Earbud Bluetooth Connection Switching by Location and Device State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Earbud devices struggle to optimize Bluetooth connections based on the enabled state of the Bluetooth function and location information of counterpart devices, leading to inefficient power consumption and decreased connection speeds.
Innovation Solution
An apparatus and method that utilize sensors and communication interfaces to obtain location information of both earbud devices and determine optimal connection operations, such as page operations or BLE scan operations, based on their relative positions and states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If earbud devices perform page operation and page scan operation simultaneously after booting to establish Bluetooth connection, then connection speed is improved, but power consumption increases significantly
Solution Approach 1:
The patent applies dynamics by making the connection establishment process adaptive rather than static. The system dynamically selects between page operation and BLE advertising based on real-time conditions (whether the counterpart device is in proximity). When the counterpart device is nearby, page operation is used for fast connection; when far away, BLE advertising is used to conserve power. This dynamic adaptation resolves the contradiction between connection speed and power consumption.
Solution Approach 2:
The patent changes the operational parameters of the connection establishment process based on detected conditions. The system monitors the state of the counterpart device (enabled state of Bluetooth function and location information) and adjusts the connection strategy accordingly. By changing parameters such as the type of connection operation (page vs. BLE) and the timing based on detected conditions, the system optimizes both connection speed and power consumption.
2Device complexity
If earbud devices attempt to establish connection without knowing the enabled state of counterpart device, then device complexity is reduced, but connection reliability decreases
Solution Approach 1:
The patent applies preliminary action by performing detection operations before the actual connection establishment. The system first checks whether the counterpart device has enabled its Bluetooth function and determines its location information before initiating the connection process. This preliminary detection ensures that the subsequent connection attempt is reliable, while the complexity added is minimal and justified by the significant improvement in connection success rate.
Solution Approach 2:
The system performs self-service by autonomously determining the optimal connection strategy based on detected conditions without requiring manual intervention or complex configuration. The earbud device automatically monitors the counterpart device's state and selects the appropriate connection method, simplifying the user experience while improving reliability.
3Speed
If earbud devices use legacy Bluetooth connection method, then connection speed is improved, but power consumption increases compared to BLE
Solution Approach 1:
The patent resolves this contradiction by making the connection method dynamic rather than fixed. The system evaluates real-time conditions (proximity detection, enabled state of counterpart device) and dynamically selects between legacy Bluetooth (faster but higher power consumption) and BLE (slower but lower power consumption). This dynamic selection allows the system to optimize the trade-off between speed and power consumption based on actual operational context.
Solution Approach 2:
The system changes the connection parameter (type of Bluetooth protocol used) based on detected conditions. When the counterpart device is in proximity and Bluetooth is enabled, the system uses legacy Bluetooth for fast connection. When the device is far away or Bluetooth is not enabled, the system switches to BLE to conserve power. This parameter change resolves the contradiction by adapting to different operational scenarios.
