Solution Overview

Problem

Existing authentication mechanisms often require high power consumption and short range communication protocols, limiting their usability in devices with smaller battery capacities and sizes, such as wearables, for tasks like transactions and device authentication.

Innovation Solution

Implementing the low power, long range LoRaWAN communication protocol for electronic communications, which allows devices to perform transactions and authentication without relying on Internet or cellular connectivity, using LoRaWAN signals with user-specific or transaction-specific information to verify identities and process transactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If Wi-Fi or cellular connections are used for authentication, then communication reliability is improved, but power consumption increases

Engineering Contradiction:

Improveauthentication reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent changes the communication parameter from high-power Wi-Fi/cellular to low-power Bluetooth/NFC, achieving both authentication reliability and reduced power consumption by selecting appropriate communication protocols for different scenarios

Inventive Principle:

Principle #35Parameter changes

2Use of energy by moving object

If Bluetooth or NFC is used for communication, then power consumption is reduced, but communication range is limited

Engineering Contradiction:

Improvepower consumptionVSAvoidcommunication range

Core Design Contradiction:

Use of energy by moving objectVSLength of moving object

Solution Approach 1:

The patent segments the authentication process into two stages: first using Bluetooth/NFC for initial device pairing and setup, then using QR code visual recognition for distance-independent authentication, thereby achieving both low power consumption and extended communication range

Inventive Principle:

Principle #1Segmentation

3Length of moving object

If QR code visual recognition is used for authentication, then communication range is extended, but user operation complexity increases

Engineering Contradiction:

Improvecommunication rangeVSAvoiduser operation ease

Core Design Contradiction:

Length of moving objectVSEase of operation

Solution Approach 1:

The patent introduces a camera as an intermediary medium that captures the QR code and automatically transmits authentication data, eliminating the need for manual data entry and simplifying the user operation while maintaining extended communication range

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Transactions may be performed using a mobile device such as a user-wearable device using LoRaWAN protocol to minimize power consumption while maximizing communication range. Transaction information may be stored in the user-wearable device and transmitted to a transaction processing device using LoRaWAN communications. Transaction information may include user-specific information, payment information, merchant information, product information, user preference information and the like. In some instances, the only communication interface (or wireless communication interface) provided in the mobile device is a LoRaWAN communication interface.
