Introduction
Have you ever heard the Ben Franklin quote “remember that time is money”? That applies to design as well, taking your time to follow the design process is time well spent so you can turn a profit, or make money, on your design.
In this activity you will design a watch or other piece of jewelry that tells time. It is important for you to remember what you learned about measuring, sketching, drawing, and using software in previous lessons and activities. You may want to refer back to your notes in your GTT notebook if you need help on an idea or design process.
Equipment
· GTT notebook
· Pencil
· Computer with 3D modeling program
· Sketch paper
Procedure
In this activity you will design a watch in orthographic views including appropriate measurements. Then sketch it using the 3D modeling software, and create the appropriate working drawings so a watch-maker could make the product you designed.
Your team’s watch design must include the following design constraints:
· An appropriate size for a teenager to wear it.
· Include special design traits, such as
o A clasp or way to attach it
o An appropriate way to view the time
o Fillets or chamfers that add to the design
o Rounded edges for safety
In order for you to know how to create the holes, counterbore, countersink, fillets, and rounds for this project, you will follow the instructions of your teacher or complete the tutorials regarding these topics.
Follow the design process as you develop your ideas. Complete the attached Watch Design Brief, Decision Matrix, and Design Process Solution pages as you work on your watch design.
Be sure to include entries in your engineering notebook for every day that you work on this project.

Conclusion
1. What was the hardest part about designing a watch?
2. If you were given more time, what would you like to change about your watch design?
3. When creating the working drawings of the watch, list the important steps to remember.

4. In the criteria boxes, list the criteria from your design brief.
5. Under the ideas boxes, put your three ideas and your partner’s three ideas – label the sketches A, B, C, D, E, and F.
6. Evaluate the design idea for all criteria, giving each a value between 1 and 4. 1 means the design does not meet the criteria; 4 means that this is the best possible solution to the problem for this specific need.
7. If your criteria is a question, use 1 if the answer is no and 2 if the answer is yes.
8. When you finish evaluating your sketches, add the numbers across and put your answer in the Total column.
9. The design with the highest total is your Best Solution.
