The gap I selected is that...
- I always feel annoying that I need to use paper bag to bring my clothes to school to change
- It is not very convenient as it can be teared and get wet easily 
- Not very environmental friendly because it is made of wood
- Bag made of fabric is washable and can be used many times comparing with paper bag
- the Bag has to be in suitable size, not too big or too small, a size that is just right

Below is my design of the Bag I am going to create:

10 gaps that annoy me...

-A Bag for carrying my clothes that are needed to bring to school
-A detail Calendar used for time management of school assignments
-A Box that can be used to contain small sewing materials such as rolls of trend and needles etc.
-A little Bag for containing earphones or even phone while going to trip
-A Container for different types of electric chargers without mixing up
-A Three-layer Filing cabinet for storing different kinds of paper in case the paper are all mixed up
-A Book for listing different types of languages of songs in my electric devices
-A CD or DVD container that is used to store different types of discs without their covers to reduce the space needed
-A Container in the shape of round cylinder that can contain stationeries used daily such as pens, markers and etc
-A Shelf for hanging belts that have different lengths and colors

The chosen gap and the way to solve it...
*A bag for carrying my clothes that are needed to bring to school
  Every week, there are several days that I need to bring my Physical Education attire to school to get changed during break time which lasts less than 5 minutes. As it is quite short for most of the classes in my grade to change at the same time, I would love to have a bag in a suitable size. So it can be brought downstairs and get changed near the gymnasium. This can reduce the time taken for waiting other people to get changed and I will not need to use paper bags that are not very environmental friendly.

  The picture beside is Stainless Steel Vacuum Bottle (Mug). It can store water at a certain temperature longer. For example, during winter, it can keep water hot or cold for hours. It takes minimal space with maximizing capacity. Also, it is special because the stainless steel vacuum insulation keeps beverages hot or cold for hours. Last but not least, it has a safety lock in case I opened the bottle accidentally. These are the reasons why I love this water bottle that I use everyday!
