Receptacle Connector with Segmented USB 2.0 and 3.0 Pins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing USB interfaces, such as USB 2.0, face limitations in transmission efficiency as computers process larger data volumes, necessitating the development of USB 3.0 with higher transmission rates and lower power consumption.
Innovation Solution
A receptacle connector is designed to comply with both USB 2.0 and USB 3.0 specifications, featuring an insulated housing with specific contact pin configurations and a metal casing, ensuring stable high-rate data transmission by incorporating five first contact pins for USB 3.0 and four second contact pins for USB 2.0 standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If USB 2.0 interface is used, then compatibility and ease of manufacture are maintained, but transmission rate and data transfer capability are limited
Solution Approach 1:
The receptacle connector is segmented into two distinct contact pin groups: five first contact pins for USB 3.0 high-speed data transmission and four second contact pins for USB 2.0 compatibility. This segmentation allows the device to support multiple transmission rates while maintaining a unified connector structure, resolving the contradiction between high speed and complexity.
Solution Approach 2:
The receptacle connector is designed with multi-functionality to support both USB 2.0 and USB 3.0 interfaces simultaneously. By incorporating contact pins that comply with both standards, the connector can adapt to different transmission rate requirements without requiring separate connectors, thus improving transmission rate capability while managing device complexity.
2Productivity
If USB 3.0 interface is implemented, then data transfer capability and transmission efficiency are improved, but device complexity increases
Solution Approach 1:
The contact pin configuration is segmented into five first contact pins for USB 3.0 high-speed data transfer and four second contact pins for USB 2.0 compatibility. This segmentation enables the connector to achieve high data transfer capability while organizing the complexity into manageable, standardized groups that follow USB specification requirements.
Solution Approach 2:
The connector design adds a dimensional aspect by incorporating contact pins from both USB 2.0 and USB 3.0 standards within the same receptacle structure. This multi-dimensional approach allows the connector to handle both legacy and high-speed data transfer requirements simultaneously, improving productivity while distributing complexity across different functional dimensions.
