The Iron Man Movies and the Engineering Design ProcessBillionaire 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.

1st PrototypeMark 1 Version

3rd PrototypeMark 3 Version

Notes SPI 0807.T/E.1 (Prototype Testing)SPI 0807.T/E.2 (Eng. Des. Process)

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?

Engineering Design Process Science

Which step of the engineering process is this?

STEP 4:Test and Evaluate

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.

NotesSPI 0807.T/E.3

Intended Benefits and Unintended Consequences

Science

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

What is the intended purpose/benefit?

Another Example: Automotive Technology

(cars and trucks)

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.

NotesSPI 0807.T/E.3

Intended Benefits and Unintended Consequences

Science

Example: Cell phones and Cars -One unintended consequence is wrecking your car while talking or texting while driving.

Cell phones and cars were not designed to cause traffic accidents

Intended benefit -cell phones were designed for communicationIntended benefit -cars were designed for transportation
