Host Signal Processing Frequency Switching for Low-Power Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Host devices are unable to enter low power modes due to frequent data exchange with external devices, leading to high power consumption and failure to meet energy-saving requirements.
Innovation Solution
Switching the processing frequency of the host device from a higher first frequency to a lower second frequency in response to a power consumption mode switching request, and optionally disconnecting the connection with the external device to reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the host device maintains high processing frequency for frequent data exchange with external devices, then data exchange functionality is ensured, but power consumption increases and the device cannot enter low power mode
Solution Approach 1:
The patent applies dynamics by making the processing frequency adjustable rather than fixed. The host device dynamically switches between first processing mode (high frequency) and second processing mode (low frequency) based on connection status. When connected to external devices, the device operates at first frequency to ensure reliable data exchange. When disconnected, it switches to second frequency to reduce power consumption, thus adapting the system behavior to changing conditions.
Solution Approach 2:
The patent changes the processing frequency parameter based on connection status. By switching between first frequency (higher) and second frequency (lower), the system optimizes the balance between data exchange reliability and power consumption. This parameter change allows the device to enter low power mode when external devices are disconnected while maintaining full functionality when connected.
2Reliability
If the host device operates at high processing frequency to handle frequent data exchange, then communication reliability is maintained, but the device cannot automatically enter sleep or energy saving mode
Solution Approach 1:
The system dynamically adjusts processing mode based on real-time connection status detected through heartbeat signals. When no heartbeat signal is received indicating disconnection, the device automatically transitions from first processing mode to second processing mode, enabling automatic entry into low power state without manual intervention while maintaining communication reliability when connected.
Solution Approach 2:
The patent uses heartbeat signals as feedback mechanism to monitor connection status. The host device receives periodic heartbeat signals from external devices and uses this feedback to determine whether to maintain high processing frequency or switch to low processing frequency. This feedback-driven approach enables automatic power mode switching while ensuring communication reliability when devices are connected.

AI summary
A processing method comprising, based on an power consumption mode switching request of a first device, switching the first device from a first processing mode to a second processing mode, and in response to the power consumption mode switching request, switching a power consumption mode of the first device from a first mode to a second mode. In the first processing mode, a processing frequency of the first device for a signal received from a second device is a first frequency. In the second processing mode, the processing frequency of the first device for the signal received from the second device is a second frequency. The second frequency is lower than the first frequency. The second mode has lower power consumption than the first mode.
