Solution Overview
Problem
Existing vehicle lift systems using multiple hydraulic cylinders often experience hydraulic fluid pressure imbalances, leading to uneven lifting rates and potential vehicle instability or wear in moving parts.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple hydraulic cylinders are used to actuate the vehicle lift, then the lifting capacity and stability are improved, but the hydraulic fluid pressure becomes unbalanced leading to uneven lifting rates
Solution Approach 1:
A synchronizer device is introduced as an intermediary component between the hydraulic pump and multiple hydraulic cylinders. The synchronizer includes a piston that divides the hydraulic fluid flow, ensuring equal pressure distribution to each cylinder. This mediator resolves the pressure imbalance issue while maintaining the benefits of multiple cylinders for lifting capacity and stability.
Solution Approach 2:
The synchronizer modifies the hydraulic fluid pressure parameter by using a piston mechanism that equalizes the pressure distribution across multiple output lines. By changing the pressure parameters through the synchronizer's internal geometry and piston movement, the system achieves balanced pressure delivery to all hydraulic cylinders, preventing uneven lifting rates.
2Speed
If hydraulic fluid pressure is increased to improve lifting speed, then the lifting efficiency is improved, but the wear and distortion of moving parts increases
Solution Approach 1:
The synchronizer enables controlled pressure parameter changes by using its piston mechanism to distribute hydraulic fluid evenly. This allows the system to operate at higher pressures for improved lifting speed while maintaining balanced load distribution across all cylinders, thereby reducing uneven wear and distortion of moving parts through consistent pressure application.

Function Achieved in This Case
The synchronizer maintains consistent hydraulic pressure across all actuators, preventing uneven lifting and reducing wear, ensuring stable and balanced vehicle lifting operations.
Implementation Method 1
A piston in the synchronizer separates an input side of an interior of the synchronizer, which is in fluid communication with the input port, from an output side

AI summary
An apparatus includes a housing, a piston, an input cavity, a first actuating shaft, a first output cavity, and a second output cavity. The housing comprises an input port, a first output port, a second output port, a first end, a second end, a first wide wall having a first internal surface, and a chamber at least partially defined by the first end and the first internal surface. The piston is able to actuate along the first internal surface of the first side wall. The input cavity is in fluid communication with the input port. The first output cavity is in fluid communication with the first output port. The second output cavity is in fluid communication with the second output port. The first actuating shaft is fixed to the piston and helps fluidly isolate the first output port from the second output port.
