Portable Tire Changing Stand With Upright Stable Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire changing stands for motorcycles are ergonomically uncomfortable, unstable, and lack portability due to their low design and heavy construction.
Innovation Solution
A portable tire changing stand designed with a frame that sits at a 30-90 degrees angle, featuring a rear support leg, horizontal front leg, removable center shaft, ratchet mechanism, and adjustable lever system, which allows for stable operation in an upright position and easy transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional low design tire changing stand is used, then the structure is simple, but the ergonomics are poor and the user must work in a low, uncomfortable position
Solution Approach 1:
The patent transforms the traditional horizontal/low working position into a vertical/upright working position by raising the tire mounting head to a height suitable for ergonomic operation. The frame structure is designed with vertical orientation, allowing the user to work standing up rather than bending over, thus solving the ergonomics problem while maintaining structural simplicity.
2Ease of operation
If a portable tire changing stand with upright position is designed, then the ergonomics are improved, but the stability may be compromised
Solution Approach 1:
The patent incorporates a self-stabilization mechanism where the frame structure is designed with a wide base and vertical orientation that automatically provides stability when in the upright working position. The geometry of the frame and support legs is pre-configured to distribute weight and resist tipping, ensuring stability is built into the structure before operation begins.
3Stability of the object's composition
If a heavy construction is used for stability, then the stability is improved, but the portability is reduced
Solution Approach 1:
The patent achieves stability without heavy construction by optimizing the geometric parameters of the frame structure. The vertical orientation, base width, and leg positioning are carefully designed to provide maximum stability with minimum weight. The structure uses efficient weight distribution and structural geometry rather than mass to achieve stability, enabling portability while maintaining operational stability.
4Stability of the object's composition
If the frame is designed to be stationary, then the stability during operation is improved, but the portability is reduced
Solution Approach 1:
The patent designs the frame with removable and adjustable components that allow the structure to transition between a stable working configuration and a compact transport configuration. The vertical frame can be disassembled or folded into a compact form for easy transport, yet when assembled and in use, it provides a stable platform for tire changing operations. This dynamic design enables both portability and stability at different operational states.

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 solution provides ergonomic comfort and stability during tire changes, allowing users to operate in an upright position without the need for additional stabilization, while also being lightweight and easy to disassemble for enhanced portability.
Implementation Method 1
a ratchet mechanism with a tire mounting head, placed on the center shaft
Implementation Method 2
A lever is attached to the socket that is attached to the bracket, and the tire bead is pushed off the rim with the plate on the side

AI summary
A portable tire changing stand that includes a frame, a rear support leg and a horizontal front leg that attaches to the lower end of the frame and is removable. A removable center shaft perpendicular to the frame is attached to the central part of the frame. For accurate centering of the rim, a stepped bushing is arranged on the center shaft. Plastic support surfaces are attached to the frame above and below the center shaft. A tire lever is attached to the socket and a tire bead is pushed off the rim with the plate attached to the lever. The position of the plate can be adjusted by changing the distance between the bracket and the center shaft. A socket is attached to the ratchet mechanism and the lever attached to it gives the mounting head movement around the center shaft.
