Router-Based Appliance Identification via Packet Scoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing household electric appliances connected to a network require subscription to a support service and manual registration, making it difficult for users to initiate management and maintain privacy of appliance information.
Innovation Solution
An information processing device that transmits request packets to connected electric appliances, receives response packets, compares them with stored definition files, and determines the appliance type based on scoring, allowing for automatic identification without user participation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a support service via the Internet is used to manage household electric appliances, then the management of electric appliances can be achieved, but it requires subscription and makes it difficult for users to maintain privacy of appliance information
Solution Approach 1:
The patent introduces a router as an intermediary device that mediates between electric appliances and external networks. The router performs appliance identification and information management locally, preventing direct exposure of appliance details to external support services while still enabling management functionality. This resolves the contradiction by allowing appliance management without requiring users to subscribe to external services that would compromise privacy.
2Reliability
If a support service is utilized for appliance management, then service support can be obtained, but manual registration is required and users cannot initiate management proactively
Solution Approach 1:
The patent implements self-service functionality where the router automatically performs appliance identification, classification, and information management without requiring manual user registration or external support service intervention. The system proactively manages appliances by automatically receiving appliance information, comparing it against stored definition files, and organizing appliance data. This eliminates the need for manual registration while maintaining reliable management capabilities.
3Reliability
If manual registration and service subscription are required, then support service functionality can be provided, but the complexity of the management system increases
Solution Approach 1:
The patent extracts the support service functionality from external servers and relocates it to the local router. By taking out the identification and management functions from external services and implementing them locally, the system eliminates the need for complex subscription mechanisms and manual registration processes. The router maintains a local database of appliance definition files and performs all identification operations locally, significantly reducing system complexity while maintaining full functionality.
Data Source
AI summary
A device, a method and a server for performing device identification of electric appliances connected to a network are provided. An information processing device, to which electric appliances are communicably connected via a network, receives a packet at least containing a packet for checking the status of a communication port of the electric appliance. The information processing device stores definition files defined for each electric appliance in advance, compares the received packet with the definition files for each electric appliance, scores the packet, extracts a definition file with a highest score, and determines a type of the electric appliance from the extracted definition file.
