Solution Overview

Problem

Existing infrastructure maintenance and repair processes are inefficient during transient environmental conditions, leading to prolonged recovery times and significant resource allocation, as current methods do not effectively monitor or predict damage to utility grid elements.

Innovation Solution

A predictive outage service that utilizes weather information, geographic location data, past grid performance, topology, and social feeds to forecast when and where outages will occur by learning the characteristics of utility system elements through a clustering system and flow simulation, integrating sensors and machine learning for real-time data interpretation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional reactive maintenance methods are used during transient environmental conditions, then infrastructure integrity can be maintained through post-event repair, but recovery time extends for long periods and significant resources are allocated

Engineering Contradiction:
Improveinfrastructure integrityVSAvoidrecovery time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by predicting outages before they occur using sensor data and machine learning models. When the predictive model detects conditions indicating an impending outage, the system proactively dispatches maintenance personnel and resources to the predicted location, enabling preventive repair before the actual failure occurs. This resolves the contradiction by maintaining infrastructure integrity through advance intervention while minimizing recovery time through pre-positioned resources.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously collects sensor data from the infrastructure and feeds it back to the predictive model, which updates its predictions in real-time. This feedback loop enables the system to detect early signs of potential failures and adjust maintenance dispatch accordingly. The feedback mechanism resolves the contradiction by providing continuous monitoring that maintains infrastructure integrity while enabling timely, data-driven decisions that reduce recovery time.

Inventive Principle:
Principle #23Feedback

2Reliability

If traditional reactive maintenance methods are used during transient environmental conditions, then infrastructure integrity can be maintained through post-event repair, but significant resources such as personnel and equipment are heavily allocated

Engineering Contradiction:
Improveinfrastructure integrityVSAvoidresource allocation
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

By predicting outages in advance, the system enables targeted deployment of maintenance resources only to locations and times where failures are predicted to occur. This prevents the need to maintain large standing reserves of personnel and equipment, as resources are efficiently allocated based on predictive insights rather than reactive responses to widespread failures. The principle resolves the contradiction by maintaining infrastructure integrity through focused preventive maintenance while reducing overall resource allocation through intelligent scheduling.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The predictive maintenance system enables the infrastructure to effectively monitor and report its own condition through embedded sensors and automated anomaly detection. This self-service capability reduces the need for extensive human monitoring and resource deployment, as the system automatically identifies at-risk assets and triggers appropriate maintenance responses. The principle resolves the contradiction by maintaining infrastructure integrity through automated self-monitoring while reducing the quantity of human resources required.

Inventive Principle:
Principle #25Self-service

3Loss of time

If sensor-based predictive systems are implemented, then recovery time and resource allocation are reduced through accurate outage prediction, but device complexity increases

Engineering Contradiction:
Improverecovery timeVSAvoidsystem complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The predictive maintenance platform serves multiple functions: it collects sensor data, processes signals, runs predictive analytics, dispatches maintenance resources, and monitors outcomes. By consolidating these diverse functions into a single multi-functional system, the patent reduces overall complexity compared to having separate specialized systems for each function. The principle resolves the contradiction by enabling accurate outage prediction through an integrated platform that manages complexity internally while delivering simplified external interfaces and reduced recovery times.

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

Solution Approach 2:

The system introduces an intermediary predictive analytics layer between the raw sensor data and the maintenance dispatch decision. This intermediary layer processes and interprets sensor signals, translating complex physical measurements into actionable predictions about future failures. The intermediary resolves the contradiction by handling the complexity of data processing and pattern recognition internally, thereby enabling accurate outage prediction while presenting a simplified decision-making interface to maintenance operations.

Inventive Principle:
Principle #24Intermediary (Mediator)
