Solution Overview

Problem

Data storage libraries face issues with condensation formation due to temperature and humidity differentials between the interior and exterior environments, leading to potential component degradation and failure, especially when moving data storage cartridges between hot, humid data centers and cool, dry library environments.

Innovation Solution

A self-cooled data storage library with a media acclimation device that gradually adjusts the environmental conditions of data storage cartridges using a combination of thermoelectric heaters, coolers, heaters, coolers, air conditioners, and humidity control units to match the internal library conditions, preventing condensation and ensuring stable operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If environmental conditioning units are used to control temperature and humidity inside the data storage library, then the internal environment is stabilized for media protection, but condensation forms on cartridges during installation and removal due to temperature differential between interior and exterior environments

Engineering Contradiction:

Improvemedia protectionVSAvoidcondensation formation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The media acclimation device performs preliminary acclimation of cartridges by gradually adjusting their temperature and humidity conditions before they are installed into or removed from the library. This preliminary action prevents condensation from forming during the transition between environments.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The media acclimation device serves as an intermediary chamber between the controlled library environment and the external environment. Cartridges pass through this intermediate zone where environmental conditions are gradually adjusted, preventing direct exposure to temperature differentials that cause condensation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of energy

If data storage cartridges are moved between hot, humid data centers and cool, dry library environments, then operational costs are reduced by running equipment at high end environmental limits, but magnetic tape media degrades due to exposure to unfavorable conditions

Engineering Contradiction:

Improveoperational costsVSAvoidmedia degradation

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

Before cartridges are moved from the data center to the library, the media acclimation device preliminarily adjusts their environmental conditions to match the library's controlled environment. This prevents media degradation during the transition period.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The media acclimation device gradually changes the environmental parameters (temperature and humidity) of cartridges during the acclimation process. This controlled parameter change allows cartridges to adapt to new environmental conditions without experiencing shock that would cause media degradation.

Inventive Principle:

Principle #35Parameter changes
