Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing formulations of LA1 are used, then the basic anti-inflammatory activity is maintained, but the dissolution profile, pharmacokinetic profile, and stability profile are insufficient

Engineering Contradiction:
ImproveefficacyVSAvoidstability profile
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent changes the physical and chemical parameters of LA1 by creating multiple crystalline forms (Forms A-N) with different crystal structures, and by forming salt compounds with various bases. These parameter changes result in improved stability profiles, dissolution rates, and pharmacokinetic properties while maintaining the anti-inflammatory efficacy of the compound.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates composite formulations by combining LA1 with different salt-forming bases (such as choline, meglumine, and other pharmaceutically acceptable bases) to produce salt compounds. These composite materials exhibit improved stability and pharmacokinetic profiles compared to the free acid form of LA1.

Inventive Principle:
Principle #40Composite materials
