Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing compounds are used for controlling harmful arthropods, then control function is provided, but efficacy and specificity are limited
Solution Approach 1:
The patent modifies the chemical structure of existing arthropod control compounds by changing molecular parameters - specifically introducing a pyrimidine ring structure with specific substituents (R1-R6 groups) at defined positions. This structural parameter change enhances both efficacy and specificity against harmful arthropods while reducing impact on beneficial organisms.
Solution Approach 2:
The invention creates a composite chemical structure combining a pyrimidine core with various substituent groups (R1-R6 representing different chemical groups at specific positions). This composite molecular structure integrates multiple functional characteristics to achieve enhanced bioactivity and specificity against target arthropods.
2Reliability
If existing compounds are used for controlling harmful arthropods, then control function is provided, but specificity against target pests is insufficient
Solution Approach 1:
The patent applies local quality modification by placing specific substituent groups (R1-R6) at particular positions on the pyrimidine ring structure. This localized structural modification creates specific interaction sites that enhance affinity for harmful arthropod neuro receptors while avoiding binding to beneficial organisms, thereby improving specificity and reducing harmful effects on non-target species.
