Solution Overview

Problem

Advanced Metering Infrastructure (AMI) networks face challenges in traffic management and collector configuration due to the large difference in scale between collectors and meters in gateway-based networks, which complicates traffic management and configuration.

Innovation Solution

Implementing a system with remotely configurable gateways, IP-based communications networks, and utility central facility servers that allow for multicast configuration of gateways, enabling efficient configuration and reconfiguration of multiple devices simultaneously, particularly for determining the extent of power or service outages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a gateway-based network is used instead of a collector-based network, then deployment flexibility and infrastructure costs are improved, but traffic management and configuration complexity increase significantly

Engineering Contradiction:
Improvedeployment flexibilityVSAvoidtraffic management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a gateway as an intermediary device between meters and the utility company's central system. This gateway aggregates data from multiple meters and manages local network traffic, thereby reducing the overall system complexity while maintaining deployment flexibility. The gateway acts as a mediator that handles configuration and traffic management locally, preventing these complexities from propagating to the central system.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the network into hierarchical levels: individual meters, local gateways, and the central utility system. Each segment operates semi-independently, with gateways handling local traffic management and configuration. This segmentation allows the system to maintain flexibility at the edge while managing complexity through distributed intelligence rather than centralized control.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If each gateway reads only a single meter, then configuration simplicity is improved, but productivity and coverage efficiency deteriorate

Engineering Contradiction:
Improveconfiguration simplicityVSAvoidmeters per gateway coverage
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent implements dynamic configuration capabilities where gateways can adapt their meter coverage assignments based on operational needs. The system allows gateways to dynamically add, remove, or reassign meters without requiring complete reconfiguration, thereby maintaining configuration simplicity while enabling flexible scaling of meters per gateway based on performance and coverage requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent employs preliminary configuration templates and pre-defined meter grouping strategies that simplify the initial setup process. By pre-configuring gateways with standard meter assignment patterns and coverage parameters, the system enables rapid deployment while maintaining the ability to adjust coverage capacity as needed, thus resolving the contradiction between configuration simplicity and productivity.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If remote configuration capability is added to gateways, then adaptability and response time to outages are improved, but device complexity and communication requirements increase

Engineering Contradiction:
Improveconfiguration adaptabilityVSAvoidgateway complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements feedback mechanisms where gateways automatically report their configuration status, operational metrics, and detected outages to the central system. This feedback loop enables the central system to remotely configure and reconfigure gateways based on real-time conditions without requiring complex manual intervention, thereby improving adaptability while managing device complexity through automated monitoring and control.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent enables gateways to perform self-configuration and self-diagnosis functions. The gateways can automatically detect outages, assess their own operational status, and apply configuration changes locally based on pre-defined rules and received instructions, reducing the need for complex centralized control while improving response time and adaptability to changing conditions.

Inventive Principle:
Principle #25Self-service
