Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional neonicotinoid compounds and tolclofos-methyl are used as active ingredients, then pest control activity is provided, but the controlling effect is not optimal

Engineering Contradiction:

Improvecontrolling effectVSAvoidformulation development

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent identifies specific structural parameters of the neonicotinoid compound (formula 1 with specific groups A, Z, R1, R2, X, Y) and optimal weight ratios (0.002:1 to 500:1) to achieve superior controlling effect. This resolves the contradiction by optimizing the chemical parameters rather than using conventional compounds without specific structural requirements.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite active ingredient system combining tolclofos-methyl with specifically structured neonicotinoid compounds (formula 1). This composite approach synergistically improves the controlling effect against pests while maintaining ease of formulation through defined composition ratios.

Inventive Principle:

Principle #40Composite materials

2Reliability

If higher concentrations of active ingredients are used to improve controlling effect, then pest control efficacy increases, but phytotoxicity risk increases

Engineering Contradiction:

Improvecontrolling effectVSAvoidphytotoxicity

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent optimizes the concentration parameters by establishing a specific weight ratio range (0.002:1 to 500:1) between tolclofos-methyl and the neonicotinoid compound. This parameter optimization achieves high controlling effect while maintaining safety against phytotoxicity, as the balanced ratio prevents excessive concentration of any single ingredient that could harm plants.
