Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing solid state forms of Vericiguat are used, then the basic pharmaceutical function is achieved, but processing properties and stability are inadequate

Engineering Contradiction:
ImprovestabilityVSAvoidprocessing properties
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies parameter changes by discovering and utilizing different polymorphic forms of Vericiguat, each with distinct crystal structures and physical properties. By changing the solid state form parameter from one polymorph to another, the invention achieves improved processing properties and stability simultaneously. Specifically, certain polymorphic forms exhibit better flowability, compressibility, and thermal stability, directly resolving the contradiction between ease of manufacture and reliability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs phase transitions by converting Vericiguat between different solid state forms (polymorphs) through controlled crystallization processes. By inducing specific phase transitions during manufacturing, the invention optimizes both processing characteristics and final product stability. The ability to transition between polymorphic forms allows selection of the most suitable form for specific manufacturing operations while ensuring long-term stability.

Inventive Principle:
Principle #36Phase transitions

2Productivity

If existing solid state forms of Vericiguat are used, then the pharmaceutical activity is maintained, but dissolution profile and bioavailability are not optimized

Engineering Contradiction:
ImprovebioavailabilityVSAvoiddissolution profile
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent utilizes parameter changes by selecting specific polymorphic forms of Vericiguat that exhibit superior dissolution characteristics. Different polymorphs have varying solubility and dissolution rates, and the invention identifies and applies the forms that optimize bioavailability while maintaining pharmaceutical activity. This direct manipulation of the solid state form parameter enables simultaneous improvement of both productivity (bioavailability) and reliability (dissolution profile).

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If additional solid state forms of Vericiguat are developed, then processing and stability are improved, but the complexity of the formulation options increases

Engineering Contradiction:
Improveprocessing propertiesVSAvoidformulation options
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent applies segmentation by categorizing Vericiguat into distinct polymorphic forms with well-defined characteristics. Rather than presenting a complex continuum of options, the invention segments the solid state space into discrete, manageable polymorphs, each with specific processing and stability properties. This segmentation simplifies formulation development by providing clear options rather than overwhelming complexity.

Inventive Principle:
Principle #1Segmentation
