Billionaire genius and weapons designer Tony
Stark is captured by terrorists, and they want
him to build a super-weapon. Instead he builds an
armored exoskeleton to fight them.

• Step 1 Identify a need
• Why did Tony Stark build the "Iron Man" suit?
• Step 2 Develop Possible Solutions
• What are some other options he could have built
  instead?
• Step 2A Pick the best design
• Do you think the "Iron Man" suit was the best
  design option?
• Step 3 Make a prototype
• Where and how did Tony build his prototype(s)
• Step 4 Test the prototype
• Where and how did Tony test his prototype(s)
• Step 5 Modify and re-test the prototype
• How did Tony modify his prototype to make it work
  better?
• Step 5A Use and/or sell the product
• Did Tony sell his Iron Man armor? How did you use
  it?

SPI 0807.T/E.3 Intended Benefits and Unintended
Consequences
Science
Notes
Intended Purpose/Consequences When a company
designs a new product, they are addressing a
need. (This is Step 1 of the engineering design
process). This need is connected with and is
essentially the same as the intended purpose.
The intended purpose/benefit is what the
engineers purposely include when designing some
product or process.

• Example
• Cell phones -The need being addressed is
  communication. Likewise the intended purpose is
  more effective communication.

Another Example Automotive Technology (cars
and trucks)
What is the intended purpose/benefit?

SPI 0807.T/E.3 Intended Benefits and Unintended
Consequences
Science
Notes
Unintended consequences are uses or results
that engineers DO NOT purposely include when
designing some product or process. these are
things that WERE NOT part of the design plan.
Example Cell phones and Cars -One unintended
consequence is wrecking your car while talking or
texting while driving.

• Intended benefit -cell phones were designed for
  communication

• Intended benefit -cars were designed for
  transportation

Cell phones and cars were not designed to cause
traffic accidents
