Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive printing form attachment methods, such as double-stick tape and traditional adhesive layers, are cumbersome, time-consuming, and prone to residue issues, leading to surface irregularities and impaired print quality, especially when attaching and detaching printing sleeves during flexographic printing processes.
Innovation Solution
A seamless, tube-shaped adhesive printing form attachment layer with a permanently sticky exterior and an elastic support layer that can be easily pulled over a printing sleeve, providing improved durability, ease of use, and enhanced printing quality by eliminating seams and residue issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If double-stick tape is used to attach printing plate to printing sleeve, then the printing plate can be attached and detached, but the operation becomes cumbersome and time-consuming with residue issues
Solution Approach 1:
The patent extracts the adhesive function from separate tape pieces and integrates it into a continuous tube-shaped attachment layer that is pre-formed and ready for application. This eliminates the need for manual tape application and positioning operations.
Solution Approach 2:
The tube-shaped attachment layer is pre-formed with seamless construction before application to the printing sleeve. This preliminary preparation eliminates the need for time-consuming manual assembly of multiple tape pieces during the printing process.
2Area of stationary object
If multiple pieces of double-stick tape are used for attachment, then coverage is improved, but alignment becomes difficult and surface irregularities occur
Solution Approach 1:
The patent merges multiple separate tape pieces into a single continuous tube-shaped attachment layer. This unified structure eliminates alignment issues between multiple pieces while maintaining complete coverage of the printing sleeve surface.
Solution Approach 2:
The tube-shaped attachment layer provides a homogeneous, seamless surface without the irregularities that occur when multiple tape pieces are joined. The uniform structure ensures consistent adhesive properties across the entire attachment area.
3Strength
If double-stick tape is used for attachment, then the printing plate can be secured, but residues are left behind that interfere with reuse and printing performance
Solution Approach 1:
The patent changes the material parameters of the attachment layer by using photopolymeric adhesive that can be cleanly removed. The adhesive properties are engineered to provide strong attachment during use but allow residue-free removal, eliminating contamination of the printing plate and sleeve.
Solution Approach 2:
The tube-shaped attachment layer is designed to be removable without leaving residues on the printing plate or sleeve. This allows the printing plate and sleeve to be recovered in a clean state, ready for reuse without requiring extensive cleaning operations.
4Reliability
If sheets of adhesive material are applied to form the attachment layer, then the adhesive surface can be created, but seams are formed that create weak portions and surface irregularities
Solution Approach 1:
The patent segments the attachment layer into a tube shape that can be manufactured separately and then applied as a complete unit to the printing sleeve. This segmentation in manufacturing eliminates seams during application while maintaining reliable adhesive bonding.
Solution Approach 2:
The tube-shaped attachment layer provides a homogeneous, seamless surface without the irregularities that occur when multiple sheets are joined. The uniform structure ensures consistent adhesive properties across the entire attachment area.
