USB-C Interface Adapter for Simultaneous Audio and Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with a single USB type-C connector cannot simultaneously connect to both an audio device and a charger, preventing users from charging the device while listening to music.
Innovation Solution
An interface device with a USB type-C plug, receptacle, and an analog audio jack, along with a connection circuit that allows the device to connect to either an audio device or a charger, and enables quick charging when connected to a charger but not an audio device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an electronic device uses a single USB type-C connector, then the device structure is simplified and modern connectivity is achieved, but the device cannot simultaneously connect to both an audio device and a charger
Solution Approach 1:
The interface device segments the USB type-C connector functionality into two separate receptacles: one for audio device connection and one for charger connection. This allows the single USB type-C plug to be selectively connected to different receptacles, enabling simultaneous connectivity to both audio devices and chargers while maintaining the simplified modern connector structure.
Solution Approach 2:
The interface device acts as an intermediary adapter between the USB type-C connector and traditional connectors. It includes a USB type-C plug that connects to the electronic device, and provides both an audio jack receptacle and a charger receptacle, mediating between the modern single connector and the need for multiple simultaneous connections.
2Ease of operation
If the USB type-C connector is used for audio device connection, then audio functionality is achieved, but the device cannot be charged simultaneously
Solution Approach 1:
The interface device separates the audio connection function and charging function into distinct receptacles. The USB type-C plug can be connected to the audio receptacle for audio playback, or to the charger receptacle for charging, or both simultaneously depending on the configuration, allowing independent optimization of each function.
3Productivity
If quick charging is enabled when only charger is connected, then charging speed is improved, but the system becomes more complex in managing connection states
Solution Approach 1:
The interface device includes a detection circuit that monitors the connection state of both receptacles and provides feedback to control the charging voltage. When only the charger receptacle is connected (audio receptacle empty), the system detects this state and enables quick charging with higher voltage. When both are connected, it switches to standard charging voltage, automatically adapting to the connection configuration.

AI summary
Disclosed is an interface device capable of simultaneously connecting an audio device and charger to an electronic device. An interface device may enable an electronic device with a single USB type-C connector but no analog audio jack to connect to both an audio device and a charger through the USB type-C connector. The interface device may provide automated quick charging when connected with the charger but not with the audio device.
