Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional data storage media are used, then writing technology is simple and成熟, but storage density is low and storage time is short
Solution Approach 1:
The patent replaces traditional mechanical/electronic storage systems with a chemical/biological system using DNA molecules for data storage. Digital information is encoded into DNA sequences through synthesis, enabling ultra-high storage density and long-term preservation without relying on conventional storage media mechanics
Solution Approach 2:
The patent fundamentally changes the physical-chemical parameters of the storage medium by using DNA molecules instead of magnetic or electronic media. This enables storage density to increase from gigabytes to exabytes per gram, and storage time to extend from years to millennia under appropriate conditions
2Quantity of substance
If molecular data storage is implemented, then storage density increases significantly, but writing quality and writing speed become unsatisfactory
Solution Approach 1:
The patent segments the DNA writing process into distinct functional units: encoding modules that convert digital data into DNA sequences, synthesis modules that chemically synthesize the DNA, and control modules that coordinate the process. This segmentation enables precise control over writing quality while maintaining high storage density
Solution Approach 2:
The patent implements feedback mechanisms through quality detection modules that analyze synthesized DNA sequences to verify accuracy, and error correction algorithms that detect and correct synthesis errors. This closed-loop control system ensures high writing quality by continuously monitoring and adjusting the synthesis process
3Quantity of substance
If molecular data storage is implemented, then storage density increases significantly, but writing cost increases
Solution Approach 1:
The patent performs preliminary encoding of digital data into DNA-compatible sequences before synthesis, and pre-optimizes synthesis pathways to minimize reagent consumption and processing steps. This preliminary preparation reduces the overall cost by preventing errors that would require expensive re-synthesis
Solution Approach 2:
The patent recovers and reuses expensive reagents and enzymes from the DNA synthesis process through purification and regeneration steps. Unused DNA sequences and chemical byproducts are also recovered and reused, significantly reducing the cost per bit of storage
