Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single PSU provides excessive power (>5KW) for intensive computational tasks, then the server can perform high-performance machine learning operations, but the PSU becomes unstable and prone to failure
Solution Approach 1:
The patent divides the single high-power PSU into multiple lower-power PSUs (e.g., two 3KW PSUs instead of one 6KW PSU). Each PSU operates within its stable power range, avoiding the instability that occurs when a single PSU is overloaded beyond its rated capacity. This segmentation allows the server to maintain high computational performance while improving overall system reliability.
2Power
If a single PSU operates at high power draw, then the server meets power demands for machine learning tasks, but heat generation overwhelms cooling solutions causing thermal throttling
Solution Approach 1:
By splitting the power delivery across multiple PSUs, the heat generation is distributed across multiple units rather than concentrated in a single PSU. This reduces the thermal load on each individual PSU and on the cooling system, preventing thermal throttling while maintaining the required total power delivery for machine learning workloads.
3Productivity
If a single PSU handles excessive power draw, then the server operates at high performance levels, but voltage regulation fluctuates causing system crashes
Solution Approach 1:
The patent segments the power conversion function across multiple independent PSUs, each with its own voltage regulation circuitry. This distributes the voltage regulation burden, preventing the fluctuations and instability that occur when a single PSU attempts to regulate excessive current alone. The result is stable voltage delivery that maintains system reliability at high performance levels.
4Power
If a single PSU is overloaded with high current draw, then the server executes intensive computational tasks, but overcurrent situations create safety hazards
Solution Approach 1:
The patent divides the high current draw requirement across multiple PSUs, each operating within its safe current output limits. This segmentation eliminates overcurrent situations that would create safety hazards such as electrical fires or component damage, while still delivering the total power needed for intensive computational tasks through the combined output of multiple PSUs.
