I read about a great trick in The Complete Book of Anchoring and Mooring
, a book I would recommend.
You can use the rode itself as a trip line. You need an eye on the crown of the anchor. Instead of shackling to the end of the arm, you shackle to the crown, and then seize the rode onto the end of the arm with a line that can break under sufficient pressure. If the anchor doesn't get stuck, same as anchoring without a trip line. If it does, then when you weigh, the seizing breaks and now the rode pulls the anchor out backwards.
I forget what it's called. I think it was often used on traditional stock anchors, but I don't see why it couldn't be used on a modern anchor with sufficient modifications.
