  1. UNIT 3 Engineering Design:Getting Familiar with the Big Idea Foundations of Technology

  2. Standard 5.0 • Apply the Engineering Design Process

  3. Clear Target • Students will be able to identify resources, steps in the design process, and the constraints within the engineering design process.

  4. What is this? The Roman Aqueducts. • For what purpose were they built? To supply the city of Rome with fresh water.

  5. The Roman Aqueducts What resources were used to create this engineering accomplishment? • Stone • People • Knowledge of: Construction Geometry Algebra (slope) Gravity

  6. The Roman Aqueducts • Constructed in about 140 B.C. • At the height of the Roman Empire, Rome had over a million people. • These aqueducts brought about 1 cubic meter of water for every person. • It was gravity-fed. There were no pumps that moved the water.

  7. Engineering Resources • Resource – The things needed to get a job done. • These include: • Energy • Capital • Information • Machines and tools • Materials • People • Time

  8. Engineering • Engineering – • the systematic application of mathematical, scientific, and technical principles, to yield products that meet our needs and desires.

  9. Engineers • Engineers are… • problem solvers. • Engineering has evolved from generation to generation. Each new generation builds on the knowledge of the previous generation. • Engineers are: • Creative • Resourceful • Can think “outside of the box”

  10. Constraints • Constraint – • A limit to the design process. • Constraints include: • Specifications • Funding • Space • Materials • Human capabilities

  11. Principles of Design • Design is the result of a formal, sequential process. • Design problems seldom arise in a clearly defined form. • Design is driven by profit motive and market. • Design requirements sometimes compete with each other. • Design is the result of goal-oriented research. • Designs must be continually checked, refined, and improved.

  12. Product Life-Cycle • When designing a device, you must consider every aspect of the manufactured product. • Thought should be given to how it will be manufactured, operated, maintained, replaced, and disposed of and who will sell, operate, and take care of it.

  13. Assignment Students will develop a brief (500-750 word) essay on one of the “Greatest Engineering Achievements of the Twentieth Century” that will address the following topics: • The need or desire that led to these projects. • The resources used to create the project. • The constraints that impacted the development of the project.
