Motorcycle Lifting Tool with Adjustable Screw Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle jacks have limited adjustability, preventing them from accommodating wheel sizes shorter than the fixed bore distance, which restricts their practical use in motorcycle maintenance.
Innovation Solution
A motorcycle lifting tool with a foldable and expandable main body, a screwedly rotatable holding seat, and an adjustment support device that allows the axial length between the support member and holding seat to be adjusted, enabling the tool to lift the rear wheel to a predetermined height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the motorcycle jack uses fixed bores for length adjustment, then the structure is simple, but the adjustability is limited and cannot accommodate lengths less than the fixed bore distance
Solution Approach 1:
The patent transforms the static fixed-bore structure into a dynamic adjustable structure. The support member can slide along the main body and be locked at different positions using the fixing member, enabling continuous length adjustment rather than fixed discrete positions. This resolves the contradiction by making the structure adaptable while maintaining reasonable complexity through a sliding-mechanism with selective locking points.
Solution Approach 2:
The patent divides the length adjustment function into two independent adjustment mechanisms: (1) the support member length adjustment relative to the main body, and (2) the holding seat axial length adjustment relative to the support member. This segmentation allows each mechanism to be optimized independently, achieving fine-grained adjustability without excessive overall complexity.
2Adaptability or versatility
If the motorcycle jack has fixed length configuration, then the device is simple to manufacture, but it cannot meet diverse user demands for different wheel sizes
Solution Approach 1:
The patent enables the motorcycle jack to adapt to different wheel sizes through dynamic length adjustment. The support member can be positioned at different locations along the main body, and the holding seat can be adjusted axially on the support member, allowing the device to accommodate various wheel diameters and configurations without requiring multiple fixed models.
Solution Approach 2:
The patent creates a universal motorcycle jack design that can serve multiple functions and accommodate different motorcycle types. The adjustable length mechanisms allow the same device to work with various wheel sizes, making it a multi-functional tool rather than a single-purpose device limited to specific wheel dimensions.

AI summary
A motorcycle lifting tool includes a main body, a support member, a hold seat, a fixing member, and an adjustment support device. The main body has a first end and a second end foldable against each other. The second end stands on the ground. The support member is linearly disposed at the first end and has a screw end and a support end, wherein the screw end is exposed at the outer side of the first end. The hold seat is screwed to the screw end for holding the rear wheel of the motorcycle. The fixing member removably fixes the support member to the main body. The adjustment support device is disposed between the main body and the support member for supporting the support end. When the fixing member is removed, the adjustment support device drives the support member to move outward from the main body.
