Solution Overview

Problem

Existing electronic devices lack a user-centric approach to power saving functions, as they do not account for the type of application running and user's task duration, leading to inconsistent battery life predictions and inefficient power management.

Innovation Solution

An electronic device that determines power usage state, estimates available time, and prompts user input for power saving options, including adjusting screen brightness and resource allocation based on application type and task duration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the electronic device provides power saving functions by deactivating hardware or software functions, then power consumption is reduced, but user convenience and task completion capability deteriorate

Engineering Contradiction:

Improvepower consumptionVSAvoiduser convenience

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The system dynamically adjusts power saving measures based on real-time conditions. It monitors task type, remaining time, and power consumption rate to determine the appropriate power saving mode, transitioning between different operational states rather than using a fixed power saving setting

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters based on task characteristics. For time-critical tasks, it maintains higher performance parameters; for non-critical tasks, it reduces parameters to save power. The power saving strategy is adjusted by changing parameters like CPU frequency, screen brightness, and network activity based on the identified task type and remaining time

Inventive Principle:

Principle #35Parameter changes

2Use of energy by moving object

If the electronic device provides general power saving functions, then power consumption is reduced, but adaptability to different application types and user scenarios deteriorates

Engineering Contradiction:

Improvepower consumptionVSAvoidadaptability to application type

Core Design Contradiction:

Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The system segments tasks into different categories (time-critical, non-time-critical, background) and applies different power saving strategies to each segment. This allows tailored power management for different application types and usage scenarios rather than a one-size-fits-all approach

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary analysis of the running task to identify its characteristics and requirements before applying power saving measures. By predicting the task type and remaining time in advance, it can pre-determine the appropriate power saving strategy, ensuring adaptability to different application types

Inventive Principle:

Principle #10Preliminary action

3Use of energy by moving object

If the electronic device provides power saving functions without user interaction, then power consumption is reduced, but user awareness and control over power usage deteriorate

Engineering Contradiction:

Improvepower consumptionVSAvoiduser awareness

Core Design Contradiction:

Use of energy by moving objectVSLoss of information

Solution Approach 1:

The system provides feedback to the user about power consumption status, task completion progress, and available power saving options. It displays information about the predicted time to complete tasks and allows users to review and adjust power saving decisions, maintaining user awareness and control

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system automatically manages power consumption by selecting and executing power saving measures without requiring explicit user commands. It autonomously monitors task progress and power usage, making decisions about when and how to apply power saving functions while still informing the user

Inventive Principle:

Principle #25Self-service
