Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wired sensors and continuous monitoring are used, then measurement precision and reliability are improved, but device complexity and installation cost increase
Solution Approach 1:
The patent replaces wired mechanical sensor systems with wireless monitoring technology. The wireless sensor node includes vibration sensors, microcontrollers, and wireless transmitters that eliminate complex wiring infrastructure while maintaining continuous monitoring capabilities. This substitution reduces installation complexity and device complexity while preserving measurement precision for vibration-based fault detection.
Solution Approach 2:
The monitoring system is divided into distributed wireless sensor nodes that can be independently deployed. Each node contains its own processing and transmission capabilities, allowing the system to be segmented into modular units that reduce overall system complexity while maintaining comprehensive monitoring coverage across multiple monitoring points.
2Reliability
If route-based inspections are performed frequently, then reliability and fault detection capability are improved, but loss of time and operational disruption increase
Solution Approach 1:
The system implements continuous monitoring of vibration parameters without requiring periodic shutdowns or interruptions to machine operation. Sensors continuously capture vibration data during normal operation, enabling fault detection without loss of production time while maintaining high reliability through constant surveillance of equipment health.
Solution Approach 2:
The monitoring system operates autonomously during machine operation, with sensors self-powered and data automatically transmitted and analyzed. This eliminates the need for manual inspection interventions that would require operational disruption, allowing the system to provide continuous reliability monitoring without time loss to inspection activities.
3Ease of operation
If traditional maintenance scheduling is used, then ease of operation is maintained, but unexpected failures and loss of time increase
Solution Approach 1:
The system provides real-time feedback on equipment health status through continuous vibration monitoring and automated analysis. This feedback mechanism enables dynamic adjustment of maintenance scheduling based on actual equipment conditions rather than fixed schedules, reducing unexpected failures and unplanned downtime while maintaining operational simplicity through automated alerts and recommendations.
