Fiber Distribution Frame Pop-Up Cassette Extraction Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Densely installed cassettes in fiber distribution frames lack sufficient space for easy replacement or disassembly, making it difficult to withdraw intermediate cassettes.
Innovation Solution
A multi-cassette fiber distribution frame with pop-up parts and suppressors that apply elastic pressure to cassettes, allowing easy extraction and assembly, featuring holders with guide rails and slots for cassette support and a frame structure that facilitates cassette insertion and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cassettes are densely installed without clearance to maximize the number of cassettes in a compact space, then the quantity of cassettes increases and the frame size is reduced, but the ease of operation deteriorates because sufficient space for gripping and replacing cassettes cannot be secured
Solution Approach 1:
The holder is divided into a fixed part and a movable part that can be separated. The movable part can be detached to provide access to cassettes, allowing workers to grip and replace cassettes even when densely installed. This segmentation enables the holder structure to adapt between a compact closed state and an open state for maintenance operations.
Solution Approach 2:
The holder incorporates a movable part that can transition between different positions. When the movable part is retracted, cassettes are tightly packed for space efficiency. When the movable part is extended or removed, it creates clearance for cassette manipulation. This dynamic structure allows the same system to optimize for both storage density and operational accessibility.
2Volume of stationary object
If cassettes are densely installed in a stacked structure to maximize space utilization, then the frame size is minimized, but the ease of operation deteriorates making it very difficult to withdraw intermediate cassettes
Solution Approach 1:
The holder is segmented into fixed and movable parts that can be separated. For intermediate cassettes, the movable part can be detached to create access pathways, enabling workers to reach and withdraw cassettes from the middle of the stack without needing to remove outer cassettes or have significant clearance between all cassettes.
Solution Approach 2:
The movable part of the holder acts as an intermediary mechanism between the worker and the cassette. By detaching or moving this intermediate component, direct access to the cassette is provided, solving the problem of reaching intermediate cassettes in a densely packed configuration without requiring the entire stack to be sparse.
