can't we just have a SmartDevice interface which will be implemented by different types of smart devices, and a connector interface which will have bluetooth, wifi etc as implementation ?

each smart device can have a single or multiple connectors
now we can use dependency injection in the constructor of smart devices to inject the type of connector we want? and then we can use the connect function to connect via it.

which would result in even lesser code than adapter pattern in this case, and also result in an extendible code.

How many design pattern are there? Which is important from interview point of view
