Solution Overview

Problem

The existing accommodation sharing systems face challenges in efficiently matching demand and supply for accommodations due to difficulties in establishing transactions that satisfy multiple conditions, such as location, date, and number of bedrooms, leading to reduced transaction likelihood and increased network resource usage.

Innovation Solution

An accommodation sharing device using a blockchain to generate unique content IDs (CIDs) and non-fungible tokens (NFTs) for securing possession rights, enabling secure and efficient sharing of accommodations by linking geographical coordinates and managing possession rights through a blockchain network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If accommodation sharing transactions are established by manually matching multiple conditions (location, date, bedrooms), then transaction accuracy can be maintained, but transaction efficiency and likelihood decrease significantly

Engineering Contradiction:
Improvetransaction accuracyVSAvoidtransaction efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the manual mechanical matching process with an automated electronic system using blockchain technology. The smart contract automatically compares accommodation supply data with demand requirements across multiple conditions (location, date, bedroom count) and executes transactions without human intervention, maintaining accuracy while dramatically improving efficiency

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

Solution Approach 2:

The patent introduces a blockchain-based smart contract as an intermediary between accommodation providers and seekers. This intermediary automatically facilitates matching by evaluating multiple conditions simultaneously and executing transactions when all criteria are met, resolving the contradiction between manual accuracy and automated efficiency

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If blockchain technology is implemented for secure possession right transfer, then transaction security and confidence between parties improve, but system complexity and implementation difficulty increase

Engineering Contradiction:
Improvetransaction securityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses NFTs (non-fungible tokens) as digital copies representing possession rights of physical accommodations. These tokenized copies can be securely transferred on the blockchain without moving the actual property, providing security through cryptographic verification while keeping the physical system simple and recognizable

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent segments the possession right transfer process into distinct blockchain operations: creating NFT tokens representing accommodation rights, storing them in a blockchain ledger, and transferring them between parties through smart contracts. This segmentation makes the complex blockchain implementation more manageable and modular

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If traditional accommodation sale services like Airbnb are used, then transaction convenience is improved, but the essence of sharing economy (mutual sharing without profit) is lost

Engineering Contradiction:
Improvetransaction convenienceVSAvoidsharing economy essence
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent inverts the traditional accommodation sale model by enabling users to both provide and seek accommodations equally. Instead of platforms taking cuts and creating profit-driven transactions, the system allows peer-to-peer mutual sharing where users can switch between being providers and seekers, preserving the sharing economy's core principle while maintaining convenience through automated matching

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

An electronic device according to an embodiment of the present disclosure that is an accommodation sharing device using a blockchain may include a communication module configured to perform open or closed communication with external electronic devices, a processor configured to control an operation of the communication module, and a memory operatively connected to the processor. The memory may include instructions. When the instructions are executed by the processor, the electronic device may generate a first CID including information on a first house or a room of the house provided by a first user. When the instructions are executed by the processor, the electronic device may generate a blockchain for a block of accommodations including specific tag information with which the first CID is able to be identified, in a pair if a security for securing provision of the first house or the room of the house is paid. When the instructions are executed by the processor, the electronic device may generate a blockchain for transferring a possession right of the first house or the room of the house in a form of a non-fungible token (NFT) and provides the NFT to the first user. In addition, various embodiments can be made.
