a solution/design pattern for approching meny devices

[zevikbe]

a lot of logic objects need to approch to meny devices.
the solution today: interface class to implemented in a single class containg all the dfevices.
Problem: the interface becomes a garbage collector.

question: each logic class needs to approch to only few devices.
the logic class need to stay encapsulated from devices.
there are devices whice serve several logic classes

Do someone have a solution/design pattern to this problem ?

If the interface "becomes a garbage collector", why don't you just require logic objects to call a dispose method when they're finished with a device? In that way the interface can remove devices when they're no longer in use.

the problem is with the interface not with the number of devices
