Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing process control devices for pneumatic actuating drives are not cost-effectively configurable for different applications due to complex assembly requirements and limited adaptability of control valve devices.
Innovation Solution
A process control device with an electropneumatic control unit featuring a separate interface plate that acts as both a fastening base and a pneumatic interface, allowing for the mounting of a control valve device and enabling fluid and mechanical adaptation to a uniform fastening module, which includes a support plate for fluid channels and feedback components, facilitating simpler and more versatile assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the control valve device is directly mounted on the fastening module, then the assembly structure is simple, but the adaptability to different applications is limited and assembly complexity increases for different configurations
Solution Approach 1:
The device is segmented into distinct functional modules: a standardized fastening module and a separate control valve device that can be independently configured and mounted. This segmentation allows each module to be optimized separately and assembled in different configurations for different applications, reducing overall assembly complexity while improving adaptability.
Solution Approach 2:
The fastening module is designed with universal mounting interfaces and standardized fluid connections that can accommodate different control valve devices. This universal design allows the same fastening module to be used across multiple applications and configurations, enhancing adaptability without increasing assembly complexity.
2Adaptability or versatility
If the control valve device is directly mounted on the fastening module, then the number of components is reduced, but the fluid connection adaptability and mechanical adaptation flexibility are limited
Solution Approach 1:
The mounting flange with integrated fluid connections acts as an intermediary component between the fastening module and the control valve device. This intermediary provides standardized interfaces that facilitate both fluid connections and mechanical mounting, enabling flexible adaptation to different applications while maintaining cost-effective production through standardized component design.
3Adaptability or versatility
If a separate interface plate is introduced between the fastening module and control valve device, then the assembly versatility and fluid adaptation capability are improved, but the device complexity increases
Solution Approach 1:
The mounting flange combines multiple functions into a single integrated component: it serves as both the mechanical mounting interface and the fluid connection interface. By merging these functions, the design achieves configuration flexibility and adaptability without significantly increasing the number of separate components, thus avoiding excessive device complexity.

AI summary
A process control device has an electropneumatic control unit which is used for activating a pneumatic actuating drive. The control unit has a fastening module by means of which it is fastened to a drive housing of the actuating drive. The control unit includes an interface plate which is separate from the fastening module, is mounted on a top side of the fastening module and is fluidically connected, through the fastening module, to the actuating drive. The control unit includes an electrically actuatable control valve device which is fixed to the fastening module by being mounted on the interface plate fixed to the fastening module. In this way, a process control device can be produced in an easily and variably configurable manner.
