Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary stacking cables are used to connect networking devices in a stack, then the devices can communicate reliably, but the cables are bulky and hinder cooling and access to power systems
Solution Approach 1:
The patent removes the physical stacking cables from the system entirely, extracting the harmful element that obstructed cooling while preserving the essential function of device communication through alternative wireless means
Solution Approach 2:
The patent replaces the mechanical cable-based connection system with an optical wireless communication system, eliminating the need for physical connectors and cables that blocked cooling pathways
2Adaptability or versatility
If proprietary stacking cables are used for different hardware platforms, then each platform can operate correctly, but spare part proliferation occurs and troubleshooting becomes difficult
Solution Approach 1:
The patent implements a universal optical communication interface that works across all networking device platforms, eliminating the need for platform-specific cable types and simplifying spare part management to a single standardized component
Solution Approach 2:
The patent standardizes the stacking communication interface across all hardware platforms, creating homogeneous connectivity requirements that reduce complexity in spare part inventory and troubleshooting procedures
3Reliability
If stacking cables are used to connect devices, then data communication is established, but the cables are difficult to connect and troubleshoot
Solution Approach 1:
The patent replaces mechanical cable insertion and connection operations with automated optical signal transmission, eliminating the manual dexterity requirements and connection complexity associated with physical cable assembly

AI summary
A cable free networking device stacking system includes networking devices that are each configured to operate as part of a networking device stack, and at least one LiFi device included on each of the networking devices. A first LiFi device on a first networking device in the plurality of networking devices transmits networking device stack data communications by receiving first electrical data communications from the first networking device, converting the first electrical data communications to first optical data communications, and wirelessly transmitting the first optical data communications to a second LiFi device included on a second networking device in the plurality of networking devices. The first LiFi device also receives networking device stack data communications by wirelessly receiving second optical data communications from the second LiFi device, converting the second optical data communications to second electrical data communications, and transmitting the second electrical data communications to the first networking device.
