Disc Storage Rack Shutter Mechanism for Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disc trays in data center storage systems are prone to popping out due to vibrations such as earthquakes, posing a risk to data security and requiring more robust prevention mechanisms than simple elastic claws, especially given their heavier weight compared to magnetic tape cartridges.
Innovation Solution
A disc storage device rack with a guided sliding operation and a slidable shutter mechanism on each side plate to securely accommodate and retrieve disc trays, preventing them from popping out during vibrations, and a transport robot for managing disc trays within the rack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple elastic claw mechanism is used to prevent disc tray pop-out, then the mechanism complexity is reduced, but the reliability of preventing pop-out during vibrations deteriorates due to the heavy weight of disc trays
Solution Approach 1:
The shutter is designed to be movable rather than fixed, capable of sliding between open and closed positions. During normal operation, the shutter remains open to allow tray access. During vibrations or earthquakes, the shutter automatically closes to prevent pop-out, providing dynamic adaptation to different operational states without requiring complex control systems
Solution Approach 2:
The rack structure is divided into separate modular components: side plates with guide portions, independently movable shutters for each accommodation space, and partition plates. This segmentation allows each shutter to independently respond to vibrations in its specific location, improving overall reliability while keeping individual components simple and manageable
2Ease of operation
If guide portions are provided on side plates to guide sliding operation, then the ease of operation for pulling out and pushing in disc trays is improved, but the device complexity increases due to additional structural components
Solution Approach 1:
The guide portions on the side plates work passively to guide the shutter and disc tray sliding operations. The structure serves itself by using the inherent geometry of the guide portions and grooves to automatically align and constrain movement, eliminating the need for additional active control mechanisms or complex guiding systems
Solution Approach 2:
The guide portions act as intermediaries between the side plates and the shutter/disc tray. They mediate the interaction by providing a predefined path and constraint, allowing smooth sliding operation while distributing mechanical stresses, thus improving ease of operation without significantly increasing overall structural complexity

AI summary
A disc storage device rack includes: an accommodation space surrounded by left and right side plates and upper and lower partition plates and configured to accommodate a disc storage device; a guide portion provided on the side plates and configured to fit to a guided unit provided in the disc storage device to guide a sliding operation of the disc storage device; and a shutter provided on each end surface of the side plates so as to be slidable in an up-and-down direction and configured to open an opening of the guide portion when the disc storage device is pulled out from the accommodation space or when the disc storage device is pushed into the accommodation space.
