Solution Overview

Problem

Utility network nodes are limited to communicating via specific network modes (mobile, star, or mesh) and cannot adaptively switch between them based on changing conditions such as infrastructure costs, power supply, and RF performance, leading to suboptimal data transmission costs.

Innovation Solution

Nodes are capable of intelligently switching between multiple communication modes (mesh, star, mobile, and cellular direct connect) based on a 'read cost' factor, prioritizing modes such as mesh, star, and mobile, and adjusting parameters like transmit power and error correction to minimize costs, and can re-evaluate modes during network outages for self-healing and contingency reading.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If nodes are configured for a specific network mode (mobile, star, or mesh), then communication reliability is improved for that mode, but adaptability to changing network conditions deteriorates

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidadaptability to network conditions
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The node is designed with multi-functional communication capabilities, incorporating multiple communication modules (mobile network module, star network module, mesh network module) that enable it to operate in different network modes. This universal design allows the node to adapt to various network conditions while maintaining reliable communication in each specific mode through dedicated hardware and protocol stacks.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The node implements dynamic mode switching capability through a network mode determination module that continuously evaluates current network conditions (signal strength, network availability, power status) and automatically selects the optimal communication mode. This dynamic adaptation resolves the contradiction by allowing the node to maintain reliability in the currently selected mode while simultaneously adapting to changing conditions through real-time mode transitions.

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If nodes use fixed network infrastructure (star or mesh), then infrastructure costs are reduced, but flexibility in communication paths deteriorates

Engineering Contradiction:
Improveinfrastructure costVSAvoidflexibility in communication paths
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The node implements dynamic path selection by evaluating multiple communication modes (mobile, star, mesh) and switching between them based on real-time conditions. When infrastructure costs are a constraint, the node can dynamically select mobile mode for direct communication without infrastructure, or switch to star/mesh modes when infrastructure is available and cost-effective, thus achieving both cost efficiency and path flexibility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The node acts as an intelligent intermediary that mediates between different communication paradigms. It can function as an endpoint in mobile mode, as a leaf node in star mode, or as a routing node in mesh mode, adapting its role based on network conditions. This intermediary capability allows seamless transition between infrastructure-dependent and infrastructure-independent communication paths.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of information

If nodes transmit data continuously, then data freshness is improved, but power consumption increases

Engineering Contradiction:
Improvedata freshnessVSAvoidpower consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The node implements periodic data transmission with configurable intervals, transitioning from continuous transmission to time-based periodic transmission. The system monitors data changes and transmits only when necessary or at scheduled intervals, significantly reducing power consumption while maintaining acceptable data freshness through event-driven and time-driven transmission strategies.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The node dynamically changes transmission parameters (transmission power, data rate, interval) based on network conditions and data priority. For non-critical data, it uses lower power settings and longer intervals, while for critical data or poor network conditions, it increases transmission frequency and power, thus optimizing the balance between data freshness and power consumption through adaptive parameter adjustment.

Inventive Principle:
Principle #35Parameter changes

AI summary

A node may be configured for operation in an intelligent network environment, wherein the node communicates via different modes of communication. The node selects a first mode of communication (e.g., mesh network mode). The node communicates via the first mode of communication. In response to determining a first condition (e.g., interference), the node selects a second mode of communication. The node then communicates via the second mode of communication. In response to determining a second condition (e.g., interference ceases), the node selects the first mode of communication and communicates via the first mode of communication.
