Solution Overview

Problem

Existing methods for producing bioactive component-containing composites face challenges such as low absorption due to micron-sized clay minerals, high toxicity from synthetic polymers, and incomplete solvent evaporation, leading to inefficient and toxic drug formulations.

Innovation Solution

A method involving homogenization, spray drying, and homogenization of clay minerals with bioactive components and non-toxic macromolecules in a solvent-free process to produce nano-composites with high bioactive component loading and low toxicity.

Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
ImproveefficacyVSAvoidsize
Core Design Contradiction:
ReliabilityVSLength of moving object

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improvelayer separationVSAvoidtoxicity
Core Design Contradiction:
ShapeVSObject-affected harmful factors

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.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

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

Engineering Contradiction:
Improvebioactive component loadingVSAvoidtoxicity
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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

Engineering Contradiction:
Improveparticle sizeVSAvoidyield
Core Design Contradiction:
Length of moving objectVSProductivity

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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

Engineering Contradiction:
Improveparticle sizeVSAvoidyield
Core Design Contradiction:
Length of moving objectVSProductivity

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.

Inventive Principle:
Principle #35Parameter changes
