Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power supplying methods for servers, particularly those with GPU configurations, suffer from low efficiency due to the use of a 54 V power supply combined with a 12 V conversion module, leading to increased costs, power consumption, and difficulty in maintenance when the conversion module is damaged.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a 54 V power supply combined with a 12 V conversion module is used, then GPU configurations can be powered, but the overall power supplying efficiency is low and power consumption is increased
Solution Approach 1:
The patent divides the power supply system into separate 12 V and 54 V power supply units, each independently supplying power to different components. The 12 V PSU supplies power to CPU, memory, and storage, while the 54 V PSU supplies power to GPU, eliminating the need for voltage conversion and improving overall efficiency.
Solution Approach 2:
The patent introduces a power management controller as an intermediary to coordinate between the 12 V and 54 V power supply units. This controller manages the power distribution, ensures proper power-on sequences, and prevents voltage conflicts, enabling efficient hybrid power supply operation.
2Adaptability or versatility
If a 54 V power supply combined with a 12 V conversion module is used, then GPU configurations can be powered, but the system complexity increases and maintenance difficulty increases
Solution Approach 1:
The patent separates the power supply system into independent modular units (12 V PSU and 54 V PSU), each with dedicated conversion modules. This segmentation reduces system complexity by eliminating the need for a single complex conversion system and enables independent maintenance of each module.
Solution Approach 2:
The patent extracts the voltage conversion function from the motherboard and integrates it into dedicated power supply units. This extraction simplifies the motherboard design and allows the conversion modules to be maintained or replaced independently without affecting the rest of the system.
3Productivity
If simultaneous power-on of 12 V and 54 V power supplies is allowed, then both components can start at the same time, but voltage overshoot occurs
Solution Approach 1:
The patent implements a controlled power-on sequence where the 54 V power supply is activated first, followed by the 12 V power supply after a predetermined time interval. This preliminary sequencing prevents voltage overshoot by ensuring the higher voltage supply is stable before introducing the lower voltage supply.
Solution Approach 2:
The power management controller monitors the power-on status and voltage levels of both power supply units. Based on this feedback, the controller dynamically adjusts the power-on timing and enables/disables power supply outputs to prevent voltage conflicts and overshoot conditions.
4Reliability
If mechanical foolproof measures are added to prevent mixed insertion, then power supply reliability improves, but device complexity increases
Solution Approach 1:
The patent employs asymmetric mechanical designs where the 12 V and 54 V power supply connectors have different physical geometries (e.g., different pin configurations, connector shapes, or positioning features). This asymmetry ensures that only the correct power supply can be inserted into its designated slot, preventing mixed insertion through purely mechanical means without additional active control components.
