Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rail-based transport systems are limited by the size and drive forces of individual carriers, restricting the size and mass of goods that can be transported, necessitating a solution for versatile and automatic coupling and decoupling of carriers.
Innovation Solution
The introduction of a carrier with a frame design featuring magnet couplings at its ends, allowing magnetic coupling and decoupling with adjacent carriers, and a control unit that manages these couplings to ensure synchronized movement and decoupling without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If carriers are used individually in rail-based transport systems, then the system structure remains simple and control is easy, but the size and mass of goods that can be transported is limited
Solution Approach 1:
The transport system is divided into modular carrier units that can independently operate or combine with others. Each carrier is a self-contained module with coupling mechanisms at its ends, allowing flexible assembly into different configurations based on transport needs.
Solution Approach 2:
Multiple carriers can be magnetically coupled end-to-end to form carrier trains, merging individual carrier capabilities to transport larger and heavier goods. The magnetic coupling mechanism enables reliable connection between carriers while maintaining the ability to separate when needed.
2Adaptability or versatility
If carriers are coupled to transport larger and heavier loads, then the capacity increases, but the risk of accidental decoupling increases
Solution Approach 1:
The control unit continuously monitors the magnetic coupling state of carriers and adjusts driving forces accordingly. When carriers are coupled, the system detects this state and modifies control parameters to prevent excessive forces that could cause decoupling, while still enabling separation when intentionally required.
Solution Approach 2:
The magnetic coupling strength is dynamically adjustable through control of the electromagnets in the coupling mechanism. The system can adapt the coupling force in real-time based on operational conditions, strengthening the connection when stability is critical and allowing controlled separation when needed.
3Extent of automation
If magnetic coupling mechanisms are added to carriers, then automatic coupling and decoupling is enabled, but the device complexity increases
Solution Approach 1:
The magnetic coupling mechanism is designed to automatically engage and disengage carriers based on their relative positions and magnetic attraction forces. The system requires minimal external intervention, with the magnetic fields themselves driving the coupling and decoupling processes without complex mechanical fastening systems.
Solution Approach 2:
Traditional mechanical coupling mechanisms (such as latches, clamps, or interlocking structures) are replaced with magnetic coupling systems. This substitution eliminates the need for complex mechanical actuation and locking mechanisms, using magnetic fields to achieve reliable connection and separation.
4Power
If multiple carriers are coupled together, then the drive force and platform size increase, but the control complexity increases
Solution Approach 1:
The control unit is designed to handle both single-carrier and multi-carrier operations through a unified control architecture. The same control system manages individual carriers, coupled carriers, and carrier trains, adapting its behavior based on the detected configuration without requiring separate control systems for different operational modes.

Function Achieved in This Case
Enables the transportation of larger and heavier loads by coupling carriers, maintaining control over coupled trains while preventing accidental decoupling, thus enhancing the system's capacity and efficiency.
Implementation Method 1
a first magnet coupling (22a) is attached to the first end (21a) of the carrier (20) for magnetically coupling the carrier (20) to another such carrier
Implementation Method 2
The rail (30) may comprise an arrangement of plural electromagnets (34)... Each of them may be individually drivable either on/off or also regarding their amplitude... They generate magnetic forces cooperating with the magnetic structure in carrier (20) for generating driving, accelerating or decelerating forces
Implementation Method 3
Magnetic forces may also be involved for holding the carrier at the rail
