Flexible PSU Bay Adaptor for Redundant Power Supply Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Power Distribution Board (PDB) or its board retention structure often cannot withstand the insertion force of redundant Power Supply Units (PSUs), leading to incomplete insertion and deformation, which results in connectivity issues and reliability problems in Information Handling Systems (IHS) data centers.
Innovation Solution
A flexible Power Supply Unit (PSU) bay is designed with a PSU adaptor that includes a tab and stopper to resist movement and deformation during the insertion of redundant PSUs, and a mechanism that moves downward to accommodate cabled PSUs, providing electrical insulation and ensuring proper engagement with the PSU cage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid Power Distribution Board (PDB) retention structure is used to support redundant PSUs, then structural strength is improved, but the PDB cannot accommodate different PSU types (cabled and redundant) and may deform under insertion force
Solution Approach 1:
The patent applies the dynamics principle by making the PDB retention structure flexible rather than rigid. The PDB is designed to bend and deform elastically during PSU insertion, allowing it to accommodate different PSU types (cabled and redundant) while maintaining structural integrity. This dynamic behavior enables the same structure to adapt to various insertion forces and PSU configurations without deformation or failure.
2Reliability
If the PDB is designed to withstand high insertion force for redundant PSUs, then insertion reliability is improved, but cabled PSUs cannot be properly installed as the PDB does not move downward
Solution Approach 1:
The patent applies parameter changes by allowing the PDB retention structure to change its physical state during insertion. The PDB transitions from a rigid state during normal operation to a flexible state during insertion, enabling it to move downward when force is applied. This parameter change allows the same structure to provide both high insertion reliability (by withstanding force) and ease of operation (by moving downward to accommodate cabled PSUs).

AI summary
Systems and methods for a flexible Power Supply Unit (PSU) bay are described. In some embodiments, a chassis may include a surface and a PSU adaptor disposed on the surface, the PSU adaptor comprising a tab having a stopper coupled thereto, where the stopper is configured to: (a) resist movement, bending, or deformation of a board perpendicularly disposed with respect to the surface upon insertion of a first PSU into a PSU cage, and (b) move downward upon insertion of a second PSU into the PSU cage.
