Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RF transceivers in remote control devices consume excessive power even when not receiving signals, leading to reduced battery life, especially in devices with limited power sources.
Innovation Solution
A wireless signal transceiver device incorporating an RF transceiver, microcontroller, and a wake-up module that operates in sleep modes to minimize power consumption, where the wake-up module with lower power consumption generates a wake-up signal to activate the RF transceiver only when necessary, using a noise filter, bandpass filter, signal amplifier, and wake-up filter to convert and amplify trigger signals into wake-up signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the RF transceiver is kept in the working status to enable continuous control of home appliances, then the ease of operation is improved, but the power consumption increases
Solution Approach 1:
The RF transceiver dynamically switches between working status and sleeping status based on whether control signals are being received. This dynamic state change allows the system to maintain ease of operation when needed while reducing power consumption during idle periods, directly resolving the technical contradiction between operational convenience and energy usage.
Solution Approach 2:
The system implements periodic monitoring where the wake-up module periodically checks for control signals from the remote controller. During idle periods, the RF transceiver enters sleeping mode with minimal power consumption, and is periodically woken up by the wake-up module to check for new signals, thus maintaining operational readiness while significantly reducing overall power consumption.
2Reliability
If the RF transceiver operates continuously to ensure real-time control capability, then the reliability is improved, but the duration of action decreases
Solution Approach 1:
The wake-up module is designed to detect control signals from the remote controller before the main RF transceiver needs to be fully activated. This preliminary detection action allows the system to prepare for incoming control commands without requiring the power-intensive RF transceiver to remain continuously active, thereby extending battery life while maintaining reliable control functionality.
Solution Approach 2:
The wake-up module serves as an intermediary between the remote controller and the main RF transceiver. It intercepts control signals first, validates them, and then activates the full RF transceiver system only when necessary. This intermediary approach ensures that the system remains reliable and responsive to control commands while dramatically reducing the duration of high-power operation, thus extending the battery's duration of action.

AI summary
A wireless signal transceiver device (100) including an RF transceiver (10), a microcontroller (20), and a wake-up module (30) is disclosed. Wherein, the microcontroller (20) is electrically connected to the RF transceiver (10), and the wake-up module (30) is electrically connected to the microcontroller (20). The power-saving control method for the wireless signal transceiver device (100) includes making the RF transceiver (10) to operate in the first sleeping mode, waiting to receive an RF wires signal, and determining whether there is a triggering signal included in the RF wireless signal or not; if not, returning to step B, and if yes, sending out a wake-up signal to the microcontroller (20) according to the triggering signal so as to enable the microcontroller (20) to control the RF transceiver (10) to change from the first sleeping mode to the first operation mode. Whereby, it is favorable to prevent the RF transceiver (10) from consuming electric power continuously so as to save power.
