Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If organic solvent extraction is used to obtain Ganoderma lucidum extract, then solubility is improved, but the preparation process becomes complex and costly with difficulty in removing impurities
Solution Approach 1:
The patent extracts only the necessary active components from Ganoderma lucidum using water extraction, removing the need for complex organic solvent extraction processes. This takes out the harmful organic solvents while retaining the essential polysaccharides and other active ingredients, simplifying the preparation process while maintaining extract stability
Solution Approach 2:
The patent changes the extraction parameter from organic solvents to water, and optimizes extraction temperature and time parameters. This parameter change eliminates the need for multiple solvent systems while achieving effective extraction of active components, reducing process complexity and impurity formation
2Ease of manufacture
If simple screen filtering is used for water extraction, then the preparation process is simplified, but the extract becomes unstable with precipitation and poor clarity
Solution Approach 1:
The patent segments the filtration process into multiple stages: coarse filtration to remove large particles, followed by fine filtration to remove smaller impurities. This segmentation allows each filtration stage to target specific particle sizes, achieving both process simplicity and extract stability without requiring complex single-step filtration
Solution Approach 2:
The patent performs preliminary actions including soaking the Ganoderma lucidum material before extraction, and conducting extraction at optimized temperature and time conditions. These preliminary actions prepare the material for easier filtration and prevent precipitation during storage, maintaining extract stability while keeping the process simple
3Stability of the object's composition
If multiple extraction steps with different solvents are used, then solubility is improved, but the cost increases and large scale production becomes difficult
Solution Approach 1:
The patent makes water serve multiple functions: as extraction solvent, as purification medium, and as the final product base. This multi-functionality eliminates the need for multiple different solvents (petroleum ether, ethanol, chloroform, ethyl acetate), reducing cost and simplifying the process for large-scale production while maintaining extract solubility through optimized water extraction parameters
