Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing USB type-C receptacle connectors can only accommodate a single plug connector for signal transmission, limiting their ability to meet the increasing demand for higher bus bandwidth and performance in interactive devices.
Innovation Solution
The design of an electrical receptacle connector with a metallic shell, insulated housing, and dual groups of terminals, allowing for two insertion openings and 180-degree symmetrical dual orientation, enabling the connection of two plug connectors and supporting USB 3.0 or USB 3.1 interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single plug opening is provided in the existing USB type-C receptacle connector, then the structure is simple, but the connector cannot accommodate multiple plug connectors for signal transmission
Solution Approach 1:
The connector is divided into an upper tongue portion and a lower tongue portion, each capable of accommodating a plug connector. The partition plate separates these two portions, allowing independent insertion openings while maintaining structural organization. This segmentation enables the connector to accommodate multiple plug connectors without creating a completely complex new structure.
Solution Approach 2:
The invention transitions from a single-plane insertion opening to a multi-plane configuration by stacking the upper and lower tongue portions vertically. This dimensional change allows multiple insertion openings to be provided without significantly increasing the horizontal footprint, thus accommodating multiple plug connectors while controlling overall complexity.
2Manufacturing precision
If multiple terminals are arranged in a single plane, then the layout is simple, but the manufacturing precision requirements increase
Solution Approach 1:
The terminals are segmented into first terminals in the upper tongue portion and second terminals in the lower tongue portion. Each terminal group is arranged in its own dedicated space, which simplifies the manufacturing precision requirements for each individual group while allowing the overall connector to achieve high precision through modular assembly.
Solution Approach 2:
The terminal arrangement transitions from a single-plane layout to a multi-layer stacked configuration. This dimensional change distributes terminals across different vertical levels, reducing the precision requirements for planar positioning while maintaining overall connector precision through the structured stacking of tongue portions.
3Quantity of substance
If a single insertion opening is provided, then the material usage is reduced, but the bandwidth capacity is limited
Solution Approach 1:
The connector is segmented into upper and lower functional portions, each with its own insertion opening and terminal group. This segmentation allows the connector to support multiple simultaneous connections and aggregate bandwidth capacity while using materials efficiently through shared structural elements like the partition plate and housing.
Solution Approach 2:
The connector capacity expands from a single insertion opening to multiple insertion openings arranged in the vertical dimension. This dimensional expansion increases bandwidth capacity and connectivity options without proportionally increasing material usage, as the stacked structure shares common housing and support elements.

AI summary
An electrical receptacle connector includes a metallic shell, an insulated housing, first and second groups of terminals, an adapting circuit board, and extension terminals. The insulated housing is received in the metallic shell and includes a base portion, upper and lower tongue portions, and a partition plate. Upper and lower plug openings are respectively formed between the partition plate and the upper portion of the metallic shell and between the partition plate and the lower portion of the metallic shell. The terminals are held in the insulated housing. The adapting circuit board is disposed at the rear of the insulated housing and includes an upper-row contact set connected to the first group of terminals and a lower-row contact set. One ends of the extension terminals are connected to the lower-row contact set, and the other ends of the extension terminals are extended to the bottom of the insulated housing.
