Solution Overview

Problem

Current electronic devices consume excessive resources and current when updating multiple applications, as they update the output of both updated and non-updated applications, leading to inefficient resource utilization.

Innovation Solution

The electronic device selectively updates only the output of actually updated applications by identifying and managing the display areas of updated and non-updated applications, optimizing resource allocation and reducing unnecessary updates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the electronic device updates the output of all displayed applications, then the display is always current, but current consumption and resource use increase

Engineering Contradiction:

Improvedisplay currencyVSAvoidcurrent consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent extracts only the updated application outputs from the complete set of displayed applications. The display controller identifies which applications have been updated and selectively updates only those specific outputs, rather than refreshing all application outputs. This extraction principle reduces unnecessary processing and current consumption while maintaining display currency for actually changed content.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies partial action by performing updates only on the subset of applications that have actually been updated, rather than executing full updates on all displayed applications. The display controller determines which applications require updates and processes only those, avoiding excessive action on non-updated applications and thereby reducing current consumption and resource utilization.

Inventive Principle:

Principle #16Partial or excessive action

2Reliability

If the electronic device updates all application outputs, then no display is missed, but resource utilization becomes inefficient

Engineering Contradiction:

Improvedisplay completenessVSAvoidresource utilization efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent extracts and processes only the updated application outputs from the complete set of displayed applications. The display controller identifies which applications have been updated and selectively updates only those specific outputs, rather than refreshing all application outputs. This extraction principle reduces unnecessary processing and current consumption while maintaining display currency for actually changed content.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Inventive Principle:

Principle #16Partial or excessive action

3Speed

If the electronic device processes multiple application updates simultaneously, then all updates are applied quickly, but current consumption increases

Engineering Contradiction:

Improveupdate processing speedVSAvoidcurrent consumption

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The patent segments the update processing into distinct groups: updated applications and non-updated applications. The display controller divides the processing workload by identifying which applications have been updated and processing only those segments. This segmentation allows the system to maintain processing speed for necessary updates while avoiding energy consumption from processing unnecessary updates.

Inventive Principle:

Principle #1Segmentation
