Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable vehicle jacks require manual operation, which can be tiring and dangerous, and often rely on vehicle battery power, potentially depleting or damaging the battery.
Innovation Solution
A battery-operated vehicle jack with an electric motor and lead screw mechanism that allows for easy lifting and lowering of vehicles with minimal user effort, using a base, lift arm, and crank arm configuration, powered by a battery to reduce manual adjustment and battery dependency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used, then device complexity is reduced, but ease of operation deteriorates and user effort increases
Solution Approach 1:
The patent replaces the manual mechanical operation system with an electric motor-driven system. The electric motor receives power from a battery and actuates a lead screw mechanism to automatically raise and lower the lift arm, eliminating the need for manual cranking or lever operation while reducing device complexity through automated control.
2Ease of operation
If vehicle battery is used to power the jack, then ease of operation improves, but reliability deteriorates due to battery depletion or damage
Solution Approach 1:
The patent extracts the power source from the vehicle's battery system and uses a separate, dedicated battery specifically for the jack operation. This isolation protects the vehicle battery from depletion or damage while maintaining the ease of operation provided by electric power actuation.
3Ease of operation
If electric motor with lead screw is used, then ease of operation improves, but device complexity increases
Solution Approach 1:
The patent employs an electric motor to replace manual mechanical input, driving a lead screw mechanism that converts rotational motion to linear motion for lifting. This substitution of manual operation with electric actuation significantly improves ease of operation while the integrated design of the motor and lead screw assembly keeps the overall device complexity manageable.
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 safe lifting of vehicles with reduced user effort, providing a stable and sturdy lifting platform that can lift vehicles up to 1.5 tons in less than 90 seconds, with increased mechanical advantage and self-locking features to prevent unwanted movement.
Implementation Method 1
a lead screw threadably engaged with the drive nut, and an electric motor configured to receive power from the battery and operable rotate the lead screw to adjust an angle between the lift arm and the crank arm
Implementation Method 2
an electric motor configured to receive power from the battery and operable rotate the lead screw

AI summary
A vehicle jack, such as a battery-operated vehicle jack is provided. The jack includes a base, a lift arm, a crank arm, an actuator coupled to the lift arm and an electric motor to actuate the actuator. The lift arm includes a first end that engages a load and a second end that is moveably coupled to the base. The crank arm includes a third end that is pivotally coupled to the base and a fourth end that is pivotally coupled to the lift arm between the first end and the second end. The electric motor actuates the actuator to move the second end of the lift arm relative to the third end of the crank arm to cause a vertical movement at the first end of the lift arm between a lowered position and a raised position.
