Server Tray Mechanism for Hard Disk Cable Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The arrangement of hard disks in servers is restricted by the location of connection ports on the back shell, limiting space utilization and making it difficult to efficiently use the available space within the server.
Innovation Solution
The server design incorporates multiple trays with U-shaped containers and a chain mechanism that allows hard disk modules to be easily pulled out and pushed back in, enabling cables to connect to either front or rear ports, improving space utilization and facilitating maintenance by allowing multiple trays to be independently accessed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If connection ports are positioned on the back shell of the server, then cable connectivity is achieved, but space utilization is restricted and hard disk arrangement is limited
Solution Approach 1:
The server storage system is segmented into multiple independent trays that can be individually accessed and positioned. Each tray contains hard disk modules with their own connection ports, allowing independent arrangement and removal without affecting other storage units. This segmentation enables flexible space utilization while maintaining connectivity.
Solution Approach 2:
The connection architecture transitions from a single back-shell connection point to multiple connection ports distributed across different spatial dimensions. Each tray has its own connection ports that can interface with connection points along the sides or front of the server, creating a three-dimensional connection network that enables flexible hard disk arrangement throughout the available space.
2Quantity of substance
If multiple hard disks are arranged in the server, then storage capacity increases, but maintenance difficulty increases due to restricted access
Solution Approach 1:
The storage system is divided into multiple independent trays, each containing one or more hard disk modules. This segmentation allows individual trays to be removed from the server for maintenance without requiring access to all hard disks. The modular design enables technicians to quickly isolate and service specific storage units while leaving other trays in place.
Solution Approach 2:
The trays are pre-configured with integrated cable management and connection mechanisms that prepare the system for easy maintenance. Cables are routed through the tray structure itself, and connection ports are positioned to allow quick disconnection. This preliminary arrangement of connections and access paths enables rapid maintenance operations.
3Ease of operation
If trays are made removable for maintenance, then accessibility improves, but structural integrity and appearance may be compromised
Solution Approach 1:
The tray system incorporates dynamic locking mechanisms that allow trays to be securely fixed in operational positions while enabling easy removal when needed. The locking system transitions between locked and unlocked states based on operational requirements, providing both structural integrity during normal operation and accessibility during maintenance. The trays can be smoothly inserted and locked into place, maintaining stability when installed.

AI summary
A server containing hard disk modules which can be slid into place and which allow connection at the front and at the rear of a housing. The server includes the housing which defines an opening, the hard disk modules, and a plurality of trays. Receiving channels communicating with the opening are defined in the housing, the receiving channels are isolated and arranged side by side and each channel can receive one tray. A hard disk module is positioned in one tray, a front end and a rear end of the housing defines front connection port and rear connection port for cable connections to each hard disk module.
