Acquiring Authority for Electricity-Consuming Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when they forget passwords for household appliances controlled by terminal devices, as other devices cannot communicate with them without the password, leading to inaccessible control.
Innovation Solution
A method and device for acquiring using authority, where a first terminal device establishes communication with an electricity-consuming device using wireless technologies like Bluetooth, WIFI, or Zigbee, allowing the accessing message to be saved and shared with other terminal devices without manual input or password authentication, enabling flexible and convenient access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual password input is required for terminal device communication, then security is improved, but ease of operation deteriorates when users forget passwords
Solution Approach 1:
The patent introduces a first terminal device as an intermediary that stores the accessing message and automatically transmits it to a second terminal device. This mediator eliminates the need for manual password input while maintaining secure access, as the intermediary device handles the authentication credentials and facilitates communication between terminals.
Solution Approach 2:
The accessing message is pre-configured and stored in the first terminal device before actual communication needs arise. This preliminary setup allows the second terminal device to automatically obtain the accessing message without requiring users to manually input or remember passwords at the moment of access.
2Reliability
If password authentication is required for establishing communication, then security is improved, but device complexity increases due to authentication mechanisms
Solution Approach 1:
The patent extracts the authentication mechanism from the communication establishment process. Instead of requiring password authentication during communication setup between the second terminal device and electricity-consuming device, the accessing message is obtained from the first terminal device, separating the authentication credential storage from the communication process.
3Ease of operation
If accessing message is stored in first terminal device, then ease of operation is improved for other devices, but information security risk increases
Solution Approach 1:
The first terminal device acts as a controlled intermediary that selectively provides accessing messages to authorized second terminal devices. This intermediary approach enables easy access for legitimate users while maintaining security through controlled information distribution, as the intermediary can verify recipient authorization before transmitting sensitive credentials.

AI summary
The present disclosure relates to a method and a device for acquiring a using authority. The method includes: acquiring an accessing message sending instruction including a service set identifier (SSID) and a password of an electricity-consuming device 3; and sending the accessing message of the electricity-consuming device to a second terminal device 2 in accordance with the accessing message sending instruction, in which the accessing message is used to establish a communication between the second terminal device and the electricity-consuming device.
