Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices supporting two wireless protocols, such as Bluetooth Classic (BT) and Bluetooth Low Energy (BLE), are typically restricted from simultaneous operation, either by protocol definition or hardware limitations, leading to inconvenient manual mode switching for users seeking seamless voice and notification functions.
Innovation Solution
Implementing a method and system for automatic mode-switching between BT and BLE protocols, allowing seamless transitions without user intervention, using dual separate communication protocol addresses and time-multiplexed connections, enabling a Dual-ID device to support simultaneous voice and data connections by configuring a single physical device as two logical independent devices with separate addresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a device supports both Bluetooth Classic and Bluetooth Low Energy protocols, then the device can provide both voice and notification functions, but the protocols cannot operate simultaneously due to protocol definition or hardware limitations
Solution Approach 1:
The patent implements dynamic protocol switching where the device automatically transitions between Bluetooth Classic and Bluetooth Low Energy modes based on real-time connection status and operational requirements. The system monitors connection events and triggers appropriate protocol switches to maintain simultaneous functionality of both voice and notification features without manual intervention
Solution Approach 2:
The system performs preliminary actions by pre-configuring dual protocol support and establishing connection event listeners before actual communication needs arise. When a connection event is detected, the system has already prepared the switching mechanism to immediately activate the appropriate protocol, minimizing latency and ensuring seamless operation
2Reliability
If manual mode switching is required between Bluetooth Classic and Bluetooth Low Energy, then protocol operation reliability is maintained, but user convenience deteriorates due to explicit mode-switching requirements
Solution Approach 1:
The device implements self-service through automatic protocol switching mechanisms that monitor connection events and autonomously transition between Bluetooth Classic and Low Energy modes. The system detects when a connection event occurs and automatically activates the appropriate protocol without requiring user intervention, thereby maintaining reliability while significantly improving ease of operation
Solution Approach 2:
The system employs feedback mechanisms by continuously monitoring connection status and operational requirements, then using this information to automatically adjust protocol selection. The feedback loop ensures the device responds appropriately to changing conditions while maintaining reliable operation and eliminating manual switching requirements
3Ease of operation
If seamless transitions between Bluetooth modes are implemented, then user convenience is improved, but switching latency increases during mode transitions
Solution Approach 1:
The system performs preliminary actions by pre-establishing connection event listeners and preparing switching mechanisms before actual protocol transitions are needed. When connection events are detected, the switching infrastructure is already in place, allowing for rapid protocol activation that minimizes perceived latency while maintaining seamless user experience
Solution Approach 2:
The implementation rushes through the switching process by directly activating the target protocol upon detecting connection events, bypassing unnecessary intermediate steps. The system quickly transitions from one protocol to another by leveraging pre-configured dual-mode support and optimized switching logic, thereby reducing switching latency while maintaining transition smoothness
4Adaptability or versatility
If dual separate communication protocol addresses are used to enable simultaneous connections, then device versatility is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by assigning separate communication addresses and connection identifiers for Bluetooth Classic and Low Energy protocols. This allows the device to maintain independent connection contexts for each protocol, enabling simultaneous connections while managing complexity through structured address allocation and connection management
Data Source
AI summary
Appearance of simultaneous connections is provided to devices that support two wireless protocols which are not permitted to operation simultaneously. As an example the method and systems disclosed are applied to the communication between a phone and a smartwatch wherein Bluetooth (BT) classic protocol is used for e.g. voice commands and phone calls and Bluetooth low Energy (BLE) protocol is used for data notifications. In a first embodiment of the disclosure automatic mode switching between BT and BLE is provided. In a second embodiment a dual-ID device utilizes separate IDs for both protocols in time multiplexed connections. It operates as logically independent devices with individual ID's although physically it is a single device.
