Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless connection methods between vehicles and nearby devices are prone to unintended connections and insufficiently handle connection failures, lacking efficient active coping mechanisms.
Innovation Solution
An apparatus and method that includes a processor and communication module to monitor pairing mode operations, generate and broadcast messages with universal and account keys, adjust transmission power based on attenuation calculations, and manage connection attempts to prevent unintended connections and ensure efficient connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vehicle broadcasts a connection request message to enable wireless connection with nearby devices, then connection capability is improved, but the vehicle may connect to unintended devices due to lack of identification verification
Solution Approach 1:
The patent introduces an account key as an intermediary element that mediates between the vehicle and nearby devices. The account key is extracted from the nearby device's account information and included in the connection request message, serving as a verification mechanism to ensure the vehicle connects to the intended device without compromising connection ease
Solution Approach 2:
The patent performs preliminary extraction and inclusion of the account key in the connection request message before the actual connection is established. This preliminary action ensures that verification information is prepared in advance, preventing unintended connections while maintaining operational simplicity
2Adaptability or versatility
If the connection procedure follows the nearby device's operating system operations, then compatibility is improved, but active coping with connection failures and various situations is insufficient
Solution Approach 1:
The patent implements a feedback mechanism where the vehicle actively monitors connection status and sends follow-up messages based on connection outcomes. When connection fails or the nearby device is unavailable, the vehicle detects this state and transmits a new connection request message to re-establish the connection, providing active coping rather than passive reliance on the nearby device's OS
Solution Approach 2:
The patent makes the connection procedure dynamic by allowing the vehicle to adapt its behavior based on real-time connection status. The system transitions from a static, OS-dependent procedure to a dynamic process where the vehicle actively responds to connection failures and environmental changes
3Reliability
If the vehicle waits for user boarding before establishing connection, then connection accuracy is improved, but connection time is increased
Solution Approach 1:
The patent performs preliminary connection establishment by broadcasting the connection request message with the account key before the user boards the vehicle. This preliminary action allows the nearby device to be ready for connection in advance, reducing connection time while maintaining accuracy through pre-verified identification information
Data Source
AI summary
An apparatus and a method for wireless device connection are disclosed. The apparatus includes a memory that stores information of a nearby device having a pairing history and a processor that monitors reception of a pairing mode operation command. The processor generates a first message to include a universal key in response to receiving the pairing mode operation command and generates a second message to include an account key of the nearby device having the pairing history when the pairing mode operation command is not received. The apparatus further includes a communication module that broadcasts the first message or the second message under control of the processor.
