Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If component monitoring systems are implemented to enable predictive maintenance, then reliability and availability improve, but device complexity and initial cost increase
Solution Approach 1:
The monitoring system is divided into separate functional modules: vibration sensor assemblies for data collection, comparison assemblies for analysis, and communication assemblies for data transmission. This modular segmentation allows the system to be implemented incrementally and reduces overall complexity by assigning specific functions to discrete components.
Solution Approach 2:
The comparison assemblies are designed to be portable and retrofittable across different circuit breaker models, serving multiple functions including vibration analysis, temperature monitoring, and predictive maintenance across various electrical equipment. This multi-functionality reduces the need for separate monitoring systems for different components.
2Measurement precision
If continuous monitoring of all circuit breaker components is implemented, then measurement precision and failure prediction improve, but loss of time for installation and complexity increase
Solution Approach 1:
Nominal data representing healthy component characteristics is collected and stored in databases before deployment. This preliminary action allows the system to immediately compare actual measurements against established baselines without requiring extensive on-site calibration or setup time, enabling rapid deployment while maintaining measurement precision.
Solution Approach 2:
The system uses portable comparison assemblies that can be copied and deployed across multiple circuit breakers. These portable units contain the necessary processing capability and nominal data, allowing rapid deployment without requiring permanent installation or complex wiring modifications at each location.
3Ease of operation
If modular portable monitoring systems are used instead of permanent installations, then ease of operation and retrofittability improve, but measurement precision and reliability may be compromised
Solution Approach 1:
The portable comparison assemblies are designed to adapt to different circuit breaker models by adjusting measurement parameters and thresholds based on the specific equipment being monitored. This parameter adaptation ensures measurement consistency across diverse equipment while maintaining portability and ease of deployment.
