Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fully formed cage structures are used, then structural stability is improved, but flexibility and ease of cargo attachment deteriorate
Solution Approach 1:
The patent divides the traditional fully formed cage structure into separate components: a protein shell and cargo attachment sites. This segmentation allows the shell to maintain structural stability while the attachment sites provide flexibility for cargo loading, resolving the contradiction between stability and adaptability.
Solution Approach 2:
The patent introduces dynamic elements that allow the nanoparticle structure to transition between different states. The cargo attachment mechanism can dynamically bind and release cargo, providing flexibility while the core shell maintains structural stability, thus resolving the contradiction between rigidity and adaptability.
2Strength
If fully formed cage structures are used, then structural integrity is improved, but cargo attachment complexity increases
Solution Approach 1:
By segmenting the cage structure into a stable shell and separate cargo attachment components, the patent simplifies the manufacturing process. The shell can be produced independently with high structural integrity, while cargo attachment is simplified through modular design, resolving the contradiction between strength and ease of manufacture.
Solution Approach 2:
The patent introduces intermediary elements that facilitate cargo attachment without compromising shell integrity. These intermediaries act as mediators between the stable shell structure and the cargo, simplifying the attachment process while maintaining structural strength.
3Ease of manufacture
If minimalist non-cage elements are used, then fabrication simplicity and cargo attachment ease are improved, but stability and rigidity worsen
Solution Approach 1:
The patent merges minimalist non-cage elements with a protein shell structure. This combination retains the fabrication simplicity of minimalist approaches while the protein shell provides the necessary stability and rigidity, resolving the contradiction between ease of manufacture and structural stability.
Solution Approach 2:
The patent employs composite material strategies by combining protein shell components with synthetic or biological cargo attachment elements. This composite approach achieves both fabrication simplicity and structural stability by leveraging the advantages of different material types.
