Elevated ParkingSystem Design
Tuesday, May 4, 2010
Objectives
develop an elevated parking system to save ground space
the system should allow user to enter and exit their vehicle with ease
Tuesday, May 4, 2010
Conceptual Design 1
two levels to park
first car parked at base level
mechanism will lowers to allow second car to park
system comprise of motor, pulley, and cable
gear reduction ratio will be used to create more torque

Conceptual Design 1
Advantages:
simple mechanism
easy to maintain
Disadvantages:
require 2 floors of space

Conceptual Design 2
two levels to park
elevator attached with sliding mechanism
mechanism will raise the car to allow second car to park
manual controlling mechanism

Conceptual Design 2
Advantages:
easy sequence mechanism
Disadvantages:
complicated mechanism; 2 motions are required
lots of parts required

Conceptual Design 3
when parked, the car will be slide to the lift
if the upper car want to exit, the lower car must get out first
mechanism will raise the car to allow second car to park
manual controlling mechanism

Conceptual Design 3
Advantages:
require 2 stories ground space
Disadvantages:
complicated mechanism; 2 motions are required
complicate working sequence
