Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional cabling is used to connect servers and TOR switches in a rack, then reliable data transmission is achieved, but the cabling becomes cumbersome and obstructs access to rack components

Engineering Contradiction:

Improvedata transmission reliabilityVSAvoidaccess to rack components

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical cabling system with a wireless communication system. Antennas are integrated into the rack structure and server units, enabling data transmission through electromagnetic waves instead of physical cables. This eliminates the obstructive cabling while maintaining communication functionality between TOR switches and servers.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If wireless communication systems are used in closely positioned rack devices, then cable obstruction is eliminated, but signal interference and degradation occur

Engineering Contradiction:

Improveaccess to rack componentsVSAvoidwireless signal interference

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent implements directional antennas with specific beamforming capabilities tailored to each local communication path. Each antenna system is optimized for its specific direction and distance to the target device, creating focused communication channels that minimize interference from adjacent devices while maximizing signal strength in the intended direction.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The wireless communication system is divided into multiple independent antenna elements that can be individually controlled and optimized. Each antenna segment communicates with specific target devices, allowing the system to manage interference by selectively activating or adjusting individual antenna segments based on communication requirements.

Inventive Principle:

Principle #1Segmentation

3Measurement precision

If directed wireless communication is used between TOR switch and servers, then communication precision is improved, but obstructions in the rack prevent or degrade the signal

Engineering Contradiction:

Improvecommunication precisionVSAvoidsignal degradation from obstructions

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent utilizes three-dimensional spatial positioning and directional beamforming to create communication paths that navigate around physical obstructions in the rack. By adding spatial dimensionality to the communication approach, the system can route signals above, below, or around obstructing components rather than being blocked by them.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces reflective surfaces and relay antenna elements as intermediaries to bounce or forward wireless signals around obstructions. These intermediary elements enable indirect communication paths that maintain signal integrity even when direct line-of-sight is blocked by rack components.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A wireless rack communication system includes a rack defining a rack entrance and device housings. A networking device is positioned in a first device housing. The networking device includes a networking device antenna system surface spaced apart from the rack entrance, and networking device antenna systems each extend from the networking device antenna system surface and into the first device housing. Server devices are each positioned in respective second device housings that are located adjacent each other on a same side of the first device housing. Each server device includes a server device antenna system surface that is spaced apart from the rack entrance and a server device antenna system that extends from that server device antenna system surface and into the respective second device housing. An unobstructed wireless communication path is provided between each server device antenna system and a respective one of the networking device antenna systems.
