Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increase in power consumption and temperature in electronic devices leads to throttling functions that reduce performance, and existing systems lack effective methods to manage heat generation variably across multiple devices, risking system failure due to temperature rises in individual components.
Innovation Solution
A heat management circuit with temperature sensors and an analysis unit that monitors and throttles operations based on temperature thresholds, identifies abnormal temperature sensors, and determines the cause of heat generation, distinguishing between internal and external issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If throttling function is adopted to maintain or lower temperature, then temperature control is improved, but performance is reduced
Solution Approach 1:
The system dynamically adjusts the throttling state based on real-time temperature monitoring. The processor transitions between throttled and non-throttled states according to whether temperature thresholds are exceeded, allowing performance to be maximized when safe and reduced only when necessary for thermal management
Solution Approach 2:
The system implements a feedback mechanism where temperature sensors continuously monitor thermal conditions and provide information to the control logic. This feedback loop enables the system to make informed decisions about when to apply or remove throttling, optimizing the balance between temperature control and performance maintenance
2Temperature
If throttling is applied to individual electronic devices, then local temperature management is improved, but system-wide reliability deteriorates due to potential system stoppage
Solution Approach 1:
The system divides thermal management into independent per-device zones, allowing each electronic device to be throttled individually based on its own temperature conditions. This segmentation ensures that thermal issues in one device do not propagate to affect the entire system, maintaining system-wide reliability while managing local temperature problems
Solution Approach 2:
The system applies differentiated thermal management policies to different devices based on their specific thermal conditions. Each device receives customized throttling control appropriate to its local temperature state, rather than applying uniform system-wide throttling, thus preserving overall system functionality while addressing local thermal issues
3Temperature
If cooling is performed for predetermined time, then temperature reduction is achieved, but time delay in performance restoration occurs
Solution Approach 1:
The system implements periodic temperature monitoring and conditional throttling rather than continuous or fixed-duration cooling. Throttling is applied in periods only when temperature thresholds are exceeded, and removed immediately when thresholds are satisfied, minimizing unnecessary time delays while ensuring adequate temperature management
Solution Approach 2:
The system proactively removes throttling as soon as temperature conditions satisfy the threshold criteria, rather than maintaining fixed cooling durations. This preliminary action to restore performance immediately when safe minimizes time delays while preventing premature thermal issues
