Solution Overview

Problem

Information handling systems often fail to operate effectively in extreme temperature environments, particularly when temperatures drop below the specified minimum, leading to functional failures or damage, as they require pre-heating before initialization.

Innovation Solution

A pre-heater device with a data storage drive form-factor is integrated into the information handling system, featuring a power connector and optionally a data connector, compliant with standards like SATA, which pre-heats the system by activating a fan and heating element assembly to maintain temperatures within operational specifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the information handling system operates in low-temperature environments, then the system can be deployed in extreme conditions, but the system fails to operate effectively and may suffer functional failures or damage

Engineering Contradiction:

Improveoperational temperature rangeVSAvoidsystem operational reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The pre-heater device activates before the information handling system initialization to raise the internal temperature to an acceptable operating range. This preliminary heating action ensures that when the system initializes, all components are already at appropriate temperatures, preventing operational failures and extending the system's effective operating environment.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If a pre-heater device is added to the information handling system, then the system can operate in low-temperature environments, but the device complexity increases

Engineering Contradiction:

Improveoperational temperature rangeVSAvoidsystem component count

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pre-heater device is designed with a data storage drive form-factor and interfaces using standard connectors (e.g., SATA power connector), allowing it to utilize existing system infrastructure and mounting mechanisms. This multi-functionality approach enables the pre-heater to be integrated without requiring dedicated complex mounting structures, thereby minimizing the increase in overall system complexity while achieving extended temperature adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Temperature

If the pre-heater activates the heating element assembly, then the temperature increases to operational levels, but energy consumption increases

Engineering Contradiction:

Improveinternal system temperatureVSAvoidpre-heater power consumption

Core Design Contradiction:

TemperatureVSUse of energy by moving object

Solution Approach 1:

The pre-heater operates periodically rather than continuously, activating the heating element assembly only during the pre-heating phase before system initialization. Once the target temperature is reached, the pre-heater shuts off, allowing the system's normal operation to maintain temperature. This periodic operation significantly reduces overall energy consumption compared to continuous heating, while still achieving the necessary temperature increase for reliable operation in low-temperature environments.

Inventive Principle:

Principle #19Periodic action
