Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual handling of heavy tires and wheels during maintenance requires excessive strength and can lead to physical strain and injuries for technicians, necessitating a solution for remote and labor-free tire removal and replacement.
Innovation Solution
A tire lifting device with a frame, hydraulic jack, and remote control operation, featuring rollers for tire rotation and adjustable guides to secure and lift tires, allowing the device to carry the full weight of the tire and wheel, eliminating manual labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual handling of heavy tires and wheels is performed by technicians, then the service can be completed, but excessive strength is required and physical strain and injuries occur
Solution Approach 1:
The patent replaces the manual mechanical system with an automated mechanical system featuring hydraulic jacks for lifting, motorized rollers for rotation, and automated guides for positioning. This substitution eliminates the need for technician strength while maintaining the tire removal and installation function.
Solution Approach 2:
The device enables the tire and wheel assembly to serve itself through automated mechanisms. The hydraulic system automatically lifts, the rollers automatically rotate to position lugs, and the guides automatically secure the assembly, requiring no manual intervention for the heavy lifting and positioning tasks.
2Extent of automation
If a hydraulic jack and roller platform are used to lift and rotate the tire, then manual labor is eliminated, but device complexity increases
Solution Approach 1:
The device integrates multiple functions into a single unified system: the hydraulic jack provides both lifting and positioning functions, the roller platform provides both rotation and support functions, and the guides provide both alignment and securing functions. This multi-functionality reduces the need for separate devices while achieving high automation.
3Reliability
If tire guides are extended to secure the tire during removal, then the tire is stabilized, but the device occupies more space and requires adjustment
Solution Approach 1:
The tire guides are designed as dynamic, adjustable components that can extend and retract based on operational needs. During tire removal, the guides extend to secure and stabilize the tire; during storage or movement, they retract to minimize space occupation. This dynamic adjustment is controlled by the automated system.
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
Enables efficient and effortless tire removal and replacement, reducing physical strain on technicians and improving safety by automating the process with remote control operation and hydraulic power.
Implementation Method 1
a hydraulic jack, which is configured to raise or lower a roller stand receiving the wheel and tire
Implementation Method 2
The roller stand further comprises rollers that allows the tire and wheel to spin freely
Implementation Method 3
The device further comprises dual action cylinders to hold the tire guides upright during use and retracts the tire guides when the load such wheel and tire, is to be removed from the device

AI summary
A tire lifting assembly used to remove and replace a wheel and a tire on a vehicle is disclosed. The tire lifting assembly is configured to take the weight of the wheel and the tire when the service technician removes or replaces it thereby eliminating the need for manual efforts from a service technician. The assembly is rolled under the mounted wheel and tire and quickly adjusted to secure the wheel and tire by using a roller platform. A scissor jack mechanism is used to adjust the height of the roller platform which allows the rotation of the tire during the mounting procedure.
