Home Appliance Data Interpreter for Privacy-Safe Repair Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional home appliance monitoring systems invade user privacy by collecting and transmitting usage data, potentially exposing sensitive information to unauthorized parties.
Innovation Solution
A method that continuously senses home appliance data, saves it as history logs, and allows retrieval only under authentication, using electronic devices connected via a network, ensuring user privacy and facilitating repair and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If running data of home appliance is continuously collected and transmitted to monitoring unit, then service end can provide good service by acquiring running data, but user privacy information such as usage habits and staying time may be leaked
Solution Approach 1:
The patent extracts only the necessary diagnostic data from the complete running data set. The interpreter selectively retrieves specific history logs related to appliance malfunction rather than transmitting all usage data, thereby maintaining service quality while protecting user privacy.
Solution Approach 2:
The patent introduces an interpreter as an intermediary component between the home appliance and the monitoring unit. This intermediary selectively processes and transmits only relevant diagnostic information, acting as a privacy filter that prevents direct exposure of user usage habits while enabling effective service support.
2Reliability
If all running data is transmitted to monitoring unit for analysis, then complete monitoring capability is achieved, but data transmission load and network bandwidth consumption increase
Solution Approach 1:
The system extracts and transmits only the specific history logs relevant to the reported malfunction rather than all running data. This selective data extraction significantly reduces network bandwidth consumption while maintaining effective monitoring and diagnostic capabilities.
Solution Approach 2:
The patent implements partial action by retrieving only the necessary portion of history logs required for diagnosing the specific malfunction. Instead of transmitting excessive complete data sets, the system performs just enough data retrieval to achieve effective monitoring and service support.
3Ease of repair
If history logs are made accessible for repair purposes, then repairmen can determine usage condition of home appliance, but unauthorized access to user privacy information may occur
Solution Approach 1:
The patent uses the interpreter as an authenticated intermediary that controls access to history logs. The interpreter verifies the identity and authorization of repair personnel before releasing diagnostic data, enabling ease of repair while preventing unauthorized access to user privacy information.
Solution Approach 2:
The system implements self-service authentication where the interpreter automatically verifies credentials and manages access control without requiring manual intervention. This enables authorized repairmen to easily access diagnostic information while maintaining security against unauthorized users.
Data Source
AI summary
A method of obtaining data of a home appliance, which includes the following steps: Sense the home appliance to obtain running data, and transmit the running data to an interpreter; save the running data in a memory of the interpreter as a plurality of history logs; connect a specific electronic device to the interpreter via a network; send a retrieval command to the interpreter; transmit at least one history log to the electronic device according to the retrieval command. With such design, repairmen can only obtain the history logs which are helpful for repairing and maintenance under authentication.
