August 29, 2008 I1-5 With 1 partner: IOT POLY ENGINEERING I1-5 August 29, 2008 With 1 partner: Get out last night’s homework and critique the paper layout for correct formatting. Go through your assignments and critique them: Do the answers make sense? What are the good points made? What are the poor points made?

IOT POLY ENGINEERING I1-5 Closed-notes Quiz Take out a clean sheet of notebook paper, and correctly format the sheet for a quiz in this unit. List the late assignment policy. Besides your notebook, where can you find anything covered or handed out in this class? Create a graphic organizer that demonstrates the components of a technology system. Then, give a demonstrative example of each component. List and give an example for each of the 3 technology system processes.

Design Process I1-5 Design Principles Note: IOT POLY ENGINEERING I1-5 Design Process Design Principles Design is the result of a formal, sequential process. Design is mostly driven by profit motive and market. Design is the result of goal-oriented research. Designs must be continually checked, refined, and improved. Note: Design problems seldom arise in a clearly defined form. Design requirements sometimes compete with each other.

I1-5 Constraints on the Engineering Design Process 8 IOT POLY ENGINEERING I1-5 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.

I1-5 Constraints on the Engineering Design Process 8 IOT POLY ENGINEERING I1-5 8 Constraints on the Engineering Design Process (A constraint is a limit or restriction) With a partner, choose a technology system. Identify the likely constraints on the design of that system. List the generic 8 constraints, and fill in relevant ideas. When you call on some students to give their answers, ask them a few review questions as well. For example, “what makes that a technology system?” Or, “What is the need or desire that led to the design of that artifact?” One thing to keep in mind during this course is that there is not always 1 correct answer to a question. We’re not looking for “right” answers so much as we are looking for reasoned answers.

Core Technologies Core Technologies I1-5 9 Mechanical Structural IOT POLY ENGINEERING I1-5 9 Core Technologies Core Technologies Mechanical Structural Electrical Electronic Fluid Optical Thermal Biotechnology Material 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

Classwork / Homework I1-5 IOT POLY ENGINEERING I1-5 Classwork / Homework Create a chart that includes the 9 core technologies, LETTERED descriptions of each of the 9 core technologies, an everyday example not discussed in class so far clearly associated with that core technology. Have a great weekend. When the first bullet is read, mention a bunch of common technologies so that students can’t take an easy way out. For example, say, “iPod, t.v., cell phone, car, video games, computers, internet.” It frustrates them and will get them thinking outside their usual box.
