2. INTRODUCTION Problem statement: Group 68
Existing shoe racks have limited storage capacity.
Limited storage leads to the shoes becoming unorganized.
Other problems such as disturbing view and unpleasant odors are caused by the storage of too many shoes in small space.

4. INTRODUCTION Background Group 68
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.

11. The shoe rack was divided into three compartments :
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

19. ENGINEERING ANALYSIS Group 68
In order to determine the best motor to be used for the shoe rack, the following formula is used:
speed of rotation= 𝑀𝑜𝑡𝑜𝑟 𝑆𝑝𝑒𝑒𝑑 2𝜋𝑟
Where, 2πr = circumference of the wheel

21. Dehumidifier
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.
