Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing membrane assemblies lack stability in the feeding of frame materials, particularly in roll form, which affects the reliability and efficiency of the membrane assembly production process.
Innovation Solution
A device and method involving a delamination station to remove a protective film from the frame material, followed by lamination with a carrier web to stabilize the frame material before transfer to a transport device, ensuring distortion-free transport and assembly of the membrane assembly as roll goods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frame material is fed as a roll product without protective film delamination and carrier web lamination, then the process is simpler and faster, but the stability and reliability of frame material transport deteriorates
Solution Approach 1:
The protective film is delaminated from the frame material in advance before the frame material is fed to the transport device. This preliminary delamination action prevents instability during subsequent transport and assembly operations, resolving the contradiction between simple feeding and reliable transport by performing the necessary preparation beforehand.
Solution Approach 2:
A carrier web is introduced as an intermediary element between the frame material and the transport device. The carrier web is laminated to the frame material after delamination of the protective film, providing stable transport support while allowing the frame material to be handled reliably. This intermediary carrier web resolves the contradiction by enabling stable feeding without requiring direct complex handling of the frame material itself.
2Reliability
If protective film is delaminated and carrier web is laminated to frame material, then transport stability is improved, but processing time increases
Solution Approach 1:
The delamination of the protective film and the lamination of the carrier web are performed in a continuous sequence without interruption. The frame material moves continuously through the delamination station and then to the lamination station, maintaining continuous useful action. This continuous processing minimizes idle time and resolves the contradiction between stability improvement and time loss by ensuring no unnecessary停顿 occurs during the preparatory operations.
3Productivity
If frame material is transported without carrier web lamination, then the process is more efficient, but distortion during transport increases
Solution Approach 1:
The carrier web serves as an intermediary support structure that prevents distortion of the frame material during transport. By laminating the carrier web to the frame material after protective film removal, the frame material gains stable support that maintains its shape and position. This allows efficient continuous production while preventing distortion, resolving the contradiction between productivity and shape integrity.
Solution Approach 2:
The carrier web is designed as a flexible thin film structure that conforms to the frame material while providing sufficient support to prevent distortion. This flexible carrier web allows the frame material to be transported in roll form without rigid constraints, maintaining productivity while ensuring distortion-free transport through the flexible support it provides.
