Innovation Solution

Dissolving acetylsalicylic acid or diosmin or drotaverine in an organic solvent, mixing with dispersing agents in water, and using ultrasonic homogenization to create nanoparticles with diameters between 50-500 nm, stabilized by lecithin, gelatin, and starch, preventing aggregation and enhancing bioavailability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional nanoparticle manufacturing methods are used, then nanoparticle formation is achieved, but bioavailability and stability are not effectively enhanced

Engineering Contradiction:
Improvebioavailability and stabilityVSAvoidmanufacturing effectiveness
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent changes the physical-chemical parameters of the system by using ultrasonic homogenization to transform macroscopic particles into nanoparticles (50-500 nm size range). This parameter change in particle size directly enhances bioavailability and stability while maintaining manufacturing feasibility through a relatively simple process

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies ultrasonic vibration (mechanical vibration) to homogenize the mixture of organic and aqueous phases, breaking down particles into nanoscale dimensions. This mechanical energy input achieves stable nanoparticle formation with improved bioavailability without complex manufacturing steps

Inventive Principle:
Principle #18Mechanical vibration

2Reliability

If nanoparticle aggregation occurs, then particle size increases, but stability and bioavailability are reduced

Engineering Contradiction:
ImprovestabilityVSAvoidparticle size consistency
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent introduces an intermediary substance (surfactant or stabilizer) that mediates between the hydrophobic nanoparticle core and the aqueous environment. This intermediary prevents aggregation by providing steric or electrostatic repulsion, maintaining stable particle size distribution and enhancing overall stability

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent forms a protective shell or film around the nanoparticle core using polymers or surfactants. This flexible coating prevents particle aggregation while maintaining the integrity and size of the nanoparticles, ensuring stable composition and improved bioavailability

Inventive Principle:
Principle #30Flexible shells and thin films

3Quantity of substance

If organic solvent concentration is increased to dissolve active substance, then solubility improves, but toxicity and stability may worsen

Engineering Contradiction:
Improvesolubility of active substanceVSAvoidtoxicity and stability
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent replaces chemical dissolution mechanisms with physical homogenization through ultrasonic treatment. Instead of relying on high concentrations of organic solvents to dissolve the active substance, the process uses mechanical energy to disperse particles at the nanoscale, reducing the need for toxic solvents while maintaining solubility and stability

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

Solution Approach 2:

The patent utilizes phase transition principles by creating a biphasic system (organic and aqueous phases) that transitions into a stable nanoparticle dispersion. The active substance partitions between phases during homogenization, achieving high solubility in the final nanoparticle form without requiring excessive organic solvent, thus reducing toxicity while maintaining stability

Inventive Principle:
Principle #36Phase transitions
