2. Statement of the problem

Design a practical remote control that use solar

operator. This would allows the users to save money and

time (economic).

3.Introduction:The normal remote control can waste

time and money by changing its battery.

The solar cells can convert the energy in light into electrical energy.

This project solves the normal remote controls problem by using "the solar remote control”.

7.Criteria For Successful Design Small size.

Low cost.Light weight. Nice appearance.Strength of material. Production simplicity. Convenience of use.Safety.Transmission range.Light-reflecting buttons .Can be used by one hand .7

8.Problem Definition:Design a practical remote control that use

solar operator. The maximum price of the remote should not be more than 80 SR , maximum thickness 3cm, maximum width 7 cm and maximum length 20cm . It’s size should be made of strong material and mass is not exceed 300g .The remote must be has a long transmission range. The remote should be easy to use and has long life . The remote is universal remote control .

10.Human factor

A. Anthropometric Factors :Dimensions of human hand :

1. Hand length = 17.9cm2. Hand width = 8 cm 3. Thumb length = 7 cm

Dimensions of solar remote control :

1. Length = 18 cm 2. Width = 4.5 cm3. Thickens =2.5 cm

16

18

B. Ergonomic Factors :Arrange the buttons according to the use of them , so the most buttons

repeatedpress will be made :

1. Close to the thumb 2. Different size

These buttons are : Channel up –Channel down Sound up – Sound down

D. Psychological Factors: Make the buttons shape according

to the function of them :1. Channel up

2. Channel down

3. Sound up

4. Sound down Make on/off button with red color
