Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synthetic nitrites are used to inhibit microbial growth and enhance color, then preservative benefits are improved, but health risks increase due to nitrosamine formation
Solution Approach 1:
The patent converts the harmful effect of nitrites by using plant-based nitrates (from spinach, celery, beetroot) that naturally convert to nitrites through bacterial action during fermentation or cooking. This natural conversion process provides the desired preservation effects while reducing nitrosamine formation, effectively turning a potentially harmful synthetic additive into a safer natural alternative.
Solution Approach 2:
The patent changes the chemical parameter from synthetic nitrites to plant-based nitrates. By using natural nitrate sources that convert to nitrites in situ through bacterial action, the patent maintains the preservative function while altering the chemical pathway to reduce harmful nitrosamine formation during high-temperature cooking.
2Object-affected harmful factors
If plant-based additives are used to replace synthetic nitrites, then health risks are reduced, but preservative effectiveness may be insufficient
Solution Approach 1:
The patent creates a composite approach by combining multiple plant-based nitrate sources (spinach powder, celery powder, beetroot powder) to achieve the desired preservative effectiveness. This composite of natural nitrate sources provides sufficient nitrite conversion through bacterial action to match synthetic nitrite functionality while maintaining health benefits.
3Object-affected harmful factors
If natural nitrate sources are used, then nitrosamine formation is inhibited, but the complexity of achieving desired preservation effects increases
Solution Approach 1:
The patent applies preliminary action by pre-converting nitrates to nitrites through bacterial fermentation or cooking processes before the meat product is prepared. This preliminary conversion simplifies the final cooking process and reduces the complexity of controlling nitrite levels, as the nitrites are already present from the natural conversion process.
