Solution Overview

Problem

Existing resource transfer validation methods require in-person interactions, leading to inefficiencies and increased risks of delays and manual errors, particularly in certifying and transferring digital resources.

Innovation Solution

A system that digitally certifies resource transfers by generating an electronic proof document, temporarily locking resources in an intermediate account, and allowing transfers based on digital tokens and expiry times, enabling secure and efficient resource management without physical instruments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If in-person interactions are used for resource transfer validation, then security and trust are improved, but efficiency and productivity deteriorate due to delays and manual errors

Engineering Contradiction:
ImprovesecurityVSAvoidefficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the mechanical system of in-person physical interactions with a digital electronic system. Users can initiate and validate resource transfers through electronic interfaces without meeting physically, substituting the mechanical requirement for face-to-face verification with digital authentication and electronic proof documents.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary validation system that acts as a trusted third party between transferor and recipient. This system issues electronic proof documents that certify resource availability and transfer legitimacy, eliminating the need for direct in-person verification while maintaining security through a neutral mediator.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If digital certification is implemented, then ease of operation is improved, but device complexity increases due to intermediate accounts and electronic proof documents

Engineering Contradiction:
ImproveconvenienceVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the validation and certification functions from the user-operated devices and places them in a centralized validation system. This separates the complex certification logic from individual user devices, making the user interface simple while housing the complexity in the backend validation infrastructure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent creates a universal validation system that handles multiple functions: resource availability verification, electronic proof document generation, transfer certification, and expiry time management. This multi-functional system consolidates what would otherwise require multiple separate mechanisms into a single versatile platform.

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

3Reliability

If resources are temporarily locked in intermediate accounts, then reliability of transfer certification is improved, but loss of time occurs during the locking period

Engineering Contradiction:
Improvetransfer certificationVSAvoidtransfer duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent performs preliminary actions by locking resources in intermediate accounts before actual transfers occur. This advance preparation ensures resource availability is guaranteed when transfers are initiated, preventing delays caused by availability checks at the moment of transfer and streamlining the execution phase.

Inventive Principle:
Principle #10Preliminary action

AI summary

A computer-implemented method is disclosed. The method includes: receiving, via a computing device, a first request to digitally certify resources for transfer, the first request including an identifier of a first resource account, a recipient identifier, a first quantity of resources to certify, and an expiry time; causing a transfer of the first quantity of resources from the first resource account to a defined intermediate resource account; generating an electronic proof document associated with the digital certification of the resources, the electronic proof document being digitally signed; responsive to receiving, via the computing device, a second request to transfer the digitally certified resources: transmitting, to the recipient entity, a message comprising the electronic proof document and an indication of the expiry time; and processing transfer of the first quantity of resources from the intermediate resource account to the first resource account based on a response action of the recipient entity.
