Solution Overview
Problem
Existing valve islands lack flexibility in accommodating modules with different voltage requirements and data communication needs, often requiring external sources for additional voltages and separate data lines.
Innovation Solution
Incorporating an adapter module with a circuit unit that extends a continuous data line and voltage supply line within the valve island, allowing for internal data and voltage distribution to various modules, including voltage conversion and electromagnetic protection, enabling modular assembly and operation without external sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a common central supply unit is used for all valves in the valve island, then the structure is simplified and manufacturing is easier, but modules with different voltage requirements cannot be accommodated
Solution Approach 1:
The valve island is divided into multiple independently addressable modules (valve modules and adapter modules), each with its own power supply connection. This segmentation allows different modules to receive different voltages through the data lines, enabling accommodation of modules with different voltage requirements while maintaining a unified modular structure.
Solution Approach 2:
The data lines serve dual functions: they transmit data signals for communication and control, and simultaneously function as power supply lines by providing different voltages to different modules. This multi-functionality eliminates the need for separate power supply connections for each module type, maintaining structural simplicity while enabling voltage diversity.
2Adaptability or versatility
If separate external voltage sources are provided for each module type, then different voltage requirements are met, but the device complexity and number of external interfaces increase
Solution Approach 1:
The power supply function is merged with the existing data communication infrastructure. The same data lines that carry control signals are also used to supply power to different modules. This merging eliminates the need for separate external voltage sources and reduces the number of external interfaces while maintaining the ability to provide different voltages to different modules.
Solution Approach 2:
Each module is designed to receive its required voltage through the data lines from the central control unit. The modules self-configure their power requirements through the data communication protocol, eliminating the need for manual external power connections and reducing system complexity.
3Adaptability or versatility
If separate data lines are used for each module type, then data communication requirements are met, but the device complexity and wiring requirements increase
Solution Approach 1:
The data lines are designed to serve multiple functions simultaneously: bidirectional data communication, module addressing, control signal transmission, and power supply delivery. This universal design allows a single wiring infrastructure to support diverse communication and power needs of different module types without increasing wiring complexity.
4Adaptability or versatility
If multiple external sources are required for voltage and data, then module-specific requirements are met, but the ease of operation and installation is reduced
Solution Approach 1:
The system automatically configures power distribution and data communication through the modular architecture. When modules are installed in the valve island, they are automatically addressed and configured through the data lines without requiring manual external connections. This self-configuration greatly simplifies installation and operation while maintaining support for diverse module types.

AI summary
A valve island has at least one valve module and an adapter module, wherein the adapter module includes a first data line and a first voltage supply line, which each extend continuously from an interface on a first front side forming an outer side of the adapter module to an interface on a second side of the adapter module pointing into the valve island. In the adapter module a circuit unit is provided, which within the adapter module is connected to the first data line and/or the first voltage supply line and from which within the adapter module an internal data line and/or an internal voltage supply line proceeds or proceed, which each extends or extend to an interface on the second side of the adapter module.
