Solution Overview
Problem
Existing electronic devices lack an efficient method for retrieving and transmitting detailed diagnostic data, including error occurrence information, to mobile terminals, which hinders effective troubleshooting and maintenance.
Innovation Solution
An electronic device equipped with a memory, communication unit, and controller that stores and transmits diagnostic data, including error occurrence time information, operation information, and status information, to a mobile terminal, allowing for easy retrieval and display of diagnostic and detailed diagnostic data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If diagnostic data is stored in a single memory location, then data retrieval is simple, but detailed diagnostic information cannot be efficiently organized and transmitted
Solution Approach 1:
The patent divides diagnostic data into three distinct segments stored in separate memory locations: periodic data (Data1) containing temperature, pressure, and environment information; instantaneous data (Data2) containing voltage, peak current, and motor speed at error occurrence; and post-occurrence data (Data3) containing inverter fault maintenance time and error history. This segmentation allows efficient organization and retrieval of different types of diagnostic information while maintaining data completeness.
2Loss of information
If all diagnostic data is transmitted at once, then complete information is provided, but transmission time and power consumption increase
Solution Approach 1:
The patent implements a dynamic data transmission mechanism where the controller selectively transmits different types of diagnostic data based on the specific error condition and user needs. The communication unit can retrieve and transmit only the relevant data segments (periodic, instantaneous, or post-occurrence data) rather than all data at once, reducing transmission time and power consumption while providing complete information when needed.
3Measurement precision
If detailed diagnostic data is stored with high resolution, then measurement precision is improved, but memory requirements and data processing complexity increase
Solution Approach 1:
The patent applies different data storage and processing qualities to different types of diagnostic information based on their specific requirements. Periodic data (Data1) is stored with comprehensive resolution for trend analysis, instantaneous data (Data2) at error occurrence is stored with high precision for immediate diagnosis, and post-occurrence data (Data3) is stored with appropriate resolution for maintenance tracking. This local quality approach ensures measurement precision where needed while reducing overall data processing complexity.

AI summary
A mobile terminal includes a communication unit, a display, and a controller for performing a control operation to display a screen related to an electronic device, performing a control operation to request for diagnostic data based on an input for a diagnosis mode provided with the screen related to the electronic device, to display a screen of the diagnostic data, and performing a control operation to request for detailed diagnostic data based on an input for a detailed diagnosis mode, and to display a screen of detailed diagnostic data. Thus, the diagnostic data or detailed diagnostic data about the electronic device may be easily displayed.
