Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple fiber distribution cabinets are combined to meet 144 cores in 1 U space, then core density requirement is met, but space occupation and cost increase
Solution Approach 1:
The patent merges multiple fiber distribution functions into a single integrated tray structure that can accommodate 144 cores within 1 U space. The tray body integrates input mounting areas, output mounting areas, fiber storage areas, and terminal areas into one compact unit, eliminating the need for multiple separate cabinets and achieving high core density while reducing space occupation.
Solution Approach 2:
The patent utilizes three-dimensional space optimization by arranging fiber adapters, storage areas, and terminal areas in vertical and horizontal configurations within the tray body. The slide rail mechanism enables vertical movement along the Z-axis, while the tray accommodates multiple layers of adapters and fibers, effectively using spatial dimensions to increase core capacity without proportionally increasing footprint area.
2Device complexity
If traditional fiber distribution trays are used, then structure is simple, but space utilization rate is low and density improvement is limited
Solution Approach 1:
The tray body is segmented into distinct functional areas including input mounting areas, output mounting areas, fiber storage areas, and terminal areas. This segmentation allows each region to be optimized for its specific function while maintaining overall compactness. The cover body is also separable to provide access to internal components, enabling efficient space utilization without excessive complexity.
Solution Approach 2:
The tray body serves multiple functions simultaneously: it provides structural support, organizes fiber adapters, stores excess fiber length, facilitates mode conversions between different connector types (LC, SC, MTP/MPO), and enables flexible mounting and maintenance through the slide rail mechanism. This multi-functionality increases space utilization rate without requiring multiple separate devices.
3Adaptability or versatility
If different distribution trays are switched for mode conversions among LC, SC and MTP/MPO, then mode conversion is achieved, but production and use cost increases
Solution Approach 1:
The tray body is designed with universal adaptability to accommodate multiple fiber adapter types including LC, SC, and MTP/MPO connectors within the same structure. The input and output mounting areas can be configured with different adapter types, and the fiber storage area accommodates corresponding cables. This eliminates the need to switch between different distribution trays for mode conversions, reducing both production costs and operational complexity.
Solution Approach 2:
The tray body can be dynamically reconfigured by removing and replacing adapter modules or by utilizing the slide rail mechanism to adjust the position and orientation of fiber connections. This dynamic flexibility allows the same tray structure to adapt to different mode conversion requirements without requiring multiple dedicated trays, thereby reducing costs.
4Stability of the object's composition
If distribution tray is fixed in distribution cabinet, then mounting is stable, but maintenance and cable distribution flexibility is reduced
Solution Approach 1:
The tray body is equipped with a slide rail mechanism that enables it to move horizontally along the X-axis within the distribution cabinet while maintaining stable mounting through limit blocks and clamp buckles. This dynamic positioning capability allows the tray to be easily removed for maintenance or cable distribution activities, then repositioned and secured back in place, combining mounting stability with operational flexibility.
Solution Approach 2:
The separable cover body design allows the top cover to be removed independently from the tray body for maintenance access without removing the entire tray from the cabinet. This segmentation provides flexible maintenance capability while the tray body remains stably mounted through the slide rail mechanism, balancing mounting stability with ease of operation.
