Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bioactive materials are used in industrial processes and storage, then their functional activity is lost due to oxidation and chemical decomposition, but using protective formulations increases product complexity
Solution Approach 1:
The patent uses polysaccharide particles as an intermediary carrier to protect bioactive materials. The particles adsorb the bioactive substances, creating a protective interface that shields them from harmful environmental factors like oxidation and chemical decomposition during storage and industrial processing
Solution Approach 2:
The patent changes the physical and chemical parameters of the bioactive material by controlling the concentration of solutes (keeping it below 5%) and optimizing the mass ratio of bioactive solution to polysaccharide particles (0.25:1 to 1:1). These parameter adjustments enhance stability while maintaining formulation simplicity
2Reliability
If bioactive materials are exposed to harsh industrial processes like milling and extrusion, then their activity is destroyed, but avoiding these processes reduces productivity
Solution Approach 1:
The patent applies preliminary protection by adsorbing bioactive materials onto polysaccharide particles before industrial processing. This pre-protection allows the materials to withstand harsh conditions like milling, mixing, and extrusion without losing functional activity, thereby maintaining productivity
3Reliability
If solute concentration in the bioactive solution is increased to enhance stability, then the stability improves, but the cost and complexity of purification increases
Solution Approach 1:
The patent optimizes the solute concentration parameter by keeping it below 5% in the bioactive solution. This parameter setting provides sufficient stability during storage and processing while avoiding the need for complex and costly purification processes that would be required at higher solute concentrations
