Solution Overview

Problem

Edge devices in information handling systems face challenges in maintaining minimum temperature compliance while optimizing power usage, as they often require heaters to operate within ASHRAE thermal recommendations, leading to high power consumption and inefficiency, and there is a risk of temperature violations due to absent or malfunctioning heater elements.

Innovation Solution

An information handling system monitors edge devices to detect temperature deviations and uses a combination of a healthy heater and workload management to maintain minimum temperature thresholds, activating the heater or adjusting workload to ensure compliance with ASHRAE recommendations while optimizing power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If heaters are used to maintain minimum temperature in edge devices, then temperature compliance is improved, but power consumption increases

Engineering Contradiction:

Improveminimum temperature complianceVSAvoidpower consumption

Core Design Contradiction:

TemperatureVSUse of energy by moving object

Solution Approach 1:

The system uses the edge device's own workload to generate heat and maintain temperature, rather than relying on dedicated heater elements. The workload itself serves the dual purpose of processing data and thermal maintenance, eliminating the need for separate heating components and their associated power consumption.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The workload performs multiple functions simultaneously: it processes information and generates thermal energy to maintain minimum temperature requirements. This multi-functionality eliminates the need for dedicated heater elements, reducing both device complexity and power consumption while maintaining temperature compliance.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Temperature

If heater elements are used to maintain temperature, then temperature compliance is improved, but device complexity increases

Engineering Contradiction:

Improveminimum temperature complianceVSAvoidheater element management

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

The patent removes the heater element component from the system entirely, extracting the heating function from a dedicated hardware component and replacing it with a software-controlled workload mechanism. This simplifies the device by eliminating additional hardware that would require management, monitoring, and maintenance.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical/physical heater element with a software-based workload mechanism. Instead of using electrical heating components, the system uses computational workload to generate thermal energy, substituting a software-controlled process for a physical hardware component.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Temperature

If workload is increased to generate heat, then temperature compliance is improved, but processing efficiency decreases

Engineering Contradiction:

Improveminimum temperature complianceVSAvoidprocessing efficiency

Core Design Contradiction:

TemperatureVSProductivity

Solution Approach 1:

The system applies workload selectively and partially - only enough to maintain minimum temperature requirements, not excessive workload that would compromise processing efficiency. The workload is tuned to provide just sufficient thermal energy while minimizing impact on productivity.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system dynamically adjusts workload levels based on real-time temperature monitoring and environmental conditions. The workload is not static but adapts to maintain temperature compliance while optimizing processing efficiency, increasing only when necessary and decreasing when ambient conditions provide sufficient heat.

Inventive Principle:

Principle #15Dynamics

AI summary

An information handling system monitors an edge device to detect whether a current temperature of the edge device is below a minimum system temperature threshold. If the current temperature is below the minimum system temperature threshold, then the system determines whether the edge device includes a heater. If a current system workload of the edge device is greater than a minimum system workload threshold and the heater is healthy, then the system uses the heater to increase the current temperature of the edge device to the minimum system temperature threshold.
