Solution Overview

Problem

Mobile phones experience rapid temperature increases during batch updates of applications, leading to excessive heat and potential safety issues due to intense power consumption and concurrent application execution, which existing thermal mitigation methods do not adequately address.

Innovation Solution

A method for controlling terminal temperature by monitoring current temperature and adjusting the execution of tasks based on predefined temperature thresholds, suspending or delaying task execution when temperatures exceed safe levels, and dynamically adjusting the interval for temperature detection to manage heat emission effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If batch update of applications is performed, then application functionality is improved, but temperature of terminal rises rapidly

Engineering Contradiction:
Improveapplication update efficiencyVSAvoidterminal temperature
Core Design Contradiction:
ProductivityVSTemperature

Solution Approach 1:

The patent implements periodic temperature detection during batch updates, checking temperature at predetermined intervals. When temperature exceeds the threshold, the system suspends updates temporarily, then resumes after cooling, creating a periodic update-suspend-resume pattern that manages heat while maintaining productivity

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent dynamically adjusts the update process based on real-time temperature conditions. The system transitions between different operational states (normal update, suspension, resumption) depending on temperature thresholds, making the update process adaptive rather than static

Inventive Principle:
Principle #15Dynamics

2Speed

If multiple applications are updated concurrently, then update speed is improved, but power consumption increases intensely

Engineering Contradiction:
Improveupdate speedVSAvoidpower consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The patent segments the batch update process into multiple phases: initial temperature check, temperature monitoring during updates, suspension phase when threshold is exceeded, and resumption phase. This segmentation allows the system to manage power consumption by pausing intensive operations when necessary

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system continuously monitors temperature and uses this feedback to control the update process. When temperature exceeds the threshold, updates are suspended; when temperature drops below the threshold, updates resume. This feedback loop optimizes power usage while maintaining update progress

Inventive Principle:
Principle #23Feedback

3Measurement precision

If temperature detection interval is reduced, then temperature control precision is improved, but processing overhead increases

Engineering Contradiction:
Improvetemperature control precisionVSAvoidprocessing overhead
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent uses periodic temperature detection at predetermined intervals rather than continuous monitoring. This periodic approach provides sufficient temperature control precision while minimizing processing overhead by only checking temperature at specific intervals during the batch update process

Inventive Principle:
Principle #19Periodic action

AI summary

Embodiments of the present invention relate to a method for controlling temperature of a terminal, including: receiving, by the terminal, an instruction for triggering execution of a first task; obtaining, by the terminal, a current temperature of the terminal; and controlling, by the terminal, an execution manner of the first task based on the current temperature, to control temperature of the terminal. When the terminal obtains the current temperature of the terminal, the terminal may control, based on the current temperature of the terminal, the first task to be executed in different manners, so as to control temperature of the terminal and ensure that the mobile phone is in a safe state.
