Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed thermal management limits are used, then processor reliability is ensured, but performance optimization and design flexibility are restricted
Solution Approach 1:
The patent implements dynamic thermal management by allowing the processor to switch between multiple thermal modes (first thermal mode with first thermal limit, second thermal mode with second thermal limit) based on system conditions. This dynamic adjustment enables the system to adapt thermal limits to different operating scenarios, resolving the contradiction between fixed reliability and flexible adaptability.
Solution Approach 2:
The patent changes the thermal limit parameter from a fixed value to a configurable value that can be adjusted between different modes. By modifying the thermal limit parameter based on system properties and cooling capabilities, the system achieves both reliability (through defined thermal boundaries) and adaptability (through configurable limits).
2Productivity
If higher processing power is used, then performance increases, but heat generation and power consumption increase
Solution Approach 1:
The patent enables dynamic adjustment of thermal modes based on processing requirements and cooling capabilities. When higher processing power is needed, the system can switch to a thermal mode with appropriate thermal limits, allowing the processor to operate at higher performance levels while managing heat generation through configurable thermal boundaries.
Solution Approach 2:
The patent modifies thermal management parameters to match processing power requirements. By changing thermal limits and modes according to the processing workload, the system optimizes the balance between productivity (processing power) and energy loss (heat generation), allowing high performance when cooling capabilities permit.
3Loss of energy
If thermal limits are reduced, then power consumption decreases, but performance is limited
Solution Approach 1:
The patent implements dynamic thermal mode selection that allows the system to switch between different power consumption and performance levels based on system properties. When power consumption needs to be reduced, the system can select a thermal mode with lower thermal limits, and when performance is prioritized, it can switch to modes with higher thermal limits, resolving the contradiction between energy efficiency and productivity.
