Solution Overview

Problem

Current bulk material transport systems, such as trucks, conventional trains, conveyor belts, and pipelines, face inefficiencies in energy use, labor costs, and environmental impact, particularly in terms of energy efficiency, capacity, and operational complexity, especially when handling bulk materials like minerals and aggregates.

Innovation Solution

The implementation of a high-speed communication network within the Rail-Veyor system for inter-drive station communication, allowing precise control of train speed and position, enabling multiple trains to operate efficiently on the same track without additional drive stations, using redundant sensors and Variable Frequency Drives (VFDs) to manage acceleration and deceleration, and ensuring continuous operation with minimal operator intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple trains operate on a single track system, then productivity increases, but control complexity and risk of collision increase

Engineering Contradiction:

Improvetransport capacityVSAvoidcontrol system complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The control system continuously monitors train positions using sensors at each drive station and adjusts drive station operations based on real-time position feedback. This feedback mechanism enables safe multiple train operation by automatically preventing collisions and managing train spacing without requiring complex manual coordination.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces mechanical collision prevention methods with an electronic communication network that transmits train position and speed data between drive stations. This electronic substitution allows multiple trains to operate safely on the same track by providing real-time digital monitoring and control rather than relying on physical separation mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If drive stations accelerate trains to target speed, then transport efficiency improves, but energy consumption increases

Engineering Contradiction:

Improvetransport efficiencyVSAvoidenergy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The control system uses periodic acceleration and deceleration cycles rather than continuous high-speed operation. Trains are accelerated to target speed only when necessary to maintain efficient transport, and decelerated when approaching drive stations or when other trains are present. This periodic action pattern reduces overall energy consumption while maintaining transport efficiency.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system monitors train speed and position continuously and adjusts acceleration commands based on feedback from sensors and communication between drive stations. This feedback control ensures trains accelerate only when needed and at optimal moments, avoiding unnecessary energy consumption while maintaining efficient transport schedules.

Inventive Principle:

Principle #23Feedback

3Reliability

If redundant sensors and communication networks are implemented, then system reliability improves, but device complexity increases

Engineering Contradiction:

Improvesystem reliabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system implements redundant sensors and communication pathways in advance to prevent failures before they occur. This proactive approach ensures that if one sensor or communication channel fails, backup systems are already in place to maintain reliable train monitoring and control, thereby improving system reliability without requiring complex failure detection and response mechanisms.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A train is driven by drive stations positioned along a track for frictionally contacting side plates on the train. The drive speed is controlled in response to sensors located at each drive station sensing a position of a wheel and a side plate for confirming a presence of the train. A start command is transmitted from the drive station driving the train to a second drive station downstream when a lead car is within a preselected distance from the second drive station. The drive station at the second drive station is quickly accelerated to a target speed for synchronizing the first drive station with the second drive station. After receiving the train, the second drive station then transmits a stop command to the first drive station for fast decelerating the drive station to a stop.
