In the picture below, you can see the effect of extra edges placed where you need a surface to keep its shape, that is, have sharper corners or edges. The bottom row has a smoothing modifier on it. So you have to cut more edges (or use Loop Cut as edna said), where you need an edge or corner to be sharper.

The modifier is doing what it is supposed to. So the answer depends on what you were expecting. Experiment with one or all of these to get the result you are after:

  1. Changing the modifier to Simple rather than Catmull-Clark;
  2. Increasing the number of Subdivisions in the modifier;
  3. Adding vertices (e.g. using Loop Cut in edit mode) to sharpen corners/edges.
