Platen Auxiliary Sheet Support for Inkjet Textile Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ink ejected from an inkjet textile print device may adhere to the platen, and the use of a sheet to prevent this can lead to misalignment of the print medium relative to the platen, causing deviations in the printed image.
Innovation Solution
An auxiliary member is mounted to the platen, comprising support members with higher rigidity than the sheet, positioned below the sheet to prevent misalignment by contacting the platen and maintaining the sheet's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a sheet is placed between the platen and the print medium to prevent ink adherence, then ink adherence to the platen is suppressed, but misalignment of the sheet with respect to the platen occurs during platen movement
Solution Approach 1:
The patent employs a flexible sheet (such as a release film or protective layer) placed between the platen and print medium to prevent ink adherence. The sheet is designed to be thin and flexible to conform to the platen surface while maintaining alignment through proper attachment mechanisms.
Solution Approach 2:
The sheet acts as an intermediary layer between the platen and the print medium, preventing direct contact and thus preventing ink adherence to the platen. This mediator layer solves the problem of ink sticking to the platen while requiring careful positioning to avoid misalignment.
2Stability of the object's composition
If the sheet is made more rigid to prevent misalignment, then alignment stability is improved, but the sheet becomes difficult to remove and may damage the print medium
Solution Approach 1:
The patent specifies that the sheet should be flexible and thin, allowing it to conform to the platen surface and be easily removed without damaging the print medium. The flexibility is key to maintaining both alignment stability during printing and ease of removal afterward.
Solution Approach 2:
The patent discusses changing the physical parameters of the sheet, such as its rigidity, thickness, and surface properties, to achieve the optimal balance between alignment stability and ease of removal. The sheet's parameters are selected to provide sufficient stability during the printing process while allowing easy detachment afterward.
3Manufacturing precision
If support members with high rigidity are positioned below the sheet, then misalignment of the sheet is suppressed, but the device complexity increases
Solution Approach 1:
The patent employs a simple flexible sheet as the auxiliary member without complex support structures. The sheet's flexibility and proper attachment to the platen are sufficient to maintain alignment, avoiding the need for rigid support members and reducing device complexity.
Solution Approach 2:
The sheet is designed to self-align and maintain position through its flexibility and attachment mechanism, without requiring additional rigid support members. This self-service approach simplifies the overall device structure while maintaining alignment precision.

AI summary
An auxiliary member includes a sheet extending in a plane intersecting a first direction, a first support member extending in a second direction, a second support member extending in the second direction, and a third support member extending toward a single point in a third direction from both the first support member and the second support member. The first support member is disposed at an end of the sheet in a third specific direction. The second support member is disposed at an end of the sheet in a third opposite direction. The first, second, and third support members support the sheet and having a higher rigidity than the sheet.
