Technology as a System
Components:
Goals
Humans develop technology to meet needs
Each artifact meets more than one goal
Inputs
Resources that go into a system and are used by it
Processes
Design Process, Production Process, Mgt. Process
Outputs
Technological systems are designed to produce specific outputs.
Manufactured products, constructed structures, communicated messages, transported people or goods.
Feedback and Control
Using information about the outputs to regulate the system.
NEED / DESIRE
DESIRED / UNDESIRED

6. 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.

13. 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.

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.

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
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.
