Unless the obj_i_a and obj_i_b are totally unrelated (very unlikely), I think this might/should be refactored so that the decision between each obj_i_a and obj_i_b is done in a separate obj_i_factory callable. If you provide an example or two of specific triples (type_of_obj_i, obj_i_a, obj_i_b), we'll have a better idea of whether factories are an overkill in this case or not.
