Rotating Hitch Cargo Carrier Coupling for Heavy Load Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cargo carriers are heavy and require manual lifting to couple with vehicle trailer hitches, posing a challenge in ease of use.
Innovation Solution
A cargo hauling assembly with a mount-and-rotation tube assembly and a spring pin assembly that allows for easy coupling and decoupling of a cargo carrier to a trailer hitch, utilizing a circular end tubular portion and rectangular receiver tube for rotation and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cargo carriers are made heavy-duty to carry substantial loads, then load capacity is improved, but the weight of the carrier itself increases making it difficult to lift and couple manually
Solution Approach 1:
The patent introduces a vehicle-mounted tube assembly as an intermediary mechanism between the cargo carrier and the vehicle hitch. This tube assembly rotates with the carrier during coupling, enabling heavy carriers to be attached without manual lifting by utilizing the vehicle's own structure and movement to facilitate the coupling process.
2Device complexity
If cargo carriers are designed with traditional fixed coupling mechanisms, then structural simplicity is maintained, but the ease of attachment and detachment is reduced requiring significant manual effort
Solution Approach 1:
The patent implements a dynamic coupling mechanism where the tube assembly rotates along with the cargo carrier during attachment and detachment. This rotational movement transforms the static coupling process into a dynamic one, allowing heavy carriers to be easily coupled by simply lowering them onto the rotating tube assembly without requiring manual lifting or complex alignment procedures.

AI summary
A cargo hauling assembly having a mount-and-rotation tube assembly and a cargo carrier assembly is provided. The mount-and-rotation tube assembly has a main tubular portion, an end tubular portion, a circular end cap, and a spring pin assembly having first and second pins. The cargo carrier assembly has a rectangular-shaped frame, a receiver tube, and first and second wheels. The receiver tube is coupled to the rectangular-shaped frame. The receiver tube is sized and shaped to receive the end tubular portion in an interior region thereof. The cargo carrier assembly is coupled to the mount-and-rotation tube assembly such that first and second walls of the receiver tube are parallel to the first and second walls, respectively, of the main tubular portion and first and second pins are compressed by the first and second walls, respectively, of the receiver tube.
