Solution Overview
Problem
Existing wireless communication methods require obtaining identity information of a target terminal device before establishing a connection, which is inefficient and time-consuming.
Innovation Solution
A method that uses ultrasonic signals to establish a wireless communication connection by obtaining direction information from a user, sending an ultrasonic signal in that direction, receiving a response signal, and determining the type of connection based on distance information to establish a communication link without needing the target device's identity information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If identity information of target terminal device is obtained before sending connection establishment request, then connection can be established with known device, but time required to establish connection increases and efficiency decreases
Solution Approach 1:
The patent applies preliminary action by having the target terminal device broadcast its identity information and send a connection request to the source device before the source device actually needs to establish connection. This pre-positioning of information and preliminary connection setup eliminates the time-consuming step of obtaining target device identity information when connection is needed, directly improving connection establishment efficiency while reducing time loss.
2Ease of operation
If traditional identity-based connection method is used, then connection can be established with specific target device, but complexity of obtaining and managing identity information increases
Solution Approach 1:
The patent applies inversion by reversing the traditional connection initiation approach. Instead of the source device actively seeking and obtaining target device identity information to establish connection, the target device proactively broadcasts its identity and sends connection requests to source devices. This reverses the information flow and operational sequence, making connection initiation simpler for the source device while reducing identity information management complexity.
3Productivity
If ultrasonic signal is used for directional communication, then connection establishment efficiency improves and time is reduced, but additional hardware components and signal processing complexity are required
Solution Approach 1:
The patent applies multi-functionality by utilizing the terminal device's existing speaker and microphone components for dual purposes: traditional audio functions and ultrasonic signal transmission/reception for connection establishment. By making existing hardware perform multiple functions, the patent achieves fast directional connection establishment without requiring additional specialized hardware, thus improving connection speed while minimizing the increase in device complexity.
