Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic cable closures face issues such as kinking of buffer tubes due to edge-based organizer assemblies, the need for vertical tray positioning during splicing, and limited flexibility in accommodating various splices and components.
Innovation Solution
The proposed solution involves a fiber optic closure design with a basket and bracket assembly that includes hinge assemblies, allowing for rotatable and removable deep trays and splice modules. This design incorporates upper and lower retention tabs to manage cable routing and storage, enhancing flexibility and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional organizer assemblies with fixed edges are used, then structural simplicity is maintained, but buffer tubes kink when pulled over edges
Solution Approach 1:
The patent applies the dynamics principle by transforming fixed edges into movable, flexible edges. The organizer assembly includes flexible edges that can bend and deform to accommodate cable routing, allowing buffer tubes to be pulled over edges without kinking. This dynamic edge design adapts to different cable configurations and routing requirements, resolving the contradiction between ease of cable management and structural simplicity.
Solution Approach 2:
The patent changes the physical parameters of the organizer assembly edges from rigid to flexible. The flexible edges are designed with specific material properties and geometric configurations that allow them to deform elastically during cable installation and operation. This parameter change enables the edges to conform to cable paths while maintaining structural integrity, preventing buffer tube kinking.
2Ease of operation
If trays must be held in vertical position during splicing, then structural stability is maintained, but operational flexibility is reduced
Solution Approach 1:
The patent applies dynamics by enabling trays to rotate between vertical and horizontal positions. The tray assembly includes rotation mechanisms that allow trays to be repositioned during splicing operations. This dynamic repositioning capability provides operational flexibility while maintaining structural stability through secure mounting systems that ensure trays remain firmly positioned during use.
Solution Approach 2:
The patent segments the tray assembly into independently movable components. Each tray can be rotated and repositioned separately from the main closure structure, allowing flexible adjustment during splicing operations. This segmentation enables individual trays to be optimized for different operational requirements while maintaining overall structural integrity.
3Adaptability or versatility
If fixed splice modules are used, then manufacturing simplicity is maintained, but adaptability to different splices is limited
Solution Approach 1:
The patent applies universality by designing a standardized module interface that can accommodate multiple types of splices and components. The splice modules are designed with universal mounting features and configurable configurations that allow a single module design to support various splice types, fiber arrangements, and component combinations. This multi-functional design increases adaptability while controlling complexity through standardization.
Solution Approach 2:
The patent introduces dynamic configurability to the splice modules, allowing them to be adjusted and reconfigured for different applications. The modules include adjustable components and flexible mounting systems that enable adaptation to different splice requirements. This dynamic design provides versatility while maintaining manufacturing simplicity through modular assembly processes.

AI summary
A fiber optic closure is provided, including a base insertable at least partially into the interior of the closure. A bracket assembly includes a plurality of hinge assemblies along a transverse axis. A connector shaft connects an organizer assembly and the base together. The organizer assembly includes a main body extending between a front and a rear, a first sidewall, and a second sidewall. The main body includes a base panel extending between the first sidewall and the second sidewall and from the front to the rear. An upper retention tab extends from one or more of the first sidewall, the second sidewall, or a front wall of the main body. A lower retention tab extends from one or more walls and is positioned proximate along a transverse axis to the base panel relative to the upper retention tab.
