Gateway and Adapter Power Chaining for Long-Cable Device Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods of powering devices, such as antennas, are limited by the availability of traditional power sources, restricting their use in environments where these sources are not readily available, especially as wireless communications become prevalent.
Innovation Solution
A system that uses a gateway and adapter to provide power and data over a single cable, allowing multiple devices, including antennas, to be daisy chained together, enabling coverage over significant distances without the need for conventional power receptacles or batteries, with features like automatic detection, data storage, and remote power control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional power sources (wall receptacles or portable power supplies) are used to power devices, then devices can be powered reliably, but devices are limited to use only in environments where such power sources are available
Solution Approach 1:
The patent introduces a power distribution system using a gateway, adapters, and Power Over Ethernet (POE) cables as intermediaries to transfer power wirelessly between devices. Instead of requiring direct connection to wall receptacles, power is transmitted through the POE cable infrastructure, enabling devices to be powered in locations without traditional power sources.
Solution Approach 2:
The patent replaces the mechanical connection system (physical plugging into wall receptacles) with an electrical field-based power transmission system. Power is transmitted through the POE cable using electrical fields, eliminating the need for mechanical power outlets and enabling deployment in environments without traditional power infrastructure.
2Length of stationary object
If multiple devices are connected using a single cable in a daisy chain configuration, then power and data can be distributed over long distances, but voltage bounces can disrupt the system
Solution Approach 1:
The patent implements a power switch that is remotely triggered to sequentially activate devices in the daisy chain configuration. This preliminary action of controlled power activation prevents simultaneous power surges and voltage bounces that would occur if all devices were powered on at once, thereby maintaining system stability over long cable distances.
Solution Approach 2:
The system incorporates health monitoring and data communication capabilities that provide feedback about system status and power conditions. This feedback mechanism allows the gateway to detect and respond to voltage anomalies, adjusting power distribution to maintain reliability in extended daisy chain configurations.
