The theme of the project “Research on the development of a multi-device type device for people with special needs” involves an intelligent haptic system that helps the blind, able to simulate the Braille alphabet and transmit user commands to an electronic device. The product resulting from this process is useful for people with special needs. Following the study carried out in this paper, a series of constructive-functional variants were analyzed for this type of product, from which the only variant was chosen, as the optimal variant. This analysis also included products competing with our device, and thus resulted in a product that has twelve components made physically with the help of additive manufacturing technology. With the help of 3D printing, we managed to have a product design model and continue its development, making it functional. The appearance of the automatic typing system is like a cropped box or a kind of miniature 3D printer, to make room for rods that help coordinate movements. The functionality of the product requires of electronic elements, but also a software that allows the recognition of the Braille alphabet.
