Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless data transfer methods, such as physical cables and existing wireless connections like Bluetooth and Wi-Fi, face issues with security and data transmission rate limitations, making them cumbersome and susceptible to security breaches.
Innovation Solution
Establishing a secure and high-bandwidth wireless connection between electronic devices using a unique identifier transmitted via a secure first wireless connection, allowing for a second wireless connection with enhanced security and data transfer capabilities, such as Wi-Fi Direct, which bypasses intermediary access points and provides higher data transmission rates and ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If Wi-Fi connection through access point is used, then data transmission rate is improved, but security vulnerability increases due to susceptibility to security breaches
Solution Approach 1:
The patent introduces a peripheral device as an intermediary that facilitates secure connection establishment. The peripheral device transmits a unique identifier from the second electronic device to the first electronic device, enabling the first device to directly connect to the second device without going through a vulnerable access point, thus maintaining high data transmission rates while improving security
Solution Approach 2:
The patent extracts the connection establishment function from the vulnerable access point infrastructure. By using a peripheral device to transmit device identifiers and enabling direct device-to-device connection, the system removes dependence on intermediary access points that are susceptible to security breaches, while preserving high-speed data transmission capabilities
2Reliability
If Bluetooth connection is used, then security is improved, but data transmission rate decreases limiting transfer to small files
Solution Approach 1:
The patent segments the wireless communication process into two distinct phases: a secure discovery and identifier exchange phase using Bluetooth (or other low-power wireless), and a high-speed data transfer phase using Wi-Fi Direct. This segmentation allows the system to leverage the security advantages of Bluetooth for initial connection establishment while utilizing Wi-Fi Direct's high data transmission rates for actual file transfer
Solution Approach 2:
The patent performs preliminary connection establishment and security verification using a low-power wireless connection before transitioning to high-speed data transfer. The unique identifier is exchanged and connection is authorized through the secure Bluetooth channel first, enabling subsequent high-rate Wi-Fi Direct transmission without compromising security
3Reliability
If physical cable connection is used, then security is improved, but ease of operation decreases making data transfer cumbersome
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless system. By using wireless communications (Bluetooth for discovery, Wi-Fi Direct for data transfer), the system eliminates the need for physical cables while maintaining security through encrypted wireless protocols and direct device-to-device connection, thereby significantly improving ease of operation
