HDBaseT Ethernet Signal Selection Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display apparatuses fail to properly manage signal connections between HDBaseT and Ethernet standards, leading to incorrect signal insertion and lack of user warnings for misconnections, which hinders proper operation and selection of network signals.
Innovation Solution
A communication apparatus with multiple communicators and a controller that confirms signal connections and sets operation modes for HDBaseT and Ethernet signals, allowing for automatic selection and reconnection of signals, and providing user warnings for incorrect connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the apparatus selects only one of HDBaseT and Ethernet input signals, then the device complexity is reduced, but the adaptability to different signal connection statuses deteriorates
Solution Approach 1:
The patent implements dynamic signal selection where the apparatus automatically monitors connection status of multiple communicators and switches between HDBaseT and Ethernet modes based on real-time detection. The controller dynamically adjusts operation modes without requiring manual intervention, allowing the system to adapt flexibly to changing connection conditions while maintaining support for multiple signal standards.
2Use of energy by moving object
If the apparatus powers off communication circuits for non-set input signals, then the energy consumption is reduced, but the response time for signal reconnection deteriorates
Solution Approach 1:
The patent applies preliminary action by maintaining communication circuits in a low-power standby state rather than completely powering them off. The circuits remain in a ready state where they can quickly reactivate when signal connection status changes, avoiding the time penalty of cold startup while still achieving significant power savings compared to keeping all circuits fully active.
3Ease of manufacture
If the apparatus uses the same shaped connector for both Ethernet and HDBaseT, then the ease of manufacture is improved, but the reliability of correct signal connection deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the controller continuously monitors connection status and signal validity for each communicator. When a cable is inserted, the system actively detects whether the signal conforms to the expected standard (Ethernet or HDBaseT) and provides feedback through display units to guide correct connection. This feedback loop compensates for the lack of physical connector differentiation.
4Device complexity
If the apparatus does not display connection status warnings, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The patent applies self-service by implementing automatic connection status monitoring and display functionality that operates autonomously without requiring user intervention. The system automatically detects connection status, identifies mismatched cables, and displays warning information to guide users. This self-monitoring capability provides comprehensive operational awareness while maintaining relatively simple implementation through integrated controller functions.
