Solution Overview

Problem

Commissioning field devices in automation technology, particularly level measuring devices, requires technical expertise due to the need for parameterization and identification of complex parameters through text-based entry, which can be cumbersome and unintuitive for operators without technical experience.

Innovation Solution

A method using an operating unit with a display and camera to visualize parameters as virtual symbols overlaid on the field of view, allowing operators to easily identify and set parameters through intuitive gestures or input, with automatic retrieval from databases and transmission to the field device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If text-based parameter entry is used for field device commissioning, then parameterization can be completed, but the ease of operation deteriorates due to technical expertise requirements and cumbersome input processes

Engineering Contradiction:
Improveease of parameter settingVSAvoidcomplexity of commissioning process
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical/text-based parameter entry process with an optical/gesture-based system. The camera captures visual information from the field device, and gesture recognition substitutes for manual text input, transforming the commissioning process from text-based to vision-based interaction.

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

Solution Approach 2:

The patent creates a visual copy of the field device parameters through camera imaging. Instead of requiring operators to read and enter parameter names textually, the system captures images of the device display or labels and uses optical character recognition to extract parameter values directly from the visual copy.

Inventive Principle:
Principle #26Copying

2Productivity

If traditional commissioning methods are used, then field devices can be parameterized, but the time required for commissioning increases due to manual parameter identification and entry

Engineering Contradiction:
Improvecommissioning speedVSAvoidtime for parameter setting
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by automatically capturing images of the field device and pre-processing the visual data before the operator needs to set parameters. The camera continuously monitors the device display, and parameters are pre-identified through image recognition, so that when the operator needs to set a parameter, it is already ready for quick selection.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The field device itself serves as the source of parameter information through its display or labels. The camera captures information directly from the device, eliminating the need for separate documentation or manual lookup tables. The system extracts parameter names and values directly from the device's own visual output.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If manual parameter identification is required, then accurate parameterization can be achieved, but the difficulty of detecting and measuring parameters increases for operators without technical experience

Engineering Contradiction:
Improveaccuracy of parameter identificationVSAvoiddifficulty of parameter recognition
Core Design Contradiction:
Measurement precisionVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces an intermediary system consisting of the camera and image recognition software that mediates between the field device parameters and the operator. Instead of requiring the operator to directly interpret technical parameters, the intermediary automatically captures, processes, and presents parameter information in a more accessible visual format.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system uses visual differentiation through color or highlight changes to indicate different parameter states. Parameters that need to be set are highlighted or color-coded in the captured images, making them easily distinguishable from other device elements. This visual emphasis guides the operator's attention to the correct parameters without requiring deep technical knowledge.

Inventive Principle:
Principle #32Color changes
