Solution Overview

Problem

Existing ASi-type network systems require costly and time-consuming cable terminations at multiple devices for power switching, particularly for emergency stop (E-stop) functionality.

Innovation Solution

A network module comprising a controller module and a switching module that provides switched auxiliary (AUX) power for E-stop system functionality without the need for costly cable terminations, using insulation displacement connections to efficiently couple cables to internal components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cable terminations are performed at multiple devices for power switching, then reliable E-stop functionality is achieved, but installation time and cost increase significantly

Engineering Contradiction:

ImproveE-stop functionalityVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent introduces an intermediary device (power switching module) that centralizes the power switching function. Instead of performing cable terminations at multiple end devices, the intermediary module handles all power switching operations through a single interface, thereby maintaining E-stop reliability while dramatically reducing installation time and complexity

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If cable terminations are performed at multiple devices for power switching, then reliable E-stop functionality is achieved, but installation cost increases significantly

Engineering Contradiction:

ImproveE-stop functionalityVSAvoidinstallation cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The intermediary power switching module consolidates the power switching functionality into a single device, eliminating the need for costly cable terminations at multiple locations. This approach maintains safety and reliability while reducing material costs and labor expenses associated with complex wiring installations

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If cable terminations are performed at multiple devices, then power switching capability is achieved, but system complexity increases

Engineering Contradiction:

Improvepower switching capabilityVSAvoidwiring complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The power switching module serves as a centralized intermediary that provides all necessary power switching capabilities through a single interface. This eliminates the need for complex multi-location cable terminations and wiring configurations, thereby maintaining full power switching functionality while dramatically simplifying the overall system architecture

Inventive Principle:
