Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fiber optic adapters lack efficient alignment and secure attachment mechanisms for ferrule-based connectors, leading to potential misalignment and instability during connection and disconnection processes.
Innovation Solution
The design incorporates two adapter halves with integrally molded ferrule alignment structures and cantilevered retaining clips that elastically deform to securely latch into apertures, ensuring coaxial alignment and stable attachment of optical fiber connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional separate components are used for alignment and retention, then manufacturing flexibility is maintained, but assembly complexity increases and alignment precision deteriorates
Solution Approach 1:
The patent combines ferrule alignment structures and retaining clips into a single integrally molded component. The alignment structures include ferrule positioning features and the retaining clips are formed as one piece, eliminating the need for separate alignment and retention components. This integration ensures precise ferrule alignment while reducing assembly steps and component count.
Solution Approach 2:
The integrally molded structure performs multiple functions simultaneously: it provides ferrule alignment through positioning features, secures the connector through retaining clips, and maintains structural integrity as a single component. This multi-functional design reduces the number of parts needed while achieving both alignment precision and secure attachment.
2Reliability
If rigid retention structures are used, then secure attachment is achieved, but adaptability to different aperture sizes is reduced
Solution Approach 1:
The retaining clips are designed with elastic deformation capability, allowing them to flex dynamically to accommodate different aperture sizes. The clips can elastically deform during installation to fit various panel aperture dimensions and then maintain secure attachment through their elastic recovery, providing both adaptability and reliable retention.
Solution Approach 2:
The retaining clips utilize elastic parameter changes to adapt to different aperture sizes. By changing their physical state through elastic deformation, the clips can accommodate varying aperture dimensions while maintaining secure attachment. This elastic parameter change allows the same component to work with multiple aperture sizes without compromising retention reliability.
3Ease of manufacture
If multiple separate components are used for alignment and retention, then design flexibility is maintained, but manufacturing efficiency decreases
Solution Approach 1:
The patent integrates multiple functions into a single moldable component, combining ferrule alignment features and retaining clips into one integrally molded part. This eliminates the need for separate manufacturing and assembly steps for alignment and retention components, significantly improving manufacturing efficiency while reducing assembly complexity.
Solution Approach 2:
The integrally molded structure is pre-formed with all necessary alignment and retention features during the single molding process. The ferrule positioning features and retaining clips are created in advance as part of the same manufacturing operation, eliminating subsequent assembly steps and improving overall manufacturing efficiency.

AI summary
The present disclosure relates to a fiber optic adapter for interconnecting first and second optical fiber connectors in coaxial alignment along an optical axis. The fiber optic adapter includes a housing with a first end and an opposite, a second end. The housing includes first and second adapter halves that each include an axial cavity defined by a top side-wall, a bottom side-wall, a right side-wall, and a left side-wall. The fiber optic adapter includes a first ferrule alignment structure located within the axial cavity of the first adapter half of the housing and a second ferrule alignment structure located within the axial cavity of the second adapter half of the housing. The fiber optic adapter includes double cantilever wings respectively positioned on the right and left side-walls of each one of the first and second adapter halves of the housing. The double cantilever wings are slotted to provide dual arm clips configured to elastically deform for attachment into an aperture defined by a bulkhead structure.
