Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo carrying devices are limited to a single purpose and are not easily adaptable for multiple uses, and they lack versatility in mounting to a vehicle.
Innovation Solution
A portable cargo carrying device with a hinged frame, adjustable support members, removable wheels, and a saddle attachment system that allows it to pivot from a horizontal to an angled position, facilitating easy mounting and reduced effort in transporting loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cargo carrying device is mounted to a draw bar and hitch receiver, then it can support a load, but it is limited to a single purpose and lacks versatility
Solution Approach 1:
The cargo carrying device is designed with a frame that can function both as a traditional cargo carrier when mounted to a vehicle hitch, and as a portable hand truck when detached. The removable axle assembly with wheels and the adjustable support members enable the same structure to perform multiple functions - transporting cargo on a vehicle and manually transporting cargo on the ground, thereby achieving multi-functionality without requiring separate devices
Solution Approach 2:
The device is divided into separable components: a frame section, a removable axle assembly with wheels, and adjustable support members. This segmentation allows the user to detach the axle and wheels from the frame, transforming the device from a vehicle-mounted cargo carrier into a portable hand truck, thus enabling versatility while maintaining structural simplicity when each component is considered independently
2Adaptability or versatility
If a cargo carrier is designed for traditional hitch mounting, then it is stable for vehicle mounting, but it is not easily adaptable for portable use
Solution Approach 1:
The support members are designed to be adjustable in position and angle, allowing the device to adapt to different mounting conditions. When mounted to a vehicle hitch, the support members can be positioned to provide stable vehicle-mounted operation. When converted to portable use, the same adjustable support members can be reconfigured to provide stability for manual handling, thus achieving mounting flexibility without compromising reliability in either mode
3Ease of operation
If the cargo device is made portable and removable, then it becomes easier to maneuver and store, but it may reduce the stability and support capability
Solution Approach 1:
The axle assembly with wheels is designed as a removable component that can be detached from the frame. This segmentation enables easy maneuverability and storage when the device is not in use, as the wheels can be removed and stored separately. When needed, the axle assembly is reattached to restore full load support capability, thus achieving ease of operation without permanently compromising strength
Solution Approach 2:
The adjustable support members can be repositioned to provide optimal support when the device is being manually operated as a hand truck, and can be secured in fixed positions when mounted to a vehicle. This dynamic adjustability ensures that the removable and portable design does not sacrifice load support capability, as the support structure can be configured appropriately for each mode of operation
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
The device provides a versatile and efficient means of transporting loads across the ground, reducing the effort required to lift and move cargo by adjusting its position and securely attaching to a vehicle hitch, enabling multiple uses.
Implementation Method 1
a first section (14) and a second section (16) connected to one another by a hinge (18)
Implementation Method 2
The adjustable support member (42), at one end (44), is connected to the side support member (30), by a pivot pin (46) that permits the adjustable support member (42) to pivot from a first, or generally horizontal position, to a second raised or angled position

AI summary
A cargo carrying device is provided that is portable device and capable of transporting a load across the ground. The cargo carrying device has frame and a first section connected to a second section by a hinge. A plurality of side support members are connected to the frame as well as an adjustable support member that permits the cargo carrying device to pivot from a first, or generally horizontal position, to a second raised or angled position. The cargo carrying device also has an adjustable handle, a removable axel and removable pair of wheels. The cargo carrying device is mounted to a saddle for attachment to a hitch of a vehicle. This arrangement provides the user with an adjustable and portable cargo carrying device.
