Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing power saving modes in broadband devices often interrupt internet sessions during brief power outages and are less effective than conventional UPS systems during 'power flapping' scenarios, leading to reduced usability and battery inefficiency.

Innovation Solution

Implementing an intelligent power saving mode that includes user-defined power policies and environmental information from external sources, allowing for a delay to enter and exit power saving mode, thereby minimizing disruptions during short power outages and extending battery life during longer outages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If the broadband device enters power saving mode immediately when power is lost, then battery life is extended, but internet sessions are interrupted during brief power outages

Engineering Contradiction:

Improvebattery lifeVSAvoidinternet session continuity

Core Design Contradiction:

Duration of action of moving objectVSReliability

Solution Approach 1:

The patent implements dynamic power management by introducing configurable delay parameters (enter_delay and exit_delay) that allow the device to adapt its power saving behavior based on the duration of power outages. The system dynamically determines whether to enter power saving mode by comparing the actual power loss duration against the configured delay threshold, thereby optimizing the balance between battery conservation and service continuity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of the power saving mode by introducing time delay configurations. Instead of immediately entering or exiting power saving mode, the system uses configurable delay parameters to control the transition timing. This parameter adjustment allows the device to tolerate brief power fluctuations while still achieving battery savings during extended outages.

2Reliability

If the broadband device uses conventional UPS to maintain power during outages, then internet sessions are preserved, but battery power is depleted faster during lengthy outages

Engineering Contradiction:

Improveinternet session continuityVSAvoidbattery power consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically switches between different operational states (normal mode and power saving mode) based on the duration of power outages. By configuring appropriate delay thresholds, the system remains in normal mode during brief outages to maintain session continuity, then transitions to power saving mode for extended outages to conserve battery power, optimizing the trade-off between reliability and energy consumption.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements preliminary configuration of delay parameters (enter_delay and exit_delay) that pre-establish the conditions for mode transitions. These pre-configured parameters enable the system to automatically make optimal decisions without real-time user intervention, balancing session continuity and battery conservation based on anticipated outage scenarios.

3Duration of action of moving object

If the broadband device implements power saving mode during power outages, then battery life is extended, but the device becomes less usable during power flapping scenarios

Engineering Contradiction:

Core Design Contradiction:

Duration of action of moving objectVSEase of operation

Solution Approach 1:

The system uses dynamic delay-based logic to determine power mode transitions, making the device adaptable to different power outage scenarios. By configuring the enter_delay and exit_delay parameters, the system automatically adjusts its behavior to maintain usability during power flapping while still achieving battery savings during prolonged outages, resolving the contradiction between battery life extension and ease of operation.
