Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If current standard storage media (optical discs, hard drives, magnetic tapes) are used, then data storage is achievable, but the lifetime is limited to only a few years and maintenance costs are high
Solution Approach 1:
The patent replaces mechanical/electronic storage systems (hard drives, optical discs, magnetic tapes) with a biochemical storage system using DNA synthesis and sequencing. This substitution enables data to be stored in a molecular format that is inherently stable and resistant to degradation, achieving lifetimes of thousands of years while eliminating the mechanical failure modes that limit conventional storage media.
2Quantity of substance
If DNA is used as storage medium, then enormous information capacity and long term stability are achieved, but the synthesis cost and complexity are high
Solution Approach 1:
The patent segments the DNA storage process into distinct functional modules: data encoding algorithms that convert digital data to nucleotide sequences, modular synthesis protocols using standard oligonucleotide chemistry, and systematic sequencing workflows. This segmentation allows each component to be optimized independently and enables parallel processing, reducing overall complexity while maintaining high information capacity.
Solution Approach 2:
The patent employs universal DNA storage protocols that can encode and store any type of digital data (text, images, video, databases) using the same biochemical framework. The encoding schemes are agnostic to data format, and the synthesis/sequencing infrastructure serves multiple purposes including data storage, verification, and retrieval, thereby reducing system complexity through multi-functionality.
3Reliability
If enzymatic synthesis is used for DNA assembly, then the process is more reliable, but the productivity is lower compared to chemical synthesis
Solution Approach 1:
The patent prepares DNA sequences in advance by encoding digital data into nucleotide sequences using computational algorithms, and pre-synthesizes oligonucleotide building blocks through chemical methods before the enzymatic assembly step. This preliminary preparation of digital-to-biological translation and modular DNA fragments enables the enzymatic synthesis phase to focus solely on reliable assembly, thereby maintaining high reliability while improving overall productivity through parallel preprocessing steps.

AI summary
A method of storing information in nucleic acid includes processing units of information into permutation numbers by a reversible algorithm, providing a library of n distinct oligonucleotide strings of predetermined length in a fixed order, n being a positive integer and each distinct oligonucleotide string associated with a distinct index indicating the ordinal position, assembling distinct oligonucleotide strings to create strands comprising at least two oligonucleotide strings, each oligonucleotide string's ordinal position matching with a permutation number, each strand including at least a data bearing part and a semantic part, and the semantic part to allocate orientation and/or order to a strand.
