Solution Overview
Problem
Electronic devices face performance limitations due to excessive heat generation, which can degrade components and reduce user service quality, as existing methods to manage heat often compromise system performance or degrade user experience.
Innovation Solution
An electronic device equipped with a temperature sensor and processor that detects excessive temperatures and adaptively controls background processes by driving them for a proportion of time periods and not driving them during remaining periods, thereby managing heat generation without degrading user service quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If many functions are performed with limited resources, then the functionality and performance of the electronic device are improved, but heat generation increases and components may degrade
Solution Approach 1:
The system dynamically adjusts process execution based on real-time temperature conditions. When temperature exceeds the threshold, the processor selectively stops or reduces execution of certain processes, creating a dynamic adaptation mechanism that balances functionality with thermal management
Solution Approach 2:
The system changes operational parameters by monitoring temperature and adjusting process execution states. The processor modifies the execution state of processes (from full execution to partial or stopped execution) based on temperature parameter changes, thereby controlling heat generation while maintaining essential functionality
2Reliability
If background processes are continuously executed to maintain service quality, then user service quality is improved, but heat generation increases
Solution Approach 1:
The system implements periodic temperature monitoring and conditional process execution. Instead of continuous process execution, the processor periodically checks temperature conditions and adjusts process execution accordingly, creating a rhythm of execution and suspension that manages heat while maintaining service quality when conditions permit
3Temperature
If the processor stops processes to reduce heat generation, then temperature control is improved, but system performance and user service quality may degrade
Solution Approach 1:
The system applies selective process management where different processes are treated differently based on their importance and thermal characteristics. Critical processes maintaining user service quality continue to execute, while non-critical processes are stopped or reduced, creating localized quality differences in process execution that balance temperature control with performance
