Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of memories and operation rates are increased to achieve higher integration and performance, then system performance is improved, but heat generation increases causing thermal degradation and potential component failure
Solution Approach 1:
The patent implements a feedback mechanism where temperature information is continuously monitored by a temperature information acquisition unit and fed back to a control unit. When the temperature exceeds a threshold, the control unit adjusts system parameters (such as operation rates or workload distribution) to reduce heat generation, thereby maintaining system performance while preventing thermal degradation
Solution Approach 2:
The system dynamically changes operational parameters based on temperature conditions. The control unit modifies operation rates, memory access patterns, or component activation states in response to temperature feedback, allowing the system to adapt its performance characteristics to thermal conditions and prevent overheating while maintaining optimal productivity
2Productivity
If the physical distance between heat-emitting components is shortened to increase integration, then system integration is improved, but heat concentration increases causing thermal degradation
Solution Approach 1:
The patent divides the system into multiple independently controllable components or modules. The control unit can selectively adjust the operation of individual components based on their local temperature conditions, allowing heat management at a granular level. This segmentation enables the system to maintain high integration while managing heat concentration in specific areas through targeted parameter adjustments
3Reliability
If continuous temperature monitoring is implemented to prevent thermal degradation, then reliability is improved, but system complexity increases
Solution Approach 1:
The system incorporates self-monitoring capabilities where components automatically detect and report their own temperature conditions. The temperature information acquisition unit is integrated into the existing system architecture, allowing components to self-assess their thermal state without requiring external monitoring infrastructure, thereby improving reliability while minimizing added complexity

AI summary
A system includes: a master device; and a slave device including a temperature variation measuring circuit for measuring a temperature variation amount of the salve device for a predetermined time. The slave device transfers temperature information to a master device when a temperature variation amount for the predetermined time is equal to or greater than a threshold value, the temperature information representing that the temperature variation amount for the predetermined time is equal to or greater than the threshold value. The master device determines a temperature of the slave device in response to the temperature information, and controls the slave device based on the determined temperature of the slave device.
