Don't let the conceptual model come to fruition without basing design around the mental model of a user.
If the product is new, or the conceptual model does not fit with the mental model of the audience you need to then provide training, how-to's, etc. for the user to create a new mental model of the product that aligns closer with the conceptual model.
