Modular Chassis Drawer With Side-Access Bays for Higher Density
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 periphery of the chassis, which hinders efficient addition and removal of modular resources.
Innovation Solution
A chassis 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, enabling full extension and maintaining compactness, with a backplane design that includes offset and rotated slots for efficient electrical coupling of information handling resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If information handling resources are accessed from the periphery of the chassis, then the system structure is simple, but the density of modular components is limited
Solution Approach 1:
The patent implements a nested drawer structure where the carrier member is disposed within the drawer, and bays are integrated into the carrier member. This nested arrangement allows multiple levels of component organization (drawer within chassis, carrier within drawer, bays within carrier), maximizing the density of modular components while maintaining a compact overall form factor.
Solution Approach 2:
The patent transitions from traditional peripheral access (accessing components from the side of the chassis) to front-facing access through the drawer structure. The carrier member presents bay openings at the front of the drawer, allowing components to be accessed from a different spatial dimension (front rather than side), thereby increasing component density without proportionally increasing chassis footprint.
2Ease of operation
If traditional peripheral access is used, then the chassis design is compact, but access to components is limited
Solution Approach 1:
The patent employs a dynamic drawer structure that can be extended outward from the chassis. The drawer slides on guides to provide full extension, dynamically changing the accessibility of the carrier member and its bays. This dynamic extension allows easy front-facing access to components while maintaining a compact retracted position when the drawer is closed, effectively resolving the contradiction between accessibility and compactness.
3Ease of operation
If full extension is achieved, then component access is improved, but the form factor increases
Solution Approach 1:
The patent divides the chassis into distinct functional segments: the stationary chassis body, the movable drawer, and the carrier member. This segmentation allows the drawer to provide full extension for component access while being a separate, removable component that does not permanently increase the chassis footprint. The carrier member with integrated bays is further segmented from the drawer, allowing independent optimization of each component's dimensions.

AI summary
A drawer for receiving components may include a caddy tray and at least one caddy. The caddy tray may include a substantially planar caddy tray bottom defining a caddy tray depth and a caddy tray width. The at least one caddy may be mechanically coupled to the caddy tray via a hinge mechanically coupled to the caddy tray bottom such that the caddy pivots relative to the caddy tray about the hinge, the hinge having an axis generally parallel to the caddy tray depth, the at least one caddy having 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 when the at least one caddy is pivoted from a closed position to an open position.
