Bluetooth Device Power Mode Switching for Throughput Trade-offs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
BLE connection intervals pose a challenge in balancing power consumption and throughput, as shortening intervals increases throughput but raises power consumption, while lengthening intervals reduces throughput and increases data transmission times.
Innovation Solution
A method involving a BLUETOOTH device with functional modules for managing power modes and connection parameters, including an initial connecting module, setting module, determining module, selecting module, notifying module, receiving module, and executing module, to dynamically adjust connection intervals and power modes based on communication states to optimize power consumption and throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the connection interval is shortened to increase throughput, then data transmission efficiency is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of connection intervals based on communication conditions. The system transitions from static connection parameters to dynamic adaptation, where the master device adjusts connection intervals in real-time according to data transmission requirements and power consumption constraints, resolving the contradiction between throughput and power consumption
Solution Approach 2:
The patent changes the connection interval parameter dynamically based on communication states. By adjusting this critical parameter according to actual needs, the system optimizes the balance between data transmission efficiency and energy consumption, avoiding the fixed trade-off in traditional BLE connections
2Loss of energy
If the connection interval is enlarged to reduce power consumption, then energy saving is improved, but throughput decreases and data transmission time increases
Solution Approach 1:
The system dynamically adapts connection intervals rather than using fixed enlarged intervals. This allows the system to maintain small intervals when high throughput is needed while using larger intervals when power saving is prioritized, resolving the contradiction between energy saving and throughput maintenance
Solution Approach 2:
The patent implements periodic adjustment of connection parameters based on communication patterns. By analyzing historical transmission data and communication states, the system periodically optimizes connection intervals to achieve both energy efficiency and adequate throughput
3Loss of energy
If the connection interval is enlarged to reduce power consumption, then energy saving is improved, but data transmission time increases
Solution Approach 1:
The patent dynamically changes connection interval parameters based on actual transmission needs. By adjusting this parameter in real-time, the system avoids the fixed trade-off where larger intervals always result in longer transmission times, instead optimizing both power consumption and transmission time according to communication states
