Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing insecticides are used continuously, then initial pesticidal effect is achieved, but pest resistance develops over time

Engineering Contradiction:
Improvepesticidal effectVSAvoidpest resistance
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces novel chemical compounds with modified molecular structures (formula 1) that differ from existing insecticides. By changing the chemical parameters and structural characteristics of the active ingredient, the new compounds can effectively target pests that have developed resistance to conventional insecticides, thereby restoring and maintaining reliable pesticidal effects.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If novel chemical compounds are developed, then superior pesticidal activity is achieved, but development complexity increases

Engineering Contradiction:
Improvepesticidal activityVSAvoidcompound structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a systematic approach to compound development by defining specific structural components and substituents in formula (1). The molecule is segmented into core tetrahydropyridine structure with variable aromatic substituents (Q1-Q56), allowing researchers to systematically modify and optimize individual components while maintaining the overall framework that provides superior pesticidal activity.
