Chemical Engineer-Unicamp-Brazil
• Time wasted in traffic: continuous grown in big cities -> Idle passenger time
• Only in São Paulo city, Brasil-> 1500 brand new cars/day
• Women’s opinion is decisive when choosing the new vehicle. Also, they’re responsible for 42% of total new vehicles aquisitions.
• For 88% of women, hair is essencial for personal and profession satisfaction.
Observed Facts:
• Hair Production demands long times.
• In São Paulo city, Brasil, average 2h42’/day (Ibope, 2010)
Proposal:
Hair Beauty devices adapted into vehicles, making use of engine and exhaust duct wasted heat.
• Hair Dryer
• Flat Hair Iron
• Curly Hair Iron
(Baby liss)
Actual devices:
Average device power: 1800 W

Operation:
Hair Dryer:
Just transport heated air to the desired location.
No internal electrical resistance. Fan is onboard the vehicle -> silenced operation, no electric chock risk.
Without electrical power limit, can deliver more thermal power then the ordinary electric hair dryer, making it the favorite.
Operation:
Flat Hair Iron
(Baby liss): Only transports
heated air. No electrical resistance, doesn’t get burn if someone accidentally forget to turn it off.
Operation:
Curly Hair Iron:
Product Suggestion:
Accessible for all passengers.

Useful moments and places
Useful moments and places:
Child on rain:
-> cold/flu
Useful moments and places:
Taxi
Long distance buses.
Useful moments and places:
• Make use of time wasted in traffic
• People who live far away from work
• After shower in the gym, make hair production on-the-go
• Morning shower without having to dry out at home
• Last minute accidents (water spilled from window, drizzle, etc)
• Child that took rain
• Taxi
• Long distance buses
• Make possible having the hair washed with a higher frequency
• Recovering part of delayed time – professional or personal
• Give possibility for a better use of time (time is luxury)
• Reuses wasted thermal energy - Ecological
• Home energy saving – avoid the use of electricity at home.
• Make possible to last minute hair style fix, being aways in the desired look.
Advantages
Sustainable product
• Make possible to get the hair hashed more frequentily.
• The electrical resistance will hardly ever get wasted – there’s no need for periodic change.
• The heating mechanism is central, mounted in the vehicle, not into the tail device. No risk of electric chock.
• In São Paulo city, 1500 brand new cars, every day
Foreseen:
• Women represent 42% of this market - 630 cars/day
• In launch : 2% of this share= 13 cars/day= 378/month
• In 6 months, 4%: 756 cars/month
• In 12 months, 9%: 1700 cars/month
• In 18 months, 17%, 3213 cars/month
• In 2 years, 32%: 6048 cars/month (72k/ano)
Foreseen
*Without correction of 1500 new cars/day
**32% = share of women that take confort as a must-have item when choosing the vehicle.
***Forecast only for São Paulo city, Brazil.
****Foreseen that only women would buy the accessory.
• Nacional demand, in 24 months: 170 k/year
• (base year: 2009: 3.18 mi cars/year)
(Higher demand from customers that live in big urban centers with high traffic jam index)
*****Without considering retrofit in existing vehicles.
Suplliers
• Automakers: engineering
• Hair Dryer, Flat and Curly hair iron: existing brands can make ajustments in their products and increase their portfolio. Final product would bring the automaker logo.
• Heat recovery: heat exchanger, thermal insulation air transport ducts, temperature sensors, electrical resistance, system control (control valves acting as a funciont ot the gas temperature).
• All new parts already have supplies for automarkers. If there isn’t the exact product, a simple adaptation would do.
