Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional monolithic blockchain structure is used, then security is improved through cryptographic linking of all transactions, but computational intensity and storage requirements increase making it unsuitable for IoT devices

Engineering Contradiction:

ImprovesecurityVSAvoidcomputational intensity

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent divides the monolithic blockchain into multiple separate blockchains, each dedicated to specific functions or transaction types. This segmentation allows IoT devices to participate in only relevant chains, reducing computational burden while maintaining security through cryptographic linking between chains.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent extracts and separates storage-intensive transaction data from the core blockchain structure. Only essential verification data and cryptographic hashes are retained in the blockchain, while full transaction details are stored externally, dramatically reducing storage requirements for IoT devices.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If a conventional monolithic blockchain structure is used, then security is improved through cryptographic linking of all transactions, but storage requirements increase making it unsuitable for IoT devices

Engineering Contradiction:

ImprovesecurityVSAvoidstorage requirements

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses cryptographic hashes and references as simplified copies of full transaction data. Instead of storing complete transaction records, the system stores compact hash representations that verify authenticity without requiring proportional storage space.

Inventive Principle:

Principle #26Copying

3Reliability

If a single blockchain structure is used, then transaction verification is comprehensive, but time to authenticate transactions increases preventing real-time processing

Engineering Contradiction:

Improvetransaction verificationVSAvoidtime to authenticate transactions

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent divides the verification process across multiple specialized blockchains, each optimized for specific transaction types. This allows parallel verification of different transaction categories simultaneously, reducing overall authentication time while maintaining comprehensive verification through inter-chain cryptographic links.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements pre-computed cryptographic hashes and verification data that are prepared in advance and stored in the blockchain structure. When a transaction needs verification, the pre-computed data is immediately available for rapid comparison, eliminating the need for time-consuming real-time computations.

Inventive Principle:

Principle #10Preliminary action

4Stability of the object's composition

If a conventional blockchain architecture is used, then data integrity is maintained through immutable chaining, but adaptability to code changes and scaling is reduced

Engineering Contradiction:

Improvedata integrityVSAvoidflexibility to code changes

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent creates multiple independent blockchain instances that can be developed, modified, and scaled separately. Each chain can undergo code changes and upgrades without affecting others, maintaining data integrity through cryptographic verification while enabling flexible adaptation and continuous deployment.

Inventive Principle:

Principle #1Segmentation

Data Source

PatentUS11848939B2System and method for managing and securing a distributed ledger for a decentralized peer-to-peer network

Publication Date: 2023.12.19 SMARTAXIOM INC

AI summary

The present disclosure relates to a method and system for managing and securing a distributed ledger for a decentralized peer-to-peer (p2p) network. The method receives an encrypted block and a group key generated by at least one peer node on the p2p network, wherein each peer node is IoT device and determines a virtual device block in a device chain on verifying the unique device ID, and address of a corresponding event chain associated with the virtual device block. Further, the method generates a transaction ID for a new transaction using the unique ID of the virtual device block and determines a valid event block in the event chain associated with the virtual device block for storing the new transaction and associated transaction ID. Further, the method updates the distributed ledger with the valid event block upon verification by one or more peer IoT devices of the p2p network.
