Network Node Power Mode Transition via Energy Pattern Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In energy-conscious and response-time-conscious environments, such as automotive communication networks, there is a challenge in balancing energy efficiency and quick response times, particularly due to the time required to transition from reduced-power modes, which can degrade user experience in electric vehicles.
Innovation Solution
A technique involving a device with a physical interface and circuitry that detects energy patterns in a communication channel, waits for a predefined time, and then transitions to an increased-power mode upon recognizing a specific pattern, allowing for concurrent power mode transitions across network nodes to maintain response times while reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If network nodes transition to reduced-power modes to reduce energy consumption, then energy efficiency is improved, but response time deteriorates due to transition delays
Solution Approach 1:
The system performs preliminary actions by detecting energy patterns and predicting upcoming communication activities before they occur. When energy patterns indicate likely future communication, the network node proactively transitions to increased-power mode in advance, ensuring immediate responsiveness while only consuming higher power when actually needed. This predictive approach resolves the contradiction by preparing the system beforehand rather than reacting after transition delays occur.
Solution Approach 2:
The network node autonomously monitors its own energy consumption patterns and makes intelligent decisions about power mode transitions without external control. The system serves itself by detecting energy patterns, predicting communication needs, and autonomously transitioning between power modes to optimize both energy efficiency and response time. This self-service capability enables the node to dynamically balance the contradiction between power savings and response performance based on real-time conditions.
2Loss of time
If network nodes remain in increased-power mode to ensure quick response times, then response time is improved, but energy consumption increases
Solution Approach 1:
Instead of continuously remaining in increased-power mode, the system implements periodic monitoring of energy patterns and uses this information to periodically transition between power modes. The node periodically assesses energy consumption patterns, predicts future communication needs, and transitions to increased-power mode only during periods when communication is anticipated. This periodic approach replaces continuous high-power operation with intermittent high-power states, significantly reducing overall energy consumption while maintaining quick response times when needed.
3Device complexity
If network nodes use traditional energy detection methods, then detection simplicity is maintained, but accuracy deteriorates in electrically noisy environments
Solution Approach 1:
The system introduces an intermediary layer between raw energy detection and decision-making. Instead of directly using simple energy detection results, the system uses energy patterns as intermediary data that feeds into a prediction mechanism. The energy patterns serve as intermediate representations that capture meaningful information about future communication while filtering out noise. This intermediary approach maintains the simplicity of energy detection while improving accuracy by using the detected patterns to predict actual communication events rather than reacting to every detected energy fluctuation.
