Solution Overview

Problem

Current cargo delivery systems using ground transportation face challenges such as long delivery times, inaccurate delivery estimates, and limited capacity due to increased e-commerce volumes, particularly in urban areas with poor traffic conditions.

Innovation Solution

A railway cargo delivery system that includes a cargo load and unload unit installed at railway stations and a cargo stacking unit inside railway cars, allowing for simultaneous and speedy loading and unloading of large quantities of cargo without increasing dwell time, using modules like load transfer units, rolling plates, and stacking modules controlled by a stacking control unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If ground transportation is used for cargo delivery, then delivery can be performed using existing infrastructure, but delivery time increases and delivery capacity is limited due to traffic conditions

Engineering Contradiction:

Improvedelivery capacityVSAvoiddelivery time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent introduces railway stations and railway cars as intermediary infrastructure for cargo delivery. Instead of direct ground transportation from supplier to consumer, cargo is transported via railway network between stations, significantly improving delivery capacity and reducing delivery time while avoiding urban traffic congestion

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the conventional ground transportation mechanical system (vehicles on roads) with a railway-based mechanical system (trains on tracks). This substitution enables higher delivery capacity and faster delivery times by utilizing dedicated railway infrastructure separate from road traffic

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If cargo loading and unloading is performed manually, then system complexity is reduced, but loading and unloading speed decreases and dwell time increases

Engineering Contradiction:

Improveloading and unloading speedVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent implements automatic cargo loading and unloading systems where the cargo stacking unit and cargo load/unload unit automatically transfer cargo between railway car and platform without manual intervention. The system uses automated conveyors, stacking mechanisms, and control units to perform loading/unloading operations independently

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent employs automated mechanical systems with enhanced processing speed to accelerate the cargo loading and unloading process. The cargo stacking unit and load/unload unit use powered mechanisms that rapidly move and position cargo, significantly reducing dwell time compared to manual operations

Inventive Principle:

Principle #38Strong oxidants (Accelerated oxidation)

3Quantity of substance

If large quantity of cargo is stacked in railway car, then delivery capacity increases, but cargo loading and unloading becomes more complex and time-consuming

Engineering Contradiction:

Improvecargo quantityVSAvoidstacking complexity

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent divides the cargo stacking system into modular components: cargo stacking unit with multiple stacking positions, cargo load/unload unit with separate loading and unloading sections, and organized storage regions within the railway car. This segmentation allows efficient management of large cargo quantities through systematic organization and automated handling of individual cargo units

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent utilizes three-dimensional stacking space within the railway car, organizing cargo in vertical and horizontal dimensions. The cargo stacking unit stacks cargo in multiple layers and positions, maximizing space utilization while maintaining automated access for loading and unloading operations

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

4Productivity

If railway car stops at station for cargo operations, then cargo can be loaded and unloaded, but dwell time increases and delivery speed decreases

Engineering Contradiction:

Improvedelivery capacityVSAvoiddelivery speed

Core Design Contradiction:

ProductivityVSSpeed

Solution Approach 1:

The patent implements continuous automated cargo loading and unloading operations during the railway car's brief stop at the station. The cargo stacking unit and load/unload unit operate simultaneously and efficiently to complete all cargo transfer operations within the limited dwell time, minimizing the stop duration while maximizing delivery capacity

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A system to deliver a cargo using a railway, such as a subway or a national railway, rather than ground transportation. A cargo loading/unloading unit is provided on a platform of a railway station. The cargo loading/unloading unit is configured to load and unload cargoes is provided inside a railway vehicle, such that a large quantity of cargo can be quickly loaded and unloaded while the railway vehicle is stopped at the station. The cargo delivery capacity can also be adjusted, thereby enabling a large quantity of the cargo to be delivered more quickly and conveniently.
