Rotatable Dual-Motherboard Server Cabinet for Easier Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for larger capacity and faster servers necessitates more motherboards in a limited space, making maintenance of these motherboards difficult due to space constraints and potential damage from repeated insertion and removal of storage cards.
Innovation Solution
A cabinet design with a rotatable and movable bracket that allows for layering of upper and lower motherboards, enabling easy access and maintenance of the lower motherboard without disassembling the upper motherboard, and includes features like sliding grooves, pins, and a handle for secure positioning and locking, facilitating efficient motherboard connection and disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If more motherboards are installed to increase server capacity and running speed, then server performance is improved, but maintenance difficulty increases due to limited space
Solution Approach 1:
The bracket is designed to be rotatable between a first position (for connection) and a second position (for maintenance), transforming a static structure into a dynamic one. This allows the motherboard to be easily accessed for maintenance by simply rotating the bracket, resolving the contradiction between maintaining high server capacity and ensuring ease of maintenance.
Solution Approach 2:
The server structure is segmented into movable and fixed parts, with the bracket and motherboard assembly being separable from the main server body through rotation. This segmentation allows independent access to the motherboard without affecting other components, improving maintenance ease while preserving server performance.
2Volume of moving object
If motherboards are installed in narrow space to maximize capacity, then space utilization is improved, but maintenance accessibility deteriorates
Solution Approach 1:
The rotatable bracket provides dynamic accessibility, allowing the motherboard to be moved from a compact installed position to an exposed maintenance position. This resolves the contradiction by maintaining high space utilization during operation while providing easy access during maintenance through the rotational movement.
Solution Approach 2:
The maintenance access problem is solved by adding a rotational dimension to the otherwise planar server structure. The bracket rotates out of the server's main plane, bringing the motherboard to a different spatial dimension where it is easily accessible, thus maintaining compact volume while improving repair ease.
3Adaptability or versatility
If storage cards are frequently inserted and removed from tight interfaces, then data storage flexibility is improved, but interface damage risk increases
Solution Approach 1:
The motherboard is extracted from its installed position by rotating the bracket to the second position, removing it from the server body. This allows storage cards to be inserted or removed from the motherboard in a controlled environment away from the tight server interfaces, reducing the risk of interface damage while maintaining storage flexibility.
Solution Approach 2:
The rotatable bracket acts as an intermediary mechanism between the server body and the motherboard. It provides a controlled transition path that allows the motherboard to be moved to a maintenance position where storage card operations can be performed without directly manipulating the tight server interfaces, thus protecting them from damage.

AI summary
A cabinet of a server includes a chassis with a bottom sheet for carrying a lower motherboard and an electronic device, and a bracket positioned above the bottom sheet for carrying an upper motherboard. The bracket is rotatable and slidable relative to the chassis. When rotated upward, the bracket exposes the lower motherboard for maintenance. When rotated downward, the upper motherboard overlays the lower motherboard, allowing the bracket to slide toward the electronic device for connection. The chassis further includes a top sheet, side sheets forming a cavity, and inner sheets with sliding grooves having horizontal and vertical sections to guide the bracket's shafts. A rotatable handle on the bracket facilitates lifting and locking, enabling easy assembly and disassembly of the top sheet.
