A field device with a transmission device that integrates electrical and mechanical coupling of function modules, including engine control modules, using a single transmission system for both control signals and drive energy, allowing for a compact and scalable structure that can supply drive energy to multiple engine control modules and function modules, eliminating the need for separate bus systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate signal and energy bus systems are used, then control signals and power can be transmitted independently, but the arrangement of electrical lines becomes complex and non-compact
Solution Approach 1:
The patent combines separate signal and energy bus systems into a single integrated transmission device. The transmission device includes both signal transmission lines and power supply lines that work together to provide both control signals and electrical energy through the same physical interface, eliminating the need for separate bus systems and reducing overall system complexity.
Solution Approach 2:
The transmission device is designed with multi-functionality, serving both as a signal transmission medium and an energy supply conduit. The same transmission interface handles both control signals from the control unit and electrical energy for the actuators, making the system more compact while maintaining independent transmission capabilities through functional separation within the integrated structure.
2Device complexity
If a single transmission device is used for both control signals and drive energy, then the structure becomes compact, but the power capacity must be increased to handle multiple engine control modules
Solution Approach 1:
The transmission device is segmented into multiple transmission modules, each capable of handling a portion of the total power load. Each module includes its own power supply lines and signal transmission lines, allowing the system to scale power capacity by adding or removing modules as needed, rather than requiring a single high-capacity transmission device.
Solution Approach 2:
The system dynamically allocates power capacity across multiple transmission modules based on the actual power requirements of connected engine control modules. The power supply can be adjusted and scaled to match the load, allowing the integrated structure to maintain compactness while providing sufficient power capacity through modular scalability.
3Power
If multiple transmission modules are used, then power capacity can be scaled, but the number of electrical connections increases
Solution Approach 1:
The system is divided into standardized transmission modules with uniform interfaces. Each module contains complete signal and power transmission capabilities, allowing them to be connected in series or parallel configurations. The segmentation creates repeatable units that reduce the complexity of adding connections, as each module presents the same interface requirements.
Solution Approach 2:
The transmission modules use universal, standardized interfaces that can connect to any adjacent module or to engine control modules. This universality means that the same connection type is used throughout the system, reducing the variety of connection types that must be managed and simplifying the overall electrical connection architecture despite the increased number of connections.
