Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate simulation assemblies are used to simulate decentralized peripheral behavior, then simulation capability is provided, but hardware configuration must be adjusted and device complexity increases
Solution Approach 1:
The patent merges the simulation functionality directly into the decentralized peripheral's interface module by implementing a simulation mode that can be activated via a software setting. This eliminates the need for separate simulation assemblies and reduces hardware configuration complexity, as the same physical device serves both real operation and simulation purposes.
Solution Approach 2:
The decentralized peripheral is designed to perform multiple functions: it can operate in real operation mode with field devices and in simulation mode generating simulated process input values. This multi-functionality is achieved through a programmable element that can be configured via software, allowing the device to adapt its behavior based on the selected mode without requiring hardware changes.
2Reliability
If separate simulation assemblies are used for testing, then simulation functions are provided, but the number of components and hardware adjustments increases
Solution Approach 1:
The simulation functions are merged into the existing decentralized peripheral structure. The interface module contains a programmable element that can execute simulation routines, eliminating the need for separate simulation assemblies and reducing the total number of components in the system.
Solution Approach 2:
The simulation mode creates a virtual copy of the decentralized peripheral's behavior through software. Instead of using physical simulation assemblies that replicate hardware, the system uses a software-based simulation that generates realistic process input values, reducing component count while maintaining testing reliability.
3Adaptability or versatility
If hardware configuration is adjusted for simulation, then simulation can be performed, but switching between real and simulation modes becomes complex
Solution Approach 1:
The system implements dynamic mode switching through software configuration rather than fixed hardware settings. The programmable element in the interface module can be reconfigured via downloadable software settings to switch between real operation mode and simulation mode, allowing flexible and easy transitions without physical hardware adjustments.
Solution Approach 2:
The transition between real and simulation modes is achieved by changing software parameters and settings rather than hardware configuration. The programmable element responds to different operational parameters defined in software, enabling easy mode switching through parameter adjustment instead of physical reconfiguration.
