Priority Port Linking Control Circuit for Direct Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional USB technologies, such as OTG, do not support data transmission between devices with special military specifications, requiring a third device as a master to facilitate communication, limiting direct end-to-end data exchange between devices with different port types.
Innovation Solution
An electronic device with a priority port and a linking control circuit that detects connections and automatically switches linking paths between an initial port and a system unit to a priority port when an external device is connected, enabling direct communication using OTG technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If OTG technology is used for data transmission between devices with special military specifications, then direct end-to-end data exchange is enabled, but the port must be an OTG-enabled USB port rather than a special specification port
Solution Approach 1:
The patent implements dynamic switching between two linking paths: a first linking path through an initial port and a second linking path through a priority port. The system automatically switches between these paths based on connection states, allowing the device to adapt to different external device types (OTG-enabled USB devices or special specification devices) without manual configuration. This dynamic path selection resolves the contradiction by enabling direct data transmission through the priority port while maintaining compatibility with existing OTG infrastructure.
Solution Approach 2:
The patent introduces a priority detection circuit as an intermediary component that detects the connection state of the priority port and controls the switching between linking paths. This intermediary mechanism automatically determines when to use the priority port for direct connection versus when to use the initial port for OTG connections, eliminating the need for users to manually configure port settings while maintaining both direct transmission and OTG functionality.
2Adaptability or versatility
If a third device serves as a master apparatus to facilitate data transmission between two slave devices, then data transmission can occur, but the transmission path becomes indirect and requires additional devices
Solution Approach 1:
The patent segments the data transmission path into two distinct options: a first linking path through an initial port that supports OTG technology with a third master device, and a second linking path through a priority port that enables direct master-slave communication without a third device. The priority detection circuit selectively activates the appropriate path based on the external device's capabilities, allowing the system to use direct transmission when possible and indirect transmission through a third device when necessary, thereby reducing overall system complexity.
3Productivity
If the priority port is used for direct connection, then direct end-to-end data transmission is achieved, but the linking path must be switched from the initial port
Solution Approach 1:
The patent implements self-service functionality through the priority detection circuit that automatically detects the connection state of the priority port and controls the switching between linking paths without user intervention. When an external device is connected to the priority port, the detection circuit automatically switches the linking path from the initial port to the priority port, enabling direct data transmission. This automatic self-service mechanism resolves the contradiction by achieving high-speed direct transmission while eliminating the need for manual path configuration.

AI summary
An electronic device includes a priority port, an initial port, a system unit a linking control circuit and a priority detection circuit. The linking control circuit usually establishes a first linking path between the initial port and the system unit. The priority detection circuit detects a connection state of the priority port. When detecting that the priority port is connected to a first external device, the priority detection circuit makes the linking control circuit to disconnect the first linking path and establish a second linking path between the priority port and the system unit.
