USB-C Connector Orientation Switching for Host and Console Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional USB Type-C connectors lack the ability to function in both host and device modes without requiring a switching mechanism, limiting their versatility and space efficiency on devices with limited connector space.
Innovation Solution
A USB Type-C connector design that allows insertion in two orientations, enabling operation in either a master mode or slave mode without the need for a multiplexer, using orientation-dependent circuitry and LEDs to indicate the mode, and incorporating a master and slave unit for data transfer and power supply/reception.

Engineering Contradiction Analysis
1Area of stationary object
If a single USB-C connector is used for both host and device modes, then space requirements and costs are reduced, but the connector cannot function in both modes without a switching mechanism
Solution Approach 1:
The connector is segmented into two distinct operational modes (host mode and device mode) that are activated based on insertion orientation. The port circuitry is divided into a master unit for host mode and a slave unit for device mode, with each unit independently configured to handle specific data and power operations appropriate to its mode
Solution Approach 2:
The connector utilizes asymmetric internal circuitry routing where the same physical connector structure supports different functional configurations based on orientation. The master and slave units are asymmetrically designed to activate different operational pathways depending on which orientation the plug is inserted
2Adaptability or versatility
If separate ports are used for data and console functions, then dual functionality is achieved, but space requirements and device complexity increase
Solution Approach 1:
The patent merges two separate functional ports (data port and console port) into a single USB-C connector. The master unit handles data port functions while the slave unit handles console port functions, allowing both functionalities to coexist in one physical connector through orientation-based mode selection
Solution Approach 2:
The single USB-C connector is designed with universal functionality to serve multiple purposes: it can operate as a data port in host mode, as a console port in device mode, or support both functions sequentially based on insertion orientation, eliminating the need for dedicated separate ports
3Adaptability or versatility
If a multiplexer is added to enable mode switching, then dual mode operation is possible, but device complexity and cost increase
Solution Approach 1:
The connector automatically determines the appropriate operational mode based on the physical insertion orientation of the plug. The port circuitry self-configures by detecting orientation and activating either the master unit or slave unit without requiring external control signals or complex switching logic

AI summary
Systems and methods for enabling dual functionality of a connector are provided. According to one implementation, port circuitry may be associated with a receptacle of an electrical connector configured for connection with a compatible plug. The port circuitry may include a master unit configured to one or more of transfer data to and supply power to the compatible plug when the compatible plug is inserted into the receptacle in a first orientation. Also, the port circuitry may include a slave unit configured to one or more of transfer data from and receive power from the compatible plug when the compatible plug is inserted into the receptacle in a second orientation.
