Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth Low Energy (BLE) communication systems face a trade-off between energy consumption and connection latency, particularly in scenarios where physical proximity is not maintained, leading to inefficient energy use and potential functionality delays.
Innovation Solution
Adjusting the BLE connection interval based on connection data such as distance, location, interference, and motion to optimize energy consumption and latency, using user equipment and communication devices to dynamically adjust the interval according to specific conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the BLE connection interval is decreased to improve connection latency and responsiveness, then the connection latency is reduced, but the energy consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of the BLE connection interval based on real-time conditions. The system monitors connection data including distance, location, interference levels, and motion status, then automatically adjusts the connection interval to optimize the balance between latency and energy consumption. This transforms the static connection interval into a dynamic parameter that adapts to changing environmental and usage conditions.
Solution Approach 2:
The core mechanism involves changing the connection interval parameter based on multiple input factors. When distance exceeds a threshold, the connection interval is increased to save energy. When motion is detected or interference is high, the interval is decreased to maintain connection quality. This parameter adjustment strategy directly addresses the contradiction by making the interval flexible rather than fixed.
2Use of energy by moving object
If the connection interval is increased to reduce energy consumption, then energy consumption is reduced, but the connection latency increases
Solution Approach 1:
The system dynamically adjusts the connection interval based on real-time monitoring of connection data. When the device detects that the user equipment is far away or stationary, it increases the connection interval to reduce energy consumption. When motion is detected or the devices approach each other, the interval is automatically decreased to maintain low latency. This dynamic behavior resolves the contradiction by making the interval adaptive to current conditions.
Solution Approach 2:
The patent changes the connection interval parameter based on multiple conditions including distance thresholds, motion detection, and interference levels. By adjusting this parameter dynamically, the system optimizes the trade-off between energy efficiency and connection responsiveness, allowing longer intervals when possible and shorter intervals when performance is critical.
3Reliability
If the BLE communication maintains a low connection interval to ensure functionality, then connection reliability is improved, but energy consumption increases
Solution Approach 1:
The system implements dynamic connection interval adjustment that maintains reliability when needed while saving energy when possible. By monitoring connection data such as distance, motion status, and interference, the system automatically adjusts the interval to maintain reliable communication during critical moments while using extended intervals during stable, low-risk periods. This resolves the contradiction by making reliability adaptive rather than constant.
Solution Approach 2:
The patent adjusts the connection interval parameter based on multiple factors including distance thresholds, motion detection, and interference levels. When conditions indicate potential connection issues, the interval is decreased to maintain reliability. When conditions are stable and favorable, the interval is increased to reduce energy consumption, thus optimizing the reliability-energy trade-off.
