Filter Plate Snap-In Attachment for High-Pressure Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastenings of attachment parts on filter plates in filter presses, such as screws, can become blocked under high pressures, leading to impaired functionality and loss of connection elements, making detachment and reassembly difficult.
Innovation Solution
A detachable ball-type snap-in connection using a ball pin and coupling, which relies on elastic forces to securely fasten and easily release attachment parts like distributor rings, support rings, and membranes, ensuring reliable and durable attachment despite high operational pressures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional screw fastenings are used to attach attachment parts to filter plates, then the connection is secure under high pressure, but the fastenings become blocked and lose functionality over time, requiring disassembly and reassembly
Solution Approach 1:
The fastening system is segmented into separate components: a fastening element with a ball-shaped head and a receptacle with a corresponding ball-shaped recess. This segmentation allows the attachment part to be quickly detached and reattached without threading operations, resolving the contradiction between secure fastening and ease of detachment.
Solution Approach 2:
The threaded mechanical fastening system is replaced with a ball-and-receptacle mechanical interface that uses simple insertion and engagement rather than screw threading. This substitution eliminates the blocking issue while maintaining secure attachment under pressure, improving both reliability and ease of operation.
2Strength
If screws are used to fasten attachment parts, then the connection is strong, but connection elements are lost during disassembly and reassembly
Solution Approach 1:
The fastening system uses segmented components where the attachment part itself incorporates the ball-shaped engagement feature. This integration eliminates separate connection elements that could be lost, while the ball-and-receptacle interface maintains strong connection strength during operation.
Solution Approach 2:
The attachment part serves its own fastening function by incorporating the ball-shaped feature directly into its structure. This self-service approach eliminates the need for separate screws or fasteners that could be lost, reducing connection element loss while maintaining connection strength.
3Ease of operation
If detachable fastenings are used to allow easy removal of attachment parts, then detachment is easy, but the connection may become loose under high operational pressures
Solution Approach 1:
The fastening system is segmented into a ball-shaped fastening element and a receptacle with a ball-shaped recess, allowing easy detachment while the precise geometric fit ensures stable connection under pressure. The segmentation enables simple removal without compromising connection reliability during operation.
Solution Approach 2:
The ball-shaped fastening element and corresponding spherical recess create a geometric interface that naturally resists dislodgement under pressure while allowing easy insertion and removal. The curved spherical geometry provides both detachment ease and connection stability simultaneously.
