Multiport Assemblies with Sealing Piston Securing Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multiport assemblies for optical fiber connectors lack robustness and security, leading to potential signal disruption due to inadvertent or unauthorized manipulation of sealing piston securing members.
Innovation Solution
A multiport assembly design that includes a shell with apertures smaller than a human finger, requiring a release tool for access, and sealing piston securing members that can be selectively engaged or disengaged to secure or release optical connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sealing piston securing members are made accessible for easy release, then ease of operation is improved, but reliability deteriorates due to inadvertent or unauthorized manipulation
Solution Approach 1:
A release tool serves as an intermediary device between the user and the sealing piston securing member. The release tool is inserted through an aperture to engage and depress the button portion of the sealing piston securing member, enabling controlled release of optical connectors. This intermediary mechanism prevents direct access to the securing member, thereby eliminating inadvertent or unauthorized manipulation while maintaining ease of operation when the proper tool is available.
2Ease of operation
If apertures are made larger for tool access, then ease of operation is improved, but security deteriorates as fingers can access sealing piston securing members
Solution Approach 1:
The aperture is designed with specific dimensional characteristics that allow passage of the release tool while preventing insertion of fingers. The aperture width is greater than the width of the release tool, enabling tool access, but smaller than the width of a finger, blocking direct manual access to the sealing piston securing member. This local quality differentiation creates a selective access mechanism that maintains security while enabling operational functionality.
3Reliability
If sealing piston securing members are made robust and secure, then reliability is improved, but ease of operation worsens due to difficulty in release
Solution Approach 1:
The sealing piston securing member incorporates a button portion that can be depressed by the release tool to transition from an engaged state to a disengaged state. This dynamic mechanism allows the securing member to maintain a secure, locked position during normal operation while enabling controlled release when the button is actuated by the proper tool. The spring mechanism provides dynamic response, automatically returning the securing member to its engaged position after release.

AI summary
A multiport assembly includes a shell defining a cavity, a plurality of apertures extending through the shell to the cavity, and a plurality of optical connector ports defining connector insertion paths, a plurality of optical adapter assemblies positioned within the cavity of the shell, and a plurality of sealing piston securing members associated with respective ones of the connector insertion paths, where each of the sealing piston securing members is repositionable between an engaged position, in which at least a portion of the sealing piston securing member intersects the connector insertion path, and a disengaged position, in which a securing portion of the sealing piston securing member is spaced apart from the connector insertion path, and where a width of a button portion of each of the sealing piston securing members is greater than width defined by each of the plurality of apertures.
