Split Bezel Hinge Doubles Blade Server Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a continuous pressure to increase computing density in datacenters by efficiently utilizing existing chassis space, as traditional blade servers have limitations in accommodating additional computing devices within their form factor.
Innovation Solution
A double-dense blade server design featuring two hinged housing portions that pivot and latch to create a common housing, allowing for the integration of two servers within the same form factor, with electromagnetic compatibility and airflow considerations, and secure latching mechanisms to ensure reliable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a double-dense blade server design is implemented to double computing capacity, then computing density is improved, but housing structure complexity increases
Solution Approach 1:
The housing is divided into two separate housing portions that can be independently assembled and then joined together. Each housing portion contains one server blade, allowing the complex double-dense configuration to be built from simpler modular units. This segmentation reduces the overall design complexity by breaking down the integration challenge into manageable parts.
Solution Approach 2:
Two separate housing portions are merged into a single common housing structure that accommodates two server blades. The hinge members and latching mechanisms enable these portions to be joined while maintaining access to both servers, effectively combining two independent units into one integrated double-dense server system.
2Ease of operation
If hinge members are used to enable pivoting between open and closed positions, then ease of operation is improved, but reliability may worsen due to additional moving parts
Solution Approach 1:
The hinge members enable dynamic pivoting of the housing portions between open and closed positions, providing operational flexibility. This dynamic mechanism allows technicians to access servers for maintenance or installation while maintaining a secure closed position during operation, balancing ease of operation with operational reliability.
Solution Approach 2:
Latching mechanisms serve as intermediaries between the hinge members and the housing portions, providing a reliable connection when the housing is in the closed position. These latches mediate the connection, ensuring that the dynamic hinge movement translates into a stable, reliable closed state that maintains structural integrity and connection security.

AI summary
A blade server comprises first and second housing portions. Each housing portion includes a cover securing a first printed circuit board assembly, two sides extending from the cover, a bezel portion secured along a proximal end of the cover between the two sides, a first hinge member formed near the proximal end of one side, and a second hinge member formed near the proximal end of the other side. The hinge members on the first housing portion are selectively engagable with the hinge members on the second housing portion to enable the housing portions to pivot between an open position and a closed position with the first and second printed circuit board assemblies disposed between the first and second housing portions.
