Solution Overview
Problem
Existing refrigerators struggle to detect abnormalities at an early stage, as they primarily rely on single measurement elements like disconnection and current/voltage abnormalities, making it difficult to accurately diagnose issues before they impact temperature maintenance.
Innovation Solution
An electronic device with a communicator and processor that divides the refrigerator's operation into event and normal sections based on received information, comparing internal temperatures and adjusting threshold values to determine abnormalities, and gathering additional data from surrounding devices to pinpoint issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple measurement elements are used to detect refrigerator abnormalities, then measurement precision and early detection capability improve, but device complexity increases
Solution Approach 1:
The patent segments the refrigerator operation into event sections (door opening/closing) and normal sections, and further divides the detection process into multiple stages: preliminary detection using basic temperature thresholds, followed by detailed analysis using multiple measurement elements (temperature, humidity, door opening frequency, compressor operation) only when needed. This segmented approach improves detection accuracy while avoiding continuous high-complexity monitoring.
Solution Approach 2:
The system performs preliminary abnormality detection using simple temperature threshold comparisons during normal operation. Only when abnormalities are suspected or during event sections does the system activate more complex multi-element analysis. This preliminary action allows early detection of obvious issues while reserving complex measurement resources for critical situations.
2Reliability
If continuous monitoring of multiple parameters is performed, then reliability of abnormality detection improves, but energy consumption increases
Solution Approach 1:
The system employs periodic monitoring where basic temperature checks occur continuously at low intensity, while comprehensive multi-parameter monitoring is activated periodically during event sections or when abnormalities are detected. This periodic intensification maintains high detection reliability while avoiding constant high-energy consumption.
Solution Approach 2:
Simple temperature threshold monitoring serves as a preliminary, low-energy screening mechanism. Only when this preliminary monitoring detects potential issues does the system activate energy-intensive multi-parameter monitoring. This ensures reliable detection while minimizing overall energy consumption by keeping complex monitoring dormant during normal operation.
3Measurement precision
If detailed analysis of event section and normal section is performed, then measurement precision improves, but loss of time in processing increases
Solution Approach 1:
The patent segments the operation timeline into event sections (door opening/closing periods) and normal sections, applying different analysis depths to each. Event sections receive detailed multi-parameter analysis due to their critical nature, while normal sections use simpler monitoring. This segmented processing maintains high precision for critical events while reducing processing time during stable periods.
Solution Approach 2:
The system applies partial detailed analysis only to relevant sections (event sections or sections with detected anomalies) rather than performing exhaustive analysis on all data continuously. This partial action maintains high detection precision where needed while significantly reducing overall processing time by skipping detailed analysis during clearly normal periods.
Data Source
AI summary
An electronic device is disclosed. The electronic device of the present invention comprises a communication unit and a processor for receiving information on a refrigerator from the refrigerator through the communication unit, dividing an operation section of the refrigerator into an event section and a normal section on the basis of the received information, and determining whether the refrigerator is abnormal on the basis of a state of the refrigerator in the normal section or the event section among the received information. The event section includes a section from a time point when a door of the refrigerator is opened to a time point when the temperature of the refrigerator reaches a predetermined temperature after the door is closed, and the normal section includes a section from a time point when the temperature of the refrigerator reaches the predetermined temperature to a time point before the door is opened.
