Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing crop protection compositions are used, then they provide basic pest control function, but they have limited spectrum of action and develop resistance
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of crop protection agents through specific bicyclic heterocyclic core structures with varied substituents (R1-R6, R6a, R7-R11). This structural parameter modification creates novel compounds with improved spectral activity against multiple pest types while maintaining efficacy and reducing resistance development through different modes of action.
2Object-affected harmful factors
If existing pesticides are applied, then they control pests, but they show toxicity and harm beneficial species
Solution Approach 1:
The patent applies local quality by designing pesticides with specific localized functional groups and substituent patterns on the bicyclic heterocyclic core. This enables selective toxicity where the molecule interacts specifically with target pest receptors while sparing beneficial species, achieving high efficacy against pests with reduced non-selective harm.
3Adaptability or versatility
If complex synthesis routes are used, then diverse compounds can be produced, but manufacturing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the synthesis into modular stages: constructing the bicyclic heterocyclic core structure first, then systematically adding different substituent groups (R1-R6, R6a, R7-R11) in subsequent steps. This segmented approach enables diverse compound production through combinatorial chemistry while maintaining manageable synthesis complexity through standardized intermediate structures.
