Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If deep learning is applied to machine condition monitoring, then anomaly detection capability is improved, but data quantity requirements increase significantly

Engineering Contradiction:
Improveanomaly detection capabilityVSAvoiddata quantity
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies preliminary action by pre-processing vibration data through signal processing techniques (FFT, wavelet transform, envelope analysis) to extract meaningful features before feeding them to the deep learning model. This preprocessing step transforms raw vibration signals into characteristic features that capture machine health information, allowing the model to learn from fewer, more informative data samples rather than requiring large quantities of raw data.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent extracts key features from vibration signals using signal processing methods (frequency spectrum, time-frequency analysis, statistical parameters). By taking out and isolating the most discriminative features from the raw vibration data, the system reduces the dimensionality and information redundancy, enabling effective anomaly detection with smaller data sets that contain only the essential diagnostic information.

Inventive Principle:
Principle #2Taking out (Extraction)

2Device complexity

If traditional rule-based monitoring systems are used, then setup complexity is reduced, but rule coverage and adaptability to various machine types are limited

Engineering Contradiction:
Improvesetup complexityVSAvoidrule coverage
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements self-service by employing deep learning models that automatically learn diagnostic rules and patterns from vibration data without requiring manual rule configuration. The system autonomously adapts to different machine types and failure modes by training on labeled data, eliminating the need for experts to manually create and maintain complex rule sets for each machine configuration, thereby achieving both simplicity and broad adaptability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent achieves universality by developing a deep learning framework that can be applied across diverse machine types and monitoring scenarios. The same core architecture processes vibration data from different equipment, adapting to various failure modes (imbalance, misalignment, bearing defects, gear faults) through learned features rather than machine-specific rules, enabling a single system to serve multiple functions and machine types.

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

3Measurement precision

If more vibration analysis techniques are applied, then early detection accuracy is improved, but system complexity increases

Engineering Contradiction:
Improveearly detection accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges multiple vibration analysis techniques (FFT, wavelet transform, envelope analysis, statistical parameter extraction) into a unified deep learning pipeline. Instead of implementing separate analysis systems for each technique, the patent integrates them as sequential or parallel processing stages within a single neural network architecture, achieving comprehensive feature extraction while managing complexity through unified model training and centralized control.

Inventive Principle:
Principle #5Merging (Combining)
