Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen support rods for pulling continuous screens into paper machines risk damaging the screen surface during installation due to rough surfaces, and existing solutions to prevent this are complex and space-constrained.
Innovation Solution
A screen support rod system using a carbon fiber composite (CFC) support tube with a shrink tube made of thermoplastic material that forms a smooth surface, combined with a telescoping rod and sliding bushings for axial movement, ensuring the screen is not damaged during installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the screen support rod uses a carbon fiber composite support tube with rough surface, then the support rod is lightweight and strong, but the screen surface is damaged during installation
Solution Approach 1:
A shrink tube is introduced as an intermediary component between the carbon fiber support tube and the screen. The shrink tube provides a smooth surface that prevents screen damage while allowing the underlying CFC tube to maintain its lightweight and strong properties. The shrink tube acts as a protective mediator during the screen installation process.
Solution Approach 2:
The solution combines carbon fiber composite material for the support tube structure with a thermoplastic shrink tube coating. This composite approach allows the system to achieve both the mechanical advantages of CFC (lightweight, strength) and the protective advantages of the shrink tube (smooth surface, screen protection).
2Object-affected harmful factors
If the entire frame is moved into the paper machine to avoid screen damage, then the screen surface is protected, but the device complexity increases and space constraints are violated
Solution Approach 1:
The harmful rough surface is extracted and isolated to a separate shrink tube component, while the main CFC support tube structure remains intact and simple. This separation allows the protective function to be achieved without complicating the overall support structure or requiring space-consuming frame movements.
Solution Approach 2:
The shrink tube is a simple, inexpensive protective covering that can be easily applied and replaced if needed. It provides the necessary protection without requiring complex mechanical systems or significant space, making it a practical solution for screen protection during installation.
