Solution Overview

Problem

Users often mistakenly connect display ports in input or output modes, leading to display malfunction due to the complexity of distinguishing between these modes, resulting in inefficient display functionality.

Innovation Solution

An electronic device with a processing module that automatically determines the data transmission mode of each interface based on connection status, adjusting the other interface to ensure correct data transmission direction without user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If display ports have fixed input/output modes, then data transmission direction is determined, but user operation complexity increases and connection efficiency decreases

Engineering Contradiction:

Improvedata transmission correctnessVSAvoidport connection simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The display device automatically detects connection status and self-adjusts port modes without user intervention. The processing module determines data transmission modes based on connection status, enabling the system to serve itself rather than requiring manual configuration by the user.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The port modes are made dynamic and adjustable rather than fixed. The display device can switch between different data transmission modes (first mode and second mode) based on real-time connection status, allowing the system to adapt to different operational scenarios automatically.

Inventive Principle:

Principle #15Dynamics

2Reliability

If manual mode identification is required, then data transmission accuracy can be ensured, but connection time and operational efficiency decrease

Engineering Contradiction:

Improvedisplay functionality correctnessVSAvoidconnection setup time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary detection of connection status automatically upon connection establishment. The processing module proactively determines the appropriate data transmission mode before actual data transmission begins, eliminating the need for manual mode selection and reducing connection setup time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements automatic feedback loops where the processing module continuously monitors connection status and adjusts port modes accordingly. This closed-loop control ensures correct display functionality while eliminating manual intervention, thereby reducing connection time and improving operational efficiency.

Inventive Principle:

Principle #23Feedback

AI summary

Electronic device includes: first interface configured to connect to first device; second interface configured to connect to second device; processing module, which is connected to the stated first interface and second interface and is capable of determining the data transmission mode of the first interface based on the connection status of the first interface and the first device. If the first interface is in a first data transmission mode, the stated processing module is also configured to adjust the second interface to be in a second data transmission mode. The difference between the stated first date transmission mode and the stated second data transmission mode is that the data transmission direction is different.
