USB Charging Device with Dynamic Profile Update via Extra Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery charging devices using USB 2.0 standards struggle to support new electronic devices with different charging profiles, as they rely on fixed voltage combinations on the D+ and D− terminals, limiting their ability to adapt to new charging currents.
Innovation Solution
The introduction of an electronic assembly with a USB 2.0 Type A connector that is physically compliant but operationally non-compliant with USB 3.0 standards, allowing for the use of additional terminals to receive and update charging profile data, enabling support for new charging profiles through a USB 3.0 connector and a data cable or wireless transceiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If USB 2.0 standard connectors are used with fixed voltage combinations on D+ and D- terminals, then compatibility with existing USB devices is maintained, but the ability to support new charging profiles with different charging currents is limited
Solution Approach 1:
The USB connector is designed to serve multiple functions: standard USB 2.0 data transmission and charging, and updated USB 3.0 compliant charging profile configuration. The single connector handles both legacy devices and new devices requiring updated charging profiles, eliminating the need for separate connectors or disassembly operations.
Solution Approach 2:
The connector configuration is made dynamic by enabling remote reconfiguration of the charging profiles stored in the controller's memory. The system can adapt its charging behavior in real-time based on device identification and can be remotely updated via USB connection to support new charging standards without physical modification.
2Adaptability or versatility
If a custom connector or disassembly is required to update charging profile data, then new charging profiles can be supported, but the ease of operation and manufacturing cost increase
Solution Approach 1:
The system performs self-updating of charging profiles through automated detection and configuration. When a new device is connected, the controller automatically identifies the device type, determines the appropriate charging profile, and configures the USB connector parameters without requiring user intervention, custom connectors, or disassembly operations.
Solution Approach 2:
The existing USB connector is made multi-functional to handle both standard USB operations and updated charging profile configurations. The same physical connector and data lines are used for both device communication and charging profile updates, eliminating the need for separate update mechanisms or custom connectors.
3Adaptability or versatility
If additional terminals or connections are added to support USB 3.0 standards, then new charging profiles can be received, but the device complexity and cable requirements increase
Solution Approach 1:
The USB 3.0 connector is designed with additional terminals that serve multiple purposes: they can support future high-speed data transmission requirements and simultaneously provide dedicated data lines for charging profile updates. The same additional terminals are used for both potential data communication and charging configuration, maximizing utility while minimizing complexity.
Solution Approach 2:
The USB data lines (D+ and D-) serve as intermediaries for transmitting charging profile information. Rather than requiring separate dedicated terminals for profile updates, the existing data communication channels are utilized to convey charging configuration data, reducing the need for additional physical connections.

AI summary
An electronic assembly including a first connector having a first set of terminals physically and operationally compliant with a data transmission connector standard, such as USB 2.0, and a second set of terminals distinct from the first set of terminals physically compliant and operationally non-compliant with this data transmission connector standard. An electronic controller is connected to the first connector. The controller includes a memory device to store configuration data, such as a battery charging profile, used by the controller to control a first electronic device, such as a battery charging device. The second set of terminals receive new configuration data to update the configuration data stored in the memory device. The assembly may include a specially configured data cable to interconnect the assembly to a separate electronic device to transmit the updated configuration data. The assembly may reduce the current supplied for battery charging by monitoring a battery voltage.
