Solution Overview

Problem

Information handling systems face challenges in reducing the provision of wireless communication access while maintaining security, as users may not desire a wireless interface on servers, and existing designs often compromise on space for wireless interfaces and security.

Innovation Solution

An information handling system with a management controller for out-of-band management, enabling communication between a processor and a second system via an interface, allowing secure management without a visible wireless interface, using a bezel to house a wireless communication module that can be accessed externally for management purposes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a wireless interface is provided on the server front panel, then wireless communication access is enabled, but security concerns increase and space for hard disk drive bays is reduced

Engineering Contradiction:
Improvewireless communication accessVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The wireless communication module is extracted from the main server chassis and relocated to a separate removable bezel assembly. This extraction allows the wireless interface to be provided when needed while eliminating security concerns when the bezel is removed, as the wireless capability is physically separated from the main system.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The bezel assembly with the wireless communication module is designed to be dynamically removable and reattachable to the server chassis. This dynamic configuration allows the system to transition between having wireless access enabled and disabled, providing flexibility to match security requirements while maintaining the capability when needed.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If a wireless interface is provided on the server front panel, then wireless communication access is enabled, but space for hard disk drive bays is reduced

Engineering Contradiction:
Improvewireless communication accessVSAvoidspace for hard disk drive bays
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The wireless communication module is extracted from the main server chassis and relocated to a separate removable bezel assembly. This extraction frees up space in the main chassis for hard disk drive bays while maintaining wireless capability through the separate bezel attachment.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The wireless communication functionality is moved from the two-dimensional front panel plane to a separate dimensional space (the removable bezel assembly). This allows the main chassis to maintain its space allocation for storage drives while wireless access is provided through the attached bezel.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If out-of-band management is implemented, then secure management is enabled, but device complexity increases

Engineering Contradiction:
Improvesecure managementVSAvoidmanagement controller configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The management controller is integrated into the bezel assembly itself, allowing it to autonomously provide out-of-band management capabilities. This self-service approach enables secure management without requiring complex external infrastructure, as the bezel contains its own management functionality.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The management controller functionality is merged with the bezel assembly, combining security management capabilities with the physical access control mechanism. This integration simplifies the overall system architecture by consolidating management functions into the existing bezel structure rather than adding separate complex management infrastructure.

Inventive Principle:
Principle #5Merging (Combining)
