Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adjuvants are added to pesticide formulations to improve foliar penetration and efficacy, then the insecticidal performance is improved, but the formulation stability deteriorates due to phase separation and poor compatibility

Engineering Contradiction:

Improveinsecticidal performanceVSAvoidformulation stability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent uses a specific emulsification system comprising non-ionic surfactants and co-surfactants as intermediaries between the adjuvants and the spirotetramat active ingredient. This emulsification system mediates the interaction between oil-soluble adjuvants and the pesticide formulation, preventing phase separation while maintaining enhanced foliar penetration and insecticidal efficacy.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a composite formulation system that integrates spirotetramat, adjuvants, and a specifically designed emulsification system into a stable unified composition. This composite material approach combines multiple components with complementary properties to achieve both formulation stability and improved pest control performance.

Inventive Principle:

Principle #40Composite materials

2Productivity

If adjuvants are added to enhance foliar penetration, then the uptake and distribution of active ingredient is improved, but the uniformity of spray distribution deteriorates due to poor compatibility

Engineering Contradiction:

Improvefoliar penetrationVSAvoidspray distribution uniformity

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The emulsification system acts as a intermediary that ensures uniform distribution of adjuvants throughout the formulation. The surfactants and co-surfactants create a stable emulsion that prevents premature separation, ensuring that the spray application remains uniform across the foliage while still enhancing penetration into the plant tissue.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If water-based spray solutions are used for pesticide application, then the formulation is simple and easy to apply, but the penetration through waxy surfaces of insects and plants is insufficient

Engineering Contradiction:

Improveapplication simplicityVSAvoidpenetration efficacy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent changes the physical-chemical parameters of the spray solution by incorporating adjuvants that modify surface tension and wetting properties. The emulsification system enables the formulation to maintain water-based applicability while achieving enhanced penetration through waxy surfaces by altering the interfacial properties of the spray droplets.

Inventive Principle:

Principle #35Parameter changes
