Solution Overview

Problem

Identifying the root cause of maintenance issues in motor drive systems is difficult and time-consuming due to limited visualization capabilities, making routine diagnostics inefficient.

Innovation Solution

Implementing a barcode system on motor drive systems that can be static or dynamic, allowing users to access information and troubleshooting guidance using a barcode reader, such as a phone, to facilitate efficient diagnostics by encoding nameplate information or operational issue resolutions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If traditional motor drive systems with limited visualization capabilities are used, then device complexity is reduced, but diagnostic efficiency and information accessibility deteriorate

Engineering Contradiction:
Improvediagnostic timeVSAvoidsystem complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

A barcode is introduced as an intermediary element that bridges the motor drive system and external diagnostic resources. The barcode encodes information such as motor parameters, serial numbers, or diagnostic URLs, which can be quickly scanned and decoded by external devices to access detailed diagnostic data, manuals, or support resources without adding complexity to the motor drive system itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The solution transitions from a two-dimensional display limitation on the motor drive interface to a multi-dimensional information access model. By encoding data in a barcode and linking to external resources (websites, databases, mobile applications), the system accesses information in additional dimensions (online resources, mobile devices) rather than being constrained to the limited display of the motor drive interface.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of information

If detailed diagnostic information is provided directly on motor drive displays, then information accessibility improves, but display area requirements and device complexity increase

Engineering Contradiction:
Improveinformation accessibilityVSAvoiddisplay area
Core Design Contradiction:
Loss of informationVSArea of stationary object

Solution Approach 1:

Detailed diagnostic information is extracted from the motor drive system and placed in external resources such as online databases, manuals, or support systems. The barcode on the motor drive contains only essential identifying information or URLs, while the comprehensive diagnostic data resides externally, eliminating the need for large display areas on the motor drive interface.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of displaying all diagnostic information directly on the motor drive, the system uses barcodes that reference or link to copies of the information stored in external databases or online resources. Users can access complete diagnostic data through these references without requiring the physical display space to present all information locally.

Inventive Principle:
Principle #26Copying

3Ease of operation

If comprehensive diagnostic resources are made accessible, then troubleshooting effectiveness improves, but system complexity and implementation cost increase

Engineering Contradiction:
Improvetroubleshooting easeVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system enables operators to perform self-service diagnostics by scanning the barcode and accessing troubleshooting information, manuals, or diagnostic tools through mobile devices or computers. This self-service capability allows comprehensive diagnostic resources to be available without requiring complex integrated diagnostic systems within the motor drive itself, as users independently access the needed information and perform troubleshooting steps.

Inventive Principle:
Principle #25Self-service

AI summary

An industrial automation system includes automation components, such as a motor drive, configured to provide signals to perform automation operations, such as driving an electric motor. A barcode is disposed on an industrial automation component is configured to be scanned by a user device to provide the user device with information relating to the automation component or operation of the automation component. The barcode may be dynamically generated by the automation component and may utilize various mechanism for permitting access to the information.
