Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If fiber optic equipment is mounted in standard equipment racks with traditional tray configurations, then ease of operation and maintenance is improved, but fiber optic cable packing density and connection density are limited
Solution Approach 1:
The equipment rack is divided into multiple tray levels, with each tray independently configurable to hold specific fiber optic modules. The tray structure itself is segmented into multiple compartments or bays that can accommodate different types of fiber optic connections, allowing high density while maintaining organizational structure and ease of access to specific segments.
Solution Approach 2:
The invention utilizes vertical stacking of trays in the equipment rack to increase connection density without expanding horizontal footprint. By arranging fiber optic modules in multi-layer tray configurations and utilizing vertical space efficiently, the system achieves high packing density while maintaining standard rack mounting dimensions and accessibility.
2Quantity of substance
If the quantity of fiber optic cables is increased to support larger numbers of connections, then bandwidth and connection density are improved, but space requirements and cable management complexity increase
Solution Approach 1:
Fiber optic modules are nested within tray compartments, which are nested within the equipment rack structure. The tray design allows modules to be inserted and removed independently while remaining contained within the organized tray structure, maximizing space utilization and enabling high connection density within compact dimensions.
Solution Approach 2:
The invention changes the spatial arrangement parameters of fiber optic modules by utilizing vertical stacking, compact module dimensions, and optimized tray geometries. By adjusting these physical parameters and configuring modules in high-density patterns, the system increases the number of connections per unit area while maintaining proper cable routing and access.
3Quantity of substance
If fiber optic modules are configured for high connection density, then bandwidth capacity is improved, but access and maintenance of individual modules becomes more difficult
Solution Approach 1:
The tray is segmented into multiple independent bays or compartments, each capable of holding one or more fiber optic modules. This segmentation allows technicians to access and maintain specific modules by opening only the relevant tray or compartment, rather than accessing the entire high-density array, thus maintaining ease of operation while achieving high connection density.
Solution Approach 2:
The tray design incorporates movable or removable components that allow dynamic access to modules. Trays can be extended outward, individual module holders can be released, or compartments can be opened to provide clear access paths to densely packed modules, enabling maintenance operations without disrupting other parts of the high-density configuration.
