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
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. AGRICULTURAL AGE
INDUSTRIAL AGE
INFORMATION AGE
-began about 10,000 yrs ago
Began around 1750bc
Began around 1850
Economy based upon growing crops
Economy based on manufacturing
Economy based on knowledge
Key inventions:
Plow
Loom
Reading & writing
Measurement
Steam engines
Blast furnace
Mass production
Train, plane automobiles
Skyscraper
Telephone, radio, TV
Computer
Internet/web
Key Impacts:
Growth of towns and cities
Specialization in jobs
Most people work where they live
Public schools
People move from farms and villages to cities
Greater productivity- lower priced goods
Most people travel to work
Electronic business and education
Globalization
Work goes with you

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

8. DESIGN- the process of creating things by planning

9. 2 ways to design: Invention- new idea Innovation- improvement
Example- CD player innovation of the phonograph (Edison)

10. The Design Process:

11. 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?

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

13. 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

14. 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

15. 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?

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

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

18. 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

19. 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

20. 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

21. 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

22. 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

23. 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

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