Motorcycle Tyre Lifting Dolly with Nested Segmented Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dollies for maneuvering motorcycles and motor scooters are often large, heavy, complex, and difficult to store, with limited versatility and compatibility with modern vehicles, especially those without center stands or obstructions under the frame.
Innovation Solution
A tyre interfacing dolly with axially aligned wheels and a frame that lifts and supports the motorcycle or scooter tyre off the ground using ramped tyre supporting members, allowing for easy positioning and movement without requiring fastening to the frame, combined with omni-directional wheels for versatile horizontal movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional dollies are used to lift motorcycles off the ground, then the motorcycle can be maneuvered, but the dolly becomes large, heavy, and difficult to store
Solution Approach 1:
The dolly is divided into two separate frame parts (front frame part and rear frame part) that can be independently positioned and connected. This segmentation allows the dolly to be compact when not in use while still providing full lifting capability when deployed, resolving the contradiction between maneuverability and storage weight.
Solution Approach 2:
The front frame part nests within or alongside the rear frame part when not in use, creating a compact storage configuration. The nested structure reduces the effective size and weight perception of the dolly while maintaining its full functional capability when deployed.
2Ease of operation
If complex lifting mechanisms are used to raise motorcycles, then lifting capability is achieved, but the device complexity increases
Solution Approach 1:
The complex intermediate lifting mechanisms (levers, struts, multiple connection points) are extracted and replaced with a direct rigid connection between the two frame parts. The lifting action is achieved simply by lowering the rear frame part, which directly raises the front frame part and the motorcycle, eliminating unnecessary complexity.
Solution Approach 2:
Instead of using complex mechanisms to lift the motorcycle directly, the invention inverts the approach by lowering the rear frame part to indirectly raise the front frame part. This inversion simplifies the mechanism while achieving the same lifting effect.
3Ease of operation
If dollies are designed to work with specific motorcycle types, then lifting effectiveness is improved, but adaptability to different vehicle types decreases
Solution Approach 1:
The dolly is designed with universal features that allow it to work with various motorcycle and scooter types. The open end of the front frame part can accommodate different tyre sizes, and the rigid connection between frame parts provides consistent lifting action across different vehicle weights and configurations, achieving both effectiveness and versatility.
4Reliability
If dollies require modification to the motorcycle frame, then connection stability is improved, but the ease of use decreases due to installation requirements
Solution Approach 1:
The requirement for frame modifications is extracted and eliminated. The dolly achieves stable connection by interfacing with the motorcycle tyre through the open end of the front frame part, which naturally locates and secures the tyre without requiring any alterations to the motorcycle frame or components.

AI summary
A dolly for supporting a tyre of a motorcycle or motor scooter off the ground is provided. The dolly comprises: axially aligned wheels supported by a frame which has a frame part forward of the wheels and a frame part behind the wheels, the forward frame part having an open end being such that the motorcycle or motor scooter tyre can locate in the open end, at least one tyre gripping member on the forward frame part and adapted to wedge the tyre when the forward frame part is lifted and release the tyre when the forward frame part is lowered, and a wheel on the frame part behind the wheels.
