Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If wind turbines operate continuously to maximize power generation, then productivity increases, but reliability deteriorates due to wear and aging components

Engineering Contradiction:
Improvepower generationVSAvoidcomponent condition
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary maintenance actions by predicting component failures before they occur. Sensors monitor vibration, temperature, and other parameters continuously, and the predictive maintenance system schedules maintenance activities in advance based on predicted component degradation, preventing failures before they affect productivity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements continuous feedback loops where sensors monitor turbine operation in real-time, data is analyzed to predict component degradation, and maintenance decisions are adjusted based on this feedback. This closed-loop system optimizes the balance between continuous operation and maintenance timing.

Inventive Principle:
Principle #23Feedback

2Reliability

If predictive maintenance is implemented to improve reliability, then device complexity increases due to additional sensors and data processing systems

Engineering Contradiction:
Improvecomponent conditionVSAvoidmonitoring system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The monitoring system is designed with multi-functionality, where the same sensors and data processing infrastructure serve both operational monitoring and predictive maintenance functions. This universal system reduces overall complexity compared to having separate dedicated systems for each function.

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

Solution Approach 2:

The system enables self-service through automated data collection, analysis, and maintenance scheduling. The predictive maintenance platform automatically processes sensor data, predicts failures, and generates maintenance recommendations without requiring extensive manual intervention, reducing operational complexity.

Inventive Principle:
Principle #25Self-service

3Reliability

If maintenance is performed frequently to maintain high reliability, then loss of time increases due to shutdowns, but productivity decreases

Engineering Contradiction:
Improvecomponent conditionVSAvoiddowntime
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary maintenance actions by predicting component failures before they occur. Sensors monitor vibration, temperature, and other parameters continuously, and the predictive maintenance system schedules maintenance activities in advance based on predicted component degradation, preventing failures before they affect productivity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The maintenance schedule is dynamic rather than static. The system continuously adjusts maintenance timing based on real-time component condition monitoring and failure predictions, optimizing maintenance intervals to minimize downtime while maintaining reliability. This dynamic approach replaces fixed scheduled maintenance with condition-based maintenance.

Inventive Principle:
Principle #15Dynamics

AI summary

In some examples, a system receives first sensor data from respective wind turbines of a plurality of wind turbines. For instance, the first sensor data may include at least a power output and a wind speed per time interval. The system trains at least one respective model for each respective wind turbine based on the first sensor data received from that respective wind turbine. Further, the system receives, for a second time period, respective second sensor data from the respective wind turbines. The system executes, using the respective second sensor data, the respective model trained using the first sensor data received from that respective wind turbine to determine, for each respective wind turbine, a predicted power output for an upcoming period. The predicted power outputs may be aggregated to determine a total predicted power output and at least one action is performed based on the total predicted power output.
