Solution Overview

Problem

Current archival data storage methods, such as DNA storage, face limitations in information density, stability, and environmental requirements, which hinder their practical application due to high costs and slow read/write times.

Innovation Solution

The use of polysaccharides as a data storage medium, which offers higher storage capacity and stability, allowing for data encoding and decoding through polysaccharide structures that can be synthesized and read without requiring special storage conditions, utilizing techniques like Automated Glycan Assembly and Multi-Sequence Alignment for compression.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If DNA encapsulation in silica particles is used to maintain stability, then storage duration is improved, but information density deteriorates due to the 1-2 orders of magnitude sacrifice required for encapsulation structures

Engineering Contradiction:

Improvestorage durationVSAvoidinformation density

Core Design Contradiction:

Duration of action of stationary objectVSQuantity of substance

Solution Approach 1:

The patent changes the chemical composition parameters from DNA (4 states per unit) to polysaccharides with 16+ states per monosaccharide unit, achieving both long-term stability and high information density simultaneously by selecting a different chemical substrate with inherently superior properties

Inventive Principle:

Principle #35Parameter changes

2Reliability

If DNA encapsulation processes are implemented, then storage stability is improved, but manufacturing complexity increases due to layer by layer encapsulation requirements

Engineering Contradiction:

Improvestorage stabilityVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the encapsulation requirement entirely by selecting polysaccharides that inherently possess the desired stability properties without needing encapsulation structures, eliminating the complex layer-by-layer manufacturing process while maintaining storage reliability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses readily available polysaccharide materials that are chemically stable and do not require complex encapsulation, simplifying the manufacturing process while achieving the desired storage stability

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Quantity of substance

If DNA storage technology is used, then data storage capability is achieved, but cost increases due to special storage conditions and processing requirements

Engineering Contradiction:

Improvedata storage capabilityVSAvoidcost

Core Design Contradiction:

Quantity of substanceVSEase of manufacture

Solution Approach 1:

The patent replaces expensive DNA with inexpensive polysaccharide materials that can be synthesized through automated glycan assembly, dramatically reducing the cost of data storage while maintaining or improving storage capability through higher information density per unit mass

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

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 compressing the polysaccharide and storing the compressed data as a polysaccharide.
