Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If data is stored on a single cloud platform, then storage simplicity is improved, but data security and reliability deteriorate due to single-point failure risk

Engineering Contradiction:
Improvestorage simplicityVSAvoiddata security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent divides data into multiple data blocks and distributes them across multiple cloud platforms. Each cloud platform stores only a portion of the data, eliminating the single-point failure risk while maintaining storage simplicity through automated distribution mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a blockchain network as an intermediary layer that coordinates data distribution and storage across multiple cloud platforms. The blockchain manages metadata, tracks data locations, and enables recovery operations without requiring direct complex interactions between users and multiple cloud providers.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If data is distributed across multiple cloud platforms, then data security and reliability are improved, but management complexity worsens

Engineering Contradiction:
Improvedata securityVSAvoidmanagement complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The blockchain network serves as a centralized coordination layer that simplifies management of distributed data. It stores metadata about data blocks, tracks their locations across cloud platforms, and enables unified recovery operations, thereby reducing management complexity despite physical data distribution.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The blockchain network performs multiple functions including metadata storage, data location tracking, recovery coordination, and integrity verification. This multi-functional intermediary handles diverse management tasks through a single system, reducing overall complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If data is divided and distributed across multiple cloud nodes, then security against single-point failure is improved, but data retrieval complexity worsens

Engineering Contradiction:
Improvefailure resistanceVSAvoiddata retrieval
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The blockchain network acts as an intermediary that tracks the location of all data blocks across cloud platforms. When data retrieval is needed, the blockchain provides the necessary metadata and location information, enabling simple retrieval operations despite data being physically distributed across multiple nodes.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback mechanisms where the blockchain continuously tracks and updates data block locations across cloud platforms. This real-time information feedback enables the system to automatically route retrieval operations to the correct locations without user complexity.

Inventive Principle:
Principle #23Feedback

AI summary

This application provides a data management method, and the method includes: A client receives a backup plan configured by a user for to-be-backed-up data; the client divides the to-be-backed-up data into c data blocks based on a quantity of cloud nodes used for backup and a quantity of backup copies, and stores the c data blocks in n cloud nodes on multi-cloud platforms in a distributed manner, where for at least one data block in the c data blocks, the multi-cloud platforms store b backup copies of the at least one data block; and the client provides, for a blockchain network, metadata of the data stored on the multi-cloud platforms, so that the blockchain network encodes the metadata into a backup identifier, and stores the backup identifier, where the backup identifier is used to address the data stored on the multi-cloud platforms. In this method, cloud-chain convergence is performed with reference to features of the blockchain network of being decentralized, secure, and reliable, to improve security of multi-cloud backup data and eliminate a single-point security bottleneck in a conventional method.
