Adjustable PSU Bracket for Variable Open-Frame Power Supply Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in accommodating open frame power supply units (PSUs) of varying dimensions and shapes within a chassis of electronic equipment without requiring costly modifications or customizations of the chassis.
Innovation Solution
An adjustable PSU bracket is designed to enclose the open frame PSU, allowing for size adjustments to fit different PSU widths and heights. The bracket consists of movable sections and foot mounts that can be coupled to the chassis, enabling easy installation and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard chassis is used to house open frame PSUs of varying dimensions, then the chassis structure remains simple and cost-effective, but the adaptability to accommodate different PSU sizes and shapes is insufficient
Solution Approach 1:
The bracket incorporates movable sections that can slide relative to each other along guide rails, allowing the bracket to dynamically adjust its dimensions to match different PSU sizes. This dynamic adjustment capability enables a single bracket design to accommodate multiple PSU configurations without requiring chassis modifications.
Solution Approach 2:
The bracket is divided into multiple separable sections including a first bracket section, a second bracket section, and foot mounts that can be independently adjusted. This segmentation allows each component to be positioned and sized independently to fit the specific dimensions of the installed PSU, providing versatility while maintaining a relatively simple overall structure.
2Adaptability or versatility
If custom tooling or modified chassis are used to accommodate specific PSU types, then the compatibility with that specific PSU is improved, but the manufacturing cost and complexity increase significantly
Solution Approach 1:
The bracket is designed as a universal mounting solution that can accommodate multiple types and sizes of open frame PSUs through its adjustable mechanism. Rather than creating custom tooling for each PSU type, the single universal bracket design provides multi-functionality, reducing manufacturing costs and simplifying the production process while maintaining compatibility with various PSU specifications.
3Ease of operation
If fixed-size brackets are used for mounting PSUs, then the bracket design is simple, but the ease of installation for different PSU sizes is reduced
Solution Approach 1:
The bracket employs movable sections with locking mechanisms that allow installers to easily adjust the bracket size to match the PSU dimensions before securing it in place. The dynamic adjustment capability simplifies the installation process for different PSU sizes while the locking mechanism ensures the bracket remains stable during operation, balancing ease of installation with operational reliability.

AI summary
An adjustable bracket for enclosing an open frame power supply unit (PSU) is disclosed. The adjustable bracket includes a first bracket section having a first primary plate and a first secondary plate extending generally vertically from one end of the first primary plate; and a second bracket section having a second primary plate and a second secondary plate extending generally vertically from one end of the second primary plate, the first secondary plate and the second secondary plate being generally parallel such that the first secondary plate faces the second secondary plate. The second primary plate is movably coupled to the first primary plate such that the adjustable bracket can be in a compact, intermediately extended, or fully extended configuration by adjusting the bracket according to a width of the open frame PSU, the width being different for a first open frame PSU than for a second open frame PSU.
