Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional storage media (hard drives, optical media, magnetic tapes) are used, then data storage is achieved, but data stability and integrity deteriorate over prolonged storage periods
Solution Approach 1:
The patent changes the fundamental material parameter from traditional magnetic/optical media to DNA polymer, which has inherently different chemical stability properties. DNA's molecular structure provides resistance to degradation over time, enabling data to remain stable for centuries rather than decades, directly resolving the contradiction between reliability and storage duration
Solution Approach 2:
The invention uses composite structures combining DNA polymers with nanopore devices and electronic readout systems. This hybrid approach integrates the long-term stability of DNA with the readability of electronic systems, maintaining data integrity over extended periods while enabling reliable retrieval
2Quantity of substance
If data storage capacity is increased, then more data can be stored, but storage device size must be reduced, creating complexity in the storage system
Solution Approach 1:
The patent transitions from two-dimensional surface storage to three-dimensional volumetric storage by synthesizing DNA strands that can be stacked and stored in solution. This dimensional change allows exponential increases in storage capacity without proportionally increasing device footprint, as DNA can be packed densely in liquid phase and retrieved on-demand
Solution Approach 2:
The invention extracts only the essential data storage function from traditional complex storage devices, using minimal physical infrastructure (nanopores, electrodes, fluidic channels) to achieve high-density storage. By removing unnecessary mechanical components and using molecular-scale storage media, the system achieves high capacity with reduced overall complexity
3Reliability
If nanopore-based memory systems are used, then data storage stability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs self-assembling DNA structures and naturally formed nanopores that automatically position themselves with high precision during synthesis. The DNA polymerization process inherently creates uniformly spaced nucleotides that serve as natural data storage positions, eliminating the need for externally imposed precision manufacturing constraints
Solution Approach 2:
The invention uses porous alumina membranes with naturally occurring uniform pore structures as templates for nanopore device fabrication. These commercially available membranes provide consistent pore sizes and spacing without requiring complex nanofabrication processes, thereby maintaining data integrity while reducing manufacturing precision requirements

AI summary
The disclosure provides a novel system and method of storing multi-bit information, including providing a nano-channel-based polymer memory device, the device having at least one memory cell comprising at least two addition nano-channels, each of the addition nano-channels arranged to add a unique chemical construct (or codes) to the polymer when the polymer enters the respective addition nano-channel, the polymer having a bead or origami on a non-writing end of the polymer; each nano-channel having a nano-port constriction having a port width which allows the polymer to pass through the nano-port, and does not allow the bead or origami to pass through and does not allow addition or deblocking enzymes (or beads attached thereto) to pass through the nano-port; successively steering the polymer through the nanopore into the addition nano-channels to add the codes to the polymer based on a predetermined digital data pattern to create the digital data pattern on the polymer.
