Solution Overview
Problem
Existing Bluetooth technologies face challenges in efficiently controlling and managing transmission power across multiple devices, leading to inconsistent service provision and increased latency due to differing transmission powers.
Innovation Solution
A method and apparatus using Bluetooth Low Energy (BLE) technology to establish connections between devices and dynamically adjust transmission powers based on requested values, incorporating a control device that receives and processes power change requests from multiple devices to set a unified transmission power value, while also considering Received Signal Strength Indicator (RSSI) thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If transmission power is increased to extend communication distance, then transmission distance is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic transmission power adjustment where the control device receives power change requests from multiple devices and adjusts transmission power in real-time based on current communication needs, rather than using fixed power levels. This allows the system to optimize between transmission distance and power consumption by adapting power levels to actual requirements.
Solution Approach 2:
The system changes the transmission power parameter dynamically by processing power change requests that include specific power values and change amounts. The control device adjusts transmission power by adding change values to current power levels, enabling flexible optimization of the trade-off between transmission distance and power consumption based on environmental conditions and device needs.
2Adaptability or versatility
If transmission power of each device is adjusted independently to meet individual requests, then service customization is improved, but system complexity increases
Solution Approach 1:
The patent introduces a control device as an intermediary that centralizes the management of transmission power adjustments. Instead of devices adjusting power independently which would create coordination complexity, the control device receives power change requests from multiple devices, processes them centrally, and manages the adjustments, thereby reducing system complexity while maintaining service customization.
Solution Approach 2:
The control device performs multiple functions: it manages connections with multiple devices, processes power change requests from different devices, determines appropriate power adjustments based on various factors, and coordinates the actual power changes. This multi-functional approach consolidates complexity into a single device while enabling customized service for each connected device.
3Reliability
If transmission power changes are processed for multiple devices simultaneously, then service consistency is improved, but processing time increases
Solution Approach 1:
The control device receives and processes power change requests from multiple devices in advance, determining the appropriate transmission power adjustments before actual communication occurs. By pre-processing these requests and establishing power levels proactively, the system ensures service consistency across devices while minimizing processing time during actual communication operations.
