Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If chemical fungicides are used to combat plant pathogens, then pathogen control effectiveness is improved, but pesticide-resistant strains develop and health problems occur

Engineering Contradiction:

Improvepathogen control effectivenessVSAvoidpesticide resistance and health issues

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces chemical fungicides (mechanical/chemical system) with biological agents including Trichoderma viride fungus, its filtrate, and fermentation byproducts. This substitution eliminates pesticide resistance development and health hazards while maintaining pathogen control effectiveness through biological mechanisms such as mycoparasitism and production of antifungal compounds.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses Trichoderma viride filtrate and fermentation byproducts as intermediary substances that mediate between the biological agent and plant pathogens. These intermediaries contain antifungal compounds, organic acids, and growth regulators that indirectly control pathogens while promoting plant growth, avoiding direct contact with harmful chemicals.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If biological fungicides are used to avoid chemical fungicide issues, then health safety is improved, but vitality and activity are lost over time

Engineering Contradiction:

Improvehealth safetyVSAvoidvitality retention time

Core Design Contradiction:

Object-affected harmful factorsVSDuration of action of stationary object

Solution Approach 1:

The patent applies parameter changes by optimizing storage conditions (temperature, humidity, packaging atmosphere) and formulation composition to extend the viability duration of Trichoderma viride. The filtrate and fermentation byproducts are stabilized through controlled parameters that prevent degradation, maintaining biological activity for extended periods during storage and transport.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates composite formulations combining Trichoderma viride with its own filtrate and fermentation byproducts. This composite structure provides mutual protection and enhancement, where the byproducts act as stabilizers and growth promoters that extend the vitality of the fungus while maintaining health safety benefits.

Inventive Principle:

Principle #40Composite materials

3Duration of action of stationary object

If biocontrol formulation stability is improved through storage, then shelf-life is extended, but application frequency may need adjustment

Engineering Contradiction:

Improveshelf-lifeVSAvoidapplication frequency

Core Design Contradiction:

Duration of action of stationary objectVSProductivity

Solution Approach 1:

The patent applies preliminary action by pre-stabilizing the biocontrol formulation during manufacturing and storage, preparing it for extended shelf-life before application. The Trichoderma viride and its byproducts are formulated in advance with protective matrices that maintain viability during storage, reducing the need for frequent reapplications after field deployment.

Inventive Principle:

Principle #10Preliminary action
