Wireless Connection Setup via BLE Signal Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Establishing a wireless connection between devices, such as transferring files or previewing data, is time-consuming due to the need for manual setup and activation of higher power-consuming protocols like Wi-Fi, especially when using peer-to-peer connections like Wi-Fi Direct.
Innovation Solution
Implementing a method where devices automatically initiate a higher data rate Wi-Fi connection based on detecting specific signals, such as a wakeup or in-use signal, via a lower power consumption protocol like BLE, to reduce setup time and user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If Wi-Fi connection is established for high data rate transmission, then data transmission speed is improved, but power consumption increases and setup time increases
Solution Approach 1:
The system performs preliminary actions by establishing the Wi-Fi connection in advance when the camera is activated or when the second device is detected to be in use. This allows the high-speed connection to be ready before actual data transfer begins, reducing perceived setup time while managing power consumption through conditional activation.
Solution Approach 2:
The system dynamically switches between communication protocols based on operational context. It uses BLE for low-power communication during idle states and transitions to Wi-Fi for high-speed data transfer when needed, optimizing the balance between power consumption and transmission speed throughout the device lifecycle.
2Adaptability or versatility
If Wi-Fi Direct peer-to-peer connection is established, then direct file transfer capability is improved, but connection setup time increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing the Wi-Fi Direct connection when the camera is activated or when the second device is detected to be in use. This preparation happens before the user initiates file transfer, so the connection is already ready when needed, eliminating perceived setup delay.
Solution Approach 2:
The system uses BLE as an intermediary for initial device discovery and communication. This low-power protocol facilitates the initial handshake and triggers the Wi-Fi Direct connection setup, acting as a mediator that enables the high-speed connection without requiring manual user configuration.
3Use of energy by moving object
If manual activation of Wi-Fi is required, then power consumption is reduced, but ease of operation deteriorates
Solution Approach 1:
The system provides self-service by automatically managing the Wi-Fi connection lifecycle. It activates Wi-Fi when the camera is turned on or when a second device is detected via BLE, and manages the connection without requiring user intervention. This maintains ease of operation while controlling power consumption through context-aware activation.
Solution Approach 2:
The system uses feedback from BLE device detection to trigger Wi-Fi activation. When the second device is detected via low-power BLE communication, this feedback signal automatically initiates the Wi-Fi connection process, creating a responsive system that balances power consumption with user convenience based on actual operational needs.

AI summary
A method for establishing a wireless connection comprises initiating, by a first device, a procedure of establishing a first wireless connection of a first communication protocol with relatively higher data rate and higher power consumption, between the first electronic device and a second electronic device, in response to one of: (a) detecting a first signal from a peripheral unit of the first electronic device, the first signal leading the first electronic device to become active and (b) detecting a second signal from the second electronic device via a second wireless connection of a second communication protocol established between the first electronic device and the second electronic device, the second signal indicating that the second electronic device is in use, or in response to (c) detecting the first signal that is detected within a predetermine time after receiving the second signal.
