Bridge Devices Switching Modes for Wired-Wireless Link Energy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data transmission systems using bridge devices between wired and wireless links, such as Ethernet and Wi-Fi, face high energy consumption, especially when used for video data transmission, and existing power-saving techniques are not applicable in these scenarios, leading to inefficiencies and increased energy usage.
Innovation Solution
The system employs bridge devices that can switch between nominal, energy-saving, and stop modes based on link activity and traffic volume, with the first bridge device switching to stop mode upon deactivation of the wired link and to energy-saving mode upon disconnection from the wireless network or reduced traffic, and the second bridge device doing similarly, allowing for reduced power usage without compromising data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bridge devices are used to connect wired and wireless links for flexible installation, then installation ease is improved, but energy consumption increases
Solution Approach 1:
The bridge device dynamically adjusts its operating mode (nominal, energy-saving, or stop mode) based on real-time detection of link activity and traffic conditions. The system transitions between different operational states to optimize energy consumption while maintaining installation flexibility, with interfaces being activated or deactivated according to actual data transmission needs.
Solution Approach 2:
The system changes operational parameters by switching between different modes: nominal mode for full performance, energy-saving mode with reduced performance but lower consumption, and stop mode with deactivated wireless interface. This parameter adjustment allows the bridge device to adapt its energy consumption level to match actual usage requirements.
2Reliability
If bridge devices operate in nominal mode to ensure data transmission quality, then transmission reliability is improved, but energy consumption increases
Solution Approach 1:
The bridge device dynamically switches between nominal and energy-saving modes based on detected traffic conditions. When bidirectional traffic volume exceeds a threshold, the system transitions to nominal mode to ensure transmission quality. When traffic is low or links are inactive, it switches to energy-saving mode with reduced performance, thus balancing reliability and energy consumption.
Solution Approach 2:
The system continuously monitors link activity and traffic volume, using this feedback to determine the appropriate operating mode. Detection mechanisms track data transmission patterns and adjust the bridge device's operational state accordingly, ensuring nominal mode is used only when necessary for maintaining transmission quality.
3Speed
If bridge devices are kept active to respond quickly to data transmission needs, then response speed is improved, but energy consumption increases
Solution Approach 1:
The bridge device performs preliminary detection of link activity and traffic conditions to anticipate when full operational capability will be needed. By monitoring traffic patterns and link status in advance, the system can transition modes proactively, ensuring nominal mode is activated before heavy transmission demands arise, thus maintaining response speed while avoiding prolonged high-energy operation.

AI summary
A first bridge device, connected by a first wired link to a supplying device, and a second bridge device, connected by a second wired link to a consuming device, are interconnected via a wireless communication network and are able to be configured in: a nominal operating mode; an energy saving mode; or a stop mode. The first bridge device switches into stop mode following detection of deactivation of the first wired link, and switches into energy saving mode following detection of disconnection from the network of the second bridge device or when the second bridge device goes into energy saving mode or following detection of a low volume of bidirectional traffic. The second bridge device switches into stop mode following detection of deactivation of the second wired link, and switches into energy saving mode following detection of the consuming device being put into hibernation or following detection of disconnection of the network or detection of a low volume of bidirectional traffic.
