Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The repeated use of printing blankets leads to dirt accumulation on hygroscopic materials, causing degradation in printing quality and increasing costs due to frequent replacements and maintenance.
Innovation Solution
An activation device with a storage tank, absorber, and peelable absorbing layers that constantly clean the printing blanket by transferring ink and solvent, allowing for efficient ink transfer and surface maintenance without damaging the hygroscopic material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the printing blanket is repeatedly pressed against a hygroscopic material for activation, then the ink transferability is maintained, but the surface of the hygroscopic material accumulates dirt and becomes damaged
Solution Approach 1:
The absorber is divided into multiple layers of absorbing members, with the uppermost layer being peelable. This segmentation allows the dirty surface layer to be separated and removed, while the underlying clean layers remain intact for continued use, thus resolving the dirt accumulation problem while maintaining ink transferability.
Solution Approach 2:
The peelable uppermost layer of the absorber, which accumulates dirt during repeated printing operations, is discarded by peeling it off. The remaining underlying layers are recovered and continue to function as the new active surface, eliminating the need to discard the entire absorber and reducing waste.
2Manufacturing precision
If the hygroscopic material is frequently replaced due to dirt and damage, then the printing quality is maintained, but the time and cost for replacement operations increase
Solution Approach 1:
By segmenting the absorber into a peelable uppermost layer and underlying layers, the system enables partial replacement rather than complete replacement. Only the contaminated upper layer needs to be removed, significantly reducing the time and frequency of replacement operations while maintaining printing quality.
Solution Approach 2:
The peelable uppermost layer is designed in advance to be separable from the underlying layers. This preliminary structural preparation allows for rapid removal and replacement of only the necessary portion, minimizing downtime and maintaining continuous printing operations without compromising quality.
3Reliability
If a solvent is applied to the printing blanket surface to prevent ink solidification, then the printing quality is maintained, but the hygroscopic material surface becomes damaged over time
Solution Approach 1:
The uppermost layer of the absorber is designed as a disposable component that can be easily peeled off and replaced. This layer absorbs the damage from solvent application and ink solidification, protecting the underlying structure. The disposable nature of this layer eliminates the cumulative damage problem while maintaining printing quality.
Solution Approach 2:
The peelable uppermost layer acts as an intermediary between the printing blanket and the underlying absorber structure. It absorbs the harmful effects of solvent application and ink interaction, protecting the structural integrity of the hygroscopic material while still enabling effective ink transfer and activation functions.

Implementation Method 1
an absorber (50) mounted on the storage tank (81), the absorber including layers of absorbing members and absorbing the liquid from an absorber lower part included in the absorber
Implementation Method 2
pressing the printing blanket, after the printing blanket is pressed against the cleaning surface, against an absorber including layers of absorbing members so that a part of a liquid permeating the absorber adheres to or permeates the printing blanket
