Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Wearable devices face high power consumption due to processors remaining in a working state for low processing performance tasks, leading to reduced battery life.

Innovation Solution

Implementing a dual-core dual-system architecture with a low-power first processor and high-power second processor, allowing the first processor to draw and display the application interface while the second processor wakes up, reducing power consumption and delaying application screen display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the processor remains in a working state to handle low processing performance tasks, then the task execution reliability is improved, but the power consumption increases and battery life decreases

Engineering Contradiction:

Improvetask execution reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The processor is divided into two independent cores: a first core for high-power tasks and a second core for low-power tasks. This segmentation allows each core to operate independently based on task requirements, enabling the low-power core to handle simple tasks while the high-power core remains in sleep mode, thus reducing overall power consumption without compromising task execution reliability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically changes the operational parameters of processor cores by switching between wake and sleep states based on task complexity. When a low-processing-performance task is detected, the system activates only the low-power core and puts the high-power core to sleep, thereby adjusting power consumption parameters to match actual task requirements

Inventive Principle:

Principle #35Parameter changes

2Productivity

If the second processor wakes up to run the application, then the application performance is improved, but the screen display delay increases

Engineering Contradiction:

Improveapplication performanceVSAvoidscreen display delay

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The first processor pre-loads and prepares application data and resources while the second processor is still sleeping. When the second processor wakes up, the application can be launched immediately using the pre-prepared data, significantly reducing the screen display delay while maintaining high application performance

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The first processor acts as an intermediary that prepares application data in advance and transfers it to the second processor before the second processor fully wakes up. This intermediary action bridges the gap between the sleep state of the second processor and the need for immediate application execution, reducing perceived delay

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A method for displaying an application interface, a device, and a storage medium are provided. The method includes the following. An interface of a target application is drawn by a first system and displayed by the first system in response to an application start-up instruction of the target application when the first system is in a wake-up state and a second system is in a sleep state. The interface of the target application is drawn by the second system in response to the second system switching from the sleep state to the wake-up state. The interface of the target application is displayed by the second system, and the target application is run by the second system in response to the second system completing drawing the interface.
