Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If existing ectoparasite control methods are used, then some level of parasite control is achieved, but the duration of action is insufficient and systemic application is inadequate
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of carboxamide derivatives to achieve prolonged systemic activity. Specifically, the compound formula (2) with specific substituents (R1, R2, X, X5, A, Y) is designed to optimize pharmacokinetic properties, enabling the active ingredient to maintain effective concentrations in the animal's system for extended periods, thereby resolving the contradiction between duration of action and systemic application reliability
Solution Approach 2:
The patent employs composite materials through formulation development that combines the carboxamide derivative active ingredient with inert carriers and optional auxiliary agents. This composite formulation approach enhances the systemic delivery and prolonged release of the active compound, allowing sustained ectoparasite control while maintaining safety for warm-blooded animals
2Productivity
If higher doses are administered to achieve faster parasite reduction, then efficacy increases, but toxicity to warm-blooded animals may increase
Solution Approach 1:
The patent applies local quality by designing the carboxamide derivative with specific molecular characteristics that enable selective action against ectoparasites while sparing warm-blooded animals. The compound structure (Formula 2) is optimized to target pest-specific physiological pathways, allowing high efficacy against parasites at doses that remain safe for the host animal
Solution Approach 2:
The patent utilizes parameter changes by optimizing the chemical parameters of the carboxamide derivative to achieve selective toxicity. The specific substituents and structural features of Formula (2) are designed to alter the compound's interaction with biological targets, enabling differential effects between ectoparasites and warm-blooded animals, thus achieving high productivity without increased harmful factors
