The Stack Parking System is a smart, mechanical parking solution designed to maximize vehicle storage in limited spaces. It utilizes vertical space to allow multiple vehicles to park in the footprint of a single traditional parking spot. These systems are ideal for residential complexes, commercial buildings, and urban parking facilities.

Dependent System (2-Level)
A 2-level dependent parking system allows two vehicles to be parked vertically, one above the other, using a shared platform.  
Advantage:
- Doubles parking capacity in compact areas  
- Cost-effective and space-saving  
Disadvantage:  
- The lower car must be moved to retrieve the upper one  
- Requires coordination between users

Independent System (2-Level)
The 2-level independent parking system also stacks two vehicles but allows each car to be accessed and retrieved independently.  
Advantage:
- Each car can be parked or retrieved without moving the other  
- Saves time and increases user convenience  
Disadvantage:
- Higher initial investment and installation complexity  
- Requires more vertical clearance or pit space (for underground types)
