Hinged Structural Side Wall for Front Access PCIe CEM Card Bay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems face challenges in servicing PCIe CEM form factor devices due to space constraints and structural integrity issues when accessing I/O devices from the front, which compromises the server's capacity and structural integrity.
Innovation Solution
A removable I/O device bay system with a hinged structural side wall that pivots between open and closed positions, allowing easy installation and removal of PCIe CEM cards from the front, featuring a modular card housing, spring mechanism for retention, and thumbscrew fastening, minimizing space requirements and maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a removable device bay is added to allow front servicing of PCIe CEM cards, then serviceability is improved, but device complexity increases
Solution Approach 1:
The device bay is designed as a separate, removable module that can be detached from the main server chassis. This segmentation allows the bay to be serviced independently while maintaining the integrity of the core server system, thereby improving serviceability without permanently increasing overall device complexity.
Solution Approach 2:
The device bay incorporates a hinged side wall that pivots between open and closed positions, enabling dynamic access to PCIe CEM cards. This mechanical movement allows technicians to service cards from the front without permanently opening the server, balancing ease of repair with structural integrity.
2Strength
If the hinged side wall is made structural to maintain integrity, then strength is improved, but ease of operation deteriorates
Solution Approach 1:
The hinged side wall is designed with pivot points and locking mechanisms that allow it to function as a structural element when closed while remaining easily operable when needed. The hinge design enables smooth movement despite the structural nature of the wall, resolving the contradiction between strength and ease of operation.
3Ease of operation
If the device bay is designed for front access, then ease of operation is improved, but space utilization deteriorates
Solution Approach 1:
The device bay utilizes the front access dimension by positioning PCIe CEM card slots on the side wall that faces the front of the server. This dimensional arrangement allows cards to be accessed from the front without requiring additional depth or volume in the traditional server interior space, thereby maintaining efficient space utilization while enabling easy front access.
