Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional shipment processing systems using QR codes are insecure, require a single QR code for transaction identification, lack interoperability, and rely on centralized databases that are prone to failures, bottlenecks, and limited accessibility, failing to provide seamless and secure transactions across multiple parties.

Innovation Solution

A blockchain-based system generates QR codes dynamically, incorporating biometric data and recording transactions on a shared immutable ledger, enabling secure, decentralized, and interoperable shipment processing without the need for mobile apps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a centralized database is used to store shipment transaction data, then data management and security control are simplified, but system reliability deteriorates due to single point of failure and hardware dependency

Engineering Contradiction:

Improvedata management complexityVSAvoidsystem reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system segments the centralized database into a distributed blockchain network where multiple nodes store copies of transaction data. Each node operates independently, eliminating the single point of failure while maintaining data accessibility across the network.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system creates multiple copies of transaction data across different nodes in the blockchain network. Instead of storing data in a single centralized database, each participant receives and stores a copy of the transaction record, ensuring data redundancy and system continuity even if individual nodes fail.

Inventive Principle:

Principle #26Copying

2Device complexity

If a centralized database is used for transaction storage, then data accessibility control is simplified, but transaction speed deteriorates due to network connectivity dependencies and bottlenecks

Engineering Contradiction:

Improvedata accessibility controlVSAvoidtransaction speed

Core Design Contradiction:

Device complexityVSSpeed

Solution Approach 1:

The system divides the centralized data access model into a distributed architecture where each node can independently read and process transactions locally. This segmentation eliminates network connectivity bottlenecks and reduces dependency on central server response times.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system pre-distributes transaction data and blockchain state information to multiple nodes before transactions occur. This preliminary distribution allows nodes to process transactions locally without waiting for real-time data retrieval from a central database, significantly improving transaction speed.

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If a single QR code is used to identify transactions, then system simplicity is maintained, but security deteriorates due to vulnerability to bad actors

Engineering Contradiction:

Improvesystem simplicityVSAvoidsecurity vulnerability

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The system segments the single QR code into multiple dynamic QR codes distributed across different blockchain nodes. Each QR code is time-limited and can be regenerated, making it difficult for bad actors to steal or reuse credentials. The segmentation of identification mechanisms enhances security while maintaining user-friendly interaction.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system transitions from static, permanent QR codes to dynamic, time-limited QR codes that can be regenerated. The QR codes change over time based on transaction state, making them resistant to theft and reuse. This dynamic approach maintains simplicity for users while dramatically improving security.

Inventive Principle:

Principle #15Dynamics

4Ease of manufacture

If conventional databases are used for storage, then implementation is straightforward, but data redundancy and privacy protection are insufficient

Engineering Contradiction:

Improveimplementation easeVSAvoiddata redundancy and privacy

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The system implements automatic copying of transaction data to multiple blockchain nodes, creating inherent data redundancy. Each node stores a complete copy of the transaction history, ensuring data persistence even if individual nodes or the entire network experience failures. This copying mechanism provides both redundancy and privacy through distributed storage.

Inventive Principle:

Principle #26Copying

AI summary

A system for an automated secured processing of shipments, including a processor of a shipment processing server node connected to at least one originating user node and to at least one target user node over a wireless network connection and a memory on which are stored machine-readable instructions that when executed by the processor, cause the processor to: receive a shipment transaction request from the at least one originating user node, the shipment transaction request comprising transaction parameters; create a shipment transaction based on the transaction parameters derived from the shipment transaction request; generate a QR code for the shipment transaction; send a link containing a verification request to the at least one target user node; responsive to the verification request, receive biometric capture data from the at least one target user node; regenerate the QR code for the shipment transaction to include the biometric capture data; and record the regenerated QR code on a blockchain ledger.
