Tool Support for Product Derivation in Large-Scale Product Lines: A Wizard-based Approach

A vehicle door structure having an exterior surface of a door window located flush with an exterior surface of a door frame. The door window is vertically displaced in the door frame with the aid of a slider which is fixed to the end portion of the door window. The slider has a vertically extending groove therein into which the end portion of the door window is located. An adhesive is provided between the end portion of the door window and the inside of the slider to fix the door window to the slider. The door window is firmly fixed onto the slider by alternative or conjunctive means such as an enlarged bottom portion of the slider which contacts an end portion of the door window, or a stopper integrally provided on at least one end of the slider and a plurality of ribs which are horizontally disposed at different vertical positions in the groove of the slider. These alternative/conjunctive means serve to absorb stresses which occur from exterior forces experienced by the vehicle door structure.
