Pivotable Screen Connector Seal for Screening Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screening arrangements face challenges in connecting screening elements without material spillage, as current solutions often require significant effort and result in leakage between adjacent screens.
Innovation Solution
A screening arrangement featuring pivotable elements that pivot between positions to form a seal between screen connectors, preventing larger particles from passing through and minimizing material spillage, with side walls acting as connection points and guides to prevent material from sliding off.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a fixed beam with ridges is used to connect screening elements, then the connection structure is simple and stable, but significant effort is required to overcome the stiffness of screening elements for connection
Solution Approach 1:
The patent employs a movable connection point that can shift position along the screening element rather than being fixed. This dynamic connection mechanism allows the rigid screening element to be easily connected without requiring significant force to overcome stiffness, while still providing stable connection when in place
2Ease of operation
If movable connection points are used to facilitate easy connection, then connection effort is reduced, but significant leakage of material occurs between adjacent screening elements
Solution Approach 1:
The patent introduces a movable connection point as an intermediary component between adjacent screening elements. This connection point serves as a mediator that maintains close proximity between screens while allowing easy connection, and incorporates features to prevent material leakage in the gap between screens
3Stability of the object's composition
If screening elements are tensioned longitudinally with fixed connection points in the middle region, then the screening arrangement structure is stable, but the connection points are difficult to access and connect to
Solution Approach 1:
The patent moves from fixed connection points to a movable connection point system that can be positioned at convenient locations along the screening elements. This dynamic positioning maintains the stability of the overall screening arrangement while significantly improving accessibility for connection operations

AI summary
A screening arrangement including two side walls, each having an inward facing side and an outward facing side, and a screen holder arrangement extending between the inward facing sides of the side walls for use in connecting a first and a second screening element. The screen holder arrangement includes a first screen connector and a second screen connector. The first screen connector includes a pivotable element arranged to pivot about an axis that is parallel with a longitudinal extension of the first screen connector. The pivotable element includes a connection portion arranged to hold one end of the first screening element. The pivotable element is arranged to pivot between a first position and a second position, where the pivotable element is arranged such that when it is in the second position and a screen is connected to the pivotable element, particles larger than a predetermined size are prevented from passing between the first and second screen connectors.
