Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ethanol is produced from synthetic gas by microbial fermentation, then petrochemical resources can be replaced and resource recycling can be achieved, but the presence of unknown trace components and impurities reduces productivity and creates toxic effects on microorganisms
Solution Approach 1:
The patent applies preliminary action by conducting comprehensive purification of synthetic gas before microbial fermentation. The process removes impurities and toxic components (such as H2S, CO2, and other contaminants) from the raw synthetic gas produced from waste, creating a clean substrate that enables high-productivity fermentation while maintaining resource recycling benefits.
Solution Approach 2:
The patent uses an intermediary approach by introducing a controlled trace component composition into the ethanol production process. Rather than completely eliminating all trace components or using pure ethanol, the invention specifies a particular composition range of trace components that mediates between the need for resource recycling (using waste-derived synthetic gas) and the need for high productivity in downstream chemical processes.
2Quantity of substance
If conventional purification treatment such as distillation is used, then ethanol can be obtained, but various components derived from impurities cannot be completely removed
Solution Approach 1:
The patent applies preliminary action by performing extensive purification of the synthetic gas feedstock before fermentation occurs. This pre-purification step removes the source of impurities (contaminants in the waste-derived synthetic gas), thereby enabling the production of high-purity ethanol through conventional distillation without the problem of persistent impurity components.
3Adaptability or versatility
If ethanol contains trace components from waste-derived synthetic gas, then resource recycling is achieved, but the ethanol conversion rate in chemical processes decreases
Solution Approach 1:
The patent applies parameter changes by precisely controlling the composition parameters of trace components in the ethanol product. The invention specifies particular concentration ranges for various trace components, optimizing the balance between resource recycling (maintaining some trace components from waste-derived synthesis) and chemical process efficiency (maintaining high conversion rates in downstream applications).
