Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screening panels for vibratory machines require labor-intensive installation, lack tensioning capabilities, leading to reduced functionality and increased clogging, especially with untensioned wires and woven wire meshes.
Innovation Solution
A modular screening panel with pre-tensioned wires secured to a frame, allowing independent vibration and self-cleaning properties, which can be easily installed without additional tensioning, using a dual carriage device for manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional hooked screen panels are used, then the screening function is provided, but the installation process is time-consuming and laborious requiring multiple installers
Solution Approach 1:
The screen panel is divided into modular sections with standardized mounting features. The frame is segmented into discrete components that can be independently assembled, allowing the screen to be installed in modular units rather than as a single large panel, reducing installation complexity and time
Solution Approach 2:
The wires are pre-tensioned and pre-assembled into the frame structure during manufacturing. The mounting features are pre-positioned on the frame, eliminating the need for field tensioning and alignment operations that previously required multiple installers and extensive time
2Ease of operation
If modular screens with fixed size and shape are used, then installation is simplified to single installer with minimal training, but the screen material cannot be adjusted
Solution Approach 1:
The screen panel incorporates adjustable wire tensioning mechanisms that allow the tension level to be modified after installation. The frame includes adjustment features that enable the screen material properties to be changed to match different aggregate types and screening requirements, providing adaptability while maintaining modular installation benefits
3Ease of manufacture
If untensioned wires are used in modular screens, then manufacturing is simplified, but the wires lack rigidity requiring larger diameter wire or additional supports
Solution Approach 1:
The wires are pre-tensioned during the manufacturing process using automated tensioning equipment. This preliminary tensioning imparts the necessary rigidity to thin-wire screens without requiring larger diameter wires or additional support structures, while maintaining the manufacturing simplicity of modular assembly
Solution Approach 2:
The manufacturing process incorporates controlled tensioning parameters that optimize wire tension to provide adequate rigidity. By adjusting tension levels during assembly, the system achieves the required structural stiffness with thinner wires, eliminating the need for additional support elements
4Strength
If additional supports are added to provide rigidity for untensioned wires, then wire rigidity is improved, but the throughput of the modular screen is reduced
Solution Approach 1:
The wires are pre-tensioned during manufacturing to achieve the required rigidity before installation. This eliminates the need for additional support structures that would block screening openings, thereby maintaining maximum throughput while providing adequate structural stiffness for thin-wire screens
