Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of fiber optic networks in indoor settings, particularly in multi-dwelling units and block of flats, is complex and costly due to the need for numerous cables and requires skilled technicians, leading to time-consuming and expensive routing through walls and building levels.
Innovation Solution
A novel fiber optic distribution device with a housing that includes removable wall sections, grommets, and a splice tray for easy installation, allowing for efficient routing of riser, tether, and drop cables, reducing the need for extensive cabling and skilled labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard fiber optic distribution devices are used with multiple separated cables for each subscriber, then connection reliability is improved, but installation complexity and cost increase significantly
Solution Approach 1:
The patent combines multiple fiber optic cables into a single integrated distribution device (floor box) that serves multiple subscribers. Instead of having separate cables routed through walls for each subscriber, the device consolidates multiple cable entries and distribution points in one location, reducing overall system complexity while maintaining individual connection reliability for each subscriber.
Solution Approach 2:
The floor box device performs multiple functions: it serves as a cable entry point, a distribution hub for multiple subscribers, a splicing location, and a mounting point for network terminals. This multi-functional design eliminates the need for separate devices for each function, reducing installation complexity while ensuring reliable connections.
2Manufacturing precision
If skilled technicians are used for installation, then installation quality is improved, but installation cost increases
Solution Approach 1:
The distribution device is divided into modular components including removable wall sections, grommets for cable protection, splice trays for fiber splicing, and mounting mechanisms. This segmentation allows for easier assembly and installation by less skilled technicians while maintaining installation quality through standardized, pre-configured components.
Solution Approach 2:
The device is pre-configured with wall sections, grommets, and splice trays during manufacturing. This preliminary preparation eliminates the need for complex on-site configurations, allowing faster installation by technicians with less specialized training while maintaining consistent installation quality.
3Adaptability or versatility
If extensive cabling through walls and building levels is implemented, then network coverage is improved, but installation time increases
Solution Approach 1:
The floor box device consolidates cable management in a horizontal plane at the floor level, eliminating the need for vertical cable routing through walls and building levels. By providing multiple cable entry points and distribution outlets in a single floor-mounted unit, the device achieves wide network coverage without time-consuming vertical installations.
