Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing freight transportation systems, including railroads and utility delivery systems, are inefficient in terms of cost per ton-mile, especially for last-mile distribution, with utility systems like municipal water and natural gas utilities not adequately accounted for in current statistics, leading to high costs for delivery of goods and services.

Innovation Solution

A track system with a lower and upper track, supported by opposed sidewalls, and vehicles equipped with drive units and side wheel assemblies that allow independent engagement with the track, enabling efficient navigation through bifurcations and power supply via a voltage differential, with onboard switching mechanisms to manage direction changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional railroad freight transportation is used, then long-haul transport efficiency is improved, but last-mile distribution cost per ton-mile increases significantly

Engineering Contradiction:

Improvelong-haul transport efficiencyVSAvoidcost per ton-mile

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The system segments the transportation network into long-haul railroad segments and last-mile automated vehicle segments. The automated vehicles operate on dedicated guideways that connect to railroad terminals, allowing seamless transfer of containers without traditional trucking. This segmentation resolves the contradiction by optimizing each segment for its specific function while reducing overall cost per ton-mile for last-mile delivery.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The automated vehicles serve as an intermediary between the railroad system and final destinations. These vehicles take over from the railroad at terminals and complete the last-mile delivery, eliminating the need for expensive traditional trucking while maintaining the efficiency benefits of rail for long-haul transport.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Use of energy by moving object

If utility delivery systems are used for freight transport, then cost per ton-mile is reduced, but system adaptability and flexibility worsen

Engineering Contradiction:

Improvecost per ton-mileVSAvoidsystem flexibility

Core Design Contradiction:

Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The automated vehicle system implements dynamic routing and scheduling capabilities that allow real-time adaptation to different delivery requirements. Vehicles can be dynamically assigned to different destinations, routes, and time slots, providing the flexibility traditionally associated with trucking while operating on cost-effective utility-like infrastructure.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The automated vehicles are designed as multi-functional units that can transport various types of freight containers and adapt to different delivery scenarios. The system can serve multiple customers and destinations using the same infrastructure, achieving universality that combines the low cost of utility systems with the flexibility needed for diverse freight requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If automated vehicles with independent wheel assemblies are used, then path selection at bifurcations is improved, but device complexity increases

Engineering Contradiction:

Improvepath selection capabilityVSAvoidvehicle structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The vehicle's wheel assembly is segmented into independent modules, with each wheel assembly capable of independent operation. This segmentation allows each wheel assembly to independently engage with the guideway at bifurcations, simplifying the control mechanism while improving path selection capability. The modular design reduces overall system complexity by distributing functionality across independent components.

Inventive Principle:

Principle #1Segmentation
