Solution Overview

Problem

Counterfeit and pirated products pose a significant threat to consumer safety and economic loss, necessitating a software solution that provides immutable authenticity, provenance, and ownership tracking with unique key pairings that are difficult to duplicate.

Innovation Solution

A blockchain-based authentication system generates public and private keys for QR codes or NFC devices, using decentralized technology to manage product smart contracts, ensuring secure and transparent tracking of product ownership and transport history.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional authentication methods are used, then implementation is simple, but security against counterfeit products is insufficient

Engineering Contradiction:

Improveauthentication securityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a blockchain-based intermediary authentication system that mediates between manufacturers and consumers. The blockchain ledger acts as a neutral third party that verifies product authenticity without requiring direct trust between trading parties, thereby enhancing security while maintaining operational simplicity through standardized smart contract interactions.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical authentication systems (physical seals, holograms, manual verification) with a digital blockchain-based authentication mechanism. This substitution uses cryptographic key pairs and smart contracts to verify product authenticity, providing superior security and immutability while reducing the need for complex physical anti-counterfeiting features.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If immutable blockchain authentication is implemented, then product authenticity is guaranteed, but implementation complexity increases

Engineering Contradiction:

Improveauthenticity verificationVSAvoidimplementation ease

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent implements preliminary action by pre-generating cryptographic key pairs and embedding authentication credentials in products during manufacturing. The blockchain smart contracts are pre-configured with authentication logic, so that when products are authenticated later, the verification process is straightforward and requires minimal complex setup or manual configuration.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If decentralized blockchain technology is used, then tamper-proof tracking is achieved, but system overhead increases

Engineering Contradiction:

Improvetracking integrityVSAvoidcomputational overhead

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent extracts the computationally intensive consensus and validation operations from individual product authentication processes and centralizes them in the blockchain network. Individual product verification only requires lightweight cryptographic checks against the blockchain ledger, while the heavy lifting of maintaining immutability and consensus is handled by the distributed network, reducing overhead for each authentication event.

Inventive Principle:

Principle #2Taking out (Extraction)
