Equipment Bracket Air Flow Pocket for Rack Door Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard equipment, such as the CISCO ASR-1004 router, cannot be fully contained within 700 mm CI system cabinets due to service handles, requiring larger and more costly cabinets, and existing solutions for installation, like secondary equipment brackets, are difficult to install and obstruct airflow.
Innovation Solution
The design of rack-mounted equipment systems with equipment brackets that include front and rear brackets with air flow pockets and longitudinally extending prongs, allowing for easy installation, proper ventilation, and closure of the cabinet door, accommodating various equipment configurations.

Engineering Contradiction Analysis
1Volume of moving object
If standard equipment with service handles is mounted directly on rails of 700 mm CI system cabinets, then the equipment can be stored in compact cabinets, but the front doors cannot close over the service handles
Solution Approach 1:
The bracket is divided into multiple segments including a body portion, rear arm portion, and rear bracket portion, each serving specific functions. This segmentation allows the bracket to mount equipment farther back in the cabinet while maintaining structural integrity and enabling door closure.
Solution Approach 2:
The bracket extends the equipment mounting position from the front rail area to the rear rail area of the cabinet, utilizing the depth dimension. This dimensional shift allows the cabinet door to close over service handles while still accommodating the equipment.
2Ease of operation
If equipment brackets are used to mount equipment farther back in the cabinet, then the front doors can close over service handles, but the brackets are difficult to install and remove
Solution Approach 1:
The bracket is divided into separable components (body portion, rear arm portion, rear bracket portion) that can be independently manufactured and assembled. This segmentation simplifies installation and removal while maintaining the ability to close cabinet doors over service handles.
Solution Approach 2:
The bracket acts as an intermediary component between the equipment and the cabinet rails, providing a simplified mounting interface that facilitates easy installation and removal while enabling proper door closure.
3Ease of operation
If secondary equipment brackets are installed to accommodate service handles, then door closure is enabled, but the brackets obstruct required air flow for stored equipment
Solution Approach 1:
The bracket body includes air flow passages that allow air to pass through the bracket structure. This porous design enables the bracket to maintain its structural function for door closure while simultaneously facilitating required air flow to the stored equipment.
Solution Approach 2:
The bracket serves as an intermediary structure that does not block air flow but rather channels it through its internal passages, enabling both door closure and proper ventilation to the equipment.
