Tire Work Stand with Bridge-Inhibited Roller for Heavy Tire Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire work stands are inefficient for loading and unloading heavy tires, especially unmounted tires, due to opposing force vectors that prevent the tire from seating properly on the rollers, making it difficult to rotate and inspect heavy-duty truck tires.
Innovation Solution
A tire work stand with a frame, rollers, a ramp, and a bridge that inhibits roller rotation during loading and allows easy rotation during inspection, featuring a hinge on the ramp and bridge for adjustable clearance and stability, ensuring the tire can be easily loaded and unloaded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple ramp is used for loading tires, then the device is simple and easy to manufacture, but the tire cannot be properly loaded when the force vector opposes the roller rotation
Solution Approach 1:
A bridge structure is introduced as an intermediary element between the ramp and the roller. The bridge contacts the roller at a point that prevents the roller from rotating during the loading process, thereby mediating the force transmission and enabling the tire to be properly loaded onto the work stand.
Solution Approach 2:
The system transitions from a static simple ramp to a dynamic configuration where the bridge can be positioned to engage or disengage with the roller. During loading, the bridge engages to prevent roller rotation; during operation, the bridge can be repositioned to allow free roller rotation, providing dynamic adaptability to different operational states.

Function Achieved in This Case
Facilitates efficient loading and unloading of heavy tires by minimizing the vertical displacement required, allowing for easier rotation and inspection of tires, including heavy-duty truck tires, and maintaining stability through frictional contact with the ground.
Implementation Method 1
maintaining stability through frictional contact with the ground
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

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.
