Engineering Contradiction Analysis
1Speed
If a USB Type-C interface is used in an electronic device, then the data transmission rate and modern interface capabilities are improved, but compatibility with legacy USB 2.0 systems is lost due to different pin configurations and signal types
Solution Approach 1:
A gender adapter is introduced as an intermediary device between the USB Type-C interface and legacy USB 2.0 systems. The adapter includes a Type-C connector on one end and a USB 2.0 connector on the other, with internal circuitry that converts digital signals from the Type-C interface into analog signals compatible with legacy USB 2.0 devices, thereby enabling communication between incompatible interfaces
Solution Approach 2:
The patent changes the signal parameters by converting digital ID information from the USB Type-C interface into analog ID information that legacy USB 2.0 systems can recognize. This parameter transformation allows the electronic device to maintain modern digital interface capabilities while accommodating older analog-based systems through the gender adapter
2Ease of operation
If a gender adapter is used to connect USB Type-C and USB 2.0 interfaces, then physical connection is enabled, but USB ID recognition fails because legacy systems transmit analog signals while USB Type-C uses digital signals only
Solution Approach 1:
The gender adapter serves as a signal conversion intermediary that receives digital ID information from the USB Type-C interface through its digital connector, processes the signal, and outputs analog ID information through its USB 2.0 connector. This mediation enables legacy systems to recognize device IDs that would otherwise be invisible due to signal type incompatibility
Solution Approach 2:
The adapter performs parameter transformation by converting digital signal characteristics into analog signal characteristics. Specifically, it transforms digital ID information into analog ID information with appropriate voltage levels and signal formats that match legacy USB 2.0 expectations, preventing information loss during the connection
