Optical Termination Box Hinged Panel Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In old buildings or brownfield sites, there is a need for compact optical distribution boxes that can fit in narrow spaces without compromising the transmission capability of optical fibers, while also providing access to all necessary areas within the box.
Innovation Solution
The optical termination box design features separate and overlapping surfaces for connection and storage areas, allowing for a significant reduction in size by defining these areas on opposite surfaces of a hinged panel, which can rotate between closed and open positions, thus minimizing the overall dimensions without bending optical fibers below a minimum radius.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the optical termination box is made compact to fit in narrow spaces, then the installation space requirement is reduced, but the access to connection and storage areas becomes difficult
Solution Approach 1:
The patent employs a hinged panel that can rotate between closed and open positions, transforming the static box structure into a dynamic system. When opened, the panel provides access to connection areas on one surface and storage areas on the other, solving the contradiction between compact size and operational accessibility.
Solution Approach 2:
The patent utilizes three-dimensional space by defining connection and storage areas on opposite surfaces of the hinged panel. This vertical stacking of functional areas on different surfaces allows compact footprint while maintaining full accessibility when the panel is opened.
2Area of stationary object
If the optical termination box is made compact, then the installation space is reduced, but the optical fibers may be bent below minimum radius
Solution Approach 1:
The rotatable hinged panel creates dynamic space management that allows the box to maintain compact dimensions when closed while providing sufficient internal volume and fiber routing space when opened, preventing excessive fiber bending.
Solution Approach 2:
By distributing functional areas on opposite surfaces of the hinged panel, the patent creates adequate three-dimensional space for fiber routing and storage without increasing the box's external footprint, thus maintaining minimum bending radius requirements.
3Area of stationary object
If separate surfaces are used for connection and storage areas, then the box size is reduced, but the structural complexity increases
Solution Approach 1:
The patent divides the box interior into distinct functional zones on opposite surfaces of the hinged panel - connection areas on one surface and storage areas on the other. This segmentation allows compact packaging while maintaining clear functional separation.
Solution Approach 2:
The hinged panel itself serves multiple functions: it acts as a structural element, a door for access, and a surface for mounting both connection and storage areas. This merging of functions reduces overall structural complexity despite the multi-surface layout.

AI summary
An optical termination box (1), comprising a base body (10) and a cover removably attached to the base body (10). The base body (10) comprises a connection area (70) comprising connector supporting frames (71) configured to house adapters (72) for connecting input pre-connectorized optical fibers connected to an optical cable entering into the optical termination box (1) to output pre-connectorized optical fibers exiting from the optical termination box (1). The base body (10) further comprises a storage area for parking extra-length portions of the input pre-connectorized optical fibers and extra-length portions of the output pre-connectorized optical fibers. The connection area (70) and the storage area are defined on separate, overlapped surfaces (20a, 20b), which can be on opposite surfaces (20a,20b) of a panel (20) hinged to the base body (10).
