Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lipophilic bioactive agents are administered using conventional methods, then the treatment can be delivered, but the bioavailability is poor and side effects are numerous
Solution Approach 1:
The patent uses liposomes as intermediary carriers to deliver lipophilic bioactive agents. The liposomal structure encapsulates the bioactive agent, enabling controlled delivery and improving bioavailability while reducing direct exposure to healthy tissues, thereby minimizing side effects.
Solution Approach 2:
The patent modifies the physical and chemical parameters of the bioactive agent delivery system by incorporating permeation enhancers that alter the permeability characteristics of biological membranes, thereby improving the absorption and bioavailability of the lipophilic agent.
2Ease of operation
If permeation enhancers are added to the composition, then skin penetration is enhanced, but the formulation complexity increases
Solution Approach 1:
The patent creates a composite formulation combining liposomes containing lipophilic bioactive agents with permeation enhancers. This composite structure integrates multiple functional components into a unified delivery system that enhances skin penetration while managing formulation complexity through systematic design.
