Solution Overview

Problem

Existing vehicle transportation systems require multiple tracks for return movement, leading to high area consumption and inefficient energy transfer, especially when handling long transport routes and large objects.

Innovation Solution

The system employs vehicles with coil windings for inductive energy transfer between adjacent vehicles, allowing for contact-free energy sharing and efficient movement along a single track, utilizing a high-capacity additional energy store for energy absorption and distribution during synchronized operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple tracks are used for return movement, then vehicles can operate efficiently, but area consumption increases significantly

Engineering Contradiction:
Improvevehicle operation efficiencyVSAvoidarea consumption
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The patent merges the outward and return movement tracks into a single shared track. Vehicles of different types (first and second vehicles) operate on the same track, with the smaller second vehicle being able to pass underneath or alongside the larger first vehicle, thereby eliminating the need for separate tracks and reducing area consumption while maintaining operational efficiency

Inventive Principle:
Principle #5Merging (Combining)

2Speed

If energy is transferred contactlessly between vehicles, then transmission speed increases, but energy loss increases

Engineering Contradiction:
Improveenergy transfer speedVSAvoidenergy loss
Core Design Contradiction:
SpeedVSLoss of energy

Solution Approach 1:

The patent introduces an intermediary energy storage device that temporarily stores energy received from the first vehicle and then transfers it to the second vehicle. This intermediary approach allows for controlled energy transfer, reducing losses compared to direct contactless transmission, while still maintaining high speed through the use of electromagnetic induction between the vehicles

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The invention relates to a method for transporting an object that can be received by or unloaded from vehicles, each of said vehicles having a drive capable of creating movement. The vehicles are arranged along a line, in particular an imaginary line, in particular a straight or curved travel route. In a first step, a first vehicle is driven up to a neighbouring vehicle along the line, in a second step, the object received by the first vehicle is transferred to the neighbouring vehicle along the line and in particular in a third step, the first vehicle is driven up to the respective other neighbouring vehicle along the line. The steps are in particular repeated.
