Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Mesh networks, such as Mesh Wi-Fi, suffer from packet forwarding delays and reduced transmission rates, making them unsuitable for high immediacy networks, and excessive nodes can degrade bandwidth capacity.

Innovation Solution

A method that utilizes Ultra-Wideband (UWB) devices to dynamically reconfigure routing paths by detecting UWB devices and calculating optimal transmission paths based on bandwidth and distance weights, guiding clients to move closer to selected UWB devices for improved data transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If packets are forwarded through multiple router nodes in a mesh network, then the network can maintain connectivity and bypass damaged nodes, but the transmission delay increases significantly

Engineering Contradiction:

Improvenetwork connectivityVSAvoidtransmission delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent introduces UWB devices as intermediary elements that establish direct communication paths between clients and routers, bypassing the need for packets to traverse multiple mesh router nodes. The UWB device acts as a mediator that enables direct data transmission while maintaining network connectivity, thus reducing transmission delay without sacrificing reliability

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the network communication into two distinct paths: control plane communication that maintains mesh network connectivity and reliability, and data plane communication that uses direct UWB links for low-latency transmission. This segmentation allows the system to achieve both high reliability and low delay by routing different types of traffic through optimized paths

Inventive Principle:

Principle #1Segmentation

2Reliability

If more router nodes are added to a mesh network, then network coverage and connectivity improve, but the transmission rate and bandwidth capacity decrease

Engineering Contradiction:

Improvenetwork coverageVSAvoidtransmission rate

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

UWB devices serve as intermediaries that enable direct peer-to-peer communication between clients and the network, eliminating the need for data to traverse multiple router nodes. This direct link approach maintains network coverage through the mesh structure while achieving high transmission rates comparable to wired connections

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent adds a spatial dimension to network communication by using UWB technology's precise location awareness to establish direct line-of-sight or near-line-of-sight paths. This dimensional approach allows data to travel the most direct physical path rather than following the logical mesh routing structure, thereby maintaining coverage while maximizing transmission rate

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A transmission path improving method in a mesh network is disclosed. General transmission paths connecting to each of routers and Ultra-Wideband (UWB) transmission paths connecting to each of UWB devices are calculated. If a client is located within a detection range of a UWB device, an optimal transmission path relating to the UWB device is selected from the UWB transmission paths and the optimal transmission path is transmitted to the client.
