Motorized Vehicle Jack With Magnetized Sockets for Fast Tire Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle jacks require manual labor to lift vehicles and remove/reinstall lug nuts, making tire changes laborious, time-consuming, and prone to lug nut scattering.
Innovation Solution
A motorized vehicle jack with a lift plate and a telescoping, pivotal shaft equipped with motorized, magnetized sockets that automatically raise/lower the vehicle and remove/reattach lug nuts, using a planetary gear assembly for torque and a foot switch for operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual lug nut removal and reinstallation is used, then the device complexity is low, but the productivity is reduced and time is lost
Solution Approach 1:
The patent combines the lug nut removal tool with the jack structure, integrating multiple functions into a single device. The telescoping shaft with magnetized sockets is incorporated into the jack body, allowing simultaneous lifting and lug nut management operations, thereby improving productivity without requiring separate tools
Solution Approach 2:
The jack is designed to perform multiple functions: vehicle lifting, lug nut removal, lug nut retention, and lug nut reinstallation. The magnetized sockets can both remove lug nuts and retain them during tire replacement, eliminating the need for separate tools and significantly reducing tire change time
2Loss of time
If manual lug nut handling is used, then the device complexity is low, but the loss of time increases due to scattering and manual reattachment
Solution Approach 1:
The magnetized sockets automatically retain lug nuts through magnetic attraction without requiring manual intervention. The lug nuts are held in place by the magnetic field of the sockets, eliminating the need for manual handling and preventing scattering, thus reducing time loss while maintaining simple operation
Solution Approach 2:
The magnetized sockets act as an intermediary between the lug nuts and the user, providing automatic retention through magnetic force. This intermediary mechanism prevents lug nut scattering and facilitates easy reattachment by simply bringing the sockets near the wheel, significantly reducing the time required for lug nut management
3Ease of operation
If motorized lifting is implemented, then the ease of operation is improved, but the use of energy increases
Solution Approach 1:
The patent extracts the motorized lifting function from the overall jack system, allowing the lifting mechanism to operate independently with its own motor. This separation enables the motor to be optimized for lifting operations only, improving ease of operation while managing energy consumption through dedicated motor control

AI summary
An improved vehicle jack includes a motorized lift plate that either raises or lowers a vehicle when the motor is operated in one of two directions. The jack also includes a lug-nut removal tool formed of a telescoping, pivotal shaft having an adjustable head at an upper end. A plurality of motorized, magnetized sockets are positioned on the head for tightening and loosening lug nuts. Accordingly, the lift plate is activated to raise the vehicle, and the sockets are properly positioned to automatically remove, retain, and reinstall the wheel's lug nuts.
