Cable Management Arm with Elastic Reset for Rack Chassis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rack systems require complex cable management mechanisms to maintain smooth movement of power and signal cables during server or storage maintenance, necessitating two separate movement mechanisms to manage cables from both left and right controllers.
Innovation Solution
A cable management arm system comprising left and right cable management assemblies, a connection assembly, and an elastic assembly that moves with the chassis, ensuring cables are managed and reset horizontally when the chassis is pulled out, using U-shaped grooves and pivot connections for efficient cable management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate movement mechanisms are designed to manage cables from left and right controllers, then cable management capability is improved, but device complexity increases
Solution Approach 1:
The patent merges the left and right cable management assemblies into a single integrated structure that shares common components including the connection assembly, elastic assembly, and guiding mechanisms. This integration maintains the ability to manage cables from both controllers while reducing the overall number of independent mechanisms and simplifying the system architecture.
2Device complexity
If cable management assemblies are integrated and share common components, then device complexity is reduced, but reliability may worsen due to shared failure points
Solution Approach 1:
While integrating common components, the patent maintains independent functional segments for left and right cable management. Each side has its own cable management groove and guiding groove bodies that can operate independently, ensuring that a failure in one side does not necessarily affect the other side's cable management functionality.
3Ease of operation
If elastic assembly is used to enable movement and reset, then ease of operation is improved, but manufacturing precision requirements worsen
Solution Approach 1:
The patent employs an elastic assembly that provides dynamic, flexible connection between the cable management assemblies and the rack. This elastic connection allows for automatic adjustment and reset during chassis insertion and removal, accommodating manufacturing tolerances and reducing the need for extremely precise manufacturing while maintaining smooth operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively manages cables from both controllers, ensuring they move horizontally and reset properly, simplifying maintenance by integrating elastic members for smooth movement and secure connection to the rack and chassis.
Implementation Method 1
The elastic assembly is connected with the connection assembly, the left cable management assembly, and the right cable management assembly, respectively. When a chassis in the rack is pulled out of the rack, the elastic assembly causes the left cable management assembly and the right cable management assembly to move following the movement of the controller at the rear of the chassis in the pulling out direction, and causes the left cable management assembly and the right cable management assembly to reset due to elastic force.
Data Source
AI summary
The present disclosure provides a cable management arm and a rack applying the cable management arm. The cable management arm includes: a left cable management assembly, a right cable management assembly, a connection assembly, and an elastic assembly. When a chassis in the rack is pulled out of the rack, the elastic assembly causes the left cable management assembly and the right cable management assembly to move following the movement of the controller at the rear of the chassis in the pulling out direction, and causes the left cable management assembly and the right cable management assembly to reset due to elastic force. The connection assembly and the elastic assembly assist the movement of the left cable management assembly and the right cable management assembly to cause their resetting, and ensure them to move in an approximately horizontal space.
