Solution Overview

Problem

Existing data file transfer balancing and control systems rely on third parties, which increase development time, introduce application design complexity, and add an additional point of failure due to proprietary systems and lack of tamper-proofness.

Innovation Solution

A distributed database, such as a blockchain, is used to facilitate peer-to-peer data file transfers, enabling near-instant logging and validation of data file transfers through smart contracts that compare hashes for accuracy, eliminating the need for third-party intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a third party intermediary is used for data file transfer balancing and control, then validation and audit capabilities are provided, but development time increases and application design complexity increases

Engineering Contradiction:

Improvevalidation capabilityVSAvoidapplication design complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a blockchain-based intermediary that provides validation and audit capabilities without requiring integration with proprietary third-party systems. The blockchain acts as a neutral mediator that both sending and receiving systems can interact with using standard protocols, thereby maintaining reliability while reducing application design complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The blockchain platform provides multiple functions including validation, auditing, timestamping, and consensus verification through a single universal system. This eliminates the need for separate proprietary validation systems from different third parties, reducing both development time and application design complexity while maintaining comprehensive validation capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If a third party intermediary is used for data file transfer balancing and control, then validation capabilities are provided, but development time increases

Engineering Contradiction:

Improvevalidation capabilityVSAvoiddevelopment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The blockchain system performs preliminary validation and timestamping actions automatically as part of the transaction process. By pre-establishing consensus mechanisms and validation rules on the blockchain, the system eliminates the need for time-consuming integration with multiple third-party validation systems during project development.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If a third party intermediary is used for data file transfer balancing and control, then central authority for balancing and control is provided, but tamper-proofness is reduced

Engineering Contradiction:

Improvecentral authority controlVSAvoidtamper-proofness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The blockchain serves as a decentralized intermediary that provides central authority control through consensus mechanisms while simultaneously ensuring tamper-proofness through cryptographic hashing and distributed ledger technology. The blockchain's immutable structure prevents tampering while its consensus protocol maintains centralized coordination.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system changes the fundamental parameters of trust and validation from reliance on proprietary third-party systems to cryptographic proof and consensus validation. This parameter change enables both central authority control through consensus and tamper-proofness through the immutable blockchain structure.

Inventive Principle:

Principle #35Parameter changes

4Reliability

If proprietary third party systems are used, then balancing and control validation is achieved, but time to market increases

Engineering Contradiction:

Improvebalancing and control validationVSAvoidtime to market

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The blockchain platform provides universal validation capabilities that work across different applications and industries through standardized interfaces. This eliminates the need to develop and integrate with multiple proprietary third-party systems for different projects, significantly reducing time to market while maintaining comprehensive balancing and control validation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A balance and control system may write a data file transfer confirmation from a transmitter system to a blockchain in response to the transmitter system transmitting a data file to a receiver system with the confirmation including a transmitter system address, a receiver system address, and a first hash of the data file. The system may also write a data file transfer acknowledgement from a receiver system to the blockchain with the acknowledgement including the transmitter system address, the receiver system address, and a second hash of the data file. The blockchain may execute a smart contract to compare the first hash of the data file to the second hash of the data file to identify an out-of-balance file transfer event. A monitoring device of the B&C system may read the out-of-balance file transfer event from the blockchain.
