Innovation Solution

A monitoring system analyzes historical utilization data to forecast network device usage and selectively enables or disables non-forwarding components based on a power management plan, optimizing power consumption without disrupting traffic flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If network device components remain enabled to ensure availability, then reliability is improved, but energy consumption increases

Engineering Contradiction:
Improvenetwork device availabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic power management by transitioning network device components between enabled and disabled states based on real-time utilization monitoring. The system adjusts component states dynamically rather than maintaining static enabled/disabled configurations, allowing the network device to adapt its power consumption to actual traffic conditions while maintaining availability when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the operational state parameter of network components based on utilization thresholds. When utilization falls below a threshold, components are transitioned to a disabled low-power state; when utilization exceeds the threshold, components are re-enabled. This parameter change approach allows the system to optimize power consumption while maintaining reliability through threshold-based state transitions.

Inventive Principle:
Principle #35Parameter changes

2Loss of energy

If components are disabled to reduce power consumption, then energy efficiency is improved, but service continuity may be disrupted

Engineering Contradiction:
Improveenergy efficiencyVSAvoidservice continuity
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the system continuously monitors network utilization and adjusts component states accordingly. When utilization exceeds a threshold, the system receives feedback that traffic is increasing and re-enables components to maintain service continuity. This closed-loop feedback ensures that power management decisions do not disrupt service while achieving energy efficiency during low-utilization periods.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary actions by enabling components before traffic spikes occur and disabling them after traffic subsides. The threshold-based approach allows the system to anticipate utilization patterns and take preliminary power management actions that maintain service continuity while optimizing energy efficiency. Components are re-enabled in advance when thresholds are approached, preventing service disruption.

Inventive Principle:
Principle #10Preliminary action
