Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices often fail to receive notification messages from mobile terminals when they are out of range due to the limited communication range of Bluetooth technology, leading to missed alerts and messages.
Innovation Solution
A method and apparatus that enable a wearable device to establish communication links with a mobile terminal using multiple protocols, including short-distance and long-distance wireless communications, and connect to a network server if direct links fail, ensuring timely receipt of notification messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth protocol is used for communication between wearable device and mobile terminal, then power consumption is reduced and device complexity is minimized, but communication range is limited to 10 meters causing missed notifications
Solution Approach 1:
The wearable device is equipped with multiple communication modules (Bluetooth module and Wi-Fi module) that can be selectively activated based on communication needs. The system universally supports multiple communication protocols, allowing it to adapt to different communication scenarios - using Bluetooth for low-power short-range communication and Wi-Fi for extended-range communication when Bluetooth is unavailable.
Solution Approach 2:
A server acts as an intermediary between the mobile terminal and the wearable device when direct Bluetooth communication is not available. The server receives notification messages from the mobile terminal, stores them, and forwards them to the wearable device via Wi-Fi communication, enabling indirect communication when direct links are broken.
2Adaptability or versatility
If multiple communication protocols and modules are added to extend communication range, then adaptability and communication capability are improved, but device complexity and power consumption increase
Solution Approach 1:
The communication system dynamically selects and switches between different communication protocols and modules based on real-time conditions. The wearable device monitors Bluetooth connection status and automatically switches to Wi-Fi module when Bluetooth connection is lost or unavailable, and switches back to Bluetooth when connection is restored, making the system adaptable without requiring constant high complexity.
Solution Approach 2:
The patent extracts the core communication function from a single Bluetooth module and separates it into independent communication modules (Bluetooth module and Wi-Fi module). This modular extraction allows the system to use only the necessary communication capability for each scenario, reducing overall system complexity while maintaining versatility.
3Device complexity
If Bluetooth communication is used, then device simplicity is maintained, but notification messages are missed when mobile phone is out of range
Solution Approach 1:
The system implements beforehand cushioning by preparing alternative communication paths (Wi-Fi module and server intermediary) in advance before Bluetooth connection fails. When Bluetooth connection is lost, the pre-configured Wi-Fi module and server connection can immediately take over, preventing notification message loss without requiring complex real-time decision-making.
