Abstract
Vgradni espresso kavni aparat je aparat, ki se ga uporablja v hišnem gospodinjstvu. Posega v višje cenovne razrede kuhinjskih naprav, od katerih se pričakuje najnaprednejše digitalne in avtomatizirane rešitve, ki uporabniku čim bolj poenostavijo uporabo in vzdrževanje. Tako je bila prepoznana zahteva po avtomatskem pomiku iztoka kave na optimalno višino posameznega napitka in podstavljene skodelice. V okviru magistrskega dela smo na obstoječ ročni pomični sistem implementirali avtomatski pomični sistem. Nov sistem smo ločili na dva podsistema: sistem za pomik iztoka in sistem za detekcijo objekta. Začeli smo z analizo trga kavnih aparatov z avtomatskim pomikom iztoka in nato definicijo funkcijskih zahtev novega sistema. Sledilo je generiranje idej s pomočjo možganske nevihte. Na tem mestu smo se preusmerili v razvojni proces zgolj prvega podsistema. Tvorili smo prve koncepte in jih ovrednotili. Za tri najboljše smo nato izdelali funkcijske prototipe, ki smo jih testirali in izkustveno vrednotili. Tako smo dobili zmagovalni koncept, kjer avtomatski pomik iztoka omogoča kombinacija zobate letve in zobnika, ki je gnan s pomočjo elektromotorja. Za ta koncept smo izdelali detajlni model, ki omogoča vgradnjo v model obstoječega kavnega aparata.

Title:Development of an automatic height adjustment of coffee outlet for a built-in espresso coffee machine
Abstract:
A built-in espresso coffee machine is a machine used in the household. It is a higher-end kitchen appliance that is expected to offer the most advanced digital and automated solutions to make use and maintenance as simple as possible for the user. Thus, the requirement for an automatic adjustment of the coffee outlet to the optimal height for each selected beverage and cup was recognized. As part of the master's thesis, we implemented an automatic sliding system within the existing manual sliding system. The new system was separated into two subsystems: an outlet motion system and an object detection system. We started by analyzing the market for coffee machines with an automatic height adjustment of the coffee outlet and then defining the functional requirements of the new system. This was followed by idea generation through brainstorming. At this point, we turned our attention to the development process of the first subsystem only. First concepts were generated and evaluated. The three best ones were then prototyped, tested, and evaluated experientially. This resulted in the winning concept where the automatic movement of the coffee outlet is made possible by a combination of a rack and pinion driven by an electric motor. For this concept, we produced a detailed model that allows the model to be integrated into an existing coffee machine.
