Terminal Thermal Throttling With Sensor-Based Frequency Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals face heat management challenges due to increased internal component density, leading to potential malfunctions and damage from high temperatures, especially in high ambient conditions, as the reduced space for heat dissipation makes it difficult to efficiently emit heat during high loads or high-speed operations.
Innovation Solution
A method involving a controller that adjusts its driving frequency based on temperature readings from a temperature sensor, implementing multi-stage throttle settings to reduce the terminal's temperature while maintaining performance, and restricting non-essential application programs to manage heat dissipation effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the density of internal components is increased to minimize terminal thickness and maximize screen area, then the terminal achieves better portability and display performance, but the space available for heat dissipation is reduced making heat emission difficult
Solution Approach 1:
The patent implements dynamic frequency adjustment of the processor based on real-time temperature monitoring. When temperature exceeds thresholds, the processor frequency is reduced or operations are suspended, creating a dynamic response system that adapts to thermal conditions rather than using static thermal management approaches
Solution Approach 2:
The system employs continuous temperature sensing with feedback control mechanisms. Temperature sensors monitor internal component temperatures and feed this information back to the controller, which then adjusts processor operations accordingly, forming a closed-loop thermal management system
2Productivity
If the terminal operates at high loads or high speed, then processing performance is improved, but heat accumulation in internal components increases beyond emission capacity
Solution Approach 1:
The processor operating frequency is dynamically adjusted based on temperature conditions. During high-load operations, when temperature rises, the system automatically reduces frequency or suspends operations to prevent excessive heat accumulation, creating a dynamic balance between performance and thermal management
Solution Approach 2:
The system changes operational parameters (processor frequency, operation suspension) in response to temperature changes. By modifying these parameters based on thermal conditions, the system prevents heat accumulation while maintaining optimal performance within safe temperature ranges
3Temperature
If the temperature of the terminal increases significantly, then heat emission is insufficient, but the terminal may malfunction or components may be damaged
Solution Approach 1:
The system performs preliminary temperature monitoring and takes preventive actions before damage occurs. By continuously monitoring temperature and implementing frequency reduction or operation suspension at predefined thresholds, the system prevents malfunctions and component damage before they can occur
Solution Approach 2:
Temperature feedback control mechanisms continuously monitor thermal conditions and adjust processor operations to maintain temperature within safe ranges, preventing the terminal from reaching temperatures that could cause malfunction or damage
4Temperature
If applications are terminated when temperature exceeds threshold, then temperature control is achieved, but system functionality is reduced
Solution Approach 1:
Instead of completely terminating all applications when temperature exceeds thresholds, the system applies partial action by selectively reducing processor frequency or suspending only specific non-essential operations. This approach achieves temperature control while preserving essential application functionality

AI summary
A method for controlling a temperature of a terminal and a terminal supporting the same are provided. A terminal supporting temperature control includes a temperature sensor for detecting a temperature of the terminal, and a controller for performing at least one of a first throttle procedure including driving the controller with a first preset driving frequency when the temperature of the terminal detected by the temperature sensor is a first preset temperature, and driving the controller with a second driving frequency higher than the first driving frequency when the temperature of the terminal is reduced to a second preset temperature lower than the first preset temperature, and a second throttle procedure including driving the controller with the first preset driving frequency for a first time, and driving the controller with the second driving frequency higher than the first driving frequency for a second time after the first time elapses.
