Server-Based Sensor Data Analysis for Home Appliance Performance Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack methods to analyze data for detecting degraded performance and providing user guides before failures occur, and there is no method to determine if users use the devices correctly, leading to inconvenient contact with after-sales services.
Innovation Solution
A server and home appliance system that receives and analyzes data from sensors to detect performance changes by comparing data over predetermined periods, providing user guide information on detected issues, including whether the issue is repairable by the user or requires professional assistance, and offering information on nearest after-sales service centers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data analysis and performance monitoring functions are added to electronic devices, then user guidance and early failure detection are improved, but device complexity increases
Solution Approach 1:
The patent introduces a server as an intermediary that performs complex data analysis and performance monitoring. The electronic device only needs to collect sensor data and transmit it to the server, which then analyzes the data and provides guidance to the user. This transfers the complexity from the device to the server, maintaining reliability improvement while minimizing device complexity increase.
Solution Approach 2:
The system enables self-service by automatically monitoring device performance and providing user guidance without requiring manual intervention. The server continuously analyzes sensor data and autonomously determines when performance degradation occurs, eliminating the need for users to manually check device status or contact support for basic diagnostics.
2Measurement precision
If comprehensive sensor data collection is implemented, then performance change detection accuracy is improved, but energy consumption increases
Solution Approach 1:
The system implements partial data collection by selectively monitoring only the sensor data necessary for detecting performance changes. Rather than continuously collecting all possible sensor data, the system focuses on specific parameters relevant to the device's function, achieving adequate measurement precision while minimizing energy consumption.
Solution Approach 2:
The patent employs periodic data collection rather than continuous monitoring. Sensors collect data at predetermined intervals, which is then transmitted to the server for analysis. This periodic approach maintains sufficient measurement precision for detecting performance degradation while significantly reducing energy consumption compared to continuous data collection.
3Duration of action of stationary object
If user guide information is provided for performance maintenance, then device lifespan is extended, but information processing requirements increase
Solution Approach 1:
The patent extracts only the essential information needed for user guidance from the comprehensive sensor data analysis. The server processes the full dataset to understand device performance but extracts and transmits only the critical performance indicators and corresponding user actions needed. This minimizes information processing requirements for the device and user interface while still providing effective guidance for extending device lifespan.

AI summary
Disclosed is a method for providing information in a server. Said method for providing information in a server includes: a step for repeatedly receiving at preset intervals, data related to a plurality of sensors provided in an electronic device; a step for storing the data received at the preset intervals; a step for comparing data corresponding to a first period and data corresponding to a second period among the stored data, and thereby sensing a change in the performance of the electronic device; and a step for providing guidance information corresponding to the sensed change in performance to a user terminal device which corresponds to the electronic device.
