Polymer Film Graphics Manufacturing via Layer Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing polymer film graphics result in significant waste due to the need for cutting the graphics from the polymer film, which is costly and inefficient.
Innovation Solution
A process involving a continuous substrate with a release layer and an adhesive layer, where an image layer is applied and cured in the shape of the graphic, eliminating the need for cutting by allowing the graphic to be wound into a roll or applied directly to a surface without cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the graphic is cut from the polymer film using existing methods, then the graphic can be applied to substrates, but significant film waste is generated and manufacturing costs increase
Solution Approach 1:
The invention segments the polymer film into functional layers: a release layer that can be selectively removed, an image layer containing the graphic design, and an adhesive layer. This segmentation allows the image layer to be separated from the release layer through selective dissolution, eliminating the need to cut the entire film and thus reducing waste.
Solution Approach 2:
The invention utilizes parameter changes in the form of selective solubility. The release layer is designed to be soluble in a specific solvent, allowing it to be removed selectively from the image layer. This chemical parameter change enables the graphic to be released without mechanical cutting, reducing material waste.
2Ease of operation
If the graphic is cut from the polymer film, then the graphic can be transferred to substrates, but manufacturing costs increase due to waste
Solution Approach 1:
The polymer film is segmented into distinct functional layers (release layer, image layer, adhesive layer) that can be selectively removed and transferred. This segmentation enables the graphic to be transferred to substrates without requiring costly cutting operations, thereby reducing manufacturing costs while maintaining ease of operation.
Solution Approach 2:
The release layer is extracted or removed selectively from the image layer through solvent dissolution. This extraction process allows the image layer to be isolated and transferred to substrates without the need for mechanical cutting, reducing manufacturing costs while preserving the graphic transfer capability.
3Loss of substance
If the release layer is removed by dissolution, then the image layer can be released without cutting, but the process requires specific solvents and conditions
Solution Approach 1:
The invention employs parameter changes by selecting specific solvent parameters that are soluble to the release layer but not to the image layer. This chemical selectivity enables waste reduction through dissolution rather than cutting, and the process complexity is managed by choosing appropriate solvent systems.
Solution Approach 2:
A solvent acts as an intermediary substance that facilitates the removal of the release layer. The solvent temporarily combines with the release layer to dissolve it, enabling separation from the image layer without mechanical cutting. This intermediary approach reduces waste while the solvent system itself manages the process complexity.
