Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in easily forming networks between devices due to different setting configurations and the requirement of Near Field Communication (NFC) technology, which increases manufacturing costs and is not applicable to devices without NFC readers, necessitating a simpler method for connecting devices via Wi-Fi networks.
Innovation Solution
A system and method for connecting devices via a Wi-Fi network by allowing an external device to access an Access Point (AP) through receiving and providing connection information, including Service Set Identifier (SSID) and MAC address, and using password information displayed on the device or remote controller for secure access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If NFC technology is used to form networks between devices, then network formation capability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts the NFC component from the network formation process and replaces it with standard Wi-Fi technology. By removing the requirement for NFC readers and using universally available Wi-Fi connectivity, the solution eliminates the complexity and cost associated with NFC hardware while maintaining network formation capability between devices.
Solution Approach 2:
The patent employs a temporary ad-hoc network formed through Wi-Fi Direct or peer-to-peer connection that dissolves after data transfer. This approach uses inexpensive, universally available Wi-Fi technology instead of costly NFC hardware, achieving the same network formation function through a more economical and accessible means.
2Adaptability or versatility
If NFC technology is used to form networks between devices, then network formation capability is improved, but manufacturing cost increases
Solution Approach 1:
The patent removes the NFC component from the device specification and replaces it with standard Wi-Fi connectivity. This extraction eliminates the need for expensive NFC readers during manufacturing, significantly reducing device cost while preserving the ability to form networks between devices through Wi-Fi technology.
Solution Approach 2:
The solution uses inexpensive Wi-Fi based temporary networks instead of costly NFC technology. By leveraging universally available Wi-Fi connectivity and standard wireless communication protocols, the patent achieves network formation capability without the manufacturing cost premium associated with NFC hardware integration.
3Adaptability or versatility
If different setting configurations are required for devices, then device functionality is improved, but ease of operation deteriorates
Solution Approach 1:
The patent establishes a universal Wi-Fi based network formation mechanism that works across all device types without requiring device-specific configuration. By using standard Wi-Fi protocols and connection methods, the system enables diverse devices to communicate seamlessly through a common interface, eliminating the need for users to navigate different setting configurations for each device pair.

AI summary
A system and a method of connecting devices via a Wireless-Fidelity (Wi-Fi) network are provided. The method of communication-connecting an external device to an Access Point (AP) via a Wi-Fi network is performed by a device and includes operations of receiving device information of the external device from the external device that operates in an AP mode, accessing the external device that operates in the AP mode, by using the device information, and providing connection information relating to the AP to the external device, and wherein, when the connection information is provided to the external device, the external device terminates operating in the AP mode, and the external device then accesses the AP based on the connection information.
