Electrical Connector with Nested USB Ports for High-Speed Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited data transmission speed of USB 2.0 connectors is insufficient for high-speed signal transmission between peripheral devices, necessitating the design of electrical connectors with additional mating ports for enhanced data transfer capabilities.
Innovation Solution
The electrical connector features an insulative housing with parallel tongue portions, non-elastic and elastic contacts, and a metal shield, allowing for dual receiving cavities to accommodate standard USB plugs while providing an additional port for high-speed signal transmission, enabling improved bandwidth through the combination of standard and expanded insertion connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If USB 2.0 connectors are used, then compatibility with existing devices is maintained, but data transmission speed is limited to 480 Mbit/s
Solution Approach 1:
The patent implements a nested connector design where a first connector (USB 2.0 standard) is embedded within a second connector (high-speed interface). The first connector housing contains the second connector, allowing both interfaces to coexist in a single physical component. This enables high-speed data transmission through the nested second connector while maintaining compatibility with existing USB 2.0 devices through the outer first connector, effectively resolving the speed-compatibility contradiction.
Solution Approach 2:
The connector is segmented into two distinct functional parts: a first connector for standard USB 2.0 communication and a second connector for high-speed data transmission. Each segment handles specific data rate requirements independently, allowing the system to optimize for speed when needed while preserving backward compatibility through the separate first connector segment.
2Productivity
If a single USB connector is used, then device simplicity is maintained, but additional high-speed transmission capability cannot be added
Solution Approach 1:
By nesting the second high-speed connector within the first USB 2.0 connector housing, the patent achieves high productivity (data transfer rate) without proportionally increasing device complexity. The nested structure allows both connectors to share the same physical space and mounting interface, so while the internal structure is more complex, the external form factor and installation requirements remain relatively simple.
Solution Approach 2:
The combined connector structure serves multiple functions simultaneously: it provides standard USB 2.0 connectivity for compatibility, high-speed data transmission capability for enhanced productivity, and a unified mounting interface for simple installation. This multi-functionality approach allows the single connector assembly to deliver both high performance and ease of deployment.

AI summary
An electrical connector includes an electrical receptacle and an electrical plug for mating with the electrical receptacle. The electrical receptacle includes a first port, a second port communicating with the first port. The second port can accommodate a standard B-type USB 2.0 plug. The first and the second ports can be combined to receive the electrical plug for high-speed signal transmission.
