BTLE Access Control Dynamic Rate Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Access control systems using Bluetooth Low Energy (BTLE) face a trade-off between lock opening speed and battery life, as slowing down communication rates to conserve energy increases the time required to connect, affecting user satisfaction and battery longevity.
Innovation Solution
Implementing a sensor-driven method to dynamically change the BTLE communication rate from a slow to a faster rate upon detection of a person, and reverting to the slow rate after a predefined period or unlock event, optimizing power consumption and performance.

Engineering Contradiction Analysis
1Duration of action of stationary object
If the BTLE communication rate is slowed down to conserve energy, then battery life is extended, but the lock opening speed decreases
Solution Approach 1:
The patent applies dynamics by making the BTLE communication rate adjustable rather than fixed. The access control device dynamically switches between a first communication rate (slower) and a second communication rate (faster) based on environmental conditions detected by sensors. This allows the system to optimize between battery life and lock opening speed according to real-time conditions, resolving the contradiction between extended battery life and maintained opening speed.
Solution Approach 2:
The patent changes the communication rate parameter based on sensor input. When sensors detect specific conditions (such as presence of users or environmental factors), the system transitions from the first communication rate to the second communication rate. This parameter adjustment allows the system to achieve faster lock opening when needed while maintaining energy efficiency during normal operation, thereby resolving the trade-off between battery life and opening speed.
2Productivity
If the communication rate is increased to improve lock opening speed, then user satisfaction increases, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts the communication rate based on sensor-detected conditions. Rather than operating at a constant high rate that would consume excessive energy, the access control device switches to a faster second communication rate only when sensors indicate appropriate conditions (such as user presence). This dynamic adjustment maintains high productivity when needed while minimizing energy consumption during other periods.
Solution Approach 2:
The patent implements periodic monitoring of environmental conditions through sensors, with communication rate adjustments occurring in response to these periodic assessments. The system alternates between different communication rates based on periodic sensor input, achieving high speed performance during relevant periods while conserving energy during other periods, thus resolving the contradiction between productivity and energy use.
