Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional access control systems are limited in their ability to securely and efficiently manage access across a wide range of devices, particularly in IoT environments, where physical access control is often not integrated or relies on external authentication, and devices are narrowly dedicated to their authorization functions.
Innovation Solution
The implementation of low-power wireless systems that enable secure access control through a network of low-power wireless devices, transceivers, and servers, allowing for the establishment of low-power wireless connections with on-board vehicle systems for diagnostics and reporting, as well as flexible access control topologies that include vehicle charging stations and various secure functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional access control systems are used, then authorization functions are provided, but the systems are narrowly dedicated to their authorization functions and lack integration with other device functions
Solution Approach 1:
The patent implements access control functionality within existing IoT devices rather than requiring separate dedicated access control readers. The system allows IoT devices to perform both their primary functions and access control authorization, eliminating the need for separate access control hardware and achieving multi-functionality.
Solution Approach 2:
The patent combines access control authorization capabilities with existing IoT devices by establishing wireless connections between IoT devices and on-board transceivers. This merging integrates authorization functions into the existing device ecosystem, reducing system complexity while maintaining versatility.
2Adaptability or versatility
If external authentication servers are used for IoT devices, then logical access control is provided, but physical access control is not integrated into the devices
Solution Approach 1:
The patent introduces an on-board transceiver as an intermediary component within IoT devices that enables direct wireless communication for access control authorization. This intermediary allows physical access control to be integrated into devices without requiring continuous connection to external authentication servers, reducing power consumption while maintaining access control functionality.
3Reliability
If dedicated access control readers are used, then authorization functions are provided, but the devices cannot perform other functions
Solution Approach 1:
The patent enables IoT devices to serve dual purposes: performing their primary specialized functions while simultaneously providing access control authorization capabilities. The on-board transceiver allows these devices to authenticate users or devices wirelessly without sacrificing their original functionality, achieving universality.

AI summary
Novel tools and techniques for low-power wireless for vehicle diagnostics and reporting are provided. A system includes a wireless charging station, a diagnostic server, a network device, a low-power wireless device, and a low-power wireless transceiver. The network device may be in communication with the diagnostic server. The low-power wireless device may include a processor, and non-transitory computer readable media including instructions executable by the processor to establish a low-power wireless connection, obtain on-board information from the vehicle via the low-power wireless connection, transmit the on-board information to the diagnostic server, and receive a report from the diagnostic server based on the on-board information.
