Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The real estate transaction process is inefficient, requiring extensive paperwork, face-to-face interaction, lack of technological capability for rapid legally-binding agreements, and lacks transparency and auditability, leading to high costs and variability in service provision.

Innovation Solution

A system integrating real-estate businesses, landlords, and clients through a cooperative platform using blockchain technology, enabling secure, automated offer generation and negotiation with dashboards for real-time tracking and communication, and secure digital wallets for document management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional hard-copy document preparation and filing is used, then legal binding and security are achieved, but time consumption and cost increase significantly

Engineering Contradiction:

Improvelegal binding and securityVSAvoidtime consumption

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical system of physical document handling (printing, signing, filing) with an electronic digital system. Documents are created, signed, and stored digitally through a computer-based platform, eliminating the need for physical paperwork while maintaining legal binding through electronic signatures and blockchain verification.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates digital copies of physical documents that can be instantly reproduced and distributed. Instead of handling unique physical originals, multiple identical digital copies can be generated and shared across the platform, accelerating the document workflow while preserving authenticity through cryptographic verification.

Inventive Principle:

Principle #26Copying

2Reliability

If face-to-face interaction is required for transactions, then personal verification and trust are established, but transaction speed and accessibility decrease

Engineering Contradiction:

Improvepersonal verification and trustVSAvoidtransaction speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent introduces a digital platform with blockchain technology as an intermediary that facilitates transactions between parties without requiring physical meeting. The system verifies identities, manages communications, and records agreements digitally, maintaining trust and verification capabilities while enabling remote participation and faster transaction completion.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If manual offer tracking and process monitoring is used, then agent control and flexibility are maintained, but transparency and auditability are reduced

Engineering Contradiction:

Improveagent controlVSAvoidtransparency and auditability

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent implements automated feedback mechanisms through the digital platform that provide real-time visibility into offer status and transaction progress. All parties can access their transaction information through the system, and blockchain technology creates an immutable audit trail that maintains transparency while agents retain operational control through the interface.

Inventive Principle:

Principle #23Feedback

4Adaptability or versatility

If multiple independent real estate websites operate separately, then service diversity and specialization are achieved, but information sharing and coordination efficiency decrease

Engineering Contradiction:

Improveservice diversityVSAvoidinformation sharing

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent creates a universal blockchain-based platform that can accommodate multiple real estate websites and service providers while enabling information sharing across them. The system maintains the diversity of individual services and websites but adds a layer of interoperability that allows offers, listings, and transaction data to be shared and coordinated across the entire network.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A transaction system has Internet-connected partner platforms which display webpages with an Offer-Now button initiating coded instructions to display an electronic input form enabling a person to configure a transaction offer, and an Internet-connected service enterprise providing the coded instructions to the partners, configured specifically to partner requirements. Upon the person activating the Offer Now button from a mobile device, a verification code is sent to the device, to be returned to verify the device, and offer input provided through the device and the electronic form is tracked to be saved as an offer for the transaction.
