Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If HVAC systems are designed to handle multiple computing devices, then cooling coverage is improved, but thermal distribution uniformity deteriorates due to hot spots and cold spots

Engineering Contradiction:

Improvecooling coverage areaVSAvoidthermal distribution uniformity

Core Design Contradiction:

Area of stationary objectVSTemperature

Solution Approach 1:

The patent implements dynamic workload migration that moves computing processes in real-time based on thermal conditions. This dynamic adjustment allows the system to adapt to changing thermal patterns without requiring physical HVAC reconfiguration, effectively balancing thermal distribution while maintaining comprehensive cooling coverage

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system applies local quality by making thermal management decisions at the individual device level. Each computing device's workload is independently evaluated and migrated based on its specific thermal environment, allowing targeted thermal management that addresses hot spots locally while maintaining overall system balance

Inventive Principle:

Principle #3Local quality

2Temperature

If HVAC resources are redistributed to meet changing thermal demands, then thermal balance is improved, but system complexity and implementation difficulty increase

Engineering Contradiction:

Improvethermal balanceVSAvoidHVAC reconfiguration complexity

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

The patent replaces mechanical HVAC reconfiguration with software-based workload migration. Instead of physically moving or reconfiguring HVAC components, the system uses virtualization and software control to migrate computing workloads, achieving thermal balance through information processing rather than mechanical manipulation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system implements self-service thermal management where the computing infrastructure automatically monitors its own thermal conditions and autonomously migrates workloads to maintain thermal balance. This eliminates the need for external HVAC intervention and reduces system complexity by making the thermal management self-regulating

Inventive Principle:

Principle #25Self-service

3Temperature

If computing applications are moved to balance thermal distribution, then thermal characteristics are improved, but service continuity deteriorates due to potential interruptions

Engineering Contradiction:

Improvethermal distributionVSAvoidservice continuity

Core Design Contradiction:

TemperatureVSReliability

Solution Approach 1:

The patent ensures continuity of useful action by implementing seamless workload migration that maintains service availability throughout the migration process. The virtualization infrastructure allows computing processes to be moved between physical devices without interrupting the delivered service, ensuring continuous operation while achieving thermal balance

Inventive Principle:

Principle #20Continuity of useful action

4Temperature

If static HVAC design is used for computer rooms, then initial thermal management is improved, but adaptability to changing equipment performance deteriorates

Engineering Contradiction:

Core Design Contradiction:

TemperatureVSAdaptability or versatility

Solution Approach 1:

The system transitions from static HVAC design to dynamic workload management. By continuously monitoring thermal conditions and automatically migrating workloads in real-time, the system adapts to changing equipment performance and thermal patterns without requiring physical infrastructure changes, providing both effective initial management and ongoing adaptability

Inventive Principle:

AI summary

Methods, services, devices, and programmable code are provided for moving computing processes without loss of service. Powered components supporting a computing infrastructure executing computing processes are monitored for thermal characteristics, each associated with at least one of the deployed components. A thermal characteristic rule set comprising a threshold is applied to the monitored characteristics, and in response to an association with a monitored characteristic correlating with the threshold, a computing process is moved from one powered component to another having a monitored thermal characteristics not correlated with the threshold, the moving in real-time and without causing an interruption of service to an end user using the moved process.
