Statement of the problemUsing laptops for a long period causes it

to heat up too much, which leads to

slowing performance, damaging The

laptop, and decreasing laptop’s

life time. Therefore, cooling

is required.2

(1)

Introduction

People use laptops rapidly for long

durations. It causes the laptops to

have high temperatures. A proper laptop

cooler can cool down the laptop

and solve the problem.

Need Analysis

• Designing a group of fans.

• The product shouldn’t be expensive.

• The product has to be easy to operate.

• Reinforced plastic should be used in

the manufacturing.

• The product must have a long life-time.4

ObjectivesPrimary Objective :

To design a laptop cooler that can cool down the laptop effectively .

Secondary Objectives :

• Four fans should be used.• Has a law weight.• Foldable, portable, and easy to carry.• It should have USB ports.

Constraints• The used materials should be

internationally approved.

• The design should be safe.

• The used materials should be affordable.

• The used plastic in manufacturing can

be recycled.

• The used plastic shouldn't be toxic.

• Maximum price is 100 SR.

7

Criteria• Works quietly (no noise).

• High quality of used materials.

• Convenient cost.

• Warranty for two years.

• Easy to handle (comfortable, Portable).

• Stylish and modern look (thickness, size).

• Fits most laptop sizes (430*300 mm).

• Safety.

Problem Definition

To design a laptop cooler that can cool down the laptop

effectively by a group of fans . The design should be safe

and made with internationally approved materials. The

design has to be easy to operate and made with reinforced

plastic , with a long life-time. The cooler must work quietly

and functions by using USB port . The product shouldn’t be

expensive. In addition, it should have a stylish and a

modern look, also should fit all laptop sizes. 9

Morphological Analysis

Design 1 : plastic, rectangular, USB port, 4 fans, and 17 inch.

Design 2 : aluminum, rectangular, battery, 1 fan, and 14 inch.

Design 3 : plastic, square, electrical plug, 2 fans, and 19 inch.

Conclusion- In short, and in general, as a Laptop Cooler...

The following factors should be taken into account, as they contribute to the quality of the Product Design:

• The Need Analysis• The Morphological Analysis ( Criteria & Weight )

• The Human Factors ( Physiological - Anthropometric – Psychological )

- The more studies on the product design and taking those factors into account, whenever these factors contributed produces with high quality product design.
