Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive sheets made from mesh fibers face challenges in maintaining adhesion and print quality due to ink absorption issues and adhesive degradation, leading to poor appearance and potential harm from harmful substances in decorative films.
Innovation Solution
A sticker-type adhesive mesh is developed with a porous mesh fabric, a stack of thin adhesive layers, an absorption layer, and a release paper, where the adhesive is applied in thin films using micro gravure printing to prevent ink penetration and maintain adhesion, and the absorption layer absorbs excess ink, ensuring excellent print quality and adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive is applied to the back of mesh fabric, then adhesion is achieved, but ink absorption rate decreases and ink permeates through the mesh fabric causing adhesive degradation and easy peeling
Solution Approach 1:
The adhesive system is segmented into multiple thin layers (first adhesive layer 30, second adhesive layer 50) separated by an absorption layer 40. This segmentation prevents ink from reaching and degrading the adhesive layers while maintaining adhesion functionality.
Solution Approach 2:
The absorption layer 40 acts as an intermediary barrier between the ink layer 10 and the adhesive layers (30, 50). It absorbs excess ink and prevents it from permeating through the mesh fabric 20 to react with and degrade the adhesive components.
2Strength
If adhesive is applied to the back of mesh fabric, then adhesion is achieved, but adhesive fills in pores between fibers causing poor appearance
Solution Approach 1:
The adhesive layers (30, 50) are applied locally to specific regions rather than uniformly across the entire mesh fabric surface. This localized application ensures adhesive strength is provided where needed while leaving the porous structure visible in other areas to maintain appearance quality.
Solution Approach 2:
The adhesive is applied as thin film layers (30, 50) that conform to the mesh fabric surface without filling the pores. The thin film structure provides adhesion while allowing the underlying porous mesh structure to remain visible, maintaining the natural fiber appearance.
3Ease of manufacture
If solvent ink is output, then printing is achieved, but ink is absorbed excessively between fibers decreasing print quality
Solution Approach 1:
The absorption layer 40 serves as an intermediary that controls ink distribution. It absorbs excess solvent ink that would otherwise be absorbed excessively by the mesh fibers, thereby preventing degradation of print quality while still allowing printing to proceed.
Solution Approach 2:
The ink absorption characteristics are modified by introducing the absorption layer 40 with specific porous properties. This layer changes the absorption parameters from uncontrolled fiber absorption to controlled layer absorption, improving print quality.
