Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fiber optic telecommunications networks face challenges in efficiently and cost-effectively distributing fiber optic communications services to local areas, particularly in the installation and maintenance of fiber optic drop terminals, which require complex and labor-intensive processes.
Innovation Solution
The development of a fiber optic drop terminal assembly with a housing, spool, and ruggedized adapters, allowing for efficient installation by rotating the housing and spool in unison as the fiber optic distribution cable is paid out, and the use of pre-spooled cables to simplify the mounting process, reducing labor and material costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fiber optic drop terminal installation methods are used, then the installation process is complex and labor-intensive, but the reliability of fiber optic networks is maintained
Solution Approach 1:
The fiber optic distribution cable is pre-spooled on the spool at the drop terminal assembly before installation. This preliminary preparation allows the cable to be easily deployed by simply rotating the spool during installation, eliminating the need for complex cable routing and handling procedures that would otherwise be required
Solution Approach 2:
The spool acts as an intermediary mechanism between the fiber optic distribution cable and the installation process. By introducing this intermediate component, the complex task of cable management is simplified to a simple rotational motion of the spool, making the installation process much easier while maintaining cable integrity
2Productivity
If traditional fiber optic drop terminal installation methods are used, then the installation process is complex and labor-intensive, but the structural integrity of the terminal is maintained
Solution Approach 1:
The cable is pre-spooled on the spool before installation, which prepares the system in advance for rapid deployment. This preliminary action transforms a complex multi-step cable installation procedure into a simple process of rotating the spool, significantly improving installation productivity
Solution Approach 2:
The spool is designed to rotate freely to pay out the fiber optic distribution cable during installation. This dynamic mechanism allows the cable length to be easily adjusted by simply rotating the spool, eliminating the need for complex cutting, joining, and routing operations that would reduce productivity
3Ease of manufacture
If pre-spooled cables are used to simplify the mounting process, then labor costs are reduced, but the device structure becomes more complex
Solution Approach 1:
The cable is pre-spooled on the spool during manufacturing or before installation. This preliminary preparation simplifies the mounting process to a simple spool rotation operation, reducing labor requirements while the added structural complexity is confined to the spool mechanism which is a single, integrated component
Solution Approach 2:
The spool serves multiple functions: it stores the fiber optic distribution cable, enables easy cable deployment through rotation, and provides a mechanical interface for cable payment during installation. By consolidating these multiple functions into a single universal component, the increase in device complexity is minimized while achieving significant simplification of the mounting process
