Master-Slave Wireless Network Setup via Near Field Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when trying to establish wireless communication through an access point, especially when the access point is out of reach, as they need to manually input setting information such as IDs and key information, which can be cumbersome and impractical.
Innovation Solution
A wireless communication system where a master communication apparatus stores and transfers setting information to a slave communication apparatus via near field communication, allowing the slave to obtain the necessary information for accessing the access point without direct user input or manual registration, enabling wireless communication through the access point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually input setting information (IDs and key information) to establish wireless communication through an access point, then the wireless communication can be established, but the operation becomes cumbersome and inconvenient, especially when the access point is out of reach
Solution Approach 1:
The master communication apparatus stores setting information (access point IDs and key information) in advance in its storage unit. When a slave communication apparatus needs to connect to the access point, it can obtain this pre-stored setting information from the master apparatus via near field communication, eliminating the need for users to manually input the information again.
Solution Approach 2:
The master communication apparatus acts as an intermediary between the access point and the slave communication apparatus. Instead of the slave apparatus directly obtaining setting information from the access point (which requires user presence near the access point), the master apparatus retrieves and transfers the setting information to the slave apparatus through near field communication, which can be performed at a distance.
2Ease of operation
If users manually register setting information in communication apparatuses, then the apparatus can access the wireless network, but the process is impractical when the access point is located outside the user's reach
Solution Approach 1:
The master communication apparatus serves as a mediator that bridges the gap between the inaccessible access point and the slave communication apparatus. The master apparatus retrieves setting information from the access point using its wireless communication capability, then transfers this information to the slave apparatus via near field communication, simplifying the process for users who cannot physically reach the access point.
Solution Approach 2:
The master communication apparatus automatically retrieves and manages setting information from the access point without requiring direct user intervention for each retrieval operation. The apparatus maintains this information in its storage unit and can automatically transfer it to slave apparatuses that need to connect to the network.
3Adaptability or versatility
If setting information is transferred via near field communication between communication apparatuses, then users can obtain necessary information without direct access to the access point, but requires a master-slave communication architecture
Solution Approach 1:
The master communication apparatus is designed with multi-functionality: it can perform wireless communication with the access point, store setting information in its storage unit, and perform near field communication with slave apparatuses. This universal design allows a single apparatus to fulfill multiple roles in the communication system.
Solution Approach 2:
The master-slave architecture creates a hierarchical intermediary structure where the master apparatus mediates between the access point and multiple slave apparatuses. This architecture allows setting information to be efficiently distributed to multiple devices through a single master apparatus, reducing the overall complexity compared to each device independently connecting to the access point.

AI summary
A wireless communication system includes an access point, a master communication apparatus, and a slave communication apparatus, and the master communication apparatus and the slave communication apparatus perform wireless communication through the access point. The master communication apparatus stores setting information necessary for accessing the access point; performs wireless communication through the access point using the stored setting information; and performs near field communication with the slave communication apparatus to transmit the stored setting information to the slave communication apparatus in response to a setting information request received from the slave communication apparatus via near field communication. The slave communication apparatus performs near field communication with the master communication apparatus to transmit the setting information request to the master communication apparatus; receives the setting information from the master communication apparatus via near field communication; stores the setting information; and performs wireless communication through the access point using the setting information.
