Solution Overview

Problem

Conventional industrial automation devices require separate hardware and software configurations for different network topologies, leading to increased complexity and redundancy in product offerings, as a device configured for one network type cannot operate in another, such as transitioning from an Ethernet network to a NEO protocol network.

Innovation Solution

A multi-configurable device with firmware that supports operation in various network types, including Ethernet, DLR, EtherNet/IP, and NEO, allowing selection of network configurations through a configuration file or graphical user interface, enabling a single device to function across multiple network environments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate hardware configurations are used for different network topologies, then device reliability for specific network type is improved, but device complexity and inventory requirements increase

Engineering Contradiction:
Improvedevice reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a single device that can operate across multiple network topologies (Ethernet, DLR, Star, Linear) by providing configurable network interface cards and software protocols that adapt to different network types, eliminating the need for separate hardware configurations for each topology while maintaining reliability

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If separate hardware configurations are used for different network topologies, then network compatibility is improved, but manufacturing and inventory complexity increase

Engineering Contradiction:
Improvenetwork compatibilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The device incorporates multiple network interface card types (Ethernet, DLR, Star, Linear) that can be configured through software to operate on different network topologies, allowing a single manufacturing process to produce devices that are compatible with multiple network types rather than requiring separate production lines for each topology

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple network interface cards are integrated, then network versatility is improved, but device complexity increases

Engineering Contradiction:
Improvenetwork versatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device uses dynamic configuration where the selected network interface card type is determined at runtime based on the target network topology, allowing the device to adapt its behavior and active components dynamically rather than requiring all interface cards to be permanently active, thus managing complexity through dynamic activation

Inventive Principle:
Principle #15Dynamics
