Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional extraction methods are used to prepare plant extracts, then the extraction process is simple, but the effectiveness in enhancing AKK bacteria abundance is insufficient
Solution Approach 1:
The extraction process is divided into multiple sequential steps: maceration extraction first, followed by adsorption, then elution, and finally concentration. Each step isolates and processes specific components, with the maceration step extracting active ingredients from Forsythia suspensa leaves using solvent, the adsorption step separating components using adsorption resin, the elution step recovering target compounds, and the concentration step producing the final extract. This segmentation enables effective enhancement of AKK bacteria abundance while maintaining systematic control over the complex process
Solution Approach 2:
Adsorption resin is introduced as an intermediary substance to facilitate the separation and purification of active ingredients during the extraction process. The resin acts as a mediator between the maceration extract and the final product, selectively adsorbing target compounds and enabling their subsequent elution and concentration. This intermediary step is crucial for obtaining an extract with sufficient purity and effectiveness for enhancing AKK bacteria abundance
2Quantity of substance
If high dosage of Forsythia suspensa leaf extract is administered, then the abundance of AKK bacteria increases significantly, but the cost and potential side effects increase
Solution Approach 1:
The dosage of Forsythia suspensa leaf extract is optimized to identify the minimum effective dose that achieves significant enhancement of AKK bacteria abundance. Animal experiments determined that a dosage of 75 mg/kg or more per day produces substantial increases in AKK bacteria abundance. This parameter optimization balances the quantity of bacteria enhancement with the reduction of potential side effects and cost, establishing 75 mg/kg as the threshold dosage for effective and safe application
