Library Device Magazine Depth via Side-Mounted Backboards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing library device structure limits the depth of the magazine and the range of movement of the accessor mechanism, restricting the number of media that can be housed, especially in deep cell systems where media are stacked within a single cell.
Innovation Solution
The library device design allows the power supply and control devices to be connected along either side, with a shared backboard between them, enabling the magazine to be extended to the rear side and the accessor mechanism to move further, thereby increasing the depth and capacity for media storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the power supply device, control device, and drive device are disposed along the rear side and connected to a backboard, then the electrical connection and installation from the rear side is simplified, but the magazine depth and accessor mechanism movement range are limited
Solution Approach 1:
The patent changes the spatial arrangement from a rear-side linear layout to a side-side layout with perpendicular backboards. The power supply device and control device are disposed along one side connected to a first backboard, while the drive device is disposed along another side connected to a second backboard. This dimensional reorganization frees up rear space, enabling increased magazine depth and accessor mechanism movement range while maintaining electrical connection convenience.
2Reliability
If two separate backboards are used for the control device and drive device, then each device has dedicated connection, but the device complexity and space utilization increase
Solution Approach 1:
The patent merges the backboard structures by disposing the power supply device and control device along one side connected to a first backboard, and the drive device along another side connected to a second backboard. The backboards are electrically connected to each other, effectively creating an integrated electrical connection system. This merging approach maintains reliable electrical connections for all devices while reducing structural complexity and improving space utilization compared to completely separate backboard arrangements.

AI summary
Disclosed is a library device in which the space to enlarge the magazine can be secured to the rear side of the library device. The library device includes power supply means for supplying electricity to the library device, medium housing means which can house a plurality of computer-readable media, medium reading/writing means for reading/writing data from/to the medium, medium conveying means for conveying the medium between the medium housing means and the medium reading/writing means, control means for controlling operation of the library device and first connection means to which the power supply means and the control means can be electrically connected when these means are installed and from which the power supply means and the control means can be disconnected when these means are extracted. The power supply means, the first connection means, and the control means are disposed along any one of two sides of the library device, and one of the first connection means is disposed between the power supply means and the control means and whereby, the first connection means is connected to the power supply means and the control means.
