Engineering Concepts
Engineers are problem solvers Solving problems for humanity Use math, science, tools &
materials Some say, “Design without math and
science is tinkering.” Is tinkering OK? Use the engineering design process
(VCSU Unit #2, 2006)
Engineering Concepts
Communicating ideas Interpersonal skills
Teamwork Group skills Dialog persuasiveness Attitude Work ethic
(VCSU Unit #2, 2006)
Engineering Concepts
Coping with change Technological literacy Brainstorming abilities Appropriate technology How technology and engineering
affect the environment
(VCSU Unit #2, 2006)
Engineering Design Process
Design is the planned process of change
To end up with an intentional result Minimize trade-offs and control risk
(VCSU Unit #2, 2006)
Engineering Design Process
1. Identify the problem This appears to be simple but taking
the time to find the root problem is extremely important.
(VCSU Unit #2, 2006)
Engineering Design Process
2. Define or “refine” the problem Investigate to find out more info about
the problem A team effort is required Clarify with a design brief
This describes the limitations and requirements for the solution
(VCSU Unit #2, 2006)
Engineering Design Process
3. Gather information Don’t reinvent the wheel Find out what research has already
been done The internet is a great place to start
(VCSU Unit #2, 2006)
Engineering Design Process
4. Develop alternate solutions Critical step - first ideas are rarely best Brainstorming should be used No solution should be ignored at this
step The more ideas, the more probability
of success
(VCSU Unit #2, 2006)
Engineering Design Process
5. Select and refine the best solution The design proposal An evaluation process from the design
brief could be used Document your decision
(VCSU Unit #2, 2006)
Engineering Design Process
6. Express the design solution Through a sketch or drawing Verbal expression Text Mathematics equation 3D modeling on CAD
(VCSU Unit #2, 2006)
Engineering Design Process
7. Build a model or prototype of the solution This may contain the most
technological problems. Experiment with materials and
techniques
(VCSU Unit #2, 2006)
Engineering Design Process
8. Evaluate, revise, and refine the solution Analyze the solution for effectiveness
in solving the original problem. Run a performance test
(VCSU Unit #2, 2006)
Engineering Design Process
9. Communicate the solution Ideas need to be “sold” to the client Presentation must include prototypes,
models, or other form. The designer must know the design
and subject matter Upon approval, the idea can be
manufactured
(VCSU Unit #2, 2006)
Technology
How people modify the natural world to: Suit their own purposes Satisfy their perceived needs and wants
If you took away all technology, you would be standing naked in a meadow or forest
(VCSU Unit #2, 2006)
Technological Literacy
Understanding our world Ability to use, manage, assess and
understand technology
(VCSU Unit #2, 2006)
Engineering Design Process vs. Technological Literacy
Since Edison and the Wright Brothers, the engineering design process has shaped our world more than any other single process.
(VCSU Unit #2, 2006)
Engineering Design Process vs. Technological Literacy
The better we understand this process, the better we understand our world. (technological literacy)
This better prepares us to live and prosper
Our democracy works better
(VCSU Unit #2, 2006)
Engineering Design Process vs. Technological Literacy
Democracy only works with informed citizenry
Citizenry cannot be informed and ignorant of technology at the same time
(VCSU Unit #2, 2006)
Engineering Design Process vs. Technological Literacy
By understanding the engineering profession, we better understand the world
We can also make an informed choice about engineering as a career

Standards Standard 1: Students will develop an
understanding of the characteristics and scope of technology. Benchmark L. Inventions and innovations
are the results of specific, goal-directed research. Standard 4: Students will develop an
understanding of the cultural, social, economic, and political effects of technology. Benchmark I.Making decisions about the use of
technology involves weighing the trade-offs between the positive and negative effects.
(VCSU Unit #2, 2006)
Standards Standard 8: Students will develop an
understanding of the attributes of design.
Benchmark H. The design process includes defining a problem, brainstorming, researching and generating ideas, identifying criteria and specifying constraints, exploring possibilities, selecting an approach, developing a design proposal, making a model or prototype, testing and evaluating the design using specifications, refining the design, creating or making it, and communicating processes and results.

Standards
Standard 9: Students will develop an understanding of engineering design. Benchmark L. The process of engineering
design takes into account a number of factors.
