Engineering Contradiction Analysis
1Area of stationary object
If optical networks stretch access over greater distances to serve rural areas, then broadband coverage is improved, but latency increases
Solution Approach 1:
The patent segments the centralized cloud computing function into distributed edge computing nodes placed at multiple locations along the optical network (enclosures at different distances from the OLT). This segmentation allows users to access computing resources from the nearest edge node, reducing the effective distance and latency while maintaining broad geographic coverage.
Solution Approach 2:
The patent adds a spatial dimension to the network architecture by deploying edge compute nodes at multiple geographic locations rather than relying on a single centralized data center. This dimensional expansion creates multiple access points, allowing users to connect to the closest node and thereby reducing latency while extending coverage area.
2Loss of time
If more computational processing is performed at the edge, then latency is reduced, but device complexity increases
Solution Approach 1:
The patent designs edge compute nodes with universal, multi-functional capabilities that can handle various computational tasks (video processing, data analytics, application hosting) within a single standardized unit. This multi-functionality reduces the need for multiple specialized devices, thereby managing complexity while providing comprehensive edge computing services.
Solution Approach 2:
The patent uses standardized, replicated edge compute node designs that can be deployed uniformly across multiple locations. Instead of designing unique complex systems for each location, the same proven hardware and software template is copied and deployed, which simplifies the complexity management through standardization while maintaining consistent performance across the network.
3Quantity of substance
If edge compute nodes are integrated into existing enclosures, then infrastructure cost is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs modular, dynamically configurable mounting systems within existing enclosures that can adapt to different edge compute node sizes and power requirements. This dynamic mounting approach uses adjustable brackets, flexible power routing, and reconfigurable cable management, which reduces the need for precision manufacturing of custom enclosures while enabling flexible integration.
Solution Approach 2:
The patent utilizes parameter changes in the enclosure environment (such as adjustable mounting positions, variable power supply configurations, and flexible spatial arrangements) to accommodate edge compute nodes without requiring precise manufacturing tolerances. By making the enclosure parameters adjustable rather than fixed, the system achieves accurate integration through configuration rather than manufacturing precision.

AI summary
Optical networks including edge compute nodes disposed in enclosures along passive optical networks are provided. An enclosure for a passive optical network includes a housing selectively enclosing an internal volume which houses one or more passive optical components; and an edge compute node disposed in the internal volume and configured to be in optical communication with an optical line terminal and an optical network unit of the optical fiber network.
