Polysaccharide Structure Encoding for High-Density Archival Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current archival data storage methods using DNA face limitations such as reduced information density, slow read and write times, and environmental impact from rare earth metal mining, while magnetic tapes and disks have their own drawbacks.
Innovation Solution
Utilizing polysaccharides, particularly in chain or branched forms, to encode data through their structural configurations, enabling higher storage capacity and stability, with synthesis and reading processes optimized for efficient archival storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If DNA is used for archival storage, then storage stability is improved, but information density is reduced
Solution Approach 1:
The patent changes the fundamental parameter of storage medium from DNA to polysaccharides, which have different chemical properties that enable higher information density while maintaining stability. The polysaccharide structure allows for more states per molecule, increasing information capacity without sacrificing archival stability.
Solution Approach 2:
The patent employs composite material structures by combining polysaccharides with other materials to create a storage system that achieves both high information density and stability. The composite approach allows optimization of both parameters that cannot be achieved with a single material alone.
2Stability of the object's composition
If DNA encapsulation is used, then storage stability is improved, but read and write times increase
Solution Approach 1:
The patent extracts the encapsulation step from the DNA storage process, using polysaccharides that do not require encapsulation for stability. This eliminates the time-consuming encapsulation and decapsulation operations while maintaining storage stability through the inherent properties of polysaccharides.
Solution Approach 2:
The patent uses polysaccharides that can be rapidly synthesized and read without requiring long-term stable encapsulation structures. The shorter-lived but faster-accessible polysaccharide structure replaces the long-term stable but slow-accessible DNA encapsulation system.
3Quantity of substance
If DNA storage is used, then archival capacity is improved, but environmental impact increases
Solution Approach 1:
The patent replaces DNA with polysaccharides, which are biodegradable and environmentally friendly materials. This substitution eliminates the environmental harm associated with DNA storage while maintaining or improving archival capacity through the higher information density of polysaccharide structures.
Solution Approach 2:
The patent changes the chemical composition parameter from nucleic acid-based (DNA) to carbohydrate-based (polysaccharide) materials. This parameter change fundamentally alters the environmental impact profile while enabling higher storage capacity through the structural properties of polysaccharides.
Data Source
AI summary
One example method includes encoding data as a polysaccharide structure, synthesizing the polysaccharide structure to create polysaccharide storage media that comprises the data, and storing the polysaccharide storage media. The example method may also include receiving a read request directed to the polysaccharide storage media, mapping the polysaccharide structure to create a map in response to the read request, traversing the map of the polysaccharide structure to determine an X-base number, and obtaining the data by converting the X-base number to a binary form.
