Vehicle Carrier Rail with Electromagnetic Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for loading cargo on vehicles, such as fixing cargo to the roof or tailgate, are inconvenient due to the need for separate carrier apparatuses and manual installation/removal, which obstructs indoor space and user convenience, especially for bulky items.
Innovation Solution
A carrier apparatus with stationary and transfer rails that allow cargo to be fixed and adjusted electrically on the outside of vehicles, using electromagnets and movable sockets to securely attach cargo to the vehicle, improving user convenience and space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cargo is fixed to the roof panel of the vehicle, then cargo loading capacity is improved, but loading convenience deteriorates due to very inconvenient loading process
Solution Approach 1:
The carrier apparatus is divided into multiple detachable brackets that can be independently positioned and attached to the stationary rail at different locations, allowing flexible cargo placement without requiring a complex fixed roof-mounted system
Solution Approach 2:
The carrier apparatus transitions from a static fixed installation to a dynamic reconfigurable system where brackets can be moved along the stationary rail and attached at different positions to accommodate various cargo sizes and loading preferences
2Quantity of substance
If a separate carrier apparatus is installed on the rear of the tailgate, then cargo loading capacity is improved, but device complexity increases due to required separate installation
Solution Approach 1:
The carrier apparatus is integrated with the vehicle's existing stationary rail structure, combining the cargo carrying function with the vehicle's existing framework rather than requiring a completely separate tailgate-mounted system
Solution Approach 2:
The stationary rail serves multiple functions: it provides structural support for the vehicle, guides the movement of brackets, and enables cargo carrying capabilities, eliminating the need for separate dedicated cargo apparatus
3Quantity of substance
If manual installation and removal of carrier apparatus is required, then cargo loading capacity is improved, but time consumption increases due to troublesome installation and removal processes
Solution Approach 1:
The manual mechanical attachment process is replaced with an electromagnetic attachment system where brackets are automatically attracted to and held by electromagnetic actuators on the stationary rail, eliminating the need for manual installation and removal
Solution Approach 2:
The carrier apparatus performs self-installation and self-removal through automated electromagnetic attachment and detachment mechanisms, eliminating the need for manual intervention in the installation and removal processes
4Volume of moving object
If cargo is loaded on the outside of the vehicle, then indoor space is secured, but field of vision may be obstructed
Solution Approach 1:
The carrier apparatus enables dynamic repositioning of cargo along the stationary rail, allowing cargo to be placed at optimal positions that maximize indoor space utilization while minimizing obstruction of the driver's field of vision
Solution Approach 2:
The system allows different portions of the stationary rail to serve different functions: upper portions for cargo carrying and lower portions maintaining clear visibility, creating local optimization of space utilization versus field of vision
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy loading and unloading of various cargo sizes by automatically adjusting the position of cargo on the vehicle, enhancing user convenience and maintaining indoor space, while securely fixing cargo without obstructing the vehicle's field of vision.
Implementation Method 1
The stationary rail or the position-fixing bracket may be made of an electromagnet such that an attractive force is generated therebetween when a signal is input
Implementation Method 2
When the transfer rail and the moving socket come into contact with each other, the moving socket may be mounted to the transfer rail by the attractive force therebetween

AI summary
A carrier apparatus for a vehicle includes a stationary rail extending from a rear part of the vehicle to an upper part of the vehicle in a forward-rearward direction of the vehicle; and a position-fixing bracket separably mounted to the stationary rail for fixing cargo placed on the stationary rail, such that the cargo fixed to the stationary rail is located at the rear part or the upper part of the vehicle when the position-fixing bracket is mounted to the stationary rail.
