  In this work we study kinklike structures, which are localized solutions that
appear in models described by real scalar fields. The model to be considered is
characterized by two real scalar fields and includes a function of one of the
two fields that modifies the kinematics associated to the other field. The
investigation brings to light a first order framework that minimizes the energy
of the solutions by introducing an auxiliary function that directly contributes
to describe the system. We explore an interesting route, in which one field
acts independently, entrapping the other field, inducing important
modifications in the profile of the localized structure. The procedure may make
the solution to spring up as a kinklike configuration with internal structure,
engendering the important feature that also appears directly connected with
issues of current interest at the nanometric scale, in particular in the
electronic transport in molecules in the presence of vibrational degrees of
freedom.
