Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electron beam curable water-based ink-jet ink compositions are used, then basic inkjet functionality is achieved, but storage stability is insufficient
Solution Approach 1:
The patent applies parameter changes by optimizing the content ratios of specific components: setting acrylamide derivative content at 20-55% by mass, resin emulsion solid content at 3-8% by mass, and water content at 40-75% by mass. These specific parameter ranges resolve the contradiction by achieving both storage stability and composition stability simultaneously, which conventional formulations fail to accomplish.
2Reliability
If conventional electron beam curable water-based ink-jet ink compositions are used, then basic inkjet functionality is achieved, but ejection stability is insufficient
Solution Approach 1:
The patent resolves ejection stability issues by implementing specific parameter changes in the ink composition. The acrylamide derivative content (20-55% by mass) and resin emulsion solid content (3-8% by mass) are optimized to ensure stable ejection performance, addressing the contradiction between achieving reliable ejection and maintaining composition stability.
3Strength
If conventional electron beam curable water-based ink-jet ink compositions are used, then basic coating film formation is achieved, but coating film resistance is insufficient
Solution Approach 1:
The patent applies composite materials principle by combining acrylamide derivatives with resin emulsions in specific ratios (acrylamide derivative 20-55% by mass, resin emulsion solid content 3-8% by mass). This composite formulation resolves the contradiction between achieving high coating film resistance and maintaining excellent coating film quality, which conventional single-component or less-optimized formulations cannot achieve.
4Reliability
If the acrylamide derivative content is increased to improve storage stability, then storage stability improves, but viscosity properties may deteriorate
Solution Approach 1:
The patent resolves this contradiction through precise parameter changes by limiting the acrylamide derivative content to 20-55% by mass and combining it with resin emulsion at 3-8% solid content. This balanced parameter optimization ensures both storage stability and appropriate viscosity properties, preventing the deterioration that would occur with excessive acrylamide derivative content alone.
