Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial automation systems face inefficiencies and increased costs due to the cumbersome and costly process of connecting multiple input/output (I/O) devices directly to communication networks, requiring numerous cables and network switches.
Innovation Solution
The implementation of a system using single pair Ethernet (SPE) conductors and communication option cards to efficiently connect and control multiple I/O devices, reducing the number of wires and option cards needed, and enabling communication between devices via different paths within the Ethernet network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each I/O device and drive is connected directly to the communication network, then communication reliability is improved, but device complexity and cost increase due to requiring multiple cables and network switches
Solution Approach 1:
The patent combines multiple communication paths into a single integrated system using SPE conductors. The communication option card merges data communication and power delivery into one cable connection, eliminating the need for separate cables for each device while maintaining reliable communication across the network.
Solution Approach 2:
The SPE conductor serves multiple functions simultaneously: it provides data communication and power delivery through a single cable. The communication option card enables the system to handle both Ethernet data traffic and Power over Ethernet (POE) functions through the same physical medium, reducing wiring complexity while maintaining system reliability.
2Adaptability or versatility
If multiple network switches are used to connect each product, then connectivity is improved, but ease of operation deteriorates due to cumbersome installation and management
Solution Approach 1:
The patent extracts the network switching function from external devices and integrates it into the communication option card within the drive. This eliminates the need for separate network switches for each product, simplifying installation and management while maintaining full connectivity capabilities across the automation system.
Solution Approach 2:
The communication option card acts as an intermediary device that bridges the SPE conductor connection and the internal communication network. It mediates between the single cable connection and multiple I/O devices, providing routing and switching functions without requiring external network switches.
3Productivity
If direct connection of each I/O device to the network is implemented, then communication efficiency is improved, but loss of substance increases due to requiring a bundle of cables
Solution Approach 1:
The patent merges multiple cable functions into a single SPE conductor connection. By combining data communication and power delivery into one cable, the system reduces cable material consumption while maintaining efficient communication between the drive and all connected I/O devices through the integrated communication option card.
