folded edge region that forms both the sealing edge and the mounting structure. The first and second folded parts of the sheet metal create integrated mounting surfaces that eliminate the need for separate mounting strips, thereby reducing the number of parts and assembly steps while maintaining the edge formation function.
2Reliability
If mounting strips are used for the rupture disc edge, then the edge can be formed, but the risk of damage during transport and assembly increases
Solution Approach 1:
By integrating the mounting structure directly into the sheet metal through folding, the patent eliminates separate mounting strips that would be prone to damage during transport and assembly. The folded edge region creates a robust, monolithic structure that is inherently more reliable and less susceptible to damage while reducing overall device complexity.
3Productivity
If clip-on strips are manufactured and assembled, then the rupture disc can be formed, but the production time and complexity increase
Solution Approach 1:
The patent combines the edge formation and mounting structure creation into a single folding operation performed directly on the sheet metal. This eliminates the separate manufacturing and assembly steps required for clip-on strips, thereby increasing productivity by reducing the number of work steps and improving manufacturing efficiency while simplifying the device structure.
4Shape
If excessive forming energy is used to create features in the sheet metal, then the desired shape can be achieved, but undesirable deformation occurs
Solution Approach 1:
The patent segments the sheet metal into distinct functional regions including the folded edge region with first and second folded parts, and the central area with breaking lines. This segmentation allows forming operations to be localized to specific regions, reducing the total forming energy required while achieving the desired shape without causing undesirable deformation in other areas of the sheet metal.

AI summary
The invention relates to an angular, in particular rectangular, bursting disc (1) made of a sheet metal, with an edge region (11) with which the bursting disc (1) can be attached to an opening of a container or a pipe, and with a central region (12) with which the opening can be sealed up to a bursting pressure, and with predetermined breaking lines along which the bursting disc (1) tears open when the bursting pressure is reached, so that the central region (12) opens completely or partially, wherein the bursting disc (1) has a fold in the edge region (11) which has a first, folded part of the sheet metal and a second part of the sheet metal to which the folded part is parallel or predominantly parallel.
