Introduction

• How many times have you been stuck in traffic on
  the highway wondering what the hold up is?
• Well, usually the cause of the traffic is an
  accident.
• Unfortunately, in some cases, as one passes by
  the scene of an accident, he can see cars flipped
  over, possibly crushing whoever is inside.

3

• Our safety improvement for automobiles is a roll
  cage.
• Although already used in race cars, our
  improvement will make roll cages standard in all
  vehicles.
• These rolls cages will be incorporated into the
  frame of a car, and therefore will be installed
  during the initial production process of all
  automobiles.

4

• These new standard roll cages will be constructed
  with titanium, rather than steel (steel is
  standard for roll cages in race cars).
• Although more expensive, titaniums strength to
  weight ratio is greater than that of steel, so
  the bars can be thinner and still be as strong,
  if not stronger than steel. This is essential
  due to the fact the roll cage will be installed
  within the frame of the car.
• The safety of people and their families will be
  worth any extra money that the roll cage will
  cost.

Estimated Cost of Innovation

• Dimensions of a average size car (Ford Taurus)
• Width 73 in
• length wheelbase 108.5 in
• height 57 in
• total length of titanium bar needed for one
  car 1037in
• size of tubing 2in outer
  diameter
• 
  
  .75in thickness
• Weight of titanium
• Tube weight( .1281 thick dia2)1037
  in 398.5191 lbs
• Cost of titanium per pound 13
• Total cost of titanium used
• 400 lbs 13/lbs 5,200
• Estimated man hours to assemble cage 14
• Cost per hour of metal fitters 14.99
• Cost for assembly 210
• Total cost of cage 5,410
• Number of new autos produced 2003 17,000,000

Monetary Value

• The calculable costs of motor-vehicle crashes are
  wage and productivity losses, medical expenses,
  administrative expenses, motor vehicle damage,
  and uninsured employer costs.
• The following chart compares all costs associated
  with fatal accidents as a result of rolling to
  nonfatal accidents as a result of rolling.

• total cost of people dying in a rollover motor
  vehicle accidents in 2003 49,201,000,000
• Total number of nonfatal accidents in 2003
  179,438
• Average economic cost of
• Non fatal injury 45,500
• Property damage 8,200
• Average comprehensive cost of nonfatal accident
• Incapacitating injury 181,000
• Non incapacitating evident injury
  46,200
• Possible injury 22,000
• No injury 2,000

• Value
• The cage will reduce deaths by half and lesser
  injuries of nonfatal crashes by two thirds. For
  the estimated 91 billion dollars which the roll
  cage will cost consumers, consumers will save 25
  billion dollars in fatal accidents. Consumers
  will also gain 14 billion dollars on nonfatal
  accidents. The roll cage will cost consumers a
  total of 62 billion dollars per year. With 300
  million consumers in the USA the average cost to
  each person is a little over 200 dollars.

Non-Monetary Value

• When it comes to safety features on automobiles
  there is just as much emphasis on non-monetary
  value as the monetary.
• Customers pay extra and are attracted to
  companies that can provide them with a piece of
  mind that they are as safe as possible in their
  cars.

10

• A company choosing to utilize the roll cage
  technology would be capitalizing car buyers
  desire for increased safety.
• Car makers have been making every effort to
  reduce roll over accidents in these vehicles.
• Although SUVs roll more commonly than other
  vehicles, this feature can be applied to any
  model of automobile. Sport cars and family sedans
  can benefit from the peace of mind extra safety
  provides.
• The technology of the product is simple, and can
  be easily implemented into a companys
  production. This product is appealing for the
  company and the customer, and the benefits go
  beyond the monetary value.

Creativity Techniques

• We began with brainstorming and several bizarre
  ideas were thrown out.
• Subsequently, with good feedback and support
  among ourselves, we were able to slowly develop
  the ideas into actual innovations we could use to
  improve automobile safety.
• Finally, we made the decision to improve the
  support system within automobiles.
• We would implement a roll cage into all vehicles.

12

• Once again, we had to brainstorm to figure out
  what innovative material we could use to
  construct the roll cage (steel is used in roll
  cages in race cars.
• Some people even suggested crazy ideas such as
  bamboo.

• With the proper feedback and support, we were
  able to scale the radical ideas down into useful
  ones.

13

• Finally, we used four box analyses to analyze
  our remaining choices.
• We compared our choices based on cost, need,
  weight, and accessibility.
• In the end, we decided titanium would be our best
  bet, based on its strength to weight ratio.

14
Conclusion

• The cost of constructing a titanium roll cage in
  all vehicles will be expensive.
• We feel, however, that the total monetary value,
  combined with all non-monetary value of having
  the roll cage in vehicles far outweighs the cost
  of producing roll cages within automobiles.
