Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional heavy metal removal methods (physical, chemical, dialysis, ion exchange, reverse osmosis, solvent extraction) are used, then heavy metal removal capability is achieved, but cost increases and environmental harm occurs
Solution Approach 1:
The patent converts the harmful effect of heavy metals into a beneficial selection criterion by isolating probiotic strains that not only tolerate but thrive in heavy metal-contaminated environments. The strain Lacticaseibacillus paracasei FMBL L23249 FJX was specifically selected for its ability to ferment Cicer arietinum L. leach liquor in the presence of heavy metals, transforming the contamination problem into a functional advantage for producing resilient probiotic products
Solution Approach 2:
The patent introduces probiotic microorganisms as intermediary agents that mediate between heavy metal contamination and human consumption. These probiotics act as biological filters and protectors, utilizing their cell walls, extracellular polymeric substances, and metabolic processes to bind and neutralize heavy metals while producing beneficial postbiotics that counteract metal toxicity
2Productivity
If different probiotic strains are used for fermenting Cicer arietinum L. leach liquor, then fermentation capability varies, but strain specificity limits universal application
Solution Approach 1:
The patent achieves universality by selecting a probiotic strain that simultaneously performs multiple functions: fermenting Cicer arietinum L. leach liquor efficiently, tolerating heavy metal contamination, producing postbiotics with therapeutic value, and maintaining stability during storage. The strain Lacticaseibacillus paracasei FMBL L23249 FJX serves as a multi-functional agent that addresses fermentation, detoxification, and product stabilization in one integrated system
