Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing agricultural agents are used for pest control, then pest control effect is achieved, but specificity and environmental safety are compromised

Engineering Contradiction:
Improvepest control effectVSAvoidenvironmental impact
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by designing a benzamide derivative with specific substituent patterns at defined positions (R1-R6) to achieve targeted pest control activity while reducing non-specific environmental effects. The structured substitution pattern ensures the compound acts specifically on target pests rather than broadly affecting all organisms.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent employs parameter changes by systematically varying the chemical structure parameters (different substituent groups at various positions on the benzamide core) to optimize the balance between pest control efficacy and environmental safety. By adjusting molecular parameters, the compound achieves high effectiveness against pests while minimizing harmful environmental impacts.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If existing agricultural agents are used for pest control, then general pest suppression is achieved, but specificity for target pests is reduced

Engineering Contradiction:
Improvepest control efficiencyVSAvoidspecificity to target pests
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent implements local quality through specific substituent arrangements at defined positions on the benzamide molecule, creating a structure that specifically targets pest neurological systems while sparing non-target organisms. This localized structural optimization provides both high productivity against pests and high adaptability/specificity to target species.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If broad-spectrum agricultural agents are used, then wide pest coverage is achieved, but safety and selectivity are compromised

Engineering Contradiction:
Improvepest coverage rangeVSAvoidsafety profile
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses parameter changes by modifying the benzamide core structure with specific substituent groups to achieve broad pest coverage through varied molecular parameters while maintaining safety. The systematic variation of R1-R6 substituents allows the compound to target multiple pest types without compromising safety, as each substitution pattern can be tuned for specific pest groups while maintaining overall selectivity.

Inventive Principle:
Principle #35Parameter changes
