Segmented Screen Rod Tensioning System for Foldable Vibratory Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibratory screen apparatuses, such as those with hook-strip and pre-tensioned screens, are complex to assemble, prone to damage, and difficult to handle and transport due to their rigid and bulky design, leading to inefficiencies in material separation and potential contamination issues.
Innovation Solution
A screen rod tensioning system that allows the screen to be rolled and folded, utilizing a profile with a circular or elliptical cross-section that can be inserted into a rod for reduced size transport and a segmented design with living hinges for easy assembly and disassembly, eliminating the need for sectional screens and reducing handling difficulties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional hook-strip or pre-tensioned screens are used, then the screen can maintain structural integrity during operation, but the screen becomes complex to assemble, difficult to handle and transport, and prone to damage
Solution Approach 1:
The screen is divided into multiple segments that can be assembled together, allowing for easier handling and transport while maintaining structural integrity during operation. Each segment can be independently managed and replaced if needed.
Solution Approach 2:
The screen segments are designed to nest within each other when not in use, creating a compact configuration that is easy to store and transport. The nested structure reduces the overall volume and handling difficulty while maintaining full functionality when deployed.
2Strength
If rigid and bulky screen designs are used, then the screen maintains strength and durability, but the screen becomes difficult to handle, transport and store
Solution Approach 1:
The screen transitions from a static rigid structure to a dynamic system where segments can be collapsed and extended. The screen can be collapsed into a compact form for easy transport and storage, then deployed to its full operational size and rigidity when needed, providing both ease of handling and structural strength.
Solution Approach 2:
The screen utilizes flexible elements that can be collapsed into a compact form factor for easy transport, then rigidify when deployed. This flexibility allows the screen to be handled and stored in compact configurations while maintaining full structural integrity during operation.
3Productivity
If conventional screen designs are used, then the screen can perform separation functions, but the screen requires significant space for installation and is difficult to replace
Solution Approach 1:
The screen is segmented into multiple sections that can be independently installed and replaced. This segmentation allows for modular installation that requires less overall space and enables individual segments to be replaced without removing the entire screen assembly, improving maintenance efficiency.
Solution Approach 2:
The screen can be collapsed into a compact configuration for storage and transport, then deployed to its full operational size when installed. This dynamic capability reduces the space required for installation and makes the screen easier to replace, as it can be collapsed for handling during maintenance operations.

AI summary
An apparatus, a system and a method for reinforcing a screen has a screen rod assembly extending from a first end to a second end. The screen rod assembly encloses an interior. A spring-loaded plunger is located in the interior and adjusts the length of the screen rod assembly. A ball joint is on the screen rod and defines sections of the screen rod assembly that bend around the ball joint to reduce the length of the screen rod. A sleeve extends from a screen with segments separated by a fold line extending along a width of the screen. The sleeve receives the screen rod assembly to reinforce the screen. In an embodiment, a screen pinch assembly is defined where the sleeve engages a retention clasp of a screen tensioning system that receives the screen. The screen pinch assembly holds the screen in place.
