Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual analysis methods are used for maintenance prediction, then system complexity is reduced, but measurement precision and detection accuracy deteriorate

Engineering Contradiction:
Improvemaintenance event detection accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments maintenance prediction into distinct functional modules: data collection module that gathers sensor data from multiple resources, data processing module that applies dynamic time warping algorithms, pattern recognition module that identifies precursor signals, and prediction module that forecasts maintenance events. This segmentation enables high detection accuracy through specialized processing while managing system complexity through modular architecture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary computational layer that processes raw sensor data through dynamic time warping algorithms and statistical analysis before presenting processed insights to users. This intermediary layer handles the complex data transformation and pattern recognition tasks, isolating the complexity from end users while maintaining high detection accuracy through sophisticated intermediate processing steps.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If real-time data integration from multiple sources is implemented, then measurement precision improves, but device complexity increases

Engineering Contradiction:
Improvemaintenance prediction accuracyVSAvoiddata integration complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system implements a universal data processing framework that handles multiple data sources (sensor logs, maintenance records, operational data) through a single integrated architecture. The dynamic time warping algorithm serves as a multi-functional tool that can compare and synchronize various types of time-series data from different resources, enabling high prediction accuracy without requiring separate processing systems for each data type.

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

Solution Approach 2:

The system merges data collection, processing, analysis, and prediction functions into an integrated maintenance prediction system. By combining historical maintenance data with real-time sensor data from multiple resources and applying unified analytical methods, the system achieves comprehensive monitoring accuracy while reducing the complexity that would arise from separate discrete systems.

Inventive Principle:

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system applies dynamic time warping selectively to critical comparison tasks rather than continuously processing all data streams. By focusing computational resources on comparing sensor logs only when maintenance events are detected or during scheduled analysis periods, the system achieves high measurement precision for critical predictions while reducing overall computational energy consumption through partial application of the intensive algorithm.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system performs preliminary data preprocessing and filtering before applying dynamic time warping, organizing sensor logs and maintenance records into standardized formats in advance. This preliminary action reduces the computational burden during actual time warping operations by pre-processing data to extract only relevant features, thereby maintaining high comparison accuracy while reducing real-time computational energy requirements.

Inventive Principle:

Core Design Contradiction:

Solution Approach 1:

The system performs preliminary analysis of historic maintenance data during off-peak periods to establish baseline patterns and precursor signal signatures for different failure modes. By pre-processing historical data to create reference patterns and statistical models in advance, the system can quickly compare real-time sensor data against these pre-established patterns, thereby maintaining high prediction reliability through comprehensive historical analysis while reducing real-time data processing time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements accelerated processing methods that skip less critical analysis steps during real-time operation, focusing computational effort only on identifying precursor signals that match pre-established high-risk patterns. By rushing through the analysis of only the most critical data points that indicate potential failures, the system maintains high prediction reliability for critical events while minimizing overall data analysis time through selective processing.

Inventive Principle:
Principle #21Skipping (Rushing through)

AI summary

Systems, methods, and non-transitory computer-readable media can be configured to perform receiving a notification of a maintenance event associated with a resource. The method includes retrieving historic maintenance data in relation to the resource with which the fault is associated, the maintenance information originating from a time period preceding the time of the maintenance event. The method includes identifying at least a portion of the retrieved historic maintenance data as being indicative of the maintenance event. The method also includes causing the portion of the retrieved historic maintenance data identified as being indicative of the maintenance event to be stored as a precursor signal of the maintenance event. The method also includes causing future maintenance data received from a plurality of resources related to the resource with which the maintenance event is associated to be monitored to predict a future occurrence of the maintenance event in the plurality of resources.
