Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current treatments for autoimmune diseases are used, then disease management is attempted, but they are often ineffective and have significant disadvantages
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of ceramide molecules, specifically varying the fatty acid chain length (C16-C26) and degree of unsaturation (0-3 double bonds) to optimize immunomodulatory activity. This structural parameter optimization enables more effective NK T cell activation compared to conventional treatments, directly addressing the reliability issue while maintaining safety profiles.
Solution Approach 2:
The invention utilizes composite molecular structures combining sphingosine bases with varied fatty acid chains and hydroxyl groups at specific positions. These composite ceramide derivatives work synergistically to modulate immune responses, providing both effectiveness in treating autoimmune diseases and cancer, while reducing the harmful side effects associated with current therapeutic approaches.
2Reliability
If NK T cells are activated to modulate immune responses, then treatment effectiveness for autoimmune diseases and cancer is improved, but the complexity of immune modulation increases
Solution Approach 1:
The patent employs local quality by introducing hydroxyl groups at specific positions (position 2, 3, or 4) on the sphingosine backbone and at specific positions on the fatty acid chain. This localized functional group placement creates distinct ceramide derivatives with specialized immunomodulatory properties, enabling precise control over NK T cell activation while simplifying the overall therapeutic approach compared to broad immune modulation strategies.
