Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If functional components are attached to a polymer scaffold to create multimeric systems, then therapeutic effectiveness and binding affinity are improved, but the chemical formulation becomes undefined and the number of functional components cannot be controlled
Solution Approach 1:
The invention divides the multimeric system into distinct modular components: a polymer scaffold and separately attached functional components. This segmentation allows independent control and characterization of each component while maintaining the overall therapeutic function, resolving the contradiction between therapeutic effectiveness and manufacturing precision.
Solution Approach 2:
The patent employs preliminary characterization and definition of the polymer scaffold's chemical formulation before attaching functional components. By establishing the scaffold's structure and properties in advance, the invention enables precise control over the final multimeric system's composition and stoichiometry, addressing the manufacturing precision issue.
2Power
If multiple functional components are combined in one multimeric molecule, then synergistic therapeutic effect is achieved, but the binding specificity and affinity become unpredictable
Solution Approach 1:
The invention implements feedback mechanisms through characterization techniques that measure and monitor the binding properties of multimeric systems. By analyzing the interaction between functional components and targets, the patent enables optimization of binding specificity and affinity while maintaining synergistic effects.
Solution Approach 2:
The patent systematically varies and optimizes parameters such as the number, type, and arrangement of functional components attached to the polymer scaffold. This parameter optimization allows tuning of binding affinity and specificity while preserving synergistic therapeutic effects.
3Power
If the number of functional components is increased on a polymer molecule, then therapeutic potency is enhanced, but the reproducibility and control of the system deteriorate
Solution Approach 1:
The invention develops a universal polymer scaffold platform that can accommodate varying numbers and types of functional components through standardized attachment mechanisms. This universality enables reproducible production of multimeric systems with different functional compositions while maintaining consistent manufacturing processes.
