Solution Overview

Problem

Computer system components in data centers often reach hazardous temperatures, posing safety risks during servicing, as existing cooling systems do not effectively manage temperatures in real-time to ensure safe working conditions for technicians.

Innovation Solution

A safety management module within the computer system determines when components near a target component for servicing exceed a temperature threshold, and automatically reduces their temperature using fans and cooling coils, creating a safe environment by modifying airflow and thermal conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If computer system components operate at high performance levels, then processing power and productivity are improved, but components reach hazardous temperatures that create unsafe conditions for servicing

Engineering Contradiction:
Improveprocessing powerVSAvoidhazardous temperatures
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary cooling actions before servicing begins by detecting when components are scheduled for maintenance and proactively reducing their temperatures. The safety management module identifies target components that need servicing and activates cooling mechanisms in advance, ensuring components are cooled below safe temperature thresholds before technicians begin work.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces a safety management module as an intermediary between the high-performance components and the servicing process. This module acts as a mediator that monitors component temperatures, determines when servicing is needed, coordinates with cooling systems to reduce temperatures, and manages the overall safety protocol, thereby resolving the conflict between performance and safety.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Temperature

If existing cooling systems are used, then general cooling is provided, but they do not effectively manage temperatures in real-time to ensure safe working conditions

Engineering Contradiction:
Improvecomponent coolingVSAvoidsafe working conditions
Core Design Contradiction:
TemperatureVSEase of operation

Solution Approach 1:

The system implements feedback control by continuously monitoring component temperatures through sensors and using this information to dynamically adjust cooling actions. The safety management module receives temperature data, compares it against safe thresholds, and activates or adjusts cooling mechanisms based on real-time conditions, ensuring components are kept at safe temperatures during servicing operations.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The cooling system transitions from static, predetermined cooling to dynamic, adaptive cooling that responds to real-time operational conditions. The safety management module continuously adjusts cooling actions based on current component temperatures, workload conditions, and servicing schedules, making the cooling system flexible and responsive to changing thermal conditions rather than operating on fixed parameters.

Inventive Principle:
Principle #15Dynamics
