Engineering Contradiction Analysis
1Reliability
If a sensor unit with integrated control system is used to monitor piston movement, then system reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines the sensor element, control unit, and pump control functions into a single integrated sensor unit. The control unit is embedded within the sensor housing, merging monitoring and control functions into one component. This integration improves reliability by ensuring coordinated operation while managing complexity through unified design rather than separate components.
Solution Approach 2:
The sensor unit is designed with universal applicability to different pump types and lubrication systems. The control unit can be configured through programmable parameters to work with various metering devices, making the sensor unit multi-functional. This universality allows the same basic design to serve multiple purposes across different applications, improving reliability through proven design while avoiding the complexity of multiple specialized components.
2Reliability
If monitoring of piston movement is implemented, then fault detection capability is improved, but system complexity increases
Solution Approach 1:
The sensor element provides continuous feedback on piston movement to the control unit. The sensor detects the position and movement of the metering piston and feeds this information back to the control unit, which monitors the feedback signals to detect faults. This feedback mechanism improves fault detection capability by providing real-time information on system operation while adding minimal complexity through straightforward sensor-to-controller signaling.
Solution Approach 2:
The system performs self-monitoring and self-diagnosis through the integrated sensor and control unit. The control unit automatically evaluates sensor signals and detects faults without requiring external monitoring systems. The system serves itself by having the sensor unit continuously check piston movement and report abnormalities, improving fault detection while avoiding the complexity of separate external monitoring equipment.
