1. 1/9 What is the purpose for keeping an accurate and complete design journal? –Including Signature Sketches (rough and refined) Notations Test results Written in pen

2. Using an Engineering Design Journal

3. Guidelines for an Engineering Design Journal All entries are dated and signed by the engineer If an idea is marketable, the entries should also be signed by a witness Use a pen instead of a pencil so that ideas cannot be altered Do not erase anything Fill in large blank spaces with Xs Create all drawings to scale!

4. Annotating Sketches Write clarifying notes Indicate if the drawing is a rough draft Include a scale for every drawing Label key parts of drawings Explain the functions of different parts Add arrows to show movement Fill in large blank spaces with Xs Create all drawings to scale!

5. Inventing a New Kind of Pencil What is wrong with this pencil? Too small No eraser Lead always breaks Needs sharpening

6. What new features can we add to make it more useful? Put on an eraser Make the eraser bigger Make it longer Make it skinnier

7. What about these pencils? Put on an eraser Make the eraser bigger Make it longer Make it skinnier

8. Purpose of Sketching Visual brainstorming A fast way to work out new design ideas Creating a visual record of your ideas A method of communicating your ideas to others “Protect” your ideas

9. Sketching lines, shapes and forms

10. Sketching Orthographic (Two-dimensional objects) Isometric (Three- dimensional objects) Rough drafts (as opposed to scale drawings) Scale drawings/objects

11. Future History How will an every-day item change in the next 20 years? 2008 Acura Sedan 2031?

12. A Refrigerator Wired to Internet?

13. A narrative is written to describe the object and how it has changed. Include potential desired and undesired outcomes as a review from the first unit. Create sketches of the new object, as it is today and what it may look like in 20 years. All information is recorded in the Engineering Design Journal.

14. How will cell and telephones change? Recent telephone advances –Fiber optic cables rather than coaxial cables –Prestored numbers, call waiting, caller id, and simultaneous voice and text communication –4G technology that allows live video viewing from cell phones –Wireless Application Protocol (WAP) provides access to internet via telephone

15. Future Communications Narrative Think about how communication devices have changed in your lifetime How may communication devices change in 20 to 30 years? Write a BCR of at least five sentences Prepare a written description of your future communications device Make a scale drawing of your future communications device

16. Mobile and Cell telephones

24. Future Technology Design Identify a product or service that you find interesting How may that device or service change in 20 to 30 years? Write a BCR of at least five sentences Prepare a written description of your future device or service Make a scale drawing of your future communications device

25. LuminAID Solar Light

31. How will these change?
