Dual USB Port Exclusive Structure Circuit Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses require multiple sets of circuits to accommodate different USB standards, leading to complex configurations and increased costs.
Innovation Solution
An electronic apparatus with a dual USB Type C and USB Type A connection system, where a single set of internal circuits can handle both standards through a branching wire structure and a wire switching circuit, allowing only one standard to be used at a time by physically preventing the connection of the other standard's connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sets of circuits are configured to support different USB standards, then compatibility with various USB standards is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal USB connection system where a single set of circuits can handle both USB Type-C and USB Type-A standards. The connection ports are designed with overlapping configurations where the USB Type-C port and USB Type-A port share the same physical space, allowing one connector to physically block the other. This multi-functional design enables the electronic device to support multiple USB standards without requiring separate dedicated circuits for each standard, thereby reducing device complexity while maintaining compatibility.
2Reliability
If separate circuits are provided for each USB standard, then reliability of each standard is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges the circuit paths for USB Type-C and USB Type-A into a single shared circuit system. The wire branches to connect both port types to the same internal circuitry, eliminating the need for separate circuit boards, processors, and control logic for each USB standard. This consolidation reduces manufacturing costs by decreasing the quantity of electronic components and assembly steps, while the physical exclusive structure ensures that only one connector type is active at a time, maintaining reliable connections.
3Device complexity
If a branching wire structure is used to connect multiple USB ports, then circuit complexity is reduced, but signal leakage may increase
Solution Approach 1:
The patent applies preliminary anti-action by designing an exclusive physical structure where the USB Type-C connector and USB Type-A connector overlap in position. When one connector is inserted, it physically blocks the other connector from being inserted, preventing both connectors from being connected simultaneously. This preliminary prevention eliminates signal leakage issues that would arise from parallel wire connections, as only one active connection path exists at any given time. The branching wire structure is thus protected from the harmful effect of simultaneous multi-path signal transmission.

AI summary
An electronic apparatus is configured to include a first connection port that is a connection port of a USB Type C; a second connection port that is a connection port of a USB other than the USB Type C; and a wire that branches off to the first connection port and the second connection port. The electronic apparatus has an exclusive structure in which, in a case where a connector is connected to one of the first connection port and the second connection port, another connector is not able to be connected to the other connection port.
