Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvevalve torque measurementVSAvoidsensor placement and power supply
Core Design Contradiction:
Measurement precisionVSDevice complexity

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improvevalve performance monitoringVSAvoidsensor installation and maintenance
Core Design Contradiction:

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:
