Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless apparatuses face difficulties in switching to the correct radio wave frequency without a GPS device, as they need to comply with regional regulations, making it challenging to use them in different locations without mounting additional devices.
Innovation Solution
An electronic apparatus with a wireless communication section and a processing section that acquires frequency information from a terminal device with a connection history to an external access point, allowing it to operate as an internal access point and directly connect to the terminal device using that frequency, eliminating the need for a GPS device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a GPS device is mounted to specify the region for frequency switching, then the ability to comply with regional regulations is improved, but the device complexity and cost increase
Solution Approach 1:
The patent introduces a terminal device as an intermediary that stores and provides frequency information to the electronic apparatus. Instead of using GPS to determine location and then looking up frequencies, the terminal device directly provides the necessary frequency information through wireless communication, eliminating the need for GPS hardware while ensuring regional compliance.
Solution Approach 2:
The patent extracts the frequency information storage and provision function from the electronic apparatus itself and places it in the terminal device. The terminal device maintains a history of connection frequencies from external access points, and this information is extracted and used by the electronic apparatus when establishing direct wireless connections.
2Device complexity
If frequency information is acquired from terminal device connection history, then the need for GPS device is eliminated, but the reliance on terminal device data increases
Solution Approach 1:
The system implements a feedback mechanism where the terminal device provides frequency information based on its connection history to external access points. The electronic apparatus uses this feedback information to establish appropriate wireless connections, and the terminal device's ongoing connection history continuously updates the available frequency information for future use.
3Ease of operation
If the electronic apparatus operates as an internal access point using acquired frequency information, then direct connection to terminal device is enabled, but the apparatus must switch between different operational modes
Solution Approach 1:
The electronic apparatus dynamically switches between different operational modes (external access point mode and internal access point mode) based on the connection scenario. When a terminal device connects to an external access point, the electronic apparatus operates as an external access point. When establishing a direct connection using acquired frequency information, it switches to operating as an internal access point, enabling flexible adaptation to different connection requirements.

AI summary
An electronic apparatus includes a wireless communication section configured to perform wireless communication and a processing section configured to perform communication control for the wireless communication section. The processing section performs control for causing the wireless communication section to operate as an internal access point that acquires, from a terminal device having a history of connecting to an external access point, through the wireless communication section, frequency information used for the connection to the external access point and performs the wireless communication using a frequency based on the acquired frequency information and, with the internal access point, directly connecting to the terminal device.
