Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If new therapeutic compositions are developed to inhibit pathological angiogenesis, then treatment effectiveness for diseases like cancer and macular degeneration is improved, but the complexity of drug formulation and crystalline structure characterization increases

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidformulation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by discovering and characterizing different crystalline forms (polymorphs) of Compound 1, each with distinct X-ray powder diffraction patterns. Crystalline form E shows a largest peak at 10-11 degrees 2θ, while crystalline form F shows a largest peak at 17-18 degrees 2θ. These parameter changes in molecular arrangement lead to improved therapeutic reliability for inhibiting pathological angiogenesis in diseases like cancer and macular degeneration.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent utilizes phase transitions by preparing different crystalline forms through specific crystallization processes. Crystalline form E is prepared by mixing Compound 1 with methanol, while crystalline form F is prepared by crystallizing Compound 1 in water and isopropanol. These phase transition processes from solution to solid crystalline state enable the formation of distinct polymorphic forms with different therapeutic properties.

Inventive Principle:
Principle #36Phase transitions

2Adaptability or versatility

If multiple crystalline forms are prepared through different crystallization methods, then therapeutic options and efficacy are improved, but the manufacturing process complexity increases

Engineering Contradiction:
Improvetherapeutic optionsVSAvoidmanufacturing process complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent applies segmentation by dividing the manufacturing process into distinct pathways for producing different crystalline forms. One pathway involves mixing Compound 1 with methanol to produce crystalline form E, while another pathway involves crystallizing Compound 1 in water and isopropanol to produce crystalline form F. This segmentation allows selective production of specific crystalline forms based on therapeutic needs, improving adaptability while maintaining manageable manufacturing complexity through standardized procedures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent uses intermediary substances (solvents) to mediate the formation of different crystalline forms. Methanol serves as an intermediary in producing crystalline form E, while water and isopropanol serve as intermediaries in producing crystalline form F. These intermediary solvents facilitate the phase transition from solution to crystalline solid, enabling controlled formation of specific polymorphic forms with distinct therapeutic properties.

Inventive Principle:
Principle #24Intermediary (Mediator)
