Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the system frequency is decreased to lower the temperature of the device, then the temperature control is improved, but the system performance deteriorates excessively
Solution Approach 1:
The patent changes the control parameter from simple temperature-based frequency reduction to a composite parameter considering both temperature and workload status. The control circuit adjusts frequency based on temperature detection results combined with workload information, allowing for more nuanced parameter adjustment that maintains performance while controlling temperature.
Solution Approach 2:
The patent implements dynamic frequency adjustment based on real-time temperature and workload conditions. Instead of static frequency reduction, the system continuously monitors both temperature and workload status, dynamically adjusting the frequency divider circuit to achieve optimal balance between thermal management and performance requirements.
2Temperature
If the system frequency is excessively reduced to control temperature, then the temperature management is improved, but the device functionality is compromised
Solution Approach 1:
The patent introduces composite parameter control that combines temperature data with workload status information. This allows the system to distinguish between high temperature caused by heavy workload versus other factors, adjusting frequency appropriately to maintain functionality while managing temperature.
Solution Approach 2:
The patent implements a feedback mechanism where the control circuit receives both temperature detection results and workload status information, processes this feedback information, and adjusts the frequency divider circuit accordingly. This closed-loop control ensures that frequency adjustment decisions are based on comprehensive system state information, preventing excessive reduction that would compromise functionality.
