Static Widget Rendering for Lower Memory and Power Use

Solution Overview

Problem

Electronic devices with numerous widget subcomponents experience increased memory occupation and power consumption due to continuous running and refreshing of these components, leading to inefficient resource usage.

Innovation Solution

A widget display method that renders a plurality of components into a static image, reducing the need for continuous component refresh and rendering, thereby minimizing memory usage and power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple subcomponents are continuously rendered and refreshed in a widget, then the widget functionality and interaction are maintained, but memory occupation and power consumption increase

Engineering Contradiction:

Improvewidget functionalityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic rendering by capturing widget components at specific intervals (e.g., when data changes) rather than continuous rendering. The captured components are stored as images and displayed until the next capture event, creating a periodic action pattern that reduces power consumption while maintaining widget functionality.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent creates image copies of widget components instead of continuously rendering the actual components. These image copies (bitmaps) are stored in memory and displayed in place of the original components, reducing the computational overhead and power consumption associated with continuous component rendering and refreshing.

Inventive Principle:

Principle #26Copying

2Reliability

If multiple subcomponents are continuously rendered and refreshed in a widget, then the widget functionality and interaction are maintained, but memory occupation increases

Engineering Contradiction:

Improvewidget functionalityVSAvoidmemory occupation

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent creates image copies of widget components instead of continuously rendering the actual components. These image copies (bitmaps) are stored in memory and displayed in place of the original components, reducing the computational overhead and power consumption associated with continuous component rendering and refreshing.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent implements periodic rendering by capturing widget components at specific intervals (e.g., when data changes) rather than continuous rendering. The captured components are stored as images and displayed until the next capture event, creating a periodic action pattern that reduces power consumption while maintaining widget functionality.

Inventive Principle:

Principle #19Periodic action

3Use of energy by moving object

If a static image is used to replace multiple rendered components, then memory usage and power consumption are reduced, but interaction functionality must be preserved

Engineering Contradiction:

Improvepower consumptionVSAvoidinteraction functionality

Core Design Contradiction:

Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The patent segments the widget into multiple independent components, each with its own image capture and interaction handling. Each component can be independently rendered, captured as an image, and have its interaction areas defined separately, allowing the static image to maintain full interaction functionality while reducing power consumption.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces interaction area definitions as an intermediary layer between the static image display and the underlying component functionality. By defining specific areas in the static image that correspond to interactive elements, the system preserves touch and click functionality without requiring continuous rendering of the actual components.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A widget display method includes receiving a first trigger operation of a user, where the first trigger operation is used to add a first static widget, and the first static widget corresponds to a plurality of components. The widget display method further includes rendering the plurality of components corresponding to the first static widget, and generating and displaying a first static image based on the plurality of rendered components, where the first static image is used to display first resource content corresponding to the first static widget.
