Solution Overview

Problem

Conventional smart grid infrastructure faces challenges with data overload, leading to throughput issues and obsolete processing hardware due to the rapid growth of data being transmitted and processed, which cannot scale as quickly as the data generation rate.

Innovation Solution

Implementing a distributed processing method across a network of nodes, where each node executes stream functions on time series data to generate data streams, processing them in real-time and sharing the results, thereby breaking down complex processing into granular steps across the network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If centralized processing infrastructure is used to handle smart grid data, then data processing capability is improved, but infrastructure complexity and cost increase rapidly as data volume grows

Engineering Contradiction:
Improvedata processing capabilityVSAvoidinfrastructure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the centralized processing architecture into distributed edge computing nodes deployed throughout the smart grid infrastructure. Each edge node processes data locally, dividing the processing workload across multiple locations rather than concentrating it in a single centralized system, thereby reducing infrastructure complexity while maintaining processing capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a spatial dimension to data processing by deploying edge computing nodes at multiple physical locations within the smart grid. This transforms the processing architecture from a single-point centralized model to a distributed spatial network, allowing data to be processed closer to its source and reducing the burden on centralized infrastructure.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of information

If all smart meter data is transmitted to the back office for processing, then comprehensive data analysis is improved, but network traffic and throughput issues worsen

Engineering Contradiction:
Improvedata analysis completenessVSAvoidnetwork traffic load
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The patent extracts processing functions from the centralized back office and places them at the edge of the network where data is generated. Edge nodes perform local data processing, filtering, and aggregation, extracting only essential information for transmission to the back office. This reduces network traffic load while preserving the completeness of data analysis through distributed processing.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements preliminary data processing at the edge before data is transmitted to the back office. Edge nodes perform initial filtering, aggregation, and preprocessing of smart meter data, preparing it in advance for centralized analysis. This preliminary action reduces the volume of data requiring network transmission while ensuring comprehensive analysis capabilities are maintained at the back office.

Inventive Principle:
Principle #10Preliminary action

3Power

If centralized processing hardware is used, then processing power is improved, but hardware obsolescence occurs faster as data volume grows

Engineering Contradiction:
Improveprocessing powerVSAvoidhardware lifespan
Core Design Contradiction:
PowerVSDuration of action of stationary object

Solution Approach 1:

The patent segments processing power across multiple distributed edge nodes rather than concentrating it in centralized hardware. This distribution allows the system to scale by adding individual nodes as needed, preventing any single piece of hardware from becoming a bottleneck and extending the effective lifespan of the processing infrastructure through modular expansion.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent enables edge nodes to perform processing locally, making the system self-sufficient at the network edge. Each edge node independently handles data processing for its local area, reducing dependency on centralized processing hardware and allowing the system to scale without requiring continuous upgrades to central processing facilities.

Inventive Principle:
Principle #25Self-service

AI summary

Nodes within a wireless mesh network are configured to monitor time series data associated with a utility network, including voltage fluctuations, current levels, temperature data, humidity measurements, and other observable physical quantities. The nodes execute stream functions to process the recorded time series data and generate data streams. The node is configured to transmit generated data streams to neighboring nodes. A neighboring node may execute other stream functions to process the received data stream(s), thereby generating additional data streams. A server coupled to the wireless mesh network collects and processes the data streams to identify events occurring within the network.
