My ten gaps:

1. A pair of women shoes that can be transformed depending on the situation she needs. High-heels to flats, solid colour to polka-dot pattern, etc)
2. A better design of bags for students that carry heavy books. A solution to make the bag less heavy.
3. A special bag for architecture students who need to carry a lot of things to university such as huge plans, drawing equipment, books, etc.
4. A way of organizing my wardrobe  separating winter, atoumn, summer and spring clothes.
5. A teddy bear with secret space for saving money.
6. A stylish, modern and safe artifact where I can save my glasses.
7. An artifact that can help a mother carry all the baby's things and not forget her beauty and health staff. 
8. A solution for people who love working in bed but find it disorganized.  (***)
   
9. A solution for people who hate getting up to get the remote control.
10. A more efficent piece of furniture for people who work in the kitchen. A place where they can organize better their cooking-tools.

I firmly believe that the ladder has been one of the most interesting artifacts created by human-kind. It allows a person to reach difficult places and what I really enjoy about this artifact is that it can be used by construction workers, housewife, children and almost anyone. It is practical, it doesn't occupy much space, it's helpful, light-weighted and long-lasting.
