Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for obtaining operating parameters of electrical substation components, such as intelligent electronic devices, are time-consuming and prone to human error, especially when dealing with multiple components in the same vicinity, requiring manual selection and validation through complex software navigation.
Innovation Solution
An electronic module, such as a smartphone with a camera, reads machine-readable codes like QR codes displayed on a human-machine interface, automatically retrieving and validating operating parameters, including identification, network connection, and configuration settings, thereby streamlining the process and reducing manual effort.

Engineering Contradiction Analysis
1Reliability
If manual methods are used to obtain operating parameters of electrical substation components, then the process allows human verification and control, but the process becomes time-consuming and prone to human error
Solution Approach 1:
The patent replaces manual mechanical operations (physically navigating software menus, manually entering parameters) with an automated optical system. The electronic module uses a camera to capture machine-readable codes and automatically extracts operating parameters, eliminating manual intervention while ensuring accuracy through systematic automated validation processes.
Solution Approach 2:
The electrical substation component performs self-identification by displaying machine-readable codes containing its operating parameters. The component essentially serves itself by providing the information automatically when scanned, eliminating the need for manual querying and parameter entry by operators.
2Ease of operation
If manual navigation through control software is used to retrieve parameters, then the process allows flexible verification, but the complexity of software navigation increases the difficulty of operation
Solution Approach 1:
The patent extracts the essential identification information (operating parameters) from the complex control software environment and encodes it in a machine-readable code displayed on the component. This extracts the critical information needed for operation away from the complex software navigation interface, making it accessible through simple optical scanning.
Solution Approach 2:
The machine-readable code acts as an intermediary between the complex control software system and the user. Instead of requiring direct interaction with complex software menus, the code provides a simplified interface that can be read by electronic modules, bridging the gap between system complexity and user simplicity.
3Productivity
If multiple electrical substation components are managed manually, then each component can be individually verified, but the overall productivity decreases due to repetitive manual tasks
Solution Approach 1:
The electronic module is designed with universal functionality to manage multiple different electrical substation components. It can scan, decode, validate, and extract parameters from various component types using the same machine-readable code system, enabling efficient batch processing while maintaining consistent validation standards across all components.
