Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing data storage media such as hard drives, optical media, and magnetic tapes are used, then data can be stored on physical media, but the data becomes corrupted after prolonged storage
Solution Approach 1:
The patent replaces mechanical/magnetic storage systems with a chemical/biochemical system using DNA or polymer molecules. Data is encoded in the sequence of monomers within polymer molecules, transforming the storage mechanism from physical/magnetic fields to molecular-scale chemical structures that are inherently more stable and resistant to degradation over time.
Solution Approach 2:
The invention changes the fundamental parameter of storage medium from traditional magnetic or optical materials to synthetic polymers or DNA molecules. This parameter change enables data to be stored in the molecular sequence rather than magnetic domains or optical patterns, significantly improving long-term stability and durability against corruption.
2Quantity of substance
If data storage capacity is increased, then more data can be stored, but the storage devices get ever smaller
Solution Approach 1:
The patent employs nanopores with dimensions on the order of nanometers to contain and manipulate polymer molecules. These nanoporous structures provide a highly compact framework that can hold vast amounts of data in extremely small volumes, achieving ultra-high storage density by utilizing the three-dimensional space within nanopores efficiently.
Solution Approach 2:
The invention transitions from two-dimensional surface storage to three-dimensional molecular storage within nanopores. By encoding data in the sequential arrangement of monomers along the polymer chain that threads through the nanopore, the system exploits the third dimension (molecular length scale) to achieve extraordinary storage capacity in minimal physical space.
3Reliability
If nanopore-based data storage is implemented, then stable and efficient data storage with high capacity is achieved, but the system complexity increases
Solution Approach 1:
The nanopore device is designed to perform multiple functions: it serves as both the storage medium container and the reading mechanism. The same nanopore structure that holds the polymer molecule also enables detection of the encoded data through measurements of electrical properties or resonance frequency, eliminating the need for separate writing and reading apparatus and simplifying the overall system.
Solution Approach 2:
The polymer or DNA molecule itself serves as both the data storage medium and the data carrier. The molecular structure naturally maintains the encoded information through its stable chemical bonds, and the same molecule can be directly detected as it passes through the nanopore, requiring minimal external intervention for both storage and retrieval operations.

AI summary
A novel system and method of storing and reading digital data, including providing a nanopore polymer memory device having at least one memory cell comprising at least two addition chambers each arranged to add a unique chemical construct (or codes) to a polymer (or DNA) string when the polymer enters the respective addition chamber, the data comprising a series of the codes; successively steering the polymer through the nanopore into the addition chambers to add the codes to the polymer to create the digital data pattern on the polymer; and accurately controlling the bit rate of the polymer using a servo controller. The device may have loading chamber(s) to load (or remove) the polymer into/from the deblock chambers through at least one micro-hole. The cell may be part of a memory system that stores and retrieves "raw" data and allows for remote retrieval and conversion.
