Solution Overview

Problem

Existing temperature control methods for terminals fail to effectively manage heat dissipation and power consumption in real-time based on user interaction, leading to potential user discomfort and reduced device performance.

Innovation Solution

A temperature control method and apparatus that continuously monitor the terminal's temperature and user interface state, adjusting power consumption of components like the processor, screen, and charging module based on whether the user is interacting with the device, employing different strategies to maintain optimal temperature without interfering with usage, such as reducing screen and charging power during interaction and limiting processor power during non-interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If power consumption of components is limited to reduce temperature, then temperature control is improved, but device performance deteriorates

Engineering Contradiction:
Improveterminal temperatureVSAvoiddevice performance
Core Design Contradiction:
TemperatureVSProductivity

Solution Approach 1:

The patent implements dynamic temperature control by continuously monitoring terminal temperature and adjusting power consumption of components in real-time based on current temperature levels and user interaction states. The system transitions between different power management modes (first mode during user interaction, second mode during non-interaction) to dynamically balance temperature control and performance maintenance

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters of components based on temperature conditions and user interaction state. When temperature exceeds thresholds, the system modifies power consumption parameters selectively - reducing screen brightness, limiting charging power, or throttling processor performance - to bring temperature back within acceptable ranges while minimizing impact on overall device functionality

Inventive Principle:
Principle #35Parameter changes

2Temperature

If power consumption is reduced during user interaction, then temperature control is improved, but user experience deteriorates

Engineering Contradiction:
Improveterminal temperatureVSAvoiduser experience
Core Design Contradiction:
TemperatureVSEase of operation

Solution Approach 1:

The patent segments temperature control strategies based on user interaction state, identifying distinct scenarios (user interacting vs. user not interacting) and applying different power management policies to each. During user interaction, the system maintains higher performance levels while still managing temperature through selective component power reduction, whereas during non-interaction, more aggressive power limiting is applied

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system continuously monitors both temperature levels and user interaction state, using this feedback to adjust power consumption in real-time. The control mechanism detects when users are actively using the device and adapts power management accordingly, ensuring temperature control measures do not interfere with ongoing user activities while still achieving thermal management goals

Inventive Principle:
Principle #23Feedback

AI summary

The present disclosure provides a temperature control method and a temperature control apparatus. The method includes determining a current state of a user interface of a terminal if a current temperature value of the terminal reaches a predetermined threshold, in which the current state of the user interface includes an interacting state and a non-interacting state; and performing a corresponding temperature control on the terminal according to the current state of the user interface. The temperature control method according to embodiments of the present disclosure, may perform the temperature control on the terminal in combination with an actual usage situation of the terminal such that the usage may not be influenced to a greatest extent when the temperature control is performed, thereby largely improving a user experience.
