Innovation Solution
A method and system for wirelessly communicatively coupling a wearable computing device to a host computing device using multiple personal area networks (PANs), such as Bluetooth Low Energy and Bluetooth, allowing the device to select the appropriate coupling procedure based on the host device's type, operating system, and network, enabling efficient communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a wearable computing device uses a single wireless coupling method to communicate with host computing devices, then the device complexity is reduced, but the adaptability to different host devices and operating systems deteriorates
Solution Approach 1:
The wearable computing device dynamically selects and switches between different coupling procedures (first coupling procedure for BLE, second coupling procedure for Bluetooth) based on the host device type and operating system detected during the pairing process, allowing the system to adapt its communication method in real-time rather than being fixed to a single approach
Solution Approach 2:
The wearable device is designed with multi-functionality by supporting multiple coupling procedures simultaneously - it can perform both BLE-based coupling (first procedure) and Bluetooth-based coupling (second procedure), making it universally compatible with various host devices including mobile computing devices and other types of hosts regardless of their operating system or preferred communication protocol
2Adaptability or versatility
If the wearable computing device transmits advertisement packets on multiple personal area networks simultaneously, then the connectivity and compatibility with host devices is improved, but the energy consumption increases
Solution Approach 1:
The device performs preliminary actions by transmitting advertisement packets on both BLE and Bluetooth networks simultaneously to proactively announce its presence and capabilities to potential host devices, allowing any host that supports either protocol to detect and initiate pairing without requiring the wearable to switch networks or wait for specific conditions
Solution Approach 2:
The system implements self-service by automatically selecting the appropriate coupling procedure based on which network receives the response - the wearable device autonomously determines whether to proceed with the first coupling procedure (BLE-based) or second coupling procedure (Bluetooth-based) without user intervention, optimizing energy usage by committing to one protocol once a response is received
3Reliability
If the wearable computing device supports multiple coupling procedures, then the reliability of communication establishment is improved, but the ease of operation deteriorates
Solution Approach 1:
The system uses feedback mechanisms where the wearable device monitors which personal area network (BLE or Bluetooth) receives the response to its advertisement packets, and based on this feedback information, automatically selects the appropriate coupling procedure - this feedback-driven selection ensures reliable communication establishment while keeping the operation simple for the user

AI summary
Systems, devices, and methods of wirelessly communicatively coupling a wearable computing device to a host computing device are disclosed. The wearable computing device transmits a first advertisement packet via a first personal area network and a second advertisement packet via a second personal area network. The wearable computing device receives a response to one of the first advertisement packet and the second advertisement packet. Based on the response, the wearable computing device selects one of a first coupling procedure and a second coupling procedure to perform. The wearable computing device performs the selected coupling procedure with the host computing device.
