Portable Motorcycle Towing Frame With Adjustable Loading Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle towing trailers are bulky, making storage inconvenient, and often require steep ramps for loading, which can be difficult for a single user to manage.
Innovation Solution
A portable towing system with wheel assemblies that can be assembled and disassembled by a single person, featuring a chassis that can be lowered for easy loading and raised for transport, using a raising and lowering mechanism integrated within the wheel assemblies to adjust height settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional towing trailers are designed to be stable and strong, then they can safely transport vehicles, but they become bulky and difficult to store
Solution Approach 1:
The towing trailer is divided into multiple separable components including frame sections, wheel assemblies, and loading mechanisms that can be disassembled and stored in compact configurations. The frame can be broken into modular segments that fit together when needed, reducing storage space requirements while maintaining structural integrity during use.
Solution Approach 2:
The trailer incorporates collapsible and adjustable structural elements that can transition between an expanded operational configuration providing full strength and stability, and a collapsed storage configuration reducing volume. The frame members can be folded or telescoped to achieve compact storage while maintaining structural strength when assembled for towing.
2Volume of moving object
If steep ramps are used for loading vehicles onto the trailer, then the trailer can be compact, but it becomes difficult for a single user to manage
Solution Approach 1:
The loading ramp is designed as a dynamically adjustable component that can change its angle and position. The ramp can be lowered to a shallower angle for easier single-user operation, or adjusted to steeper angles when needed. The ramp mechanism integrates with the trailer's height adjustment system, allowing the entire trailer chassis to be lowered closer to ground level, effectively reducing the loading angle without requiring a compact folded state.
Solution Approach 2:
The trailer's height adjustment mechanism is activated before loading to lower the chassis and ramp to a more accessible position. This preliminary action reduces the effort required by a single user to load a vehicle, as the loading surface is already at a convenient height without requiring the user to manually manage steep ramps during the loading process.
3Stability of the object's composition
If the trailer chassis is fixed at a high position for transport, then towing stability is improved, but loading becomes difficult for a single user
Solution Approach 1:
The trailer chassis incorporates a height adjustment mechanism that allows dynamic repositioning between a low loading position and a high transport position. During loading operations, the chassis is lowered to reduce the height difference between ground and trailer bed, making it easier for a single user to maneuver vehicles onto the trailer. Once loading is complete, the chassis is raised to its transport position to optimize towing stability and prevent excessive body roll during movement.

AI summary
A portable towing system for motorcycles or similar vehicles, such as trikes, features a frame that can be lowered to ground level for easy loading by pushing or riding the vehicle onto the frame. The system can be assembled, raised, lowered, and disassembled by a single person. Raising and lowering are achieved through a mechanism connected to the wheel assemblies. The system includes a towable cargo container with a walled container, a top that opens and closes, and left and right side openings in the rear sidewall. Left and right wheel assemblies with elongated tubes are insertable into these openings, oriented orthogonally to the wheel axes. A receiver for a vehicle tow bar allows the cargo container to be towed when connected to a vehicle.
