  1. Unit 3 Updated 1-8-14 Mac Steelman

  2. The Big Idea • Systems thinking enhances the technological design process by emphasizing the relationships among a system’s parts.

  3. Objectives: Identify and describe the resources for tech. design. Analyze technological systems. Solve a problem using the technological design process. Develop a design proposal. Develop a design portfolio.

  4. Lesson 1: Systems and Resources • Students will understand the relationship between systems and resources and the technological design process.

  5. Systems Thinking Requires:

  6. Logic

  7. Creativity

  8. Compromise

  9. Components of a System • Feedback Loop • Complex Systems have layers of controls that operate particular parts of a system or control that operate parts of the system. • Fully automatic systems require human control at some point. • Stability of a system can be greater with the appropriate feedback mechanisms.

  10. Product/System Requirements • Identification of criteria and constraints • Criteria and constraints affect the final design and development of products and systems

  11. System Complexity • The more parts a system has, the more opportunity there is for failure. • Complex systems may be able to detect, backup, bypass, or even compensate for minor failures.

  12. Patenting Process

  13. The patenting process allows an individual or company to claim full rights to an invention of their own. • Parts, Products, Music, Logos, Processes • Protection from idea and invention theft. • Increases economic growth though business stability

  14. Pick a congested city of your choice. • Research Demographics (Brief History, Population Density, Ethnic Groups, Infrastructure, and so on) • Collect Various images of the city (Include Ground level views, Google Maps, Google Earth) • Discuss the problem of congestion and the outcome of designing an elevated monorail system that would reduce congestion. • Sketch a monorail along with how many passengers it will transport. • Sketch the elevated rail system and what it will be constructed of and why. • Use Google earth or maps to draw a rail system around and within the city. In Class Group Project: Design an Elevated Monorail Work in groups of 2 and complete the following assignment. The assignment is to be compiled into a portfolio. Order will include: Cover Sheet Demographics Google Images (Aerial and Maps) Elevated Monorail Sketch Rail System design Estimation of how many pedestrians could ride every day.
