Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are placed to directly measure valve torque, then measurement precision is improved, but device complexity and difficulty of implementation worsen due to physical constraints of valve stem engagement
Solution Approach 1:
The adaptor serves as an intermediary component between the actuator and valve stem. It includes a sensor interface that couples to the valve stem and an electronics module contained within the adaptor body, enabling torque measurement without direct modification to the valve stem or actuator. The adaptor transmits mechanical force while providing electrical connections for power and data.
Solution Approach 2:
The system is divided into separate functional modules: the adaptor housing, the sensor interface, the electronics module, and the actuator. This segmentation allows the sensors and electronics to be positioned in the adaptor rather than directly on the valve stem, simplifying installation and maintenance while maintaining measurement accuracy.
2Reliability
If direct measurement of valve torque is implemented, then reliability of performance monitoring is improved, but ease of operation worsens due to challenges in sensor placement and power provision
Solution Approach 1:
The adaptor acts as a mediator that simplifies installation by providing a standardized interface between the actuator and valve stem. The electronics module is contained within the adaptor, eliminating the need for separate sensor mounting and wiring operations, thereby improving ease of operation while maintaining reliable monitoring.
3Productivity
If data processing capabilities are integrated into the valve system, then productivity of predictive analysis is improved, but device complexity worsens due to additional electronics and power requirements
Solution Approach 1:
The electronics module integrating data processing capabilities is merged with the adaptor structure. This combination allows the system to perform predictive analysis locally without requiring separate external processing equipment, improving productivity while containing complexity within a single integrated component.
