Card Support Assembly for Compact IHS Shock and Vibration Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reducing the size of an information handling system (IHS) chassis leads to cards being closer together, increasing the risk of damage and failure due to shock and vibration, as they deflect and come into contact with each other or the chassis walls.
Innovation Solution
A method involving a base member with moveably coupled securing members, each with card engagement features at different heights, where locking members restrict movement in specific directions to prevent card collision during vibrations, ensuring secure positioning and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the size of the IHS chassis is reduced, then the size of the IHS housing is reduced, but the cards are located closer to each other and to the chassis walls, causing them to deflect and potentially damage or fail during shock and vibration
Solution Approach 1:
The support structure is divided into multiple independent components: a base member, multiple card support members, and multiple securing members. Each card support member is independently coupled to the base member and positioned to support specific cards, allowing individual adjustment and optimization of support for each card without affecting the entire structure.
Solution Approach 2:
The securing members are designed to be moveable rather than fixed, allowing them to adapt to variations in card positions and sizes. The securing members can move along the card support members to engage with cards at different locations, providing dynamic adjustment capability to maintain reliable support during shock and vibration conditions.
2Adaptability or versatility
If multiple cards are supported in a compact space, then the device complexity increases due to the need for additional support and securing mechanisms
Solution Approach 1:
The securing members are designed to perform multiple functions: they provide mechanical support for cards, allow for adjustment to accommodate different card sizes and positions, and engage with the card support members to prevent movement. This multi-functionality reduces the need for separate components for each function.
Solution Approach 2:
The card support members are coupled to the base member in a nested arrangement, with multiple card support members positioned at different locations along the base member. The securing members are then positioned between the card support members and the cards, creating a nested structure that efficiently uses space while providing comprehensive support.

AI summary
A card supporting apparatus includes a base member. A first securing member is moveably coupled to the base member, wherein the first securing member includes a first card engagement feature located a first height above the base member. A second securing member is moveably coupled to the base member, wherein the second securing member includes a second card engagement feature located a second height above the base member, whereby the second height is different from the first height. The base member may be coupled to an information handling system chassis that includes a plurality of cards located in a spaced apart relationship to each other. The first securing member and the second securing member may then be used to support the cards in order to restrict movement of the cards.
