Wireless Device Connection via Power State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication methods for connecting devices, such as those using wireless LAN, face challenges in accurately detecting and connecting devices without mistakenly detecting neighboring devices, leading to potential privacy issues and complicated network name input procedures.
Innovation Solution
The method involves detecting existing communication devices, examining their power supply states, prompting the user to turn on the power supply of the intended device, and then connecting to the device with a turned-on power supply, eliminating the need for network name input and reducing mistaken connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used to connect devices without physical cables, then ease of device movement and connection is improved, but the risk of mistakenly detecting neighboring devices increases
Solution Approach 1:
The system performs preliminary actions by displaying detected devices and their power supply states before actual connection occurs. The user is prompted to turn on the power supply of the intended device, and the system monitors for this action before establishing connection, preventing mistaken connections to neighboring devices.
Solution Approach 2:
The system provides feedback by displaying the detected devices and their power supply states on a screen. This feedback loop allows the user to identify the correct device and confirm connection intent, improving detection accuracy while maintaining wireless convenience.
2Ease of operation
If conventional wireless detection methods are used, then device connection is simplified, but privacy protection is compromised due to detection of neighboring devices
Solution Approach 1:
The system displays detected devices and their power supply states before connection, allowing users to identify and select only their own devices. This preliminary identification step prevents unauthorized access to neighboring devices while maintaining connection simplicity.
Solution Approach 2:
The power supply state monitoring acts as an intermediary verification mechanism. The system waits for the user to turn on the power supply of the intended device before establishing connection, serving as a mediator that confirms connection intent and prevents privacy violations.
3Productivity
If wireless LAN connection is established without power supply state verification, then connection speed is improved, but connection accuracy deteriorates
Solution Approach 1:
The system periodically monitors the power supply state of detected devices after initial detection. This periodic monitoring allows the system to maintain connection readiness while verifying device identity through power state changes, balancing connection speed with accuracy.
Solution Approach 2:
The system uses feedback from power supply state monitoring to confirm connection accuracy. By detecting when the user turns on the power supply of the intended device, the system ensures accurate connection while maintaining relatively fast connection establishment.

AI summary
A user is prompted to turn on power supply of a device to be connected with a screen. When it is detected that the power supply is turned on, the screen is displayed for confirming a user whether the device whose power supply is turned on should be connected or not. Thus, connection is carried out. With such a method, a communication connection method capable of selecting a device to be connected reliably is provided.
