Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack a comprehensive method to store and link various information related to real vehicles, failing to provide a seamless integration of vehicle data with blockchain technology and NFTs.
Innovation Solution
A method and system that utilize NFTs to store and link various information related to real vehicles by creating a hash value based on user and vehicle information, issuing an NFT on a blockchain, and enabling NFT inquiries, transactions, and metadata modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional methods are used to store vehicle information, then the system is simple and easy to implement, but the information cannot be securely linked and verified across different systems
Solution Approach 1:
The patent introduces a blockchain as an intermediary layer between traditional vehicle information systems and digital verification systems. The blockchain serves as a mediator that securely stores hashed vehicle information and enables verification without requiring direct integration of complex systems, thus improving reliability while managing complexity through a dedicated intermediary infrastructure.
Solution Approach 2:
The patent creates a digital copy of vehicle information in the form of an NFT (non-fungible token) that contains a hash value of the vehicle data. This digital copy can be verified and transferred across different systems without modifying the original information, enabling secure linkage and verification while maintaining system simplicity through the use of standardized digital copying mechanisms.
2Reliability
If vehicle information is stored on-chain, then verification and uniqueness are guaranteed, but storage capacity and data flexibility are limited
Solution Approach 1:
The patent extracts large volumes of vehicle information (such as maintenance records, accident histories, and specification data) from the blockchain and stores them in off-chain databases or cloud storage systems. Only the critical verification data (hashed information and ownership metadata) remains on-chain, enabling reliable verification while providing virtually unlimited storage capacity for comprehensive vehicle data.
Solution Approach 2:
The patent uses the blockchain as an intermediary verification layer rather than a direct storage solution. The blockchain verifies ownership and data integrity through hash values, while off-chain storage systems handle the actual data storage, combining the verification strengths of on-chain technology with the capacity of off-chain storage systems.
3Reliability
If NFT metadata is fixed at issuance, then uniqueness and security are maintained, but adaptability and information updates are restricted
Solution Approach 1:
The patent implements a dynamic NFT metadata system where the metadata can be updated and modified after issuance. The NFT structure allows for flexible metadata updates to reflect changes in vehicle information, ownership status, or additional data, while maintaining the security and uniqueness guarantees of the blockchain through immutable hash values and controlled modification protocols.
Solution Approach 2:
The patent segments the NFT into fixed components (ownership information, hash value) that maintain security and uniqueness, and flexible components (metadata) that can be updated. This segmentation allows the core verification data to remain immutable while enabling adaptable metadata updates, combining security with versatility through structured data separation.
4Loss of information
If comprehensive vehicle data is collected and stored, then information completeness is improved, but system complexity and data management difficulty increase
Solution Approach 1:
The patent segments vehicle data management into distinct components: critical verification data stored on-chain with the NFT, comprehensive but non-critical data stored off-chain in organized databases, and structured metadata linking both layers. This segmentation enables comprehensive information collection while managing complexity through clear data organization and separation of concerns.
Solution Approach 2:
The patent uses the blockchain as an intermediary that organizes and verifies data relationships rather than storing all data directly. The blockchain manages the linkage between vehicle information, ownership records, and metadata through hash values and references, simplifying data management complexity while maintaining information completeness through the structured intermediary layer.

AI summary
Disclosed is a service providing method based on a non-fungible token (NFT), which may include creating, by a system server, a hash value based on user information for a vehicle, vehicle unique information, and vehicle information, issuing, by a blockchain main net, an NFT corresponding to the vehicle by using the user information, the vehicle information, and the hash value, and performing an NFT inquiry, an NFT transaction, and metadata modification of the NFT between the blockchain main net and any personal terminal.
