Solution Overview
Problem
Existing connecting devices often cause recognition errors and connection defects due to the formation of separate branch lines when directly connecting two data pins, leading to signal distortion during transmission and reception between electronic devices.
Innovation Solution
A connecting device with a first connector and a second connector, where a recognition line connects a power pin of the first pin row to a recognition pin of the second pin row through a physical element, allowing the electronic device to determine the correct data line for signal transmission and reception by measuring voltage values associated with the recognition pin.

Engineering Contradiction Analysis
1Reliability
If two data pins are directly connected to form a separate branch line, then connection between electronic devices is established, but recognition errors and connection defects occur due to signal distortion
Solution Approach 1:
A recognition pin connected through a physical element (resistor) acts as an intermediary between the power pin and the data transmission system. This intermediary enables the electronic device to measure voltage and identify the correct data line before signal transmission, preventing direct connection errors without causing signal distortion in the actual data path.
Solution Approach 2:
The system performs preliminary voltage measurement through the recognition pin before establishing actual data transmission. This preliminary action allows the electronic device to identify which data line is connected and configure the correct communication path in advance, preventing recognition errors and connection defects during actual data transfer.
2Measurement precision
If a recognition pin is connected through a physical element to enable device identification, then data line determination accuracy is improved, but device complexity increases
Solution Approach 1:
The recognition pin structure serves multiple functions: it enables voltage measurement for data line identification, provides connection status detection, and facilitates device type recognition. By integrating these functions into a single pin configuration with a physical element, the system achieves high measurement precision without proportionally increasing complexity.
Solution Approach 2:
The system uses voltage parameter changes measured through the recognition pin to identify different connection states and data line configurations. By monitoring voltage levels that change based on connection status, the system achieves accurate data line determination through simple voltage measurement rather than complex identification mechanisms.
