Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If thermal throttling is applied to reduce power consumption, then power efficiency improves, but device performance deteriorates
Solution Approach 1:
The patent implements dynamic thermal throttling that adjusts the degree of performance limitation based on real-time thermal conditions and host device requirements. The memory device transitions between different operational states (normal operation, thermal throttling, and heavy thermal throttling) based on temperature thresholds, allowing optimal balance between power consumption and performance under varying conditions.
Solution Approach 2:
The patent changes operational parameters (throttling degree) based on thermal conditions and host requirements. By adjusting the throttling level from none to light to heavy, the system modifies its performance characteristics to match current power needs while maintaining acceptable performance levels.
2Adaptability or versatility
If fixed thermal throttling mechanism is used, then device complexity is reduced, but adaptability to different host requirements deteriorates
Solution Approach 1:
The patent incorporates feedback mechanisms where the memory device monitors its own thermal state and receives information about host device requirements. This feedback loop enables the device to automatically adjust its operational mode, selecting from different thermal throttling configurations based on current conditions and host preferences.
Solution Approach 2:
The system transitions from static thermal throttling to dynamic adaptive throttling, where the throttling behavior changes in real-time based on thermal conditions and host device configuration. This allows the same hardware to serve multiple application scenarios with different performance-power tradeoff requirements.
