A puzzle car parking system and a stack parking system both help increase parking capacity in limited spaces, but they work in different ways. A puzzle parking system uses a combination of vertical and horizontal platform movement, allowing vehicles to be moved sideways and up or down to bring a selected car to the parking or exit position. In comparison, a stack parking system mainly uses vertical lifting, with one vehicle parked above another. This makes a puzzle type parking system more flexible when multiple vehicles need independent access. In a puzzle car parking system, several platforms can move within the system, so the required vehicle can be brought to the ground-level position without necessarily moving every vehicle above it. A stack parking system generally has a simpler arrangement, but the vehicle placed on the lower position may need the upper vehicle to be moved before it can be accessed. Because of this, a puzzle parking system can be suitable for projects where higher parking capacity and better space utilisation are required.
