Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical fungicides are used to combat fungal pathogens, then pathogen control effectiveness is improved, but pesticide-resistant strains develop and health problems occur
Solution Approach 1:
The patent converts the harmful effects of chemical fungicide overuse into a beneficial alternative by developing a biocontrol formulation using Trichoderma viride filtrate. The filtrate contains conidia and fermentation byproducts that naturally combat fungal pathogens without causing resistance or health issues, thus converting the problem of chemical dependency into a sustainable biological solution
Solution Approach 2:
The patent changes the fundamental parameter of pathogen control from chemical to biological agents. By using Trichoderma viride filtrate with conidia and fermentation byproducts (organic acids, growth regulators, amino acids), the system transitions from synthetic chemistry to biochemistry, maintaining effectiveness while eliminating harmful side effects
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
Solution Approach 1:
The patent creates a composite biocontrol formulation by combining Trichoderma viride filtrate (containing conidia and fermentation byproducts) with inert substances. This composite structure protects the biological agents from degradation while maintaining their vitality and activity, solving the problem of biological fungicide instability over time
Solution Approach 2:
The inert substances in the formulation act as intermediaries that protect the Trichoderma viride conidia and fermentation byproducts from environmental stress and degradation. These inert carriers maintain the biological activity of the active ingredients during storage and application, preventing loss of vitality
3Reliability
If endophytic Trichoderma is used for biocontrol, then pathogen combatting and plant growth promotion are achieved, but formulation stability during storage is compromised
Solution Approach 1:
The patent formulates endophytic Trichoderma conidia and fermentation byproducts with inert substances to create a stable composite formulation. This composite structure maintains the biological activity and pathogen-fighting capabilities of Trichoderma while ensuring formulation stability during storage and handling
Solution Approach 2:
The patent applies different properties to different components of the formulation: the Trichoderma viride filtrate provides biological activity and pathogen combatting capabilities, while the inert substances provide structural stability and storage stability. This local differentiation of functions resolves the contradiction between biological efficacy and formulation stability
