Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a composite electronic connector updates from USB Type-A to USB Type-C connector combination, then the connector interface capability is improved, but the mainboard circuit design complexity and development cost increase significantly
Solution Approach 1:
The patent introduces a composite electronic connector as an intermediary device that bridges USB Type-C and USB Type-A interfaces. This connector contains a USB Type-C connector, circuit board with signal conversion circuitry, and USB Type-A connector integrated together. The signal conversion circuitry acts as a mediator that converts USB Type-C signals to USB Type-A signals, allowing the mainboard to use existing USB Type-A interfaces while gaining USB Type-C functionality through the external connector assembly.
2Adaptability or versatility
If a composite electronic connector updates from USB Type-A to USB Type-C connector combination, then the connector interface capability is improved, but the development and manufacturing cost of the mainboard increases
Solution Approach 1:
The composite electronic connector serves as a cost-effective intermediary solution. Instead of requiring expensive mainboard redesigns, the patent places the USB Type-C interface and signal conversion circuitry in an external connector assembly that can be manufactured separately and attached to the mainboard. This approach allows manufacturers to upgrade interface capabilities without incurring high development and manufacturing costs for the mainboard itself.
3Adaptability or versatility
If the mainboard uses a USB Type-C connector directly, then the USB Type-C functionality is achieved, but the existing USB Type-A inserting holes and circuit arrangement cannot be utilized
Solution Approach 1:
The patent merges USB Type-C and USB Type-A connectors into a single integrated composite electronic connector assembly. The circuit board within this assembly integrates signal conversion circuitry that combines both connector types, allowing the mainboard to use existing USB Type-A inserting holes and circuit arrangements while simultaneously providing USB Type-C functionality through the integrated USB Type-C connector portion of the assembly.

AI summary
A composite electronic connector comprising an insulating housing, a USB Type-C connector and a USB Type-A connector which are arranged in the insulating housing is disclosed. The USB Type-C connector comprises a circuit board, a connecting line and a plurality of transferring terminals. One side of the circuit board is arranged with twenty-four golden fingers, other side of the circuit board is connected with the plurality of transferring terminals. The connecting line is used to integrate signal transmitted through the twenty-four golden fingers of the USB Type-C connector into USB Type-A standard adopted outputting signal, and outputs the outputting signal through the plurality of transferring terminals.
