Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If RNA molecules are delivered using conventional methods, then delivery efficiency is low, but the complexity of the delivery system remains simple
Solution Approach 1:
The patent employs composite nanoparticle structures composed of multiple functional components including RNA molecules, protective coatings, and targeting ligands. These composite nanoparticles integrate multiple functions (protection, delivery, targeting) into a single delivery system, thereby improving delivery efficiency while managing complexity through functional integration rather than separate delivery mechanisms
Solution Approach 2:
The delivery system is segmented into distinct functional modules: the RNA cargo, the nanoparticle carrier, protective elements, and targeting components. This modular segmentation allows each component to be optimized independently for its specific function while maintaining overall system efficiency, resolving the contradiction between improved delivery and system complexity
2Manufacturing precision
If conventional delivery methods are used, then cell specificity is poor, but the cost of the delivery system remains low
Solution Approach 1:
The nanoparticle surface is modified with specific targeting ligands at localized positions to recognize and bind to receptors uniquely expressed on target cells. This local quality enhancement (adding specificity at the interaction interface) improves cell targeting precision without requiring complete redesign of the entire delivery system, thus managing complexity while achieving high specificity
3Stability of the object's composition
If RNA molecules are delivered without compaction, then stability during transport is low, but the manufacturing process remains simple
Solution Approach 1:
The RNA molecules are nested within the nanoparticle structure, which provides physical protection and a stable environment during transport. This nesting approach encapsulates the fragile RNA cargo within a protective carrier, enhancing stability during circulation and delivery while maintaining relatively simple manufacturing processes through self-assembly or straightforward encapsulation techniques
