Server-Mediated Communication Path for Wearable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable intelligent devices often lose communication functionality when moved beyond the 10-meter range of their connected mobile phones due to Bluetooth connection limitations, restricting their use as communication tools.
Innovation Solution
Implementing a communication method that switches between direct Bluetooth communication and indirect communication via a server using Wi-Fi or cellular networks when devices are out of Bluetooth range, allowing seamless data transmission and reconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth communication is used for direct connection between wearable intelligent devices and mobile phones, then communication reliability is improved within short range, but communication distance is limited to no more than 10 meters
Solution Approach 1:
The patent introduces a server as an intermediary component to relay communication between the wearable intelligent device and mobile phone when direct Bluetooth connection is unavailable. The server receives data from the wearable device via alternative networks (Wi-Fi/cellular) and forwards it to the mobile phone, enabling communication beyond Bluetooth range while maintaining reliability.
Solution Approach 2:
The system dynamically changes communication parameters by switching between different communication modes based on distance and connection status. When Bluetooth connection is available, it uses direct Bluetooth communication; when distance exceeds 10 meters, it switches to server-mediated communication via Wi-Fi or cellular networks, thus adapting to different range requirements.
2Device complexity
If wearable intelligent devices are equipped with only Bluetooth connection, then device complexity is reduced, but adaptability to different communication scenarios is limited
Solution Approach 1:
The wearable intelligent device is designed with multi-functionality by incorporating both Bluetooth and alternative communication capabilities (Wi-Fi, cellular networks). This allows the device to adapt to different communication scenarios - using Bluetooth for short-range direct connection and alternative networks for long-range or server-mediated communication, thus enhancing versatility without significantly increasing complexity.
3Reliability
If direct Bluetooth connection is lost when devices are positioned beyond 10 meters, then communication function is lost, but seamless connection is expected for further exploration of applications
Solution Approach 1:
The system performs preliminary actions by establishing alternative communication paths through the server before direct Bluetooth connection is completely lost. When distance increases, the wearable device proactively switches to server-mediated communication mode, ensuring seamless transition and maintaining communication continuity without interrupting user experience.
Data Source
AI summary
The present invention provides a communication method and a communication system between a first computing device and a second computing device. In response to link disconnection of a first communication link mode between the first computing device and the second computing device, data from the second computing device is received from a server, and/or data addressed to the second computing device is transmitted to the server by a second communication link mode. Accordingly, a seamless connection between the first computing device and the second computing device can be established even if they are positioned so far away from each other that the connection of the first communication link mode between the two has been disconnected.
