Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Changing or rotating tires on a vehicle is cumbersome due to the need to lift and align heavy wheel assemblies, which requires a device that can simplify this process.
Innovation Solution
A lifting device comprising an elongated rigid plate with a pedal portion and a wheel portion, equipped with a ground roller and wheel rollers, allowing for easy lifting, rotation, and positioning of wheels for mounting or dismounting from a vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a person manually lifts and positions a heavy wheel assembly, then the wheel can be mounted on the vehicle, but the operation becomes cumbersome and labor-intensive
Solution Approach 1:
The patent introduces a lifting device as an intermediary tool between the operator and the heavy wheel assembly. This device includes a rigid plate with a pedal portion for applying force and a wheel portion with rollers that contact the wheel assembly, enabling easy lifting and positioning without direct manual handling of the heavy wheel
Solution Approach 2:
The lifting device incorporates rollers (ground roller and wheel rollers) that transform static friction into dynamic rolling motion. This allows the device to easily move and position the wheel assembly by converting the lifting action into a rolling mechanism that reduces friction and effort
2Strength
If the wheel assembly is heavy, then it provides durability and load-bearing capacity, but it becomes difficult to align and position during mounting
Solution Approach 1:
The lifting device serves as a mediator that interfaces with the heavy wheel assembly through its tread. The rigid plate structure provides sufficient strength to support the wheel's weight while the pedal mechanism and rollers enable precise alignment and positioning without requiring the operator to directly handle the heavy wheel
Solution Approach 2:
The lifting device introduces a new dimension of operation by using a pedal portion that applies force vertically while the wheel portion moves horizontally. This separation of force application direction and movement direction enables easy alignment and positioning of the heavy wheel assembly
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
The device facilitates efficient lifting, rotation, and positioning of wheels, making the tire-changing process simpler and less labor-intensive, while ensuring stability through engagement at the tire tread.
Implementation Method 1
A ground roller is fixed with the bottom side of the elongated rigid plate proximate the wheel portion
Implementation Method 2
At least two wheel rollers are fixed with the wheel portion of the elongated rigid plate
Implementation Method 3
the pedal portion may be pressed downwardly such as with a person's foot to pivot the elongated rigid plate about the ground roller to lift the wheel

AI summary
A device for lifting a wheel and rolling the wheel on a surface includes an elongated rigid plate having a top side, a bottom side, a peripheral edge, a pedal portion at a rear end of the rigid plate, and a wheel portion at a forward end of the rigid plate. A ground roller is fixed with the bottom side of the rigid plate and at least two wheel rollers are fixed with a top side of the wheel portion. In use, with the wheel resting on the wheel rollers, the pedal portion may be pressed downwardly to pivot the rigid plate about the roller to lift the wheel. The lifting device is then rolled on the surface to place the wheel at a desired position, and rotated until obtaining a desired rotational orientation.
