Solution Overview

Problem

Conventional electronic devices cannot adjust settings for new or updated application programs, affecting user experience due to unmanaged power consumption and temperature issues.

Innovation Solution

An electronic device with a processing unit, functional element, and control unit that determines the maximum frame count per second of a scene and dynamically tunes the frequency setting value of the core to manage power consumption and temperature, down-tuning when power consumption does not increase and temperature is below a preset value, and restoring when power consumption increases or temperature exceeds the preset value.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the frequency setting value of the core is increased to improve operating efficiency, then the processing speed and frame count per second improve, but the power consumption increases and the temperature of the functional element rises

Engineering Contradiction:

Improveframe count per secondVSAvoidtemperature of functional element

Core Design Contradiction:

ProductivityVSTemperature

Solution Approach 1:

The patent applies dynamics by making the frequency setting value adjustable rather than fixed. The control unit dynamically tunes the frequency setting value of the core based on real-time monitoring of power consumption and temperature, allowing the system to adapt between high performance and low power/temperature states as conditions change

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the frequency setting value parameter of the core to optimize system performance. By adjusting this parameter based on monitored conditions, the system can operate at higher frequencies when cooling is effective and at lower frequencies when temperature or power consumption concerns arise

Inventive Principle:

Principle #35Parameter changes

2Productivity

If the frequency setting value of the core is increased to improve operating efficiency, then the processing speed and frame count per second improve, but the power consumption of the processing unit increases

Engineering Contradiction:

Improveframe count per secondVSAvoidpower consumption of processing unit

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the frequency setting value based on real-time power consumption monitoring. When power consumption exceeds thresholds, the control unit down-tunes the frequency to reduce energy usage while maintaining acceptable performance levels

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The control unit implements feedback by continuously monitoring power consumption and temperature, then using this information to adjust the frequency setting value. This closed-loop control ensures the system operates efficiently within power constraints

Inventive Principle:

Principle #23Feedback

3Ease of operation

If preset performance settings are applied to common application programs at factory, then initial operating experience is improved, but the system cannot adapt to new or updated application programs

Engineering Contradiction:

Improveinitial operating experienceVSAvoidadaptability to new application programs

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system applies preliminary action by pre-configuring frequency setting values and performance parameters for common application programs at the factory. This provides immediate usability for standard applications while the adaptive tuning mechanism handles new or updated programs

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system transitions from static preset settings to dynamic adaptive tuning. The control unit continuously monitors performance and adjusts frequency settings in real-time, enabling the system to adapt to new application programs without requiring factory reconfiguration

Inventive Principle:

Principle #15Dynamics

AI summary

A power management method for an electronic device is provided. The electronic device includes a processing unit with a core and configured to execute an application program and a functional element. The power management method includes the following steps: determining a maximum frame count per second of a scene; down-tuning a frequency setting value of the core; detecting an actual frame count per second of the scene; determining a change in power consumption of the processing unit and a temperature of the functional element when the actual frame count per second is equal to the maximum frame count per second; and down-tuning the frequency setting value when the power consumption does not increase and the temperature is lower than a preset temperature value, and restoring the frequency setting value when the power consumption increases or the temperature is higher than or equal to the preset temperature value.
