USB Type-C Connection State Detection for Auto Reconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing USB Type-C systems require manual re-plugging to correct connection errors, which can disrupt normal charging and data transmission.
Innovation Solution
A detection method that automatically identifies connection errors by switching between connection states and power supply to USB Type-C, allowing automatic reconnection without physical re-plugging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual re-plugging is performed to correct connection errors, then connection reliability is improved, but operation convenience deteriorates and time loss increases
Solution Approach 1:
The system performs self-diagnosis and self-correction of connection errors automatically. The host system detects connection states, identifies errors, and executes correction commands without requiring user intervention, making the system serve itself to maintain reliable connections.
Solution Approach 2:
The system continuously monitors connection states and provides feedback to the host system. When connection errors are detected, the feedback triggers automatic correction mechanisms, creating a closed-loop control system that maintains connection reliability through continuous detection and correction.
2Reliability
If manual re-plugging is performed to correct connection errors, then connection reliability is improved, but time loss increases
Solution Approach 1:
The system performs preliminary detection of connection states continuously in the background. When errors are detected, correction actions are immediately executed without waiting for user awareness or intervention, thereby preventing time loss that would occur with manual re-plugging operations.
Solution Approach 2:
The automatic detection and correction mechanism enables the system to self-heal connection errors instantly, eliminating the time required for manual re-plugging operations and maintaining continuous operational reliability.
3Ease of operation
If automatic detection and correction is implemented, then operation convenience is improved, but device complexity increases
Solution Approach 1:
The host system performs multiple functions including connection detection, error identification, command generation, and state management using existing USB communication protocols. This multi-functionality approach avoids adding separate dedicated hardware components, thereby limiting the increase in device complexity.
Solution Approach 2:
The system replaces manual mechanical re-plugging operations with electronic software-based detection and correction mechanisms. This substitution eliminates the need for physical user actions while implementing automatic correction through software control of USB connection states.
4Reliability
If connection state switching is performed to correct errors, then connection reliability is improved, but power consumption increases
Solution Approach 1:
The system performs partial connection state switching only for the specific port experiencing errors, rather than resetting all USB connections. This targeted approach maintains connection reliability for the affected port while minimizing power consumption impacts on the entire USB system.

AI summary
A detection method of universal serial bus Type-C includes identifying a first connection state between a universal serial bus Type-C and a connection port through a host system, determining whether the first connection state accords with a default connection state through the host system. When a result of the determination is no, transferring a first command through the host system to cutoff the first connection state between the universal serial bus Type-C and the connection port, and transferring a second command through the host system to connect the universal serial bus Type-C and the connection port in the default connection state.
