Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clay minerals are used in micron size for composite structures, then the composite structure can be formed with bioactive components, but the absorption in the body is low and efficacy is very low
Solution Approach 1:
The patent applies segmentation by reducing clay mineral particles from micron size to nano-size (1-100 nm thickness), dividing the original large particles into much smaller units. This size reduction enables penetration through intestinal membranes and significantly improves absorption and efficacy in the body.
2Shape
If a high amount of polymer or macromolecules is used to separate layers of micron-sized clay minerals, then layer separation is achieved, but toxicity increases due to synthetic polymers
Solution Approach 1:
The patent replaces expensive and toxic synthetic polymers with natural, biocompatible macromolecules such as proteins, polysaccharides, and peptides. These natural macromolecules achieve the same layer separation function without the harmful effects of synthetic polymers, providing a safe and effective alternative.
3Quantity of substance
If organic solvents are used to load bioactive components into MMT layers, then bioactive components can be loaded, but solvent content cannot be completely evaporated and toxicity increases
Solution Approach 1:
The patent extracts and eliminates organic solvents from the composite structure by using alternative water-based or solvent-free loading methods. Bioactive components are loaded into MMT layers using aqueous solutions or direct incorporation, completely removing the toxic organic solvent residue that would otherwise remain after evaporation.
4Length of moving object
If mechanical grinding methods are used to reduce MMT to nano-size, then nano-size particles are obtained, but yield is very low
Solution Approach 1:
The patent replaces mechanical grinding methods with chemical or biochemical approaches such as acid treatment, enzymatic degradation, or ultrasonic fragmentation. These alternative methods achieve nano-size reduction with significantly higher yields and better particle uniformity compared to traditional mechanical grinding.
5Length of moving object
If centrifuge method is used to reduce MMT to nano-size, then nano-size particles are obtained, but yield varies significantly based on clay source
Solution Approach 1:
The patent employs parameter changes by adjusting chemical treatment conditions (acid concentration, temperature, time) or processing parameters (ultrasonic power, duration) to optimize nano-size reduction. This approach achieves consistent high yields across different clay sources by tailoring the processing parameters to each specific clay type.
