Rack-Mounted Power Switch Manipulator for Tight Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased demand for computing resources and storage in storage racks leads to reduced space for operators to access and manipulate power switches, making it difficult to physically reach and see the switches, especially when the space between rear pillars is occupied by cabling and other components.
Innovation Solution
A power switch manipulation apparatus with a base member secured to the storage rack and a tool that can fit through tight spaces, featuring a guide channel for rotation and translation, allowing users to manipulate power switches without physically reaching into the rack, using a handle to operate the tool from outside the rack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the interior space of storage racks is increased by adding more FRUs, cabling, and components, then the computing resources and storage capacity are improved, but the space available for operators to access and manipulate power switches is reduced
Solution Approach 1:
A manipulation apparatus with a tool and guide channel acts as an intermediary between the operator and the power switch. The operator manipulates the tool from outside the rack, and the guide channel transmits this manipulation to the power switch located deep within the rack, eliminating the need for direct hand insertion into the crowded interior space.
Solution Approach 2:
The manipulation apparatus extends the operational interface from the three-dimensional interior space to the two-dimensional exterior face of the rack. By providing a guide channel that protrudes from the rack front, the system allows operators to access switches that would otherwise require penetration into the depth of the rack interior.
2Quantity of substance
If the space between rear pillars and rear opening is occupied by cabling and components, then the computing resources are improved, but the ability to physically reach and see power switches is reduced
Solution Approach 1:
The manipulation apparatus serves as a mediator that bridges the gap created by obstructing cabling and components. The guide channel provides a dedicated pathway through the obstruction to the power switch, and the tool extends the operator's reach without requiring direct line-of-sight or physical access to the switch location.
Solution Approach 2:
The guide channel is pre-positioned and secured to the rack structure before operation. This preliminary arrangement creates a fixed pathway that guides the tool precisely to the power switch location, eliminating the need for operators to navigate around cabling and components during the switching operation.
3Ease of operation
If a tool is designed to fit through tight spaces between rear pillars and power switches, then the accessibility is improved, but the tool complexity increases
Solution Approach 1:
The manipulation apparatus is divided into distinct segments: a base member that interfaces with the rack structure, a guide channel that provides the pathway, and a tool that performs the switching operation. This segmentation allows each component to be optimized independently while maintaining overall simplicity.
Solution Approach 2:
The guide channel serves multiple functions: it guides the tool to the correct position, provides structural support, and defines the operational pathway. By combining these functions into a single component, the overall device complexity is reduced despite the tight space constraints.

AI summary
Power switch manipulation apparatuses that allow users to manipulate power switches of FRUs mounted within storage racks in a manner free of a user having to physically reach into the storage rack to manipulate the power switches. One embodiment of the disclosed manipulation apparatus broadly includes a base member that may be rigidly secured to a portion of the frame of a storage rack (e.g., on a side or vertical member adjacent a rear door or opening of the rack at the same or similar height as at least one of the power switches) along with a tool that is movably mounted or mountable to the base member for manipulating a power switch of a FRU mounted in the rack.
