Bursting Disc Angle Limiter Plate for Predictable Flame Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for limiting the opening angle of bursting discs are prone to damage from environmental influences, leading to impaired functionality over time, and have not been widely adopted in practice.
Innovation Solution
A device with a plate made of stainless steel, featuring distinct areas that allow for controlled bending and attachment to bursting discs, limits the opening angle to less than 90° while resisting deformation, ensuring the pressure wave and/or flame is directed predictably.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device with flexible material triangular pieces is used to limit the opening angle, then the opening angle can be limited, but the device is exposed to environmental influences and prone to damage over time
Solution Approach 1:
The patent changes the material parameter from flexible material to elastically deformable metal plate, which maintains the angle limiting function while providing resistance to environmental damage and long-term reliability
Solution Approach 2:
The device combines different areas of the metal plate with distinct properties: a first area that can be elastically deformed by the bursting disc and second areas that remain rigid for attachment purposes, creating a composite structure with optimized properties for each function
2Object-generated harmful factors
If the bursting disc is allowed to pivot up to 180°, then pressure relief is maximized, but the pressure wave and flame cannot be directed in a preferred direction
Solution Approach 1:
The patent changes the opening angle parameter from the conventional up to 180° to a limited angle less than 90°, achieved through the elastically deformable first area of the metal plate that resists further opening beyond the limited angle, thereby directing the pressure wave and flame in a preferred direction
3Ease of operation
If the first area of the plate is made highly flexible to allow bursting disc movement, then the opening angle can be limited, but the plate may deform excessively and fail
Solution Approach 1:
The patent applies local quality by creating different areas in the metal plate with different mechanical properties: the first area is designed to be elastically deformable to allow controlled bending, while the second areas maintain high strength and rigidity for attachment, preventing excessive deformation and failure
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively protects the device from environmental damage and allows for flexible installation and design, ensuring reliable pressure wave and flame directionality without compromising the bursting disc's functionality.
Implementation Method 1
the central area of the rupture disc presses on the at least one first area of the plate and bends it or arches it out

AI summary
The device has a plate, particularly a sheet metal blank, having a region (11) inclined perpendicular to the plane of the plate under the action of force. The plate on opposite sides of the region comprises another region, particularly flanges, with which the plate is fastened, where a third region (13) is disposed between the former region and the latter region. The former region has a recess or a notch. An independent claim is included for a bursting disk assembly.
