The primary function of a hair dryer is to blow hot air over damp hair to speed the evaporation of water to dry the hair.

Hair dryer can be further improved with styling, combs , hairbrushes during drying to add tension, lift and hold.

Customer needs>>

1. easy to use

2. light weight less than 2.5 pounds

3.with hot and cold wind

4. low price

5. easy control

6. quick drying

7. hair will not break at the time of using

8. motor does not overheat quickly

9. does not take too much electricity

>>these are the basic customer needs a hair dryer should provide. a customer usually look for good performence, quick dry function and a stable air flow. people who has long hair concern about diffuser that allow to style of their hair, but will not get in fan at the time of drying. some people like foldable handle. mainly who like to travel.

some people also concern about sound and a stable air flow.

Target market>>

the theme of hair dryer is "be stylish" so product will attract more people in big cities. the new hair dryer target to design for young people who are seeking for a user friendly dryer with good performance and a low price.

performance requirement>>

the minimum flow rate the dryer fan must provide to keep the average air tem. below 60 c. about .047 m3/s volume of air measuring 1m*1m*2.8m.

diffusers are great for people who have curly hair. which can help to define curls and add volume. concentrators narrow the hair dryer air flow to blow air directly on hair for sleek and smooth styles.

surface temperature should not exeed beacause that can damage dryer body or harm the user. a hair dryer temperature should be in limit. it should not exceed 20 C.

hair dryer exit temperature shold not exceed 60 C. because that can damage hair. because drying hair with 47 C is enough.
