Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network interface connectors face challenges in modifying transmission characteristics after being soldered to a motherboard, requiring costly and inconvenient replacement when specific performance parameters are not met, as they are designed for specific PHYs and cannot accommodate varying transmission requirements across different applications.
Innovation Solution
A modular network interface connector design featuring a contact assembly with a proximity insert that can be easily swapped between the rearward portions of elongate contacts, allowing for adjustment of transmission properties without de-soldering from the motherboard, using materials like BaTio2, ceramics, or ferrite to achieve desired electrical characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connectors are designed for specific PHYs with fixed transmission characteristics, then transmission performance for specific applications is optimized, but adaptability to different transmission requirements across various applications is lost
Solution Approach 1:
The connector is divided into separate functional modules: a base connector unit and interchangeable proximity compensation modules. Each module can be independently designed and optimized for specific transmission requirements, allowing the system to maintain optimized performance for each application while enabling easy reconfiguration for different PHYs and transmission standards.
Solution Approach 2:
The base connector unit is designed with universal compatibility to work with multiple PHY types and transmission standards. By incorporating interchangeable proximity compensation modules with different electrical characteristics (such as different dielectric materials like BaTio2, ceramics, or ferrite), a single connector design can serve multiple applications including 10/100 MbE, 1 GbE, and 10 GbE networks.
2Reliability
If connectors are customized for specific transmission parameters, then transmission characteristics are optimized for specific applications, but the cost and complexity of replacing entire connectors increases when performance requirements change
Solution Approach 1:
The connector system is segmented into a permanent base unit and replaceable proximity compensation modules. When transmission requirements change, only the small proximity module needs to be replaced rather than the entire connector, significantly reducing material costs, manufacturing complexity, and installation time.
Solution Approach 2:
The design allows for easy replacement of proximity compensation modules that have fulfilled their specific transmission optimization function. These modules can be removed and discarded or recovered, while the base connector unit remains in use, reducing waste and installation costs compared to replacing entire connectors.
3Stability of the object's composition
If connectors are soldered to motherboards with fixed transmission properties, then installation stability is ensured, but the ability to modify transmission characteristics after installation is lost
Solution Approach 1:
The connector is segmented such that the base unit is permanently soldered to the motherboard for stable installation, while the proximity compensation module remains a separate, interchangeable component. This allows the soldered connection to provide mechanical stability and electrical connectivity, while the removable module enables post-installation modification of transmission characteristics by simply plugging in different modules.
Solution Approach 2:
The system transitions from a static, fixed connector design to a dynamic configuration where the proximity compensation module can be changed after installation. This dynamic capability allows the transmission characteristics to be adapted to different PHYs and applications without requiring re-soldering or permanent modification of the motherboard connection.

Function Achieved in This Case
Enables flexible modification of transmission characteristics in situ, reducing costs and installation disruptions by allowing customization of connectors for different applications without replacing the entire network installation, while maintaining compliance with standards like TIA 568A and IEC 60603-7.
Implementation Method 1
The first and second elongate contacts have rearward portions that are situated in first and second spaced parallel planes respectively to define a proximity gap between them. A proximity insert is situated, preferably removably, in the proximity gap between the rearward portions of the first and second elongate contacts.

AI summary
A network interface connector includes a plurality of first and second alternating elongate contacts having contact portions situated in a common plane. The first and second contacts have rearward portions situated in respective first and second spaced parallel planes defining a proximity gap between them. A proximity insert having a particular electrical construction suited for a particular application is situated, preferably in a replaceable manner, in the proximity gap to provide the connector with desired transmission properties.
