Solution Overview

Problem

Mesh networks are expensive due to the high cost of infrastructure nodes, such as mesh-enabled routers and satellite devices, which inhibits their adoption despite offering better coverage than traditional wireless networks.

Innovation Solution

Repurpose consumer electronic devices, such as mobile phones and tablets, as nodes in mesh networks by installing a management platform that allows them to function as secondary access points, extending coverage at a lower cost.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If specialized infrastructure nodes (mesh-enabled routers and satellite devices) are used to create mesh networks, then network coverage and reliability are improved, but device cost increases significantly

Engineering Contradiction:

Improvenetwork coverageVSAvoiddevice cost

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent enables consumer electronic devices to perform multiple functions - their original purpose plus serving as mesh network infrastructure nodes. By installing mesh networking software on devices like smartphones and tablets, these devices gain the ability to relay data and extend network coverage, eliminating the need for dedicated expensive mesh hardware in many cases.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Existing consumer electronic devices with sufficient processing power and battery capacity are leveraged to provide mesh networking services. The devices essentially serve themselves by utilizing their existing hardware resources (CPU, radio, battery) to contribute to network infrastructure, rather than requiring separate specialized equipment.

Inventive Principle:

Principle #25Self-service

2Quantity of substance

If traditional routers and range extenders are used, then device cost is reduced, but network coverage and reliability deteriorate

Engineering Contradiction:

Improvedevice costVSAvoidnetwork coverage

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The patent changes the operational parameters of consumer electronic devices by installing and configuring mesh networking software. This software transformation enables ordinary devices to operate at mesh network performance levels, effectively changing their functional capabilities without altering their physical hardware parameters.

Inventive Principle:
