Communication Device BLE Interval Switching for Responsive Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth Low Energy (BLE) communication is not suitable for applications requiring high responsiveness due to its lower responsiveness and power consumption trade-offs.
Innovation Solution
A communication device and system that utilize vibration or utterance detection as triggers to dynamically adjust the Connection Interval for BLE, allowing for higher responsiveness while minimizing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a longer Connection Interval is used for BLE communication, then power consumption is reduced, but responsiveness deteriorates
Solution Approach 1:
The Connection Interval is made dynamically adjustable based on detected user actions. The system transitions from a static connection interval to a dynamic one that changes according to operational context, allowing optimization between power consumption and responsiveness based on real-time needs.
Solution Approach 2:
The patent changes the parameter of Connection Interval based on detected actions. When a user action is detected, the system changes the connection interval parameter to a shorter value to improve responsiveness. When no actions are detected, it maintains a longer interval to conserve power, thus resolving the contradiction through parameter adaptation.
2Speed
If a shorter Connection Interval is used for BLE communication, then responsiveness is improved, but power consumption increases
Solution Approach 1:
The system uses periodic monitoring of user actions to determine when to switch connection intervals. Instead of continuously using a short interval, it periodically checks for user actions and only switches to short interval when needed, thus reducing overall power consumption while maintaining responsiveness when required.
Solution Approach 2:
The connection interval parameter is changed from a fixed value to a variable one that adapts based on detected user actions. This allows the system to use shorter intervals only when necessary for responsiveness, while maintaining longer intervals during idle periods to conserve power.
