Solution Overview
Problem
Conventional wireless network technologies, such as IR and RF, face issues with geometric growth in data transactions as the number of devices increases, making them impractical, and require complex, time-consuming operational steps for establishing connections, which deters widespread adoption.
Innovation Solution
A method for automatically establishing wireless network communication between devices by generating an activation signal, checking and turning on the wireless connection module, searching and identifying compatible devices, and performing data exchange within a predetermined time window, with authentication and termination of connections managed to simplify the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional RF technologies are used to enable wireless communication between multiple devices, then wireless connectivity is achieved, but complex and time-consuming operational steps are required including manual activation, device exploration, selection, and termination
Solution Approach 1:
The system performs preliminary actions by automatically activating the wireless connection module and initiating device search when a user activates a function requiring wireless communication. This eliminates the need for users to manually turn on wireless capabilities or search for devices, as these actions are performed automatically before the actual data exchange begins.
Solution Approach 2:
The wireless connection establishment process serves itself by automatically managing activation, device discovery, selection, and termination without user intervention. The system monitors its own state and performs necessary actions autonomously, such as turning on the wireless module when needed and terminating connections after data exchange completion.
2Productivity
If IR communication is used between multiple devices, then data exchange is possible, but the number of transactions grows geometrically as the number of devices increases
Solution Approach 1:
The system merges multiple one-to-one IR communication channels into a single RF communication channel that can handle multiple devices simultaneously. By using RF technology with broadcast and multicast capabilities, the system combines what would otherwise require multiple separate IR transactions into a unified communication framework, reducing the total number of transactions needed.
Solution Approach 2:
The wireless connection module is designed to perform multiple functions including device search, device selection, authentication, and data exchange within a single unified protocol framework. This multi-functional approach replaces the need for separate specialized protocols for each transaction type, thereby reducing overall system complexity.
3Reliability
If manual activation and configuration of wireless networking is required, then connection control is possible, but the learning curve becomes insurmountable to many users
Solution Approach 1:
The system performs self-configuration and self-authentication by automatically comparing activation reference times between devices and establishing connections without user input. The wireless connection module monitors system states and autonomously manages the entire connection lifecycle, making the process as simple as pressing a single activation key while maintaining secure controlled connections.
Solution Approach 2:
The system performs preliminary authentication and connection setup automatically by comparing activation reference times before data exchange begins. This preliminary action ensures secure controlled connections are established in advance, so users only need to trigger the process without needing to understand or configure any parameters.
Data Source
AI summary
Method for establishing wireless networks between devices is disclosed. When a first device is activated to establish a wireless network with other devices, a first activation reference time is recorded. At least one second device that has at least one compatible networking capability is searched for and identified. When the second device is activated to establish wireless network with other devices, a second activation reference time also is recorded. The first and second activation reference times are compared to determine whether they fall into the same time window. The offset between the system time of the first device and that of the second may be factored into the calculation to further enhance the accuracy. If the first and second activation reference times are in the same time window, the authentication of wireless network is established between the devices.
