Problem

Data centers face challenges with cabling issues such as 'spaghetti cabling' due to inflexible cable ports and limited space on server racks, which restricts scalability and increases maintenance complexity, and limits the number of cable ports that can be physically implemented.

Innovation Solution

The implementation of extremely high frequency (EHF) communication devices to form EHF electromagnetic communication channels within server racks, allowing for wireless data transfer between components, thereby reducing the need for physical cables and increasing bandwidth without the constraints of traditional cable ports.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If cable ports are increased to increase bandwidth, then bandwidth is improved, but the number of cable ports that can be physically implemented is limited by space constraints

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The patent replaces the mechanical cable connection system with an electromagnetic communication system. EHF communication devices transmit data wirelessly through electromagnetic signals, eliminating the need for physical cables and cable ports. This substitution resolves the space constraint issue while providing high-bandwidth communication between rack mountable devices.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent transitions from two-dimensional cable port arrangements on the back panel to three-dimensional wireless electromagnetic signal propagation through the rack space. EHF signals can penetrate through rack structures and communicate with devices on multiple sides simultaneously, effectively utilizing the three-dimensional space within the rack rather than being constrained to the two-dimensional back panel surface.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A system, such as a server rack, includes rack mountable devices that communicate using one or more extremely high frequency (EHF) communication devices. A rack mountable device includes a rack mountable chassis including multiple sides, and a circuit board along a side of the rack mountable chassis, the circuit board having a surface. The EHF communication devices are positioned along the side of the rack mountable chassis and attached to the surface of the circuit board. Each of the EHF communication devices is configured to convert between an EHF electromagnetic signal and an electrical data signal. The EHF communication devices form EHF communication channels with other EHF communication devices in other rack mountable devices, or in the server rack to provide high bandwidth data transfer utilizing space on the sides of the rack mountable device.
