Tire Work Stand Bridge Structure for Easier Heavy Tire Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire work stands are inadequate for easily loading and unloading heavy tires, especially those not attached to a vehicle, due to opposing force vectors that hinder the tire's rotation and seating on the rollers.
Innovation Solution
A tire work stand with a frame, rotatable rollers, a ramp, and a bridge that inhibits roller rotation during loading and allows free rotation after loading, ensuring easy mounting and unloading of tires by managing force vectors and minimizing vertical displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple ramp is used for loading tires, then the structure is simple and easy to manufacture, but the tire cannot be easily loaded when the force vector opposes the rolling direction
Solution Approach 1:
The bridge acts as an intermediary component between the ramp and the roller. It provides a transition surface that allows the tire to overcome the roller without causing the roller to rotate. The bridge temporarily supports the tire during the loading process, mediating the force transfer between the ramp and the roller.
Solution Approach 2:
The bridge is positioned to preemptively counteract the harmful effect of roller rotation during tire loading. By placing the bridge in the path of the tire before the tire contacts the roller, it prevents the roller from rotating in the wrong direction before the tire can properly engage with the roller surface.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates efficient loading and unloading of heavy tires by managing force vectors and reducing the angle of rotation, making it suitable for both mounted and unmounted tires, including heavy-duty truck tires.
Implementation Method 1
the bridge acts to inhibit rotation of the roller during loading of the tire
Implementation Method 2
A plurality of rollers is attached to the frame to support a tire above the ground surface and to permit rotation of the tire during inspection of the tire
Implementation Method 3
The frame is in frictional contact with the ground surface to aid in the stability of the tire work stand

AI summary
A tire work stand comprises a frame for supporting the work stand on a ground surface and for attaching a set of components to the tire work stand. A plurality of rollers is attached to the frame to support a tire above the ground surface and to permit rotation of a tire during inspection of the tire. A ramp is configured to have a first ramp end capable of extending from the ground surface and a second ramp end extending to a position proximal to the frame. A bridge is configured to have a first bridge end extending from the second ramp end and a second bridge end extending to a position proximal to a surface of at least one of the rollers, wherein the bridge acts to inhibit rotation of the roller during loading of the tire and further permits rotation of the tire after the tire has been loaded on the tire work stand.
