Bluetooth Reconnection Cycle Adjustment for Power Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable Bluetooth devices frequently disconnect and reconnect with paired communication devices due to unstable connections, leading to high power consumption and reduced device runtime.
Innovation Solution
A method and apparatus that set a connecting cycle based on the count of historical disconnections, adjusting the reconnection interval to conserve power and maintain stable connections, with thresholds for different connection stability scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequent reconnection attempts are initiated when Bluetooth connection is disconnected, then connection reliability is improved, but power consumption increases significantly
Solution Approach 1:
The patent applies dynamics by making the reconnection cycle variable rather than fixed. The system dynamically adjusts the reconnection cycle based on the count of historical disconnections: when disconnection count is low, a shorter cycle is used for quick reconnection; when disconnection count is high, a longer cycle is used to reduce power consumption. This dynamic adjustment resolves the contradiction between connection reliability and power consumption.
Solution Approach 2:
The patent changes the parameter of reconnection cycle time based on the disconnection count. By modifying this key parameter according to connection stability conditions, the system achieves both reliable reconnection (when conditions permit) and power conservation (when disconnections are frequent), thereby resolving the technical contradiction.
2Speed
If reconnection is initiated immediately upon disconnection, then connection restoration speed is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the waiting time before reconnection based on historical disconnection data. Instead of always initiating immediate reconnection, the system adapts the timing based on connection stability, achieving a balance between restoration speed and power consumption.
Solution Approach 2:
The patent implements periodic action by using different reconnection cycles based on disconnection count thresholds. The system alternates between short-cycle reconnection (when stable) and long-cycle reconnection (when unstable), creating a periodic pattern that optimizes both speed and energy usage.
3Reliability
If multiple reconnection attempts are made in unstable environments, then connection reliability is improved, but device runtime decreases due to power consumption
Solution Approach 1:
By changing the reconnection cycle parameter based on disconnection count, the system extends device runtime in unstable environments by using longer cycles when disconnection frequency is high, while maintaining connection reliability through adaptive adjustment rather than fixed aggressive reconnection.
Solution Approach 2:
The dynamic adjustment of reconnection cycles based on historical disconnection data allows the system to preserve battery life (extending runtime) while still attempting reconnections appropriately, resolving the contradiction between reliability and duration of action.
