Optical Termination Box Recessed Adapter Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical termination boxes are too thick due to the placement of optical adapters on the bottom wall, which prevents them from being reduced in size, and current solutions do not effectively address the need for thinner designs suitable for installation in thin spaces like power sockets.
Innovation Solution
The optical termination box design features a recess in the bottom wall to support the back portion of the optical adapter, with the front portion protruding and partially housed in a bottom opening, allowing the cover to be attached without increasing the overall thickness, and includes a support frame for easy installation without removing the cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If optical adapters are placed on the bottom wall of the base, then the optical termination box can host optical adapters, but the overall thickness increases and cannot be reduced
Solution Approach 1:
The optical adapter is repositioned from a conventional bottom-wall mounting to a side-wall mounting arrangement. The adapter protrudes through the side wall of the base, with its back portion supported by a recess in the bottom wall and its front portion extending outward. This dimensional repositioning allows the adapter to be hosted while minimizing the thickness along the vertical axis, enabling the overall thickness to be reduced to the sum of the adapter height and cover height.
2Volume of moving object
If the optical termination box is made thinner to match power socket thickness, then it meets user demand for compact installation, but it becomes difficult to provide adequate support and protection for optical components
Solution Approach 1:
The optical adapter is nested within a specially designed structural arrangement comprising a recess in the bottom wall and a support frame attached to the inner surface of the bottom wall. The recess receives and supports the back portion of the adapter, while the support frame provides additional structural reinforcement and protection. This nested configuration allows the adapter to be securely housed within the thin profile of the termination box without compromising reliability.
3Reliability
If a support frame is added to provide structural support for the thin design, then reliability is improved, but device complexity increases
Solution Approach 1:
The support frame is merged with the base structure by attaching it to the inner surface of the bottom wall, creating an integrated support system. The frame is positioned to align with the recess and work in conjunction with it, combining multiple support functions into a single integrated component rather than separate elements. This merging approach provides the necessary structural reinforcement for the thin design while minimizing the increase in device complexity.
