Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server designs face challenges in interoperability due to varying rack configurations, including differences in form factor, power delivery design, and cooling methods, which limits their compatibility and functionality across different types of racks, increasing hardware costs and complexity for relocation and migration.
Innovation Solution
A rotatable power delivery module with a power delivery board and clip module that can adjust to different busbar architectures by rotating 180 degrees, ensuring proper positive and negative connections, and includes safety features to prevent improper connections, allowing seamless integration across diverse rack types without requiring tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If servers are designed to be compatible with multiple rack specifications, then interoperability is improved, but device complexity increases
Solution Approach 1:
The power delivery board is made rotatable about a first axis, allowing it to dynamically change orientation between a first orientation and a second orientation. This dynamic adjustment enables the same server design to adapt to different rack power delivery configurations without requiring multiple specialized designs, thereby improving interoperability while maintaining manageable complexity through a single adjustable component rather than multiple fixed designs.
2Adaptability or versatility
If power delivery board is made rotatable to adapt to different rack configurations, then adaptability is improved, but device complexity increases
Solution Approach 1:
The power delivery board incorporates rotational capability about a first axis, enabling it to switch between different orientations to match various rack power delivery designs. This single dynamic feature provides adaptability to multiple configurations without requiring entirely separate power delivery systems for each rack type.
Solution Approach 2:
The power delivery board is designed to perform multiple functions by rotating to different orientations, effectively serving as a universal power delivery component that can interface with various rack specifications. This multi-functionality reduces the need for multiple specialized components.
3Ease of operation
If clip module is rotatable to engage different electrical contacts, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The clip module is designed to rotate about a second axis that is parallel to and spaced apart from the first axis, allowing the power clips to engage different pairs of electrical contacts (first pair or second pair) depending on the orientation. This rotational capability enables easy engagement with different rack configurations through a simple rotational motion rather than requiring complex reconfiguration mechanisms.

AI summary
A power delivery module includes a power delivery board rotatable about a first axis between a first orientation and a second orientation. A first pair of contacts, one positive and one negative, is on a first side of the board, and a second pair of contacts, one positive and one negative, is on a second side of the board. The second positive contact is directly opposite the first negative contact and the second negative contact is directly opposite the first positive contact. A clip module is coupled to the board and includes a pair of power clips to engage with and electrically couple to the first or the second pairs of contacts. The clip module is rotatable about a second axis between a first position where the power clips engage the first pair of contacts and a second position where the power clips engage the second pair of contacts.
