Solution Overview

Problem

Conventional locomotive control systems face complexity issues due to disparate components that need to communicate effectively, lack of robust, mission-critical, extensible, and scalable components, leading to higher costs, non-standardized architecture, and complexity.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a centralized control system is used, then the system architecture is simple and consolidated, but the system lacks scalability, extensibility, and robustness for complex operations

Engineering Contradiction:
Improvecontrol system architectureVSAvoidsystem scalability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The control system is divided into multiple distributed electronic modules (safety-critical modules and non-safety-critical modules) that are spatially distributed throughout the locomotive. Each module handles specific control functions independently, allowing the system to scale and adapt while maintaining manageable complexity through modular architecture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a single centralized control point to a multi-dimensional distributed network of modules. This spatial and functional distribution across multiple locations and hierarchical levels enables both simplified individual module design and enhanced overall system scalability and versatility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If disparate components are integrated in a centralized system, then communication interfaces are consolidated, but the system becomes complicated and costly to maintain

Engineering Contradiction:
Improvecontrol system integrationVSAvoidsystem maintenance cost
Core Design Contradiction:
Device complexityVSEase of manufacture

Solution Approach 1:

Standardized communication interfaces and protocols are implemented across all electronic modules, allowing them to perform multiple functions and communicate universally. This standardization reduces maintenance complexity and costs by enabling interchangeable modules and simplified troubleshooting procedures.

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

Solution Approach 2:

The system employs configurable controllers that can dynamically adjust their operational parameters and communication protocols based on the specific module type and operational requirements. This flexibility allows standardized hardware to serve multiple purposes, reducing the variety of components that need to be maintained.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If safety-critical operations are handled by all modules, then operational safety is maximized, but system cost and complexity increase

Engineering Contradiction:
Improveoperational safetyVSAvoidmodule configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Different modules are configured with different levels of safety-critical capabilities based on their specific functions. Safety-critical modules implement rigorous safety protocols, while non-safety-critical modules use simplified configurations. This localized approach ensures safety where needed without unnecessarily complicating the entire system.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system dynamically determines which modules are safety-critical and which are not based on the specific operation being performed. This dynamic classification allows the system to maintain high safety standards for critical operations while using simpler, more cost-effective configurations for non-critical functions, reducing overall system complexity.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If a standardized scalable architecture is implemented, then system flexibility and extensibility improve, but initial system complexity increases

Engineering Contradiction:
Improvesystem flexibilityVSAvoidarchitecture design
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The standardized architecture is built by segmenting the control system into uniform, interchangeable electronic modules that follow common communication protocols and interface standards. This segmentation makes the initial architecture design more manageable while enabling future scalability and flexibility through simple module addition or modification.

Inventive Principle:
Principle #1Segmentation
