Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compounds similar to those described in prior art for medical use are employed, then medical application is achieved, but insecticidal activity is not obtained
Solution Approach 1:
The patent applies parameter changes by systematically modifying the chemical structure of the compound through varying substituents at different positions (R1-R6, X1-X6, Y1-Y6) and changing the core aromatic ring structure (formula 1 or formula 5). These structural parameter changes transform the compound from having only medical activity to exhibiting excellent insecticidal activity while maintaining medical utility.
2Quantity of substance
If small chemical amounts of the new amide derivative are used, then remarkable insecticidal efficacy is achieved, but conventional compounds require larger amounts for similar效果
Solution Approach 1:
The patent achieves high insecticidal efficacy at small chemical amounts through precise parameter changes in the molecular structure, including the introduction of specific electron-withdrawing and electron-donating groups at strategic positions, which optimize the compound's biological activity and potency.
3Reliability
If the new amide derivative is used alone, then excellent insecticidal control is achieved, but combination with other agrochemicals is also beneficial
Solution Approach 1:
The patent demonstrates universality by showing that the new amide derivative can function effectively both as a standalone insecticide and as part of combination formulations with other agrochemicals including insecticides, miticides, nematicides, fungicides, and plant growth regulators, providing versatile pest control solutions.
