Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If ginkgo terpene lactone is formulated as an ordinary oral preparation, then the drug can be administered conveniently, but the bioavailability is limited and clinical efficacy is reduced

Engineering Contradiction:
ImprovebioavailabilityVSAvoidformulation complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent employs porous silica gel as a carrier material to load ginkgo terpene lactone. The porous structure provides high surface area and porosity, enabling enhanced drug loading capacity and controlled release, thereby improving bioavailability while maintaining formulation feasibility

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The patent creates a composite formulation combining ginkgo terpene lactone with porous silica gel and other excipients. This composite structure leverages the adsorption properties of silica gel and the pharmacological activity of the active ingredient, achieving improved bioavailability through material synergism

Inventive Principle:
Principle #40Composite materials

2Quantity of substance

If ginkgo terpene lactone is formulated with increased drug loading, then the therapeutic effect is enhanced, but the dissolution rate becomes limited

Engineering Contradiction:
Improvedrug loadingVSAvoiddissolution rate
Core Design Contradiction:
Quantity of substanceVSSpeed

Solution Approach 1:

The porous silica gel carrier provides a high surface area matrix that accommodates increased drug loading while maintaining rapid dissolution through its porous structure. The pores facilitate quick drug release into the dissolution medium, resolving the trade-off between loading capacity and dissolution rate

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The patent modifies the physical parameters of the formulation by using porous materials with specific pore sizes and surface areas. This changes the dissolution kinetics by increasing the surface area to volume ratio, enabling both high drug loading and rapid dissolution simultaneously

Inventive Principle:
Principle #35Parameter changes
