In this work, one possible linkage way between the classical and the 3D-CAD based design educational methods is proposed. Concretely, optimal design under imposed constraints of a worm gear screw jack (WGSJ) is taken as the design problem to be solved. Optimal design is sought under two main conditions: to maximize the efficiency of WGSJ, for energy saving, and to minimize the overall size of WGSJ, for compact design. In the classical design educational method, practical training on the assembling-disassembling of the WGSJ is followed by the training on the freehand sketching of the main parts of WGSJ, followed then by the training on the modeling and strength calculus of the parts, performed in parallel with the preparation of the scheme drawings, and the educational process is completed by the training in the assembly and part drawings. As proposed in this work, the training process on the modeling, strength calculus, and drawings preparation can be substantially aided by using the Solidworks software. Additionally, quality of the educational process can be properly evaluated by using a 3D-printer to manufacture (print) the designed parts.
