Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If distributed sensors and custom algorithms are used for full system monitoring, then diagnostic capability is improved, but implementation cost and complexity increase

Engineering Contradiction:
Improvediagnostic capabilityVSAvoidimplementation complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies universality by creating a single integrated monitoring system that can diagnose multiple different power system components (generators, transformers, motors, etc.) using one platform. The system uses universal sensors and algorithms that adapt to different equipment types, eliminating the need for separate custom monitoring systems for each component while maintaining high diagnostic capability.

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

Solution Approach 2:

The patent employs copying by using sensor data and signal patterns from one equipment type to create diagnostic models that can be applied to similar equipment. The system learns from training data and creates reusable diagnostic algorithms that can be copied across different power system components, reducing implementation complexity while preserving diagnostic accuracy.

Inventive Principle:
Principle #26Copying

2Measurement precision

If extensive data management and compute-intensive training are used, then classification accuracy is improved, but scalability deteriorates

Engineering Contradiction:
Improveclassification accuracyVSAvoidscalability
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies segmentation by dividing the data processing workflow into distinct stages: data collection, training phase, and deployment phase. During training, extensive data is processed to create accurate classification models, but once trained, the models are deployed to edge devices where they operate with minimal data processing requirements. This segmentation allows high classification accuracy to be achieved during training while maintaining scalability during deployment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary action by performing compute-intensive data training and model development beforehand, before deployment to field equipment. The system pre-processes extensive training data and creates finalized classification models that can then be deployed to various power system components without requiring ongoing extensive computational resources, thereby enabling scalability across multiple devices.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If equipment-specific monitoring solutions are implemented, then diagnostic accuracy for specific equipment is improved, but adaptability to different equipment types deteriorates

Engineering Contradiction:
Improvediagnostic accuracyVSAvoidequipment compatibility
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies universality by designing a monitoring platform that can diagnose multiple different power system equipment types using a single system. The platform uses universal sensors and adaptive algorithms that can be configured for different equipment types (generators, transformers, motors, etc.) while maintaining high diagnostic accuracy for each specific equipment type through targeted training data.

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

4Quantity of substance

Solution Approach 1:

The patent implements preliminary action by using the monitoring system to predict equipment failures before they occur. The system analyzes sensor data and classification models to identify early signs of equipment degradation, allowing maintenance to be scheduled in advance. This proactive approach reduces unexpected downtime while optimizing resource requirements by performing maintenance only when predicted to be necessary.

Inventive Principle:
