Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If romidepsin is formulated without optimal excipients, then the formulation is simpler, but the solubility and stability of the drug are reduced
Solution Approach 1:
Mannitol is introduced as an intermediary substance (excipient) that mediates between the drug romidepsin and the formulation system. The mannitol provides solubility enhancement and stability improvement without directly altering the drug molecule, acting as a bridge that enables effective drug delivery while maintaining formulation simplicity
Solution Approach 2:
The formulation utilizes parameter changes by selecting mannitol with specific physical and chemical properties (solubility, stability profile, compatibility) to optimize the drug delivery system. By changing the excipient parameters rather than the drug parameters, the formulation achieves improved solubility and stability while keeping the drug structure intact
2Reliability
If existing romidepsin formulations are used, then the formulation is simpler, but the therapeutic delivery and bioavailability are not optimized
Solution Approach 1:
Mannitol serves as a mediator that enhances therapeutic delivery by improving drug solubility and stability in the formulation. This intermediary substance enables more reliable and consistent drug delivery to the patient without requiring complex delivery mechanisms or multiple components
Solution Approach 2:
By changing the excipient parameters (selecting mannitol with optimal solubility and stability characteristics), the formulation achieves improved therapeutic delivery and bioavailability. This parameter optimization approach enhances reliability without proportionally increasing formulation complexity
