  In this paper we study the possibility of constructing two-field models from
one-field models. The idea is to start with a given one-field model and use the
deformation procedure to generate another one-field model, and then couple the
two one-field models nontrivially, to get to a two-field model, together with
some explicit topological solutions. We show with several distinct examples
that the procedure works nicely and can be used generically.
