Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional systems lack functionality for securely authenticating products, transferring ownership, managing insurance, preventing theft, and tracking products in primary and secondary markets, while failing to allow producers to gather data and communicate with consumers regarding secure, traceable digital and physical assets.

Innovation Solution

A system utilizing Near Field Communication (NFC) tags and blockchain technology to authenticate products, record transactions, and manage ownership, insurance, and theft prevention, enabling secure product tracking and data exchange among users and brand managers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional authentication systems are used, then product verification is possible, but security against counterfeiting and theft is insufficient

Engineering Contradiction:

Improveproduct authentication reliabilityVSAvoidcounterfeit and theft risks

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces NFC tags as intermediary devices attached to physical products, which store unique identifiers and enable secure communication between the product and authentication systems. This intermediary layer prevents direct copying or counterfeiting since the NFC tag is physically integrated with the product and requires proximity-based communication

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces conventional mechanical or database-based authentication systems with blockchain technology, which provides a decentralized, immutable ledger for recording product provenance and ownership. This substitution eliminates single points of failure and makes the system resistant to hacking and manipulation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If comprehensive product tracking and ownership management functionality is added, then product security and brand utility are enhanced, but system complexity increases

Engineering Contradiction:

Improveproduct tracking and ownership management capabilityVSAvoidsystem architecture complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal platform that handles multiple functions including authentication, ownership transfer, insurance management, and analytics through a single integrated system. The blockchain ledger serves as a universal data structure that can store diverse information types, while smart contracts provide reusable templates for different business logic scenarios

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent segments the system into distinct modular components: NFC tags for physical product identification, smart contracts for business logic automation, and a blockchain ledger for immutable record-keeping. This segmentation allows each component to be developed, deployed, and updated independently, reducing overall system complexity

Inventive Principle:

Principle #1Segmentation

3Loss of information

If blockchain technology is implemented for secure transaction recording, then data integrity and traceability are improved, but processing time and computational resources increase

Engineering Contradiction:

Improvedata integrity and traceabilityVSAvoidtransaction processing time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent extracts only the essential authentication data (unique product identifiers and ownership information) onto the blockchain, while storing detailed product information and analytics locally or in conventional databases. This selective extraction minimizes blockchain data storage requirements and speeds up transaction processing while maintaining data integrity for critical information

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A method includes receiving, by an application executing on a first computing device, from an NFC reader, a unique identifier of an NFC tag. A second computing device stores an identification of the product and the unique identifier of the NFC tag in a blockchain. The second computing device receives, from a third computing device, a request for a determination of authenticity of the NFC tag. The second computing device requests, from the blockchain, an indication of whether the unique identifier of the NFC tag is stored in association with the identification of the product and an indication of ownership. The second computing device receives confirmation that the unique identifier of the NFC tag is stored in association with the identification of the product and the indication of ownership. The second computing device provides, to the third computing device, the confirmation.
