this is base on We are moving towards the age of Technology and intelligence,which are reaching sky high,inturn every thing around us are transforming according to the needs and requirement,and all this things are making our life better.

Each and every profession have its own contribution towards this drastic developement.Now if we look at the life of the software professional , we could find that they dedicate almost half of their life towards their work.They all work in a very tight schedule and lack space for their family,so in every weekend they try to spend some time with their family by going for some small outings to share happyness and to feel relaxed.

They use their private vehicle or a public transport for this purpouse,but both does not allow them to feel relaxed and interact comfortablywhile having a ride.

Prakriti is a project for a new segment of a private vehicle that helps to restore the balance in the emotional elements of daily life, this conceptual vehicle brings fun with relaxation and mutual interaction during the ride.

All in all its a vehicle that retains the smile on the face of a busy working family.

Lets have a look at the daily life of a software professional of India from an alien point of view. Here is a creature which wakes up in the morning takes bath , worships in front of a religious statue , eats and gets in to a box with wheels , after getting down from that , again he enters in to a very large geometrical shape where he finds other creatures like him working in front of a box , so called computer. working till evening then takes the same box with wheels and returnsback to the starting point of the loop.this continues through out , five days a week. Spending half of his like working and working.

Today most of the software professionals who are working are becoming emotionally detached from their families, because of their working schedule leading them becoming Artificial Parents of their children.This can also be seen from another point of view, children while growing mostly need mom or dad to share their emotions. It was seen in past but not visible now a days due to the work culture.

If we look around us , we can find a different vehicle for different purpose just like a casting of a movie,a different actor for different role. If we deeply observe a vehicle we can find that , it is constantly modifying according to its purpose of application. All in all vehiclea are having different Avatars.

As the world is moving towards the age of knowledge and technology, our surroundings had starting to become artificial. We started to loose trees and refreshing rains due to pollution , global warming and rapid urbanization and the day is not far when our next generation will ask us , how the nature looked like?

this is base on * There has been a healthy growth in the number of India's IT professionals over the1985-86, the number increased to 522,000 software and services professionals by the end of 2001-02.It is estimated that out of these 522,000 knowledge workers, almost 170,000 are working in the IT software and services exportindustry; nearly 106,000 are working in the IT enabled services andover 220,000 in user organizations.[26]

* The average working schedule of an IT professional in India for major software companies were reported as follows:

- TCS 9 hours a day.- Wipro 9.5 hours.- Accenture India (MNC) may soon increase to 9+ hours.- Infosys Technologies 9.15 hours- Satyam 9+ hours.

* The personal life of these IT professionals are already pretty harsh and stressful, will likely worsen even further. A very high percentage of software engineers report almost no time for social life outside office.

* One of the most blissful ways to relax and unwind is to potter around the garden with the song of a blackbird and the buzzing of insects in the background. It allows the mind to wander in the best possible space, then tidy up borders or lawn edging with the stresses of the day fading away.

* 25 % of global warming is due to the vehicles and its also a biggest consumer of petroleum products, causing an adverse affect on natural environment causing greenhouse effect.

1. Inside Handle Redesign: modify two hooks, delete the hole and create two snap-fits, also delete the rivet, reducing assembly time and manufacturing complexity. 2. Rod Secure Redesign: replace the current clip with a plastic rod clip to make the installation easier and save money 3. Striker Redesign: remove the metal spacer and the mylar washer, modify the base of the striker by making it thicker and adding coating on the surface that contacts the metal

Analogy

* Fluids will be used as the cushion for the seats because they can absorb vibrations .These materials can also absorb the vibrations that one might experience in a car. The fluid used will be Viscoelastic fluid: a relatively incompressible substance with viscous properties; viscous fluids do not flow as readily as water and include maple syrup and grease. (Otto Bock Floam, Sunrise Medical Quickie JayFlo are viscoelastic fluids.) [24]

The following complaints were selected for the Kano analysis:

• It is too difficult to close the door. A user has to apply too much effort to pull it fr om inside of the vehicle. Also, in the maximum

open position, the inside door handle is too far for an easy reach.

• The driver can accidentally lock the door when resting his elbow on the top of the inside trim panel.

And here are the questions asked:

• How would you feel if the door would close almost by itself once touched?

o Like (E)

• How would you feel if the door would require a strong pull in order to close?

o Don’t care

• How would you feel if the interior lock is moved from its current location (from on top of the trim panel, next to the inside handle)?

o Normal (L)

• How do you feel about having the door lock on top of the trim panel?

o Don’t like

The results of the questionnaire ar e showing clearly that the lock ing mechanism is a fairly Stat ic product. According to the co urse

material, we are in the right direction if we want to im prove the aesthetics and the ergonomics of the product, and reduce the cost –

these are typical activities for this status.

The Kano matrix shows that we need to focus on the effort required to close the door:

Opportunities for improvement

The door locking mechanism should be also analyzed for the following:

• Reduced cost.

• Reduced part cost for ease of assembly.

• Better appearance.
