INTRODUCTIONObjectives:Designing a shoe rack that’s :

Cheap

Eliminates problems of bad odor and disorganization.

Stores many shoes without causing a mess.

INTRODUCTIONBackground• 33% of the shoe owners have trouble finding the

space to store all of their shoes collection. In order to solve the problem, shoe rack was invented as a storage unit designed to store shoes.

• There are various types of shoe rack designed based on the customer’s need such as under the bed shoe racks, over the door shoe racks, free standing shoe racks, hanging shoe racks and rotating shoe racks.

The shoe rack was divided into three compartments :

Compartment Description

Electric Compartment

Made so that all the electronic parts (motor, gear, humidifier, and fan) are put together in the same place. Which makes it easier to maintain.

Rotating Compartment

This compartment is where the rotating part of the shoe rack is placed, and the shoes are stored.

Accessories Compartment

This is where all socks and accessories are stored. It helps the user because it stores everything in one place

18Material Selection

Polymethyl Methacrylate (Perspex):• Good impact strength.• High service temperature.• Low costAluminum:• Cost effective• Corrosion resistance• Light weightWood:• Durable• efficient


19ENGINEERING ANALYSIS

In order to determine the best motor to be used for the shoe rack, the following formula is used:

speed of rotation= Where, 2πr = circumference of the wheel

Load on the bars carrying the shoes are calculated using the formula:

Load on the chair is calculated using the formula:


21Dehumidifier

Rock salt was chosen for the dehumidifier. In order to absorb the moisture content of air in the shoe rack. Rock salt can be easily obtained and can even be made at home.
