Solution Overview

Problem

The existing accommodation sharing systems face challenges in efficiently matching demand and supply due to difficulties in establishing transactions that satisfy various conditions such as location, date, and number of bedrooms, leading to a lack of confidence in possession right transfers, especially for long-distance accommodations, and inefficiencies in network resource usage.

Innovation Solution

An accommodation sharing device utilizing a blockchain to generate unique content IDs, blockchains for possession right transfers as non-fungible tokens, and door lock devices with possession right encryption codes to facilitate secure and efficient sharing of commercial accommodations and traveler rooms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional accommodation sharing systems are used to match demand and supply, then transaction establishment is attempted, but the difficulty in satisfying various conditions (location, date, number of bedrooms) leads to failed transactions and lack of confidence in possession right transfers

Engineering Contradiction:
Improveconfidence in possession right transferVSAvoidcomplexity of matching conditions
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a blockchain system as an intermediary between accommodation providers and users. The blockchain stores and verifies possession right transfer information, acting as a trusted mediator that ensures reliable transactions without requiring complex conditional matching between parties. This resolves the contradiction by providing reliability through the blockchain intermediary while simplifying the transaction process.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates digital copies of possession rights in the form of blockchain records and NFTs (non-fungible tokens). These digital representations allow for secure transfer and verification of accommodation rights without physically transferring the actual property. This copying mechanism enables reliable possession right transfer while avoiding the complexity of direct conditional matching between parties.

Inventive Principle:
Principle #26Copying

2Measurement precision

If accommodation sharing transactions are established with multiple conditions (location, date, bedrooms), then matching accuracy is improved, but the difficulty of accomplishing transactions increases when any condition is not satisfied

Engineering Contradiction:
Improveprecision of matching conditionsVSAvoidtransaction accomplishment rate
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent segments the accommodation sharing system into independent blockchain blocks, each representing a specific accommodation unit with its own conditions and possession rights. This segmentation allows individual units to be matched and transferred independently, improving transaction accomplishment rates while maintaining precise condition matching for each segment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary actions by pre-registering accommodation information, conditions, and possession rights in the blockchain before actual transactions occur. This preliminary structuring of data allows for efficient matching and quick transaction execution, improving productivity while maintaining measurement precision through pre-validated conditions.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If blockchain technology is used for possession right transfer, then security and reliability are improved, but network resource usage increases

Engineering Contradiction:
Improvesecurity of possession right transferVSAvoidnetwork resource consumption
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent extracts only the essential possession right transfer information into the blockchain, rather than storing complete accommodation data or transaction histories. By taking out only the critical elements needed for secure transfer verification, the system maintains high reliability while minimizing network resource consumption.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies different levels of detail to different parts of the blockchain structure. Critical possession right information is stored with high fidelity on the blockchain for security, while less critical data is handled locally or with reduced verification. This local quality approach maintains security where needed while reducing overall network resource usage.

Inventive Principle:
Principle #3Local quality

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.
