Disc Device Tray with Corner Cutouts for Compact Magazine Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for higher data capacity in disc devices, driven by cloud computing, leads to a need for more magazines and discs, which in turn increases disc conveying time and device size, necessitating a solution to reduce both conveying time and device size.
Innovation Solution
A disc device design featuring a tray with cut portions at its corners, allowing it to rotate and shift before being fully drawn out, reducing contact with the case and minimizing the space required for extraction, thus decreasing conveying time and device size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of magazines and stored discs is increased to improve data capacity, then the data capacity is improved, but the disc conveying time increases and the device size increases
Solution Approach 1:
The tray is provided with cut portions at corner portions positioned on the back side of the case, which enables the tray to be rotated by the picker when the cut portions pass through the opening. This preliminary structural preparation allows the tray to change its extraction path and be drawn out more efficiently, reducing the disc conveying time even when the number of magazines and discs is increased.
2Quantity of substance
If the number of magazines and stored discs is increased to improve data capacity, then the data capacity is improved, but the device size increases
Solution Approach 1:
The cut portions are formed at the tray in advance, enabling the picker to rotate the tray during extraction when the cut portions pass through the opening. This preliminary structural feature allows the tray to be drawn out more efficiently, reducing the width dimension of the space required in front of the magazine, thereby suppressing device size increase even as data capacity increases.
3Ease of operation
If the tray is drawn out completely from the case without rotation, then the tray extraction is simple, but the disc conveying time increases and device size increases
Solution Approach 1:
The tray is designed with cut portions that enable dynamic rotation during the extraction process. When the picker draws out the tray, the cut portions pass through the opening and allow the tray to be rotated by the picker. This dynamic adjustment optimizes the extraction path and reduces disc conveying time while maintaining operational simplicity.
4Ease of operation
If the tray is drawn out completely from the case without rotation, then the tray extraction is simple, but the width dimension of the space in front of the magazine increases
Solution Approach 1:
The tray incorporates cut portions that enable dynamic rotation during extraction. As the picker draws out the tray, the cut portions pass through the opening and permit rotation, allowing the tray to be drawn out more efficiently. This reduces the width dimension of the space required in front of the magazine while maintaining the simplicity of the extraction operation.

AI summary
A disc device which takes out a disc stored in a magazine and conveys the disc to any disc drive, in which the magazine comprises a tray which stores a plurality of discs, and a case which has a substantially rectangular parallelepiped shape and which stores the tray. The case has an opening at front face into which the tray can be inserted into or taken out therefrom. The tray has an outer shape being substantially rectangular in planar view. The tray is provided with cut portions formed at corner portions positioned on the back side of the case being cut off. The disc device further comprises a picker which holds the tray and draws out the tray from the case. The picker rotates the tray when the cut portion passes through the opening.
