BACKGROUND INFORMATION• In 2012, 10,322 people were killed in alcohol-impaired driving crashes, accounting for

nearly one-third (31%) of all traffic-related deaths in the United States.

• Nearly 1.3 million people die in road crashes each year, on average 3,287 deaths a day.

• An additional 20-30 million are injured or disabled.

• More than half of all road traffic deaths occur among young adults ages 15-44.

• Each year nearly 400,000 people under 25 die on the world's roads, on average over

1,000 a day.

WHY DO THIS PROJECT

• Delphi is a leading global supplier of technologies for the automotive and commercial markets.

• To minimize the impact on the environment.

• To provide safer technology to decrease the number of accidents.

MISSION STATEMENT

We hope this design will let the drivers, the passengers around the world and even us have a safer ride and decrease the number of road accidents. As we all love the nature we are also trying not to cause any damage to the environment by using recyclable material.

The Design Process

LISTENING TO THE CUSTOMER• Needs of the customers were obtained

through an online survey we created and internal discussion within the group

• Better understand what customer wants in product

• Helps us to make a viable product for the market

SURVEY RESULTS: DRIVING WHILE TIRED• Part of our survey had questions on driving while

tired• Out of the 30 people who responded:

• 47% said that they are likely to drive while tired• 13% said that they have fallen asleep at the

wheel before• 80% considered driving while tired to be a

legitimate concern of safety for themselves and others

SURVEY RESULTS: DRIVING WHILE INTOXICATED

• Another part of our survey had questions on drunk driving

• 10% said that they are likely to drive while under the influence of alcohol

• 30% said that they have driven while under the influence

• 93% considered driving under the influence to be a legitimate safety concern for themselves and others

SURVEY RESULTS: OTHER CONCERNS• We asked respondents to give us other concerns for safety while driving

• Marijuana and general distractions were most commonly stated

• When asked how tiredness could be alleviated while driving:• 62% said that loud music would help• 76% said caffeine would help• 55% said cold air would help

79% felt that a device in the steering wheel that monitors heart rate would not be invasive

DETERMINING DESIGN ATTRIBUTES• Using the data from our survey and internal

group discussions, we came up with 4 “top-layer” attributes for our safety system

• Sensing method, response, problems detectable, and level of driver interaction

• Next, we created multiple second-layer attributes under each first-layer attribute

GETTING THE MOST IMPORTANT NEEDS• We came up with many customer needs• Wanted to get the top 10, however • “extraneous needs,” or unviable design

choices due to economic constraints, etc. must be taken out

• To accomplish this, we used the analytical hierarchy process (AHP)

0.242)4.7) Efficient (0.012, 0.100)

 

OBTAINING THE TOP 10 NEEDS• We used an AHP table to determine the top

10 initial second-layer attributes • These 10 were selected based on their weightings• After this, we put these 10 into an AHP table and

determined the top 5 second-layer attributes

TOP 5 ATTRIBUTES• Here are the top 5 attributes and their

weightings

DESIGN CONCEPTS

• Now that we got the top 5 attributes, we had to think of some concepts that might be present in the final design

• To do this, we went through the process of concept generation

WHAT IS THE PROBLEM?

• In concept generation, it was important to remind ourselves of what the problem we are trying to solve is

• Doing this focused the group on creating viable concepts that would be pertinent to the desired design

• For us, the problem was making a viable safety system for automobiles

SEARCHING EXTERNALLY• For possible inspiration on a design we could

make, the group read literature on heart monitors, how the heart’s beat changes when tired, breathalyzers, etc.

• The group also read up on patents that are relevant to our ideas, as to make sure we were not infringing on others’ property

SEARCHING INTERNALLY• After reading a lot of material, we discussed

internally as a group as to what material was useful and could help us make a good design

• How could these ideas be implemented into the concepts we had?

• It was important to have open discussion within the group so that all possible ideas were heard and considered

AFTER CONCEPTUALIZING

• When we had our concepts, it was wise to classify them

• This was done to make the concept selection process easier

• To accomplish this, we used a classification tree and concept selection tables

FACTS AND STATISTICS

- Underreported- No Tests- It is hard for Cops to notice

drowsiness in drivers.- 10-30% of all crashes.

DIFFICULTIES??

WHAT WE HOPE TO ACHIEVE:

- Safety - To Meet Delphi’s Goals - Prevent Drowsiness Accidents Rates.

THANK YOU!!
