Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The introduction of latches in tape libraries to securely retain magnetic tape cartridges has increased the time required to access and retrieve cartridges, reducing the number of exchanges per hour and increasing wear on retrieval mechanisms.

Innovation Solution

A media library system with a picker system that includes a first picker finger, a second picker finger, and a latch deactivator integrated with the first picker finger, allowing simultaneous movement of the latch from an activated to a deactivated position as the picker fingers engage the cartridge, facilitating efficient retrieval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If latches are introduced to securely retain media cartridges within storage slots, then cartridge security and retention are improved, but the time required to access and retrieve cartridges increases

Engineering Contradiction:

Improvecartridge retention securityVSAvoidcartridge access time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The latch deactivator is integrated with the picker finger to form a unified component. When the picker finger moves to engage the cartridge, the integrated latch deactivator simultaneously deactivates the latch, combining two separate actions (latch deactivation and cartridge engagement) into one motion, thereby reducing access time while maintaining secure retention

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If latches are introduced to securely retain media cartridges, then cartridge security is improved, but the number of exchanges per hour decreases

Engineering Contradiction:

Improvecartridge retention securityVSAvoidexchanges per hour

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

By integrating the latch deactivator with the picker finger, the system performs latch deactivation and cartridge retrieval in a single coordinated motion, eliminating separate latch-release steps and thereby increasing the number of exchanges per hour while maintaining secure retention

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If latches are introduced to securely retain media cartridges, then cartridge security is improved, but wear on retrieval mechanisms increases

Engineering Contradiction:

Improvecartridge retention securityVSAvoidmechanical wear on retrieval mechanisms

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The integrated design allows the picker finger to deactivate the latch through its normal engagement motion, eliminating the need for separate latch-release mechanisms and reducing mechanical wear on retrieval components while maintaining secure cartridge retention

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A media library includes a media cartridge, a storage slot that selectively receives and retains the media cartridge, and a picker system. The storage slot includes a latch configured to securely retain the media cartridge within the storage slot. The picker system is configured to selectively retrieve the media cartridge from within the storage slot. The picker system includes a first picker finger, an opposed second picker finger, and a latch deactivator configured to selectively move the latch from an activated position in which the latch inhibits the media cartridge from being removed from the storage slot, to a deactivated position in which the latch does not inhibit the media cartridge from being removed from the storage slot. The latch deactivator is coupled to the first picker finger such that movement of the first picker finger results in corresponding movement of the latch deactivator.
