Half-Rack Cabinet Articulating Wall Mount for Back-Plane Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a compact, wall-mountable half-rack cabinet that provides easy access to the back planes of electronic modules, security for back-plane connections, and the ability to mix half-rack and full-rack modules within the same cabinet, while minimizing floor space and maintaining an economical design.
Innovation Solution
A half-rack cabinet with a lockable and articulatable wall mounting system utilizing doubly nested four-bar mechanisms, allowing rotation of the cabinet to access the back panels and accommodating both half-rack and full-rack modules with crossbars for vertical mounting, ensuring efficient use of space and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the cabinet is wall-mounted in a fixed position, then floor space is minimized, but access to the back planes of modules becomes difficult
Solution Approach 1:
The cabinet incorporates an articulating mechanism with doubly nested four-bar linkages that enable the cabinet to rotate between a retracted position (minimizing floor space) and an extended position (providing access to back planes). This dynamic transformation allows the same structure to fulfill both spatial efficiency and operational accessibility requirements.
2Ease of manufacture
If the cabinet structure is simplified, then manufacturing cost is reduced, but security for back-plane connections is compromised
Solution Approach 1:
The cabinet is divided into modular components including the cabinet body, articulating mechanism with four-bar linkages, locking mechanism, and mounting bracket. This segmentation allows each component to be manufactured separately using standard fabrication processes, reducing overall manufacturing complexity and cost while maintaining security through dedicated locking features.
3Volume of moving object
If the cabinet is designed for half-rack modules only, then compactness is improved, but versatility is reduced
Solution Approach 1:
The cabinet employs adjustable shelving systems and configurable mounting configurations that can accommodate various module sizes including half-rack, full-rack, and mixed arrangements. The articulating mechanism and locking system are designed to secure different module configurations, enabling a single compact cabinet design to serve multiple installation scenarios.

AI summary
A half-rack electronics cabinet coupled to a wall mount by two doubly-nested four bar mechanisms that are operable to articulate the cabinet by ninety degrees to bring the back planes of any installed electronic modules to the top for easy access. The function of admitting outside signal and power cables is apportioned to the wall mount. The unit is compact, as the wall mount is no wider than the cabinet. For a half-rack cabinet of sufficient height, crossbars are provided that enable vertical mounting of full-rack electronic modules in the half-rack cabinet along with, preferably, at least one half-rack module.
