Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If DNA synthesis-based storage method is used, then storage density is improved, but writing speed deteriorates
Solution Approach 1:
The patent segments information into multiple fragments, each stored in a separate DNA molecule. This allows parallel processing of multiple storage operations simultaneously, improving writing speed while maintaining high storage density through the inherent compactness of DNA molecules.
Solution Approach 2:
The patent performs preliminary encoding and fragmentation of information before DNA synthesis. By pre-processing data into optimized fragments with appropriate error correction codes, the system reduces the complexity and time required for the actual DNA synthesis and assembly processes.
2Quantity of substance
If DNA synthesis-based storage method is used, then storage density is improved, but cost deteriorates
Solution Approach 1:
The patent uses PCR amplification to create multiple copies of synthesized DNA fragments. This allows a single synthesis operation to produce many identical storage units, significantly reducing the cost per unit of stored information while maintaining the high storage density advantage of DNA.
Solution Approach 2:
The patent employs universal adapters and primers that can be used across different DNA synthesis and amplification processes. This standardization reduces the need for custom reagents and protocols, lowering overall manufacturing costs while preserving the high storage capacity of DNA molecules.
3Quantity of substance
If molecular modules are increased to improve storage capacity, then storage density is improved, but reading and writing efficiency deteriorates
Solution Approach 1:
The patent divides information into multiple fragments stored in separate molecular modules (DNA molecules). During reading or writing operations, only the specific fragments needed are processed, rather than handling all molecular modules. This selective access maintains high storage density while improving operational efficiency.
Solution Approach 2:
The patent introduces index sequences and adapter regions as intermediaries between the information content and the DNA molecule structure. These intermediaries enable efficient identification, retrieval, and manipulation of specific information fragments without requiring processing of the entire molecular module, thus improving reading and writing efficiency while maintaining high storage density.
