Engineering Contradiction Analysis
1Quantity of substance
If fiber optic distribution devices are vertically stacked on both sides of the frame to increase density, then the quantity of devices per frame is improved, but cable management complexity worsens due to increased routing difficulty
Solution Approach 1:
The frame is divided into two separate sides (left and right) with vertically stacked devices on each side. This segmentation allows independent cable management on each side while maintaining high device density. The central vertical trough acts as a separator and routing channel, organizing cables from devices on the left side from those on the right side, thereby reducing overall routing complexity despite increased device quantity.
Solution Approach 2:
The patent introduces a central vertical trough dimension that extends from the top opening through the frame. This additional spatial dimension provides a dedicated cable routing path that separates and organizes cables from devices on both sides. By utilizing this vertical central channel, the system manages the increased cable complexity resulting from doubled device density without requiring horizontal cable crossing or tangled routing.
2Ease of operation
If radius limiters are provided in vertically stacked arrangements to guide cabling between devices, then cable management is improved, but device complexity increases due to additional components
Solution Approach 1:
The radius limiters serve multiple functions: they guide cables between vertically stacked devices, maintain proper cable bend radius to prevent damage, and organize cables within the central vertical trough. By integrating these multi-functional radius limiters into the frame structure, the patent achieves improved cable management without proportionally increasing complexity, as each component performs several critical tasks simultaneously.
Solution Approach 2:
The radius limiters act as intermediary elements between the fiber optic distribution devices and the central vertical trough. They mediate the cable routing process by providing a controlled path that ensures proper cable geometry and protection, facilitating smooth cable transitions between devices while preventing direct contact between cables and sharp edges or stress points.
3Adaptability or versatility
If top and bottom openings are defined at outer edges for cable routing, then cable access flexibility is improved, but structural integrity may worsen due to additional openings
Solution Approach 1:
The frame design features asymmetric opening placement with top openings at the outer edges and a central vertical trough extending from the top. The bottom openings are positioned at outer edges but connect to a horizontal bottom trough. This asymmetric configuration provides versatile cable access from multiple directions while distributing structural stress away from concentrated weak points, maintaining frame integrity despite multiple openings.
Solution Approach 2:
The horizontal bottom trough is nested within the frame structure, connecting the bottom openings while maintaining frame rigidity. The central vertical trough is similarly integrated into the frame, extending from the top opening through the structure. These nested trough elements provide cable routing pathways without compromising the overall structural strength, as they are incorporated as integral parts of the frame design rather than separate attachments.
