Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current solutions fail to effectively optimize energy consumption in web application environments, particularly where widgets and event-based applications run continuously in the background, leading to battery drain issues in mobile devices.

Innovation Solution

A method that detects events triggering web resources, estimates energy consumption, compares it to a predetermined budget, and adjusts priorities to conserve energy by pausing or stopping lower-priority activities, while providing user notifications and options to manage energy usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If web applications and widgets run continuously in the background to provide elaborate functionality, then user experience and service availability are improved, but energy consumption increases and battery longevity deteriorates

Engineering Contradiction:

Improveweb application functionalityVSAvoidenergy consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the operation state of web application components based on energy budget constraints. Event handlers are selectively activated or deactivated depending on current energy availability, allowing the application to adapt its functionality dynamically rather than running all components continuously

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements partial action by allowing only certain event handlers to execute based on energy budget availability. When energy budget is exceeded, lower-priority event handlers are prevented from executing, while critical handlers continue to function, providing essential functionality with reduced energy consumption

Inventive Principle:

Principle #16Partial or excessive action

2Adaptability or versatility

If multiple applications and threads run simultaneously to enhance device capabilities, then functionality is improved, but energy consumption increases and battery life decreases

Engineering Contradiction:

Improvedevice functionalityVSAvoidbattery longevity

Core Design Contradiction:

Adaptability or versatilityVSDuration of action of stationary object

Solution Approach 1:

The system performs preliminary energy budget allocation before executing multiple applications and threads. Energy budgets are pre-calculated and assigned to different applications based on their priority and expected energy consumption, preventing excessive energy usage before it occurs

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors energy consumption of running applications and provides feedback to the resource manager. When energy budget thresholds are approached or exceeded, the system adjusts application execution accordingly, creating a closed-loop control system that balances functionality with battery longevity

Inventive Principle:

Principle #23Feedback

3Ease of operation

If event-based web applications are allowed to run freely, then user interaction responsiveness is improved, but energy consumption increases and operational control deteriorates

Engineering Contradiction:

Improveuser interaction responsivenessVSAvoidenergy consumption

Core Design Contradiction:

Ease of operationVSUse of energy by stationary object

Solution Approach 1:

The system segments event handlers into different priority levels and energy budget categories. Critical user interaction handlers are separated from non-essential handlers, allowing the system to guarantee energy allocation for essential interactions while limiting or disabling non-essential ones when energy budget is constrained

Inventive Principle:

Principle #1Segmentation
