Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If petroleum-based solvents (Solvesso 100, Solvesso 150) are used, then good solvency for agrochemical active components is achieved, but toxicity to aquatic organisms and humans increases, and biodegradability deteriorates
Solution Approach 1:
The patent changes the chemical parameters of the solvent by using ester compounds with specific molecular structures (formula I) that have different physical and chemical properties compared to petroleum-based solvents. These ester solvents have lower toxicity and better biodegradability while maintaining adequate solvency for agrochemical active components.
Solution Approach 2:
The patent employs composite solvent systems by combining ester compounds with specific agrochemical active components in formulated compositions. This composite approach allows optimization of both solvency and safety parameters by selecting appropriate ester structures and concentrations.
2Quantity of substance
If aromatic hydrocarbons and cyclic hydrocarbons are used, then good solvency is achieved, but flammability increases due to low flash points
Solution Approach 1:
The patent changes the physical parameters of the solvent system by using ester compounds that inherently have higher flash points and lower volatility compared to aromatic and cyclic hydrocarbons. This parameter change maintains solvency capacity while significantly reducing flammability and fire hazards.
3Object-affected harmful factors
If polar solvents are used, then low toxicity is achieved, but solvent capacity for apolar pesticides deteriorates
Solution Approach 1:
The patent optimizes the polarity parameters of the solvent by selecting ester compounds with specific molecular structures that provide a balanced polarity profile. These esters are less polar than water-soluble solvents, enabling them to dissolve apolar pesticides effectively while maintaining low toxicity characteristics.
