Innovation Solution

A portable communicator with an intuitive user interface, capable of wireless communication via Bluetooth, that allows for efficient configuration and analysis of field devices, using preprogrammed settings and a limited set of procedures, reducing the need for navigating complex menus and configuration screens, and includes a software system compatible with various hardware platforms for interacting with field devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional handheld field maintenance tools are used, then field devices can be accessed and analyzed, but the tools are complex and require coordination between operators and maintenance personnel, reducing ease of operation

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system is segmented into distinct functional modules: a portable communicator for user interaction, a wireless communication unit for data transmission, and a process control system for execution. This segmentation allows each component to be optimized independently, simplifying the user interface while maintaining comprehensive functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The portable communicator acts as an intermediary device between the user and the complex process control system. It provides a simplified interface that translates user commands into system operations, eliminating the need for users to navigate complex menus and configuration screens directly.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Difficulty of detecting and measuring

If comprehensive field device analysis capabilities are provided, then performance detection is improved, but the interface becomes complex with numerous menus and configuration screens, increasing device complexity

Engineering Contradiction:
Improvedifficulty of detecting and measuringVSAvoiddevice complexity
Core Design Contradiction:
Difficulty of detecting and measuringVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by automatically connecting to the process control system and pre-configuring analysis parameters before the user initiates field device analysis. This eliminates the need for users to manually navigate through multiple configuration screens and menus.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The portable communicator automatically manages connection establishment, parameter configuration, and analysis execution based on user input. The system performs self-service functions by handling complex setup procedures autonomously, requiring minimal user intervention beyond simple command selection.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If wireless communication is implemented for portable access, then accessibility to field devices is improved, but coordination between operators and maintenance personnel is required, increasing operational complexity

Engineering Contradiction:
ImproveaccessibilityVSAvoidcoordination time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The portable communicator is designed as a universal device that can be used by both operators and maintenance personnel for multiple functions including field device analysis, configuration, and monitoring. This multi-functionality eliminates the need for role-specific tools and reduces coordination requirements.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A portable communicator for operating a field device. The portable communicator is configured to communicate with the field device to configure and/or analyze performance of a field device in an efficient manner. In some embodiments, the portable communicator includes an intuitive user interface that allows the user to perform a relatively limited set of preconfigured procedures on a field device. The portable communicator may communicate with the field device via a wire and/or wirelessly. In one embodiment, the portable communicator is a Bluetooth-enabled smartphone, a PDA, a pocket PC, or any Bluetooth- enabled generic mobile communication device. The portable communicator may communicate with the field device via a wireless communication unit (e.g., Bluetooth modem) coupled to the field device. In a process plant environment, in which the field device is coupled to a controller, the portable communicator may communicate with the field device without communicating with the controller.
