I coiled and uncoiled my earbuds in different ways and made several quick sketches for storage objects as a way to understand the issues involved. Here are sketches that show two options I will be testing.

In the first version, the wires wrap completely around the Inner Support:

In the version above, I noticed that the thin wires were at risk of being pulled too tightly around the edge of the Inner Support card and might kink. In the second version, I decided to try two relatively large posts for the wires to wrap around, thus eliminating any sharp bends.

1. A way to store my house and bike lock keys in my bag that keeps them easily accessible when I am on my bike
   
2. A way to maintain consistent hedge height while pruning
3. Better/faster earbud storage system
4. A way to sync my grocery list with the actual food in my house
5. An outdoor water dish that the dog can refill when it gets empty
6. A wall-mounted guitar hanger that holds the guitar more securely and is aesthetically pleasing
7. A non-tacky way to encourage people who park in front of my house to pull forward enough that a second car can also fit
8. A way to capture fumes from spray paint and other finishes in my basement that can also be stored away easily
9. A better system for neatly storing shoes by the door at my house
10. A better way to deal with laundry that needs to be dried flat, particularly when there are several items at one time

For the course, I plan to develop a design for 3. Better Earbud Storage. More can be found at My Gap.

These are my earbuds. I love them because they sound excellent, look great, and they seal out outside noise. They have an inline remote that works well with my phone. They are well made, and I expect them to last longer than others I have owned.
