Modular Chassis Drawer Structure for Dense Side-Access Bays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional modular information handling systems face limitations in density due to restricted access to components, as they are typically accessed from the side of the chassis, which hampers the efficient addition and removal of modular resources.
Innovation Solution
A drawer system comprising an inner member, intermediate member, and carrier member, where the carrier member slides relative to the inner and intermediate members, allowing bays to be accessed from the side when the drawer is open, enabling full extension and maintaining the height of the chassis for easy installation of information handling resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If information handling resources are accessed from the side of the chassis, then the ease of operation is improved, but the density of modular components is limited
Solution Approach 1:
The patent implements a nested drawer structure where multiple drawers are arranged vertically within the chassis, with each drawer containing multiple bays for information handling resources. This nesting approach allows dense packing of components while maintaining side accessibility, as the entire drawer assembly can be pulled out from the side for access to multiple bays simultaneously.
Solution Approach 2:
The patent transitions from traditional horizontal arrangement of components to a vertical stacking arrangement of drawers, each containing multiple bays. This dimensional change from primarily horizontal to vertical organization increases the density of modular components while preserving side access capability, as the vertical stack can be accessed from the side by pulling out the appropriate drawer.
2Quantity of substance
If multiple drawers are stacked vertically, then the density of modular components is improved, but the device complexity increases
Solution Approach 1:
The patent divides the chassis into multiple independent drawer modules, each drawer containing multiple bays for information handling resources. This segmentation allows each drawer to be a self-contained unit that can be independently manufactured, installed, and maintained, reducing overall system complexity despite the increased number of components through modularization.
Solution Approach 2:
The patent designs the drawers with universal characteristics where each drawer can accommodate multiple types of information handling resources in its bays, and the drawer structure itself serves multiple functions: structural support, access control, and organizational framework. This multi-functionality reduces the need for specialized components for each function, thereby managing complexity.
3Ease of operation
If bays are accessed from the side of the chassis, then the ease of operation is improved, but the volume utilization of the chassis is reduced
Solution Approach 1:
The patent nests multiple bays within each drawer, and multiple drawers within the chassis, creating a nested hierarchical structure. This allows efficient volume utilization as the nested arrangement maximizes the use of available chassis space while maintaining side accessibility, since the entire nested drawer structure can be pulled out from the side for access to all bays within that drawer.
Solution Approach 2:
The patent utilizes vertical stacking of drawers to maximize volume utilization, transitioning from horizontal to vertical space usage. This dimensional change allows the chassis to efficiently use its volume capacity while preserving side access capability, as the vertical arrangement of drawers can be accessed from the side by pulling out the appropriate drawer level.

AI summary
A drawer for receiving components may comprise an inner member, and intermediate member, and a carrier member. The carrier member may comprise a substantially planar top generally parallel to an inner member bottom, a substantially planar bottom generally parallel to the top, a carrier spine mechanically coupled between the top and the bottom, a plurality of bays, each bay having one or more structural components for receiving a modular information handling resource and configured such that the bay is accessed for insertion or removal of the modular information handling resource via a carrier member side of the carrier member generally parallel to an inner member side, and at least one web generally parallel to the inner member sides and mechanically coupling the carrier member to the intermediate member such that when the drawer is translated to an open position, each of the plurality of bays is accessible.
