Rear Carrier Height-Adjustable Wheel System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rear carriers for vehicle transport are laborious and uncomfortable to use, requiring manual loading and unloading, and often necessitate multiple transport means, which are costly and space-intensive.
Innovation Solution
A rear carrier with a height-adjustable wheel system that can be attached to a vehicle's trailer hitch, allowing for easy attachment and detachment, and featuring a design that enables both vehicle-bound and personal transport modes with minimal effort, using wheels or runners depending on the surface, to simplify loading, unloading, and transporting loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rear carrier is firmly connected to the vehicle for transport, then transport stability is improved, but loading and unloading becomes laborious and uncomfortable
Solution Approach 1:
The rear carrier incorporates a height-adjustable wheel system that can be positioned in different states: in the vehicle-bound transport state, the wheel is raised to provide stable transport with the vehicle, while in the personal transport state, the wheel is lowered to enable easy rolling movement for loading and unloading operations
Solution Approach 2:
The rear carrier is designed to be self-sufficient by integrating both vehicle-mounted transport capability and personal transport capability into a single device, eliminating the need for separate transport means and reducing the need for multiple people to assist with loading and unloading
2Adaptability or versatility
If multiple transport means are provided for loading and unloading, then transport flexibility is improved, but cost and parking space requirements increase
Solution Approach 1:
The rear carrier is designed as a multi-functional device that can operate in two distinct modes: vehicle-bound transport state for stable transport with the vehicle, and personal transport state for independent rolling movement. This eliminates the need for separate transport means such as wheel carts or additional vehicles
3Ease of operation
If the rear carrier is lowered on one side to simplify loading, then ease of operation is improved, but shock-sensitive loads can be damaged and dimensionally unstable loads can deform
Solution Approach 1:
Instead of lowering the entire rear carrier structure which causes loads to slip and deform, the invention selectively lowers only the wheel assembly while keeping the support body and transport surface stable and horizontal, thereby enabling easy rolling movement without compromising load integrity
4Ease of operation
If wheels are added to enable personal transport, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The wheel assembly is designed to be height-adjustable and repositionable between a lowered position for personal transport and a raised position for vehicle-bound transport, allowing the same structural elements to serve multiple functions without requiring separate wheel sets or complex additional mechanisms

AI summary
The invention presents and describes a rear carrier (1), preferably for mounting at the rear end of vehicles for the transport of loads in a transport state of the rear end carrier (1) when connected to the vehicle, with a carrying body (2) for receiving the load and/or for deposition of the load on the transport surface, and with a fastening device (3) for removable arrangement of the rear carrier (1) on the vehicle, particularly a passenger vehicle. According to the invention, at least one wheel (14) is provided for rolling transport of the rear carrier (1) and/or at least one runner is provided for sliding transport of the rear carrier (1), in a state in which the rear carrier (1) is separated from the vehicle and used by a person.
