Communication Interface Using Time-Interval Signal Encoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic products require separate lines for charging and communication, leading to resource wastage and limited user convenience due to the absence of an interface that supports bidirectional communication without directional limitations.
Innovation Solution
A communication system with a master and slave device configuration, utilizing a signal generation module to send data via time intervals corresponding to bit strings, and a signal receiving module to decode continuous time intervals, enabling two-line communication with adaptive reverse connection functionality.

1Reliability
If separate lines are used for charging and communication, then charging and communication functions are independent and reliable, but hardware resources are wasted and interface complexity increases
Solution Approach 1:
The patent combines charging and communication functions into a single interface by using time-division multiplexing. The same physical line alternates between carrying charging current and communication signals based on time intervals, eliminating the need for separate dedicated lines for each function and thereby reducing hardware resource consumption while maintaining functional independence
Solution Approach 2:
The interface is designed to perform multiple functions simultaneously - it can serve as both a charging interface and a communication interface. The universal interface uses protocol differentiation to enable the same physical connection to handle different types of signals (charging current vs. data) based on temporal patterns, making the hardware more efficient and versatile
2Ease of operation
If traditional interfaces are used, then communication protocol compatibility is maintained, but bidirectional communication capability is limited and user convenience is reduced
Solution Approach 1:
The communication interface dynamically adapts its behavior based on the connection orientation. The system detects whether the device is connected in the standard orientation or reverse orientation and automatically adjusts the communication protocol accordingly. This dynamic adaptation enables bidirectional communication capability while maintaining ease of operation, as users don't need to manually configure settings based on connection direction
Solution Approach 2:
The system changes communication parameters (such as signal polarity, timing sequences, and protocol selection) based on the detected connection orientation. By modifying these parameters dynamically, the interface can maintain compatibility with existing protocols while supporting bidirectional communication, thereby improving both ease of operation and adaptability
