Solution Overview

Problem

Conventional industrial Ethernet network systems require extensive reconfiguration and effort when failures occur, especially in long-distance extension units, due to the need for manual resetting of multiple units in a ring-shaped network configuration.

Innovation Solution

A network system and method that automatically determine and operate a network path using intrinsic numbers assigned to each Ethernet module, allowing the system to differentiate between single and dual ring network paths, and decide on master or slave modes based on connection status, thereby reducing the need for manual reconfiguration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual reconfiguration is performed for each extension unit when failure occurs in the Ethernet network, then network connectivity can be restored, but significant time and effort are consumed especially when extension units are located far apart

Engineering Contradiction:
Improvenetwork availabilityVSAvoidtime for re-setting extension units
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The extension units automatically detect connection states and determine network paths using intrinsic numbers without requiring manual intervention. The system self-configures by exchanging connection state information between dualized Ethernet modules and autonomously determines whether to operate in single-ring or dual-ring mode, eliminating the need for manual re-setting of extension units during failure recovery

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements automatic feedback mechanisms where extension units continuously monitor connection states of Ethernet cables and exchange information with neighboring units. Based on this feedback, the system dynamically determines network path topology and automatically adjusts operation mode, enabling rapid response to failures without manual intervention

Inventive Principle:
Principle #23Feedback

2Reliability

If dualized extension Ethernet modules are used to form ring networks, then network availability is improved through redundancy, but the complexity of determining network path and operation mode increases

Engineering Contradiction:
Improvenetwork availabilityVSAvoidcomplexity of network path determination
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Each extension unit is pre-assigned a unique intrinsic number before deployment. When the network operates, units automatically perform preliminary detection of connection states using these predefined intrinsic numbers, which simplifies the subsequent determination of network path topology and operation mode without requiring complex real-time analysis

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses intrinsic numbers as key parameters to identify and differentiate between dualized Ethernet modules. By changing the parameter set used for identification from generic addresses to unique intrinsic numbers, the network path determination process becomes simpler and more reliable, as each module can be uniquely identified and tracked

Inventive Principle:
Principle #35Parameter changes
