Solution Overview
Problem
Bluetooth Low Energy (BLE) technology, while effective in reducing power consumption, faces challenges in maintaining continuous connections for devices like remote controllers due to ongoing data transmission/reception, leading to significant power consumption that hinders long-term operation without recharging.
Innovation Solution
Implementing a communication protocol that switches between wireless signals of different intensities, using Bluetooth for low-power harvesting and WiFi for reconnection, allowing devices to enter sleep modes and wake up for reconnection when needed, thereby reducing unnecessary power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If BLE connection is maintained for continuous data transmission/reception, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic connection establishment and disconnection instead of continuous connection. The control device periodically connects to the electronic apparatus to transmit control signals, then disconnects to enter sleep mode. This periodic action pattern maintains communication reliability when needed while significantly reducing power consumption during idle periods.
Solution Approach 2:
The patent dynamically adjusts the connection state between the control device and electronic apparatus based on operational needs. The system transitions between connected and disconnected states, adapting the communication mode to the current operational context. This dynamic approach allows the system to optimize the balance between communication reliability and power consumption.
2Reliability
If wireless signal intensity is increased for reliable communication, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent changes the transmission power parameter dynamically based on connection state. During active communication, the system uses appropriate transmission power to ensure reliability. During sleep mode, transmission is suspended entirely, reducing power consumption. The system adapts the signal intensity parameter to match the operational requirements.
3Stability of the object's composition
If continuous data transmission is performed to maintain BLE connection, then connection stability is improved, but battery life decreases
Solution Approach 1:
The patent implements periodic reconnection cycles instead of continuous data transmission. The control device periodically wakes from sleep mode, establishes connection with the electronic apparatus, exchanges necessary control data, then disconnects and returns to sleep mode. This periodic pattern maintains connection stability when needed while extending battery life through reduced active transmission time.
Solution Approach 2:
The patent extracts the essential communication function from continuous operation. Instead of maintaining constant data transmission, the system extracts only the necessary control signal exchanges and performs them periodically. This extraction approach removes the harmful continuous power consumption while preserving the essential connection stability function.
