Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a contactor system is designed without switching state detection, then the device complexity is reduced, but the ability to detect and monitor the switching state is lost
Solution Approach 1:
The contactor system is divided into two functional parts: the existing contactor and a separate detectable module. The movable element of the contactor transmits movement to the contactor module, which contains the deflection lever and sensor components. This segmentation allows switching state detection without redesigning the entire contactor system.
Solution Approach 2:
A deflection lever is introduced as an intermediary mechanical element between the contactor's movable element and the sensor. The deflection lever converts the linear movement of the movable element into a detectable displacement that the sensor can measure, enabling indirect detection of the switching state.
2Loss of information
If a deflection lever mechanism is added to indicate switching state, then the switching state indication capability is improved, but the device complexity increases
Solution Approach 1:
The movable element serves dual functions: it acts as both the switching element of the contactor and as a movement transmitter to the contactor module. This multi-functionality reduces the need for additional separate components and simplifies the overall structure.
Solution Approach 2:
The contactor module uses the existing mechanical movement of the contactor's movable element to drive its own detection mechanism. The system is self-actuating, requiring no external power or additional actuators, as the switching action itself provides the movement needed for detection.
