  1. Chapter 1 DESIGN & ENGINEERING

  2. WHAT IS TECHNOLOGY?

  3. Technology takes place when people use their knowledge to extend their abilities, satisfy needs and wants to solve problems

  4. What are some examples of technology that use…everyday?Everyweek?At school?

  5. DEVELOPMENT OF TECHNOLOGY Demand for more products increased, new production technologies and processes answered the demand Agricultural Age- based on growing crops and raising livestock Industrial Age- based on manufacturing Information Age- based on knowledge

  6. Products of technology that moved people from Agricultural Age to Information Age…was the result of Design

  7. DESIGN- the process of creating things by planning

  8. 2 ways to design: • Invention- new idea • Innovation- improvement • Example- CD player innovation of the phonograph (Edison)

  9. The Design Process:

  10. The Design Process Steps Step 1- Identify a need or problem a. state the problem b. know the criteria c. know the constraints Ex. Problem- design an athletic shoe for hardwood floors Criteria- must grip hardwood floors Constraints- shoe tops- leather - cost < $20 CAN YOU THINK OF A DESIGN PROBLEM?

  11. Step 2-Gather Information -research what others have done -Talk to people- feedback WHAT OTHER THINGS CAN WE DO TO GATHER INFORMATION?

  12. Step 3- Develop Possible Solutions - should be many ideas- never 1 solution - brainstorm ideas - pros/cons for each idea - principles and elements of design helpful

  13. Step 4- Model the Solution - 2-D/pictorial drawings - scale models - functional models- work, but don’t look like final - prototype- working model - computer simulation

  14. Step 5- Test and Evaluate the Solution - does it do what its supposed to? - will it last as long as needed? - is the cost within acceptable limits? - does it stay within the criteria &constraints?

  15. Step 6- Refine the Solution - are changes needed?

  16. Step 7- Communicate your Ideas - prove your design is worthy - make a presentation - make drawings, charts, prototypes

  17. Types of Engineers • Manufacturing- find the best way to produce a product • Goal- increase productivity • Design & organize the placement of machines on plant floor • Develop the sequence of processes used to transform materials into products

  18. 2. Aerospace- new types of aircraft - focus on engine design, frame of aircraft, and the control systems 3. Materials- developing materials with specific properties that meet a manufacturer’s needs -strength, conductivity and hardness

  19. 4. Environmental- design cleaner production methods - design systems to clean up polluted sites 5. Computer- spin- off of electrical - can specialize in hardware or computer design -install and maintain large computer systems

  20. Your Turn • Choose a type of engineer to be. • What would you do as that type of engineer? • Would you invent something? • Would you innovate something? • How? • Write down and sketch out what you would do! • Pages 30, 31, and 32

  21. ARCHITECT • Description • plan, design and oversee the construction of may types of buildings • Work closely with clients, engineers and building contractors • Prepare scale drawings • Ensure projects meet building codes and laws

  22. Qualifications • math and science background • Drafting and problem-solving skills • Bachelor’s degree • 3 years experience and pass an exam • Require license from the state • High school- math, science, design, history, archeology

  23. Job Outlook- good- depends on construction industry • Planning for change- watch for new developments, change in technology, supportive personality
