Wireless Connection Device Using Terminal State Advertisement Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless connection devices often connect to the closest or most recently connected terminal, rather than the desired terminal, leading to user dissatisfaction in selecting the intended device for communication.
Innovation Solution
A wireless connection device equipped with a terminal state acquiring unit, determination unit, and connection processing unit that uses advertisement signals with terminal state information to determine if a user is actively using a terminal, allowing for precise connection based on user-defined criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If connection is made based on radio field intensity to automatically connect to the closest terminal, then connection speed is improved, but connection accuracy deteriorates (desired terminal may not be connected)
Solution Approach 1:
The patent changes the connection determination parameter from radio field intensity to terminal state information. Instead of measuring signal strength to determine connection target, the system evaluates terminal states (active use, standby, etc.) to accurately identify the desired terminal for connection.
2Stability of the object's composition
If reconnection is made to the most-recently-connected terminal, then connection stability is improved, but connection accuracy deteriorates (desired terminal may not be connected)
Solution Approach 1:
The patent performs preliminary evaluation of terminal states before establishing connection. By assessing terminal states in advance and storing this information, the system can accurately determine the desired connection target rather than simply reconnecting to the most recent terminal.
3Measurement precision
If terminal state information is acquired and processed to determine connection target, then connection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent introduces an advertisement signal as an intermediary carrier that transmits terminal state information from terminals to the wireless connection device. This intermediary mechanism enables accurate terminal identification without requiring complex direct communication or additional hardware between terminals and the connection device.

AI summary
A wireless connection device that performs wireless communication with a terminal which is a communication target by wirelessly connecting to the terminal using a predetermined protocol includes: a terminal state acquiring unit configured to acquire an advertisement signal which is used to cause the wireless connection device to recognize presence of the terminal and which includes terminal state information indicating a state of the terminal; a determination unit configured to determine that wireless connection to the terminal is to be performed when the terminal state information indicates a predetermined state indicating that a user is using the terminal; and a connection processing unit configured to perform a wireless connection process to the terminal to which it is determined that connection is to be performed by the determination unit using the predetermined protocol.
