Solution Overview

Problem

The real estate transaction process is resource-heavy, time-consuming, and inefficient due to the need for manual actions and coordination among various stakeholders, leading to inefficiencies and potential fraud.

Innovation Solution

A blockchain-based platform that securely tracks, monitors, and stores transaction data, utilizing self-sovereign identities and smart contracts to standardize and automate the process, ensuring transparency, fraud reduction, and efficient information sharing among participants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual coordination among multiple stakeholders is used to complete real estate transactions, then comprehensive task completion is achieved, but transaction time and resource consumption increase significantly

Engineering Contradiction:

Improvetransaction completionVSAvoidtransaction duration

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces manual coordination mechanisms with an automated digital platform that uses electronic workflows, digital signatures, and blockchain technology to orchestrate transactions among multiple stakeholders. This substitution eliminates the need for physical document exchange and manual communication, dramatically reducing transaction time while maintaining comprehensive task completion through systematic automation of all transaction steps.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The platform enables stakeholders to independently complete their own tasks through self-service portals where they can upload documents, review transaction details, apply digital signatures, and track progress without requiring constant intermediary coordination. This self-service capability reduces the time burden on intermediaries while ensuring all necessary tasks are completed systematically.

Inventive Principle:

Principle #25Self-service

2Reliability

If multiple intermediaries are involved in real estate transactions, then task completeness is ensured, but process complexity and resource requirements increase

Engineering Contradiction:

Improvetask completionVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the functions of multiple intermediaries (real estate agents, notaries, lawyers, government officials) into a single integrated digital platform. This consolidation allows all stakeholders to interact through one unified system rather than requiring separate coordination channels for each intermediary, reducing system complexity while maintaining comprehensive task completion through centralized workflow management.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The platform is designed as a universal system that can handle diverse transaction tasks (document verification, signature collection, regulatory compliance, fund transfer) through a single multi-functional interface. This universality eliminates the need for separate specialized systems for each intermediary function, simplifying the overall system architecture while ensuring all necessary tasks are accomplished.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If traditional document-based transaction records are used, then flexibility in handling diverse transactions is maintained, but security and fraud prevention are compromised

Engineering Contradiction:

Improvetransaction flexibilityVSAvoidsecurity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent replaces physical document-based record-keeping with a digital blockchain ledger that provides immutable, cryptographically secure transaction records. This substitution maintains flexibility through digital adaptability while dramatically enhancing security, as blockchain's distributed ledger technology prevents tampering and provides transparent audit trails for all transaction participants.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates digital copies of all transaction documents and stores them on the blockchain, replacing physical document handling. These digital copies maintain the flexibility needed for diverse transaction types while the blockchain infrastructure provides cryptographic verification and immutability, eliminating security vulnerabilities associated with physical document management.

Inventive Principle:

Principle #26Copying

AI summary

A computerized method for securing and performing a transaction, the method including receiving, at a computing system from a first party, a request to start the transaction; verifying the identity and a role for the first party; identifying, from the request, a transaction type and parties to the transaction; starting a workflow for the transaction based on the transaction type; sending, based on the workflow, requests for information to the parties to the transaction; receiving the information; and storing the information in a blockchain for the transaction.
