Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication mechanisms often require internet or cellular connections, leading to high power consumption and limited range, making them unsuitable for devices with small battery capacities or those needing long-range communication.
Innovation Solution
The use of LoRaWAN communication protocol for low-power, long-range authentication and device status inquiries, allowing devices to communicate without relying on internet or cellular networks and enabling communication over distances of up to 10 miles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Wi-Fi or cellular connections are used for authentication, then authentication can be performed, but power consumption increases significantly
Solution Approach 1:
The patent replaces traditional Wi-Fi or cellular authentication mechanisms with LoRaWAN-based authentication. This substitution uses low-power long-range wireless communication technology that consumes significantly less energy than conventional methods while maintaining authentication functionality, directly resolving the contradiction between authentication capability and power consumption.
Solution Approach 2:
The patent changes the communication protocol parameter from high-power protocols (Wi-Fi, cellular) to low-power protocols (LoRaWAN). This parameter change in the communication technology enables authentication to proceed with reduced power consumption, addressing the energy consumption issue while preserving authentication reliability.
2Use of energy by moving object
If Bluetooth or NFC protocols are used for authentication, then power consumption is reduced, but communication range is limited to short distances
Solution Approach 1:
The patent changes the communication range parameter by switching from short-range protocols (Bluetooth, NFC) to long-range LoRaWAN protocol. This parameter change enables communication over distances of up to 10 miles while maintaining low power consumption characteristics, resolving the contradiction between energy efficiency and communication range.
3Use of energy by moving object
If LoRaWAN protocol is used for authentication, then power consumption is reduced and range is extended, but device complexity increases
Solution Approach 1:
The patent implements a universal authentication mechanism using LoRaWAN that can be integrated into various device types (mobile devices, ATMs, vending machines, etc.). The protocol provides multi-functional capabilities including authentication, device status inquiry, and location-based services, reducing overall system complexity despite the advanced protocol requirements.
Data Source
AI summary
Device information may be obtained using LoRaWAN communications. A device information request may be generated and transmitted by a user device and include request parameters such as a device type for which information is desired, a type of information requested, a geographic range for the request, and the like and/or combinations thereof. Device information requests may also be propagated or repeated by intermediary devices to achieve the desired request range. Accordingly, a recipient device of the original request may propagate or repeat, using LoRaWAN, a request signal if it determines that the request range has not been met. If the request range has been met, the recipient device might not repeat the request.
