Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If DNA synthesis is used to write data, then data storage capacity is improved, but cost and synthesis time increase excessively
Solution Approach 1:
The patent uses DNA replication instead of synthesis to write data. Natural DNA polymerases replicate the DNA backbone containing stored information, enabling data writing without expensive and time-consuming de novo synthesis. This copying approach maintains high storage capacity while dramatically reducing cost and time.
Solution Approach 2:
The system employs natural DNA replication mechanisms where DNA polymerases automatically replicate the stored information. The biological system serves itself by using inherent enzymatic processes rather than requiring external synthetic intervention, thereby reducing operational costs and time requirements.
2Reliability
If natural DNA is used for storage, then information integrity is maintained, but compatibility with silicon computing architectures is poor
Solution Approach 1:
The patent creates a composite system combining natural DNA backbones with synthetic non-natural nucleic acid analogs. The natural DNA portion maintains information integrity and biological compatibility, while the synthetic components enable integration with silicon-based computing and storage systems, bridging the gap between biological and electronic domains.
Solution Approach 2:
The non-natural nucleic acid analogs serve as intermediaries between natural DNA and silicon computing architectures. These hybrid molecules facilitate data transfer and processing between biological DNA storage and electronic systems, enabling compatibility without compromising the integrity of stored information.
3Ease of manufacture
If DNA synthesis cost is reduced, then ease of manufacture is improved, but information integrity may be compromised
Solution Approach 1:
Instead of synthesizing DNA from scratch, the system copies existing DNA sequences using natural replication mechanisms. This approach dramatically reduces manufacturing cost while maintaining the high fidelity of natural DNA replication processes, preserving information integrity without expensive synthesis.
Solution Approach 2:
The patent extracts only the essential DNA backbone structure for data storage, separating it from the expensive synthesis process. By using pre-existing DNA backbones and natural replication rather than de novo synthesis, the system reduces manufacturing cost while maintaining the reliability of DNA-based information storage.
