The Bridge Pattern is a structural design pattern that aids in the separation of an abstraction (high-level control logic) from its implementation (low-level functional logic), allowing both to be varied independently. This separation increases modularity and improves code maintainability.

We can better understand this pattern by using an example problem and its solution.

Consider an example of a class hierarchy involving some vehicles and their transmission systems. We will go through this class hierarchy with and without the use of bridge pattern.
