Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blocking system is integrated into the joystick structure, then the blocking function is achieved, but the structure becomes more complex
Solution Approach 1:
The control apparatus is divided into separate functional modules: the actuating section with control rods, the sensor section for detection, and the auxiliary section with blocking devices. These modules can be connected or disconnected independently, allowing the blocking function to be added or removed without redesigning the entire joystick structure.
Solution Approach 2:
The connecting interfaces are designed to be universal, allowing the same actuating section to work with or without the auxiliary blocking section. The standardized interfaces enable a single base design to serve multiple application needs, from simple control to control with blocking functionality.
2Adaptability or versatility
If blocking devices are added to provide maintaining function, then the control capability is improved, but the device complexity increases
Solution Approach 1:
The system transitions from a static integrated design to a dynamic configurable architecture where the auxiliary section can be connected or disconnected based on application requirements. This dynamic modularity allows the device to adapt its complexity level to match the needed control capability.
Solution Approach 2:
The connecting interfaces act as intermediaries that enable or disable the blocking function without requiring structural modifications to the core actuating or sensor sections. These interfaces mediate between the simple and complex configurations, allowing smooth transitions between different operational modes.
3Adaptability or versatility
If modular sections with connecting interfaces are used, then the adaptability to different applications is improved, but the assembly complexity increases
Solution Approach 1:
The control apparatus is segmented into standardized modules with uniform connecting interfaces. This segmentation allows each module to be manufactured independently using optimized processes, and the standardized interfaces simplify the assembly process by reducing the variety of connection types that workers must handle.

AI summary
A modular control apparatus for actuating hydraulic valve systems includes an actuating section including a tilting control member and a plurality of control rods provided with a pusher, which interacts with the control member so as to translate the control rods in the longitudinal direction, a sensor section including a plurality of sensor members suitable to detect a movement in the longitudinal direction of said control rods and a blocking section comprising a blocking device that is capable of individually blocking in the longitudinal direction each of said control rods. The actuating section can be alternately connected to the blocking section or to the sensor section so that the sensor section can be directly connected to the actuating section, detecting the longitudinal movement of the control rods also if the blocking section is not present.
