Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing compounds are used to control plant diseases, then some disease control effect is achieved, but the control efficacy is insufficient against a wide range of plant diseases

Engineering Contradiction:
Improvecontrol efficacyVSAvoidrange of plant diseases controlled
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent modifies the chemical structure of existing compounds by changing parameters such as introducing specific substituents (e.g., chloro, fluoro, cyano groups) at defined positions on the phenylcyclohexanone molecule. These structural parameter changes enable the compound to achieve broad-spectrum efficacy against multiple plant pathogenic microorganisms including fungi, Oomycetes, and bacteria while maintaining high control reliability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite chemical structure combining a phenylcyclohexanone core scaffold with various functional groups and substituents. This composite molecular design allows the single compound class to interact with multiple types of plant pathogenic microorganisms through different mechanisms, achieving both broad range coverage and high control efficacy simultaneously.

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If a broad spectrum of plant diseases is targeted, then versatility is improved, but the compound complexity increases

Engineering Contradiction:
Improverange of plant diseases controlledVSAvoidcompound structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The phenylcyclohexanone compound is designed as a universal agent that can control multiple types of plant diseases through a single molecular structure. The core phenylcyclohexanone framework serves as a multi-functional platform that can target fungi, Oomycetes, and bacteria simultaneously, eliminating the need for multiple separate compounds and simplifying the overall system despite the broad spectrum coverage.

Inventive Principle:
Principle #6Universality (Multi-functionality)
