Smart Home Device Authorization via Intermediary Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face complexity and security risks when configuring and using smart home devices in public places, as they need to manually set up networks and delete account information, leading to potential leakage of personal data.
Innovation Solution
A device control method that allows users to authorize another device to use a smart home device without configuring networks or setting personal information, using authorization codes and time-limited access to ensure secure and convenient usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually configure network and delete account information when using smart home devices in public places, then security risk of personal information leakage is reduced, but user operations become complex and time-consuming
Solution Approach 1:
The patent introduces an authorization code as an intermediary mechanism between the user's electronic device and the smart home device. The authorization code enables automatic network configuration and account information management without requiring users to manually perform these operations, thus reducing operational complexity while maintaining security through time-limited access control
Solution Approach 2:
The system performs preliminary actions by automatically configuring the network connection and account information before the user needs to use the smart home device. The authorization code is generated in advance and enables the electronic device to automatically complete network configuration and account setup, eliminating the need for manual pre-configuration operations
2Reliability
If users manually delete account information when leaving a public place, then personal information security is improved, but the operation is complex and users may forget to perform it
Solution Approach 1:
The system implements self-service functionality where the smart home device automatically deletes the account information stored from the second electronic device when the authorization code verification fails or when the system detects that the user has left. This automatic cleanup mechanism eliminates the need for users to manually delete information, ensuring security without requiring additional user operations
Solution Approach 2:
The system employs periodic verification of the authorization code and account information validity. The smart home device periodically checks whether the stored account information is still valid by verifying against the authorization code, and automatically removes invalid information, creating a rhythm of automatic security maintenance without user intervention
3Adaptability or versatility
If users configure network and set personal information for each smart home device, then device functionality is fully utilized, but user operations increase and convenience decreases
Solution Approach 1:
The patent extracts the complex network configuration and account setup operations from the user's manual tasks. The authorization code mechanism separates these configuration operations from the actual device usage, allowing users to simply input the authorization code while the system automatically handles network configuration, account information retrieval, and device pairing, thus maintaining full device functionality while dramatically reducing user operations

AI summary
A device control method includes a first electronic device that configures a network for a home device using a first home application logged in using a first account, sends, in response to a first user operation, an authorization request to a device server, and receives a first authorization code; the home device receives the first authorization code; the first electronic device outputs the first authorization code; the device server stores second personal information corresponding to the second account; a second electronic device sends account information of the second account and a second authorization code to the home device, wherein a second home application is installed on the second electronic device and is logged in using a second account; the home device performs verification on the second authorization code based on the first authorization code, and when the verification succeeds, stores the account information of the second account.
