Optical Network Termination Device with Visible External Identifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network termination devices for optical networks often result in unnecessary costs and space consumption due to separate housings for the base unit and network termination terminal, making it complex and costly to activate or release desired services for end users.
Innovation Solution
A network termination device with a base unit featuring an external identifier that remains visible and accessible, allowing easy recognition and activation of services without removing the network termination terminal, and a cover design that prevents dust penetration and facilitates easy connection of cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the base unit and network termination terminal are housed in two separate enclosures, then the network termination device can be flexibly configured with different modules, but this results in unnecessary costs and additional space requirements
Solution Approach 1:
The patent combines the base unit and network termination terminal into a single integrated housing structure. The terminal is received within the same enclosure as the base unit, eliminating the need for separate stacked boxes. This merging reduces structural complexity and space requirements while maintaining the modular functionality of the terminal modules within the unified housing.
2Loss of information
If the identifier is positioned on the base unit, then it provides unique identification for service activation, but it may be obscured by the attached network termination terminal
Solution Approach 1:
The patent positions the identifier on the cover rather than on the base unit. The cover is transparent or translucent, allowing the identifier to be visible from above through the cover material. This dimensional relocation to the cover surface, combined with transparency, ensures the identifier remains accessible for service activation while the terminal is attached to the base unit below.
Solution Approach 2:
The transparent or translucent cover acts as an intermediary element between the identifier on the base unit and the external environment. It allows optical transmission of the identifier information while providing physical protection and structural closure for the housing, enabling visibility without direct exposure.
3Object-affected harmful factors
If a cover is added to seal the base unit, then dust penetration is prevented, but the identifier must remain visible through the cover design
Solution Approach 1:
The patent employs a transparent or translucent cover made of a material that allows optical transmission. This thin film-like cover provides dust sealing and protection while maintaining visibility of the identifier through its transparent or translucent properties, reconciling the conflicting requirements of protection and visibility.
