Engineering concepts l.jpg

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 concepts3 l.jpg

Engineering Concepts

  • Communicating ideas

  • Interpersonal skills

    • Teamwork

    • Group skills

    • Dialog persuasiveness

    • Attitude

    • Work ethic

(VCSU Unit #2, 2006)


Engineering concepts4 l.jpg

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 l.jpg

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 process6 l.jpg

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 process7 l.jpg

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 process8 l.jpg

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 process9 l.jpg

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 process10 l.jpg

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 process11 l.jpg

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 process12 l.jpg

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 process13 l.jpg

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 process14 l.jpg

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 l.jpg

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 l.jpg

Technological Literacy

  • Understanding our world

  • Ability to use, manage, assess and understand technology

(VCSU Unit #2, 2006)


Engineering design process vs technological literacy l.jpg

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 literacy18 l.jpg

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 literacy19 l.jpg

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 literacy20 l.jpg

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

(VCSU Unit #2, 2006)


Standards l.jpg

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)


Standards22 l.jpg

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.

(VCSU Unit #2, 2006)


Standards23 l.jpg

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.
