Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic connector systems require adapters for mating, which can lead to inefficiencies and increased complexity in data center applications, particularly in high-density backplane and PCB systems, where reliable and adapter-free connections are needed for optical fibers.
Innovation Solution
A data center connector system comprising a receptacle and plug assembly with a movable ferrule mechanism, where the receptacle ferrule is biased towards the plug receiving end, allowing for direct and reliable connection of optical fibers without adapters, utilizing a rectangular cross-section design with latch ports and arms for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adapters are used for mating fiber optic connectors, then alignment and connection reliability are improved, but device complexity and system inefficiency increase
Solution Approach 1:
The patent removes the adapter component from the fiber optic connection system. The plug and receptacle connectors are designed to mate directly with each other without requiring an intermediate adapter, thereby eliminating the extra part while maintaining alignment and connection reliability through precision-fitted mating surfaces and ferrule alignment features
Solution Approach 2:
The patent combines the alignment and connection functions that were previously distributed between the connector and adapter into a single direct mating interface. The plug and receptacle are designed with integrated alignment features (such as keyed entrances and latch mechanisms) that perform both alignment and securement in one component interface, reducing overall system complexity
2Measurement precision
If adapters are used for connector mating, then alignment precision is improved, but productivity and operational efficiency deteriorate
Solution Approach 1:
The patent segments the connection system into distinct plug and receptacle components with precisely defined mating interfaces. Each component has specific alignment features (keyed entrances, ferrule positioning) that work together to achieve precise alignment without requiring an adapter, enabling quick and accurate connector mating
Solution Approach 2:
The plug and receptacle are pre-configured with alignment features and geometric constraints during manufacturing. The keyed entrance and ferrule positioning structures are built-in from the start, eliminating the need for additional alignment steps or adapters during installation, thereby improving operational efficiency
3Reliability
If a movable ferrule mechanism with biasing is used, then connection reliability and signal quality are improved, but manufacturing complexity increases
Solution Approach 1:
The patent incorporates a movable ferrule mechanism within the receptacle that can move axially to accommodate insertion and maintain optimal contact. A spring provides biasing force to ensure consistent ferrule-to-ferrule contact pressure, improving connection reliability and signal quality while using a well-established mechanical mechanism that balances performance with manufacturability

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables reliable, adapter-free connections that minimize optical signal attenuation and facilitate moves, adds, and changes in data center systems, ensuring efficient fiber optic interconnections with reduced complexity.
Implementation Method 1
A spring is received by a spring retainer body. The spring is compressed between the spring retainer body and the receptacle ferrule.

AI summary
A data center connector (DCC) system includes a receptacle connector assembly that includes a receptacle body having a plug receiving end, a panel assertion end and a plug receiving chamber at the plug receiving end that receives a plug body of a plug connector assembly. A receptacle ferrule is located in the receptacle body. The receptacle ferrule is moveable axially within the receptacle body and biased toward the plug receiving end. A plug connector assembly includes a plug body having an insertion end sized to be received within the plug receiving chamber of the receptacle body. A plug ferrule is fixed axially within the plug body that contacts the receptacle ferrule and moves the receptacle ferrule axially with the plug body being inserted within the plug receiving chamber of the receptacle body.
