Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repeated usage of a single fungicide is applied to control fungal diseases, then disease management effectiveness is improved initially, but pathogen resistance develops over time reducing efficacy
Solution Approach 1:
The patent introduces a novel compound with a specific chemical structure (Formula I) featuring a glutarimide ring and polyketide backbone, representing a parameter change in chemical structure to achieve new antimicrobial activity. This structural innovation provides a different mode of action against pathogens, potentially overcoming resistance developed to conventional fungicides
Solution Approach 2:
The invention combines multiple structural elements (polyketide chain, glutarimide ring, specific substituents) into a composite molecular structure that exhibits broad-spectrum antimicrobial activity. This composite approach may provide multiple targets or mechanisms of action, reducing the likelihood of resistance development
2Reliability
If conventional antibiotics are used to control bacterial diseases, then bacterial growth is inhibited initially, but antibiotic resistance spreads reducing treatment effectiveness
Solution Approach 1:
The patent presents a novel compound structure (Formula I) with a glutarimide ring that has not been previously described in the art. This structural parameter change may result in new mechanisms of bacterial cell inhibition that bypass existing resistance mechanisms
Solution Approach 2:
The compound is extracted from Streptomyces sp. strain, isolating the active antimicrobial principle from the natural source. This extraction provides a pure, defined compound that can be characterized and tested for activity against resistant bacterial strains
3Adaptability or versatility
If new antibiotics are continuously developed to overcome resistance, then treatment options are expanded, but the ability of bacteria to adapt and acquire resistance to new antibiotics reduces long-term effectiveness
Solution Approach 1:
The compound is derived from Streptomyces sp., a natural source that has evolved over millions of years to produce antimicrobial substances. This bio-inspired approach leverages nature's self-optimized solutions rather than relying solely on human-designed antibiotics, potentially providing more sustainable long-term effectiveness
