Rotatable Power Delivery Module for Server Rack Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of interoperability between servers and different data center rack configurations, due to varying power delivery designs and busbar architectures, limits the flexibility and compatibility of IT equipment, increasing hardware costs and service complexities.
Innovation Solution
A rotational power delivery module with a rotatable power distribution board and clip module, allowing for dynamic adjustment to match different rack power architectures, ensuring proper connections and improving airflow and serviceability without requiring tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If servers are designed with fixed power delivery configurations to ensure proper function on specific rack types, then reliability is improved, but adaptability deteriorates
Solution Approach 1:
The power delivery module incorporates rotatable components including a rotatable power distribution board and a rotatable clip module that can rotate between first and second positions. This dynamic mechanism allows the same server design to adapt to different rack power architectures (e.g., rear busbar vs. front busbar configurations) while maintaining reliable power delivery connections appropriate for each configuration
2Adaptability or versatility
If multiple server designs are created to accommodate different rack specifications, then adaptability is improved, but device complexity increases
Solution Approach 1:
The power delivery module is designed as a universal component that can function with multiple rack types through its rotatable mechanism. The same server design with this module can be deployed across different rack specifications (OCP open racks, ODCC Scorpio racks, and others) without requiring multiple specialized server designs, thereby reducing overall system complexity while maintaining broad compatibility
3Reliability
If rigid power delivery connections are used to ensure stable power supply, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The rotatable clip module and power distribution board provide a dynamic connection system that maintains stable, reliable power connections when installed, while simultaneously enabling easy reconfiguration and relocation. The rotation mechanism allows operators to quickly adapt the power delivery module to different rack configurations without complex tools or procedures, combining connection stability with operational flexibility

AI summary
Embodiments are disclosed of a power delivery module that includes a power delivery board rotatable between a first orientation and a second orientation about a first axis that is normal to the power delivery board, and rotatable power clip module. Two pairs of electrical contacts are on the board: a first pair, one positive and one negative, and a second pair of electrical contacts, one positive and one negative. The two pairs of contacts are spaced apart from each other on the same side of the board. The rotatable power clip module is coupled to the power delivery board and includes a pair of contacts pads to engage with, and electrically couple to, the first or the second pairs of contacts. A power clip is electrically coupled to each contact pad. The clip module is rotatable about a second axis parallel to, and spaced apart from, the first axis between a first position, where the contact pads engage the first pair of contacts, and a second position where the contact pads engage the second pair of contacts.
