Disk With Separation Protrusion And Groove For Stacked Magazine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional disk devices face challenges in increasing the number of disks stored due to disk sticking issues and inefficient conveyance times, with existing solutions requiring complex and costly mechanisms for separating stacked disks.
Innovation Solution
A disk design featuring a central hole with a supportable structure that allows separation claws to project from the outer diameter, enabling easy separation and support of stacked disks without interfering with adjacent disks, thereby reducing conveyance time and increasing storage capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If disks are directly stacked without trays to increase storage capacity, then the number of disks contained increases, but the disks adjacent to each other stick to each other making separation difficult
Solution Approach 1:
The invention divides the disk into multiple parts by adding a separation protrusion and separation groove structure. The separation protrusion on one disk fits into the separation groove of the adjacent disk, creating a mechanical interface that prevents sticking and enables easy separation while maintaining the stacked configuration.
Solution Approach 2:
The separation protrusion and groove act as an intermediary mechanical feature between adjacent disks. This intermediary structure provides a controlled interface that prevents direct contact and adhesion between disk surfaces, allowing separation claws to engage and separate the disks without difficulty.
2Quantity of substance
If the number of magazines is increased to store more disks, then storage capacity increases, but the distance between the farthest magazine and disk drive increases, increasing conveyance time
Solution Approach 1:
The invention merges multiple disk storage locations into a single magazine by enabling direct stacking of multiple disks within one magazine. The separation protrusion and groove structure allows multiple disks to be stored in a compact stacked arrangement, eliminating the need for multiple separate magazines and reducing conveyance distance.
Solution Approach 2:
The invention utilizes the vertical dimension by stacking disks vertically within the magazine using the separation protrusion and groove interface. This vertical stacking approach increases storage capacity within the same horizontal footprint and reduces the need for additional magazines positioned at greater distances from the disk drive.
3Ease of operation
If substrate separating claws are made thin to fit in the gap between disks, then they can separate disks, but they lack sufficient strength and may deform during use
Solution Approach 1:
The separation interface is segmented into a protrusion on one disk and a corresponding groove on the adjacent disk. This segmentation allows the separation claw to engage with the protrusion-groove interface rather than attempting to fit in a narrow gap, providing sufficient leverage and strength while maintaining the ability to separate disks.
4Ease of operation
If high positioning accuracy is required for the ejection arm to insert separation claws into gaps between ribs, then disk separation is possible, but the mechanism becomes expensive
Solution Approach 1:
The disk structure is segmented with separation protrusions and grooves that create a mechanical interface. This segmentation eliminates the need for high-precision positioning by providing a self-aligning interface where the protrusion fits into the groove, allowing the separation claw to engage without requiring the ejection arm to position with high accuracy between narrow gaps.
