Fan Tray Side Wall Rotation for Cable Access and Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fan tray systems in server chassis fail to maximize server feature sets due to challenges in tool-less installation, minimizing access steps, and efficient cable routing without impacting airflow.
Innovation Solution
A fan tray system with a moveable coupling mechanism allowing the fan tray side wall to rotate between two orientations, enabling tool-less installation, simplified cable routing, and access to components impeded by the fan tray in its first orientation, while maintaining airflow directionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fan tray side wall is positioned adjacent the chassis wall to maintain structural integrity and airflow directionality, then airflow integrity is improved, but access to cables routed adjacent the chassis wall is impeded
Solution Approach 1:
The fan tray side wall is made movable rather than fixed, allowing it to be positioned in a first configuration adjacent the chassis wall for airflow integrity, and a second configuration away from the chassis wall for cable access. The moveable coupling enables the side wall to rotate between these configurations.
Solution Approach 2:
The side wall movement is achieved through rotation around an axis, transitioning from a position blocking cable access to a position allowing access, effectively using rotational movement to resolve the spatial conflict between airflow requirements and cable accessibility.
2Device complexity
If conventional fan trays are used to maintain simple structure, then device complexity is reduced, but tool-less installation and minimized access steps cannot be achieved
Solution Approach 1:
The moveable coupling mechanism allows the side wall to rotate between configurations, enabling tool-less installation by allowing the side wall to be positioned for access during installation, then secured in the airflow-optimized position.
Solution Approach 2:
The fan tray is divided into separable components including the base, side walls, and moveable coupling mechanisms, allowing independent manipulation of each component for easier installation and maintenance without requiring tools.
3Stability of the object's composition
If the fan tray side wall remains fixed in its first orientation, then structural stability is maintained, but cable routing and component access become difficult
Solution Approach 1:
The side wall transitions from a fixed structure to a dynamically adjustable component that can be rotated between a stable first configuration for airflow and a second configuration for cable routing and component access.
Solution Approach 2:
The moveable coupling acts as an intermediary mechanism between the fixed base and the movable side wall, enabling controlled rotation and position changes while maintaining structural connection.

AI summary
A fan tray system includes a fan tray base that couples to a chassis and that includes fan system connector(s) for connecting to a fan system. A fan tray side wall includes fan system guide member(s) that align the fan system for connection to the fan system connector(s), and is connected to the fan tray base by a moveable coupling that allows relative movement between the fan tray side wall and the fan tray base. That relative movement allows the fan tray side wall to be positioned in a first orientation when the fan tray base is coupled to the chassis such that the fan tray side wall is positioned adjacent a chassis wall of the chassis and impedes access component(s) in the chassis. That relative movement also allows the fan tray side wall to be moved to a second orientation that allows access to the component(s) in the chassis.
