Solution Overview

Problem

Information Handling Systems (IHS) face challenges in achieving consistent performance due to variations in IHS components from different providers, leading to inconsistent behavior and increased design costs, as conventional solutions often require dictating specific components, which can result in unnecessary design efforts and resource overhead.

Innovation Solution

A component control system that includes a component controller capable of receiving a normalized component performance (NCP) value from the IHS controller, providing control signals to ensure component outputs fall within specified ranges, allowing components from different providers to operate consistently across IHS systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the IHS provider dictates specific component elements of IHS components, then consistent performance across IHS systems is improved, but device complexity and design costs increase

Engineering Contradiction:
Improveconsistent performanceVSAvoiddesign complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by establishing normalized performance parameters and output ranges that component elements must satisfy. Instead of dictating specific components, the IHS provider defines performance thresholds (e.g., airflow ranges, temperature ranges, power consumption ranges) that allow multiple component designs to achieve consistent system performance. This resolves the contradiction by maintaining reliability through parameter control while reducing design complexity by allowing component provider flexibility.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements universality by creating a standardized interface and performance framework that works across multiple component providers and designs. The normalized control approach establishes universal performance criteria that can accommodate diverse component implementations, allowing the same control methodology to manage different PSU designs, fan configurations, and thermal solutions from various providers while maintaining consistent IHS performance.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of manufacture

If the IHS provider allows flexibility in component selection from multiple providers, then ease of manufacture and cost are improved, but performance consistency deteriorates

Engineering Contradiction:
Improvecomponent procurement flexibilityVSAvoidperformance consistency
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent resolves this contradiction by shifting from component-specific control to parameter-based control. The IHS provider specifies performance parameters (output ranges for temperature, airflow, power consumption) rather than specific components. Component providers can select different implementations as long as they meet the normalized performance criteria, thereby maintaining both manufacturing flexibility and performance consistency.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs feedback mechanisms where component elements report their actual performance parameters to the controller, which then adjusts control signals to maintain outputs within specified ranges. This closed-loop control ensures that regardless of which component provider's elements are used, the system achieves consistent performance through continuous monitoring and adjustment based on feedback from sensors and component status reports.

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If specific fans are dictated for PSU design, then airflow consistency is improved, but manufacturing cost and design effort increase

Engineering Contradiction:
Improveairflow consistencyVSAvoiddesign effort
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent applies parameter changes by defining acceptable airflow output ranges rather than specifying particular fan models. The PSU controller receives normalized control signals and adjusts fan operation to maintain airflow within the specified range. This allows PSU providers to select different fan designs that can achieve the required airflow performance, reducing design effort while maintaining manufacturing precision through parameter-based control.

Inventive Principle:
Principle #35Parameter changes

AI summary

A component control system includes a component. At least one component element is included in the component. A component controller is included in the component, coupled to the at least one component element, and operable to couple to an Information Handling System (IHS) controller. The component controller is operable to receive a normalized component performance (NCP) value from the IHS controller. The NCP value is associated with at least one component output range. The component controller is also operable to provide a control signal that is associated with the NCP value to the at least one component element. In response to receiving the control signal, the at least one component element operates such that the component produces at least one component output, and each component output produced by the component is within a corresponding component output range.
