I1-6 8
Constraints on the Engineering Design Process
(A constraint is a limit or restriction)
Safety – is the product safe to use/construct?
Reliability – will it work consistently over time?
Cost – is it affordable?
Quality Control – does it meet customer requirements?
Environmental Concerns – does it harm the natural or human environment negatively?
Manufacturability – can it be made?
Maintenance – how easily can it be maintained or upheld?
Ergonomics – how efficiently can the human body utilize it?
Use the image of NASA’s new lunar service vehicle as an example for the constraints.

Students have seen this slide before. I suggest before clicking the 9 core technologies onto the screen, identify parts of the shuttle and have the students identify which core technology it is.
Robot boom arm that sticks out of the shuttle bay – Mechanical
The frame of the shuttle doors and wings – Structural
The battery power supply used for lights and other energy – Electrical
The computer systems used to store and transmit information – Electrical
Plumbing system in the shuttle – Fluid
Lights and video screens – Optical
Air conditioning / heating system – Thermal
Food processors, human waste disposers – Biotechnology
The modified plastics, metals, and ceramics - Material
Technology Systems

IOT POLY ENGINEERING
I1-6
Classwork / Homework
Partner exercise - articles about particular technology systems (i.e. Hubble, Maglev Train, etc.) and students must:
Describe the system outputs – what are the desired/undesired outputs?
Describe the operation of the system in terms of the 9 core technologies.
Answers should be written up. 3 or 4 groups will be chosen at random tomorrow to give presentation. 3-minute maximum. Teacher will ask questions.
