Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ethernet devices supporting transmission rates over 1 Gbps experience connection failures when connected via conventional wiring lacking additional twisted pairs, forcing them to use lower standards like 100Base-TX/10Base-T, resulting in performance limitations.
Innovation Solution
An Ethernet connection method and device that operate in a first mode using four twisted pairs and a second mode using one or two twisted pairs, with an error correction code mechanism between the media access control layer and physical layer to maintain high data transmission rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional wiring with only two twisted pairs is used, then ease of manufacture and installation is improved, but transmission rate and reliability deteriorate when connecting Ethernet devices supporting over 1 Gbps
Solution Approach 1:
The Ethernet device dynamically switches between first connection mode (using four twisted pairs for high-speed operation) and second connection mode (using one or two twisted pairs with ECC mechanism when pairs are insufficient). This dynamic adaptation allows the system to maintain reliable connections regardless of wiring configuration, resolving the contradiction between ease of manufacture and connection reliability.
Solution Approach 2:
The invention changes the operational parameters of the Ethernet device by introducing an ECC mechanism when operating in the second connection mode with limited twisted pairs. This parameter change (adding error correction) compensates for the reduced number of twisted pairs, maintaining connection reliability despite the simplified wiring configuration.
2Device complexity
If conventional wiring with only two twisted pairs is used, then device complexity is reduced, but transmission rate deteriorates for Ethernet devices supporting over 1 Gbps
Solution Approach 1:
The system dynamically adjusts its operational mode based on the available twisted pairs. When four twisted pairs are available, it operates in first connection mode achieving over 1 Gbps transmission rates. When only one or two twisted pairs are available, it switches to second connection mode with ECC mechanism, maintaining acceptable transmission rates while adapting to the simplified wiring configuration.
Solution Approach 2:
The invention segments the connection modes into two distinct operational states: first connection mode using four twisted pairs for high-speed operation, and second connection mode using one or two twisted pairs with ECC for lower-speed operation. This segmentation allows the system to optimize transmission rate based on the available wiring resources.
3Productivity
If four twisted pairs are used for high-speed operation, then data transmission rate is improved, but ease of operation deteriorates when conventional wiring with only two twisted pairs is available
Solution Approach 1:
The Ethernet device performs self-detection of the available twisted pairs and automatically selects the appropriate connection mode without requiring manual configuration or user intervention. The device self-adjusts between first connection mode (four pairs, high speed) and second connection mode (one or two pairs with ECC), making the system easy to operate regardless of the wiring configuration.
Solution Approach 2:
The system dynamically adapts its operational characteristics based on the detected wiring configuration. When four twisted pairs are detected, it operates in first connection mode for high-speed data transmission. When only one or two twisted pairs are detected, it automatically switches to second connection mode with ECC mechanism, maintaining ease of operation across different wiring scenarios.
