Solution Overview

Problem

Computing devices face challenges in maintaining hardware components within thermal operating limits when thermal management systems are inoperable, leading to potential failures and service disruptions.

Innovation Solution

A data processing system proactively elevates hardware component temperatures before thermal management becomes unavailable, using a management controller to identify elevated goal temperatures and warm zones to these levels, then disables heating during updates to ensure components remain within operational ranges.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If heating is disabled during thermal management unavailability, then component safety is improved, but temperature maintenance capability deteriorates

Engineering Contradiction:

Improvecomponent safetyVSAvoidtemperature maintenance capability

Core Design Contradiction:

ReliabilityVSTemperature

Solution Approach 1:

The system proactively elevates hardware component temperatures to elevated goal temperatures before thermal management becomes unavailable. This preliminary heating action ensures that when heating is subsequently disabled during management unavailability, the components remain within operational temperature ranges for the duration of the unavailability period.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system establishes a thermal cushion by heating components to elevated temperatures before thermal management unavailability occurs. This thermal cushion acts as a buffer that allows components to maintain acceptable operating temperatures even when active heating is disabled during the unavailability period, thus cushioning against the potential harmful effect of temperature drop.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Temperature

If heating is enabled during thermal management unavailability, then temperature maintenance is improved, but system reliability deteriorates

Engineering Contradiction:

Improvetemperature maintenanceVSAvoidsystem reliability

Core Design Contradiction:

TemperatureVSReliability

Solution Approach 1:

Instead of relying on continuous heating during unavailability, the system performs preliminary heating to elevated temperatures before unavailability begins. This eliminates the need for active heating control during the unavailability period, thereby maintaining system reliability while still achieving temperature maintenance through the pre-established thermal cushion.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If components are heated to elevated temperatures, then operational continuity during unavailability is improved, but energy consumption increases

Engineering Contradiction:

Improveoperational continuityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system concentrates energy consumption into a preliminary heating phase before thermal management unavailability, rather than requiring continuous energy input during the unavailability period. The elevated goal temperatures are set to provide sufficient thermal cushion for the specific duration of expected unavailability, optimizing the balance between operational continuity and energy consumption.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements periodic temperature monitoring and adjusts heating cycles to maintain elevated temperatures only when necessary. During thermal management availability, the system heats to elevated levels; during unavailability, it maintains temperatures without active heating control, creating a periodic pattern that reduces overall energy consumption compared to continuous heating.

Inventive Principle:

Principle #19Periodic action

AI summary

Methods and systems for managing the operation of data processing systems are disclosed. A data processing system may include a computing device that may provide computer implemented services. To provide the computer implemented services, hardware components of the data processing system may need to operate in predetermined manners. To manage the operation of the hardware components, the data processing system may heat them when their temperatures fall outside of thermal operating ranges. To manage the hardware components when heating is unavailable, the data processing system may proactively heat them to elevated goal temperature ahead of periods of time when heating is unavailable.
