Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional jacking assemblies are used for vehicle lifting, then the vehicle can be raised to working height, but the mechanism lacks sufficient control and stabilization capabilities
Solution Approach 1:
The jacking assembly is divided into multiple independent cylinders (first cylinder for front wheel, second cylinder for rear wheel) that can be controlled separately. Each cylinder has its own actuator and control system, allowing independent adjustment and stabilization of different vehicle sections, thereby improving control capability without requiring a single complex monolithic mechanism.
Solution Approach 2:
The system employs dynamic control through actuators that can adjust cylinder extension in real-time based on vehicle position and stability requirements. The control system continuously monitors and adjusts the jacking process, transitioning from static positioning to dynamic stabilization, enhancing reliability during the lifting operation.
2Ease of operation
If manual jacking operations are performed, then vehicle lifting can be achieved, but user safety and convenience are compromised
Solution Approach 1:
The control system automatically monitors vehicle position, cylinder extension status, and stability parameters, making real-time adjustments without continuous manual intervention. The system serves itself by detecting conditions and executing corrective actions, improving user convenience and safety while maintaining appropriate automation levels.
Solution Approach 2:
Manual mechanical operation is replaced with an automated control system that uses sensors, processors, and actuators to perform the jacking function. This substitution eliminates manual safety risks while providing convenient remote or automated operation, though it increases the complexity of the control system.
3Reliability
If single-point jacking is used for tire changes, then the vehicle can be lifted locally, but stable support and control are insufficient
Solution Approach 1:
The system uses separate cylinders for different wheel locations (front and rear), allowing localized jacking at multiple points simultaneously. This segmentation provides stable support at each jack point independently while maintaining overall vehicle stability, avoiding the need for a single complex multi-point jacking mechanism.
Solution Approach 2:
The jacking assembly can perform multiple functions: single-wheel jacking for tire changes, multi-wheel jacking for vehicle maintenance, and adjustable height positioning. This multi-functionality provides stable support for various operations without requiring separate specialized equipment for each function.

AI summary
A vehicle jacking assembly for raising a vehicle includes a plurality of cylinders, each of which is configured to couple to a frame of a vehicle proximate to a respective wheel of the vehicle. The cylinder comprises a plurality of nested sections so that the cylinder is selectively extensible. An actuator that is coupled to the vehicle is operationally coupled to the plurality of cylinders and an electrical circuit of the vehicle. The actuator is positioned to selectively actuate the plurality of cylinders to extend the cylinders from the frame of the vehicle so that the cylinders contact a surface. The plurality of cylinders thus is configured to raise the vehicle.
