Connector Switching for Video Signal Priority Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information processing devices lack the ability for users to freely set the priority of interface connectors that output video signals, limiting flexibility in connecting and managing external displays.
Innovation Solution
An information processing device with multiple output ports, connectors, detectors, and switches, controlled by a processor and controller that allows users to set priority based on connection states and stored setting information, enabling flexible video signal output management across various external displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple connectors are provided for connecting external displays, then connectivity and versatility are improved, but device complexity increases
Solution Approach 1:
The patent implements multiple connectors (HDMI, DisplayPort, USB Type-C) that can all output video signals, allowing the system to adapt to different display types and connection preferences. Each connector type serves multiple potential functions but is configured to provide video output capability, enhancing versatility without requiring separate dedicated outputs for each interface type.
Solution Approach 2:
The system dynamically switches video signal routing based on connector priority settings and detection of connected displays. The controller automatically determines which connector receives the video output by evaluating priority levels assigned to each connector type, enabling flexible adaptation to different connection scenarios without manual reconfiguration or hardwired assignments.
2Ease of operation
If automatic connector selection is implemented, then ease of operation is improved, but adaptability decreases
Solution Approach 1:
The system performs preliminary configuration by allowing users to assign priority levels to each connector in advance. These priority settings are stored and automatically applied when external displays are connected, eliminating the need for real-time manual selection while maintaining user preferences across different connection scenarios.
Solution Approach 2:
The controller continuously monitors which connectors have external displays connected and uses this feedback information alongside the stored priority settings to automatically determine video signal routing. The system adapts its behavior based on real-time connection status while respecting pre-configured user preferences, balancing automation with adaptability.
