Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Large-screen terminals often experience lag when exiting split-screen display mode due to high system resource usage by animations, which hinders smooth transitions between application windows.

Innovation Solution

A method that adjusts animation information to reduce system resource occupancy by optimizing animation duration and effects, allowing for efficient switching from a current window to a new window with reduced resource consumption, thereby avoiding lag during the transition process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If animation effects are used during split-screen exit transition, then transition smoothness is improved, but system resource usage increases causing lag

Engineering Contradiction:

Improvetransition smoothnessVSAvoidsystem resource usage

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent dynamically adjusts animation parameters (duration, complexity, resource allocation) based on real-time system resource availability and processor frequency, allowing the animation to adapt its resource consumption while maintaining smooth transition effects

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes animation parameters such as duration, complexity level, and resource allocation dynamically during the transition process, adjusting these parameters based on system resource monitoring to balance smoothness with resource efficiency

Inventive Principle:

Principle #35Parameter changes

2Speed

If processor frequency is increased during window switching, then switching speed is improved, but power consumption increases

Engineering Contradiction:

Improveswitching speedVSAvoidpower consumption

Core Design Contradiction:

SpeedVSUse of energy by stationary object

Solution Approach 1:

The patent implements periodic processor frequency adjustment, temporarily increasing frequency during the critical window switching phase and then reducing it to normal levels after the transition completes, creating a periodic high-performance pulse that balances speed with power savings

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent performs preliminary frequency adjustment and resource allocation before the actual window switching occurs, preparing the system in advance to execute the transition quickly and then immediately returning to lower power state

Inventive Principle:

Principle #10Preliminary action
