Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If water-based inks are used to replace oil-based inks, then toxicity and environmental protection issues are improved, but drying performance and color printing quality deteriorate
Solution Approach 1:
The patent modifies the chemical composition parameters of water-based ink by incorporating specific additives (resin, desiccant, defoamer, hardener, color fixative, dispersant) in optimized proportions. This changes the physical and chemical properties of the ink to achieve both environmental safety and printing quality, resolving the contradiction between toxicity reduction and manufacturing precision.
Solution Approach 2:
The patent creates a composite water-based ink formulation by combining multiple functional components (water, ink raw material, resin, desiccant, defoamer, hardener, color fixative, dispersant) into a unified system. This composite approach enables the ink to simultaneously achieve low toxicity, proper drying performance, and high color printing quality that cannot be obtained with simple water-based formulations.
2Object-affected harmful factors
If water-based inks are used, then environmental protection is improved, but adhesion strength deteriorates
Solution Approach 1:
The patent adjusts the chemical composition parameters by adding specific amounts of resin (6-12 vol%), hardener (4-9 vol%), and other functional additives to the water-based ink. These parameter modifications enhance the adhesion strength while maintaining the environmental benefits of water-based formulation, resolving the contradiction between toxicity reduction and adhesion strength.
Solution Approach 2:
The patent develops a composite water-based ink system that integrates multiple functional components working synergistically. The resin and hardener form a bonding matrix that provides strong adhesion to PVC film, while the water-based carrier maintains environmental safety. This composite structure resolves the contradiction between low toxicity and high adhesion strength.
3Object-affected harmful factors
If water-based inks are used, then environmental protection is improved, but tackiness increases causing staining during rolling
Solution Approach 1:
The patent modifies the physical parameters of the water-based ink by incorporating defoamer (3-8 vol%) and adjusting the solvent composition. These parameter changes reduce the surface tension and tackiness of the ink, preventing staining during the rolling and unrolling processes while maintaining the environmental advantages of water-based formulation.
Solution Approach 2:
The patent introduces defoamer and other surface-active agents as intermediary substances that modify the surface properties of the water-based ink. These intermediaries reduce tackiness and prevent direct adhesion to rolling surfaces, eliminating the staining problem while preserving the low-toxicity characteristic of water-based inks.
