Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bacteria are incorporated into pharmaceutical agents, then therapeutic efficacy is improved, but stability over time deteriorates
Solution Approach 1:
The bacteria are freeze-dried in advance before incorporation into the pharmaceutical agent, creating a stable dried form that maintains viability during storage and administration. This preliminary processing step prepares the bacteria for long-term stability while preserving their therapeutic activity.
Solution Approach 2:
The physical state of the bacteria is changed from live wet form to freeze-dried powder form, fundamentally altering their stability parameters. This parameter change enables them to maintain viability and stability over extended periods under various storage conditions while retaining therapeutic efficacy.
2Quantity of substance
If bacteria are maintained at high total cell counts, then therapeutic efficacy is improved, but maintaining viability over time becomes more difficult
Solution Approach 1:
The high cell count bacteria are freeze-dried in advance, creating a stable dried form that maintains viability during storage and administration. This preliminary processing step prepares the bacteria for long-term stability while preserving their high cell count and therapeutic activity.
Solution Approach 2:
The physical state of the bacteria is changed from live wet form to freeze-dried powder form, fundamentally altering their stability parameters. This parameter change enables them to maintain viability and stability over extended periods under various storage conditions while retaining high cell count.
3Adaptability or versatility
If pharmaceutical agents are stored under various storage conditions, then accessibility is improved, but stability deteriorates
Solution Approach 1:
The bacteria are transformed into a freeze-dried state, fundamentally changing their physical and chemical parameters to become resistant to degradation under various storage conditions. This parameter change enables the pharmaceutical agent to maintain stability across different temperatures and environmental conditions.
Solution Approach 2:
The pharmaceutical agent combines freeze-dried bacteria with appropriate excipients and protective agents to create a composite formulation that maintains bacterial stability under various storage conditions. This composite structure provides both adaptability to different storage environments and maintained stability.
