Modular Power Supply Bus for Flexible Server Wattage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power supply modules in servers have fixed specifications, limiting flexibility in accessory selection and increasing manufacturing costs due to mismatched power requirements, as higher or lower wattage modules necessitate removal or addition of accessories.
Innovation Solution
A power supply bus apparatus with a modular design featuring a first and second power supply backplane, docking structures, and an electrical bus insertion group with different polarities, allowing for flexible connection of power supply modules of varying wattages without wires, facilitating easy maintenance and reduced wind resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed specification power supply modules are used, then manufacturing cost is reduced, but flexibility in accessory selection is limited
Solution Approach 1:
The power supply system is segmented into modular components: a standardized backplane and interchangeable power supply modules with different wattages. This segmentation allows the server to be configured with different power modules based on accessory requirements without redesigning the entire power supply system, thus improving flexibility while maintaining manufacturing efficiency through standardized interfaces.
Solution Approach 2:
The backplane is designed with universal docking structures that can accommodate multiple types of power supply modules (different wattages). This multi-functionality allows a single backplane design to support various power requirements, enabling flexible accessory selection without increasing manufacturing complexity for the base structure.
2Adaptability or versatility
If high-wattage power supply modules are used, then high-order accessories can be supported, but manufacturing cost increases
Solution Approach 1:
The power supply configuration is made dynamic and adjustable rather than fixed. Users can change power supply modules based on the actual power requirements of installed accessories, allowing the system to adapt to different configurations. This dynamic approach enables support for high-order accessories when needed while avoiding the cost of always having high-wattage modules installed.
Solution Approach 2:
The power capacity parameter of the power supply module can be changed by swapping modules rather than being fixed in the design. This parameter change capability allows the system to match power supply capacity to actual load requirements, supporting high-order accessories when required while optimizing manufacturing costs by using lower-wattage modules for configurations that don't require them.
3Reliability
If wire-based power connection is used, then electrical connection is stable, but wind resistance increases and heat dissipation is reduced
Solution Approach 1:
The traditional wire-based mechanical electrical connection is replaced with a contactless docking structure using electromagnetic fields. This substitution eliminates physical wires that create wind resistance and heat accumulation, while maintaining stable electrical connection through the docking interface between the backplane and power supply module.
