Flexible Print Medium Carrier for Deformation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible print media, such as textiles, deform when subjected to mechanical forces during printing, leading to inaccuracies in print results.
Innovation Solution
A carrier with a higher tensile strength than the print medium is used to support and advance the print medium through the print zone, minimizing deformation by applying controlled tension and using an adhesive surface to maintain contact, thereby reducing mechanical stress on the print medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If mechanical forces are applied to convey the flexible print medium through the print zone, then the print medium can be transported, but the flexible print medium deforms under tensile, torsion or shear force
Solution Approach 1:
A carrier web is introduced as an intermediary element between the printing device and the flexible print medium. The carrier web has higher tensile strength and stiffness properties, allowing it to withstand mechanical conveying forces without deforming. The flexible print medium is mounted on this rigid carrier, enabling accurate transport through the print zone while the carrier absorbs the mechanical stresses.
Solution Approach 2:
The system is divided into two functional components: the carrier web and the flexible print medium. The carrier web handles the mechanical transport function with high strength properties, while the flexible print medium focuses on the printing function. This segmentation allows each component to be optimized for its specific purpose without compromising the other.
2Device complexity
If the flexible print medium is directly conveyed through the print zone, then the process is simple, but deformation occurs leading to inaccurate print results
Solution Approach 1:
The carrier web serves as a mediator that adds minimal complexity to the system while solving the deformation problem. It is a simple web-like structure that can be easily integrated into the existing printing process, providing the necessary mechanical support without requiring complex additional mechanisms.
3Manufacturing precision
If a carrier with higher tensile strength is used to support the print medium, then deformation is reduced, but the device complexity increases
Solution Approach 1:
The carrier web is designed as a simple intermediary element that can be easily integrated into the printing system. It provides the necessary mechanical support through its material properties rather than through complex structural designs, keeping the overall system complexity low while achieving high print accuracy.
Solution Approach 2:
The solution changes the physical parameters of the supporting structure by using a carrier web with higher tensile strength and stiffness. This parameter change allows the carrier to resist deformation under mechanical loads, improving print accuracy without requiring complex mechanical systems.
