Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a high molecular weight polymer is produced by conventional methods, then the molecular weight increases, but the internal pressure increases and operation becomes unstable
Solution Approach 1:
The patent introduces a compressive fluid as an intermediary substance that mediates between the monomer and the polymerization process. The compressive fluid allows polymerization to proceed while maintaining stable internal pressure and preventing the operational instability that normally occurs when producing high molecular weight polymers
Solution Approach 2:
The patent changes the physical and chemical parameters of the polymerization system by introducing a compressive fluid, which alters the reaction conditions to enable stable production of high molecular weight polymers. This includes modifying pressure, density, and solubility parameters to maintain operational stability
2Quantity of substance
If a high molecular weight polymer is produced by conventional methods, then the molecular weight increases, but the viscosity increases leading to unstable operation
Solution Approach 1:
The compressive fluid serves as a mediator that reduces the viscosity impact of high molecular weight polymer production. It allows the polymer to achieve high molecular weight while the fluid maintains manageable viscosity levels for stable operation
Solution Approach 2:
The compressive fluid changes the viscosity parameter of the system by providing a different physical environment for polymerization, enabling high molecular weight production without the proportional increase in viscosity that causes operational difficulties
3Productivity
If monomer is polymerized in melted state, then polymerization can proceed, but yield decreases due to heat influence
Solution Approach 1:
The patent changes the physical state parameter of the monomer from melted state to compressed fluid state. This parameter change allows polymerization to proceed at lower temperatures, maintaining high productivity while preventing thermal decomposition and improving product yield
Solution Approach 2:
The patent utilizes a phase transition approach by using the compressive fluid to enable polymerization without requiring the monomer to be in a melted state. The compressive fluid creates conditions where polymerization can occur in a different phase, avoiding heat-related yield losses
