Solution Overview

Problem

Existing fieldbus technologies lack the capability for remote and wireless configuration, monitoring, and control of fieldbus controllers and connected instruments, requiring physical access for configuration and control functions.

Innovation Solution

A method and apparatus enabling remote and wireless operation of fieldbus controllers through a user interface accessible on portable devices, allowing configuration, monitoring, and control of I/O modules connected to valve assemblies, including configuration interfaces for setting operating modes, monitor interfaces for reading status information, and control interfaces for controlling the state of I/O modules, utilizing wireless communication protocols like Bluetooth, Ethernet, or USB.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a remote display device is used for the user interface, then an operator can view diagnostic and service information remotely, but the device cannot transmit configuration data wirelessly or facilitate configuration or control functions

Engineering Contradiction:
Improveremote monitoring capabilityVSAvoidconfiguration and control functionality
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The fieldbus controller is equipped with a wireless communication interface that enables it to perform multiple functions including configuration, monitoring, and control operations through a single wireless connection to a portable device, eliminating the need for separate devices for different functions

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

Solution Approach 2:

A portable device (such as a smartphone or tablet) serves as an intermediary between the operator and the fieldbus controller, providing a wireless interface that supports configuration, monitoring, and control functions through downloaded applications or webpages

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If an operator accesses the user interface physically connected to the fieldbus controller, then configuration and control functions can be performed, but the operator must have physical access to the controller which may be hard-to-reach

Engineering Contradiction:
Improveconfiguration and control functionalityVSAvoidphysical accessibility
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The physical mechanical connection (wired interface) is replaced with a wireless communication system, allowing operators to perform configuration and control functions remotely without physical contact with the fieldbus controller through Bluetooth, Wi-Fi, or other wireless protocols

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If a conventional wired user interface is used on the fieldbus controller, then configuration and monitoring can be performed, but the system requires physical connection and cannot support remote wireless operation

Engineering Contradiction:
Improvestable connectionVSAvoidremote accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system transitions from a static wired connection to a dynamic wireless connection that can adapt to different operational scenarios, allowing the interface to be physically present on the controller while also being remotely accessible through wireless communication channels

Inventive Principle:
Principle #15Dynamics
