Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical fiber installation kits face issues with cable damage, entanglement, and complex installation due to friction and torsion during unwinding, and lack optimized storage solutions for both the optical fiber cable and termination modules.
Innovation Solution
An optical fiber installation kit with a compartment divided by an inclined plate, featuring a figure-8 arrangement of the optical fiber cable and separate storage areas for the cable and termination module, allowing easy unwinding without supports and minimizing stress on the cable, while optimizing storage space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the optical fiber cable is stored on a reel, then the cable can be easily stored and transported, but the cable may get stuck or damaged due to friction when unwinding
Solution Approach 1:
The patent removes the reel from the installation kit entirely, extracting the source of friction and torsion problems. The cable is instead stored loosely in a storage compartment without any winding mechanism, eliminating the harmful friction that causes cable damage during unwinding.
Solution Approach 2:
The installation kit is segmented into distinct functional areas: a storage compartment for the cable and a working area for the termination module. This segmentation allows the cable to be accessed and pulled through without interference from storage mechanisms, maintaining cable integrity while preserving ease of operation.
2Device complexity
If the optical fiber cable is coiled from the reel without rotating the reel, then the installation process is simplified, but torsion is generated in the cable
Solution Approach 1:
The reel and its rotation mechanism are completely removed from the system. The cable is stored in a linear fashion in the storage compartment and can be pulled out directly without any coiling or unwinding actions, eliminating torsion generation while keeping the device simple.
3Ease of operation
If the whole length of cable is unwound before installation, then the cable can be installed in the conduit, but the installation becomes complicated and may cause entanglement
Solution Approach 1:
The cable is pre-positioned in the storage compartment with one end accessible through an opening, ready for immediate installation. This preliminary arrangement allows the installer to pull and install the cable as needed without unwinding the entire length first, simplifying the installation process while maintaining ease of operation.
Solution Approach 2:
The kit design segments the cable storage and installation areas, with the storage compartment containing the cable and the working area containing the termination module. This spatial segmentation allows cable installation to proceed without requiring complete unwinding, reducing complexity while preserving operational ease.
4Ease of operation
If a conventional installation kit with reel and opening is used, then the cable can be accessed, but storage space is not optimized and cable damage risk increases
Solution Approach 1:
The storage compartment and working area are merged into a single integrated housing structure. The cable storage compartment is designed to fit efficiently within the overall kit dimensions, optimizing storage space while maintaining easy cable access through the designed opening. This merging eliminates the need for separate reel mechanisms, reducing overall kit volume.

AI summary
An optical fiber installation kit comprises a box (1), an optical fiber cable (41) and an optical termination module (3) attached to a first end (43) of the optical fiber cable (41). The box (1) surrounds a compartment that is divided by an inclined plate (2) into a first wedge-shaped storage area (B) and a second wedge-shaped storage area (A). The first wedge-shaped storage area (B) comprises a length of the optical fiber cable looped in a folded figure-8 arrangement in which the cross over section of the folded figure-8 arrangement is placed near a narrow part of the first wedge-shaped storage area (B). The first end of the optical fiber cable is routed to the second wedge-shaped storage area, which comprises the optical termination module.
