The wedge is a term for a common situation involving three or more blocks lined up next to each other, with one open row behind them including an item for Chip to collect, or other such goal: Assuming there is no other way to reach the chip in this area, the way to collect the computer chip is to move the two side blocks out of the way, then the central block in either direction. There are many types of wedges in Chip's Challenge, as seen by the different levels where they occur.
